Newborn Resuscitation (NLS 2021)

NLS 2021 · Apgar score · 5 inflation breaths · 3:1 compressions · Room air start · Therapeutic hypothermia

NLS 2021 · RCUK · ILCOR 2020

85% of newborns need only drying and stimulation. 10% need airway and inflation breaths. ~1% need chest compressions. Call for help early — better to have help and not need it.

📋 NLS Algorithm — Step by Step
  1. ADRY & STIMULATE. Warm towels. Remove wet towel. Rub back and soles of feet. Note time of birth. Call for help.
  2. BASSESS at 60 seconds: Breathing? Heart rate >100? Tone? If breathing well and HR >100 → routine care / skin-to-skin.
  3. CAIRWAY. Neutral position (NOT hyperextended). Jaw thrust if no response. Two-person airway technique preferred for masks.
  4. D5 INFLATION BREATHS via face mask + T-piece or self-inflating bag. Each breath 2–3 seconds. Pressure 30 cmH₂O. Start in room air (21% O₂). Watch for chest movement.
  5. EASSESS RESPONSE. HR rising → ventilation breaths 40–60/min. No chest movement → recheck position, try 2-person jaw thrust, check for secretions, try longer inflation breaths. Consider intubation.
  6. FHR <60 after 30 seconds of effective ventilation → Chest compressions: 3:1 ratio (90 compressions + 30 breaths = 120 events/min). 2 thumbs encircling chest. Depth 1/3 AP. Intubate. Increase O₂ to 100%.
  7. GDRUGS if HR still <60: Adrenaline 10–30 mcg/kg IV/IO/UVC (1:10,000: 0.1–0.3 mL/kg). Repeat q3–5 min.
  8. HREVERSIBLE CAUSES: Hypovolaemia (10 mL/kg 0.9% NaCl), Pneumothorax (needle decompression), Hypoglycaemia (2 mL/kg 10% dextrose), Hypocalcaemia.
Apgar Score (Assess at 1 & 5 min)
Each component scored 0–2: Heart rate · Respiratory effort · Muscle tone · Reflex irritability · Colour
7–10: Normal | 4–6: Moderate — stimulation, O₂, inflation breaths | 0–3: Severe — immediate resuscitation
O₂ Titration Targets (NLS 2021)
Start 21% air (term and near-term >35 weeks). Pre-ductal SpO₂ (right hand): 2 min 60%, 3 min 70%, 4 min 80%, 5 min 85%, 10 min 90%+
Preterm <32 weeks: start 30% O₂. Avoid hyperoxia — increases mortality. Titrate against SpO₂ targets.
Therapeutic Hypothermia (HIE)
Criteria: ≥36 weeks + moderate/severe HIE + within 6h of birth. Core temp 33–34°C for 72h. Reduces death/disability ~25%.
Do NOT actively warm — passive cooling. Transfer to cooling centre. If distant: cooling blanket/packs to axillae/groin.

Newborn Cardiac Arrest

NLS · 3:1 ratio · Adrenaline via UVC · Reversible causes · Sodium bicarbonate

NLS 2021 · ILCOR
🚨

Neonatal arrest is almost always respiratory in origin. Effective ventilation is the single most important intervention. 3:1 compression:ventilation ratio is unique to neonates. UVC is the preferred vascular access route.

💊 Drugs & Reversible Causes
Adrenaline (Epinephrine)
IV/IO/UVC: 10–30 mcg/kg (= 0.1–0.3 mL/kg of 1:10,000 adrenaline). Repeat every 3–5 min.
Endotracheal route NOT recommended (unreliable absorption)
Volume Replacement (if Hypovolaemia Suspected)
0.9% NaCl or O-negative blood: 10 mL/kg IV/IO over 10–20 min
Suspect if: cord prolapse, abruption, feto-maternal haemorrhage, pale despite O₂
Dextrose
10% dextrose: 2.5 mL/kg IV/IO if BM <2.6 mmol/L
Sodium Bicarbonate
4.2% NaHCO₃: 1–2 mmol/kg (= 2–4 mL/kg) only after effective ventilation is established. UVC preferred. Avoid peripheral extravasation.
4Hs and 4Ts — Reversible Causes
Hypoxia (most common — ensure effective ventilation first), Hypovolaemia, Hypoglycaemia, Hypothermia
Tension pneumothorax (needle decompression), Tamponade, Toxins (opioid → naloxone 200 mcg IM/IV — NOT if mother on methadone), Thrombosis

Paediatric Cardiac Arrest (APLS 2023)

15:2 CPR · 4 J/kg shocks · 5 rescue breaths first · Adrenaline · Amiodarone · IO access

APLS 2023 · RCUK · ILCOR 2020
🚨

Paediatric arrest is usually asphyxial (respiratory first). Shockable rhythms (VF/pVT) occur in only ~10%. Give 5 rescue breaths BEFORE chest compressions. Oxygenation is the priority.

📋 APLS 2023 Algorithm
  1. 1Unresponsive, not breathing normally? Call resus team. Start timer. Open airway.
  2. 25 RESCUE BREATHS (1–1.5 seconds each, visible chest rise). Check for signs of life / HR after breaths.
  3. 3No signs of life or HR <60 with poor perfusion → 15 compressions : 2 breaths. Rate 100–120/min. Depth: 4 cm infant / 5 cm child (1/3 AP diameter).
  4. 4Attach defibrillator pads ASAP. Assess rhythm every 2 minutes.
  5. 5SHOCKABLE (VF/pVT): 4 J/kg unsynchronised. Resume CPR immediately. After 3rd shock: give adrenaline + amiodarone.
  6. 6NON-SHOCKABLE (PEA/Asystole): Adrenaline 10 mcg/kg IV/IO immediately, then every 3–5 min. Treat reversible causes.
  7. 7IO access: tibial plateau (anterior, 1 cm below tibial tuberosity medially) or distal femur. Confirm position → flush with 5–10 mL NaCl. Intubate only if skilled operator — do not stop CPR.
Drug Doses During Arrest
Adrenaline 1:10,000: 0.1 mL/kg IV/IO (= 10 mcg/kg). Max 1 mg per dose. Every 3–5 min (shockable: from 3rd shock; non-shockable: immediately)
Amiodarone: 5 mg/kg IV/IO after 3rd shock and after 5th shock. Max 300 mg. Dilute in 5% dextrose.
Calcium chloride 10%: 0.2 mL/kg IV/IO — only for hypocalcaemia, hyperkalaemia, or Ca-channel blocker OD
Magnesium 50% (0.1 mL/kg = 25 mg/kg): Torsades de pointes / hypomagnesaemia
Post-ROSC Care
SpO₂ 94–98%. PaCO₂ 4.5–6 kPa (normocapnia — avoid hyper/hypoventilation). Glucose 4–8 mmol/L.
Temperature: normothermia 36–37°C. Avoid fever. THAPCA trial: cooling not superior to normothermia in children.
PICU referral. 12-lead ECG. Echo. Consider underlying cause.

Paediatric Tachyarrhythmias

SVT · Adenosine weight-based · DC cardioversion · VT · Torsades

APLS 2023 · RCUK
📋 Assessment & Treatment Algorithm

Haemodynamically Unstable

Shock, altered consciousness, signs of low output → immediate synchronised DC cardioversion regardless of diagnosis.

Narrow Complex (SVT)

HR >220 infant / >180 child. Regular. No P waves visible. Try vagal → adenosine.

Broad Complex Tachycardia

Treat as VT. Do NOT give adenosine in broad complex — may precipitate VF in WPW+AF.

Step 1 — Vagal Manoeuvres
Ice to face (diving reflex): bag of iced water over face for 15 seconds — most effective in infants. Do NOT occlude airway.
Valsalva (older children): blow through straw or syringe against resistance for 15 seconds.
Step 2 — Adenosine (Rapid IV Bolus + Immediate Large Flush)
1st dose: 0.1 mg/kg IV (max 6 mg). Rapid bolus into large vein — antecubital or central. Follow immediately with 5–10 mL NaCl flush.
2nd dose: 0.2 mg/kg IV (max 12 mg). Wait 1–2 minutes. Warn patient: chest tightness, flushing, transient feeling of doom, asystole pause 3–10 seconds.
3rd dose: 0.3 mg/kg IV (max 18 mg). Defibrillator on and ready.
Contraindications: asthma (relative), 2nd/3rd degree AV block, known WPW + AF, sick sinus syndrome.
Step 3 — DC Cardioversion
SVT: 1 J/kg synchronised → 2 J/kg. Sedate first if conscious: ketamine 1–2 mg/kg IV or midazolam 0.1 mg/kg IV.
Adenosine refractory SVT: amiodarone 5 mg/kg over 30 min or flecainide (specialist only).
VT Management
Pulseless VT = VF protocol (4 J/kg unsynchronised). Pulse present: amiodarone 5 mg/kg IV over 30 min OR synchronised cardioversion.
Torsades de pointes: MgSO₄ 25–50 mg/kg IV (max 2g) over 2–5 min. Correct K⁺ and Mg²⁺. Overdrive pacing if recurrent.

Hypovolaemic Shock in Children

APLS 2023 · 10 mL/kg bolus · Max 40 mL/kg crystalloid · Blood products · Vasopressors

APLS 2023 · NICE NG29 · FEAST trial

FEAST trial: 20 mL/kg boluses in severe febrile illness increased mortality. APLS now recommends 10 mL/kg boluses with reassessment after each. Maximum 40 mL/kg total crystalloid before starting vasopressors in septic shock.

📋 Recognition & Fluid Protocol

Compensated Shock

Tachycardia. Normal BP. CRT >2s. Mottled/pale skin. Oliguria (<1 mL/kg/h). Children compensate until 25–30% volume lost — act before BP drops.

Decompensated Shock

SBP < 70+(age×2) mmHg. Altered consciousness. Absent peripheral pulses. IV/IO access NOW. Vasopressors if no response after 40 mL/kg.

Fluid Resuscitation Protocol
Bolus 1: 10 mL/kg Hartmann's IV/IO over 10–15 min. Reassess: HR, CRT, BP, consciousness immediately after.
Bolus 2: Not improving → repeat 10 mL/kg. Total 20 mL/kg. Reassess.
Bolus 3: Not improving → repeat 10 mL/kg. Consider blood products now. Total 30 mL/kg.
After 40 mL/kg: Start vasopressors. Give blood 1:1:1 (pRBC:FFP:platelets). No further plain crystalloid.
Blood Transfusion
Haemorrhagic shock: give O-negative blood early — do not wait for cross-match. 10 mL/kg pRBC over 30–60 min (raises Hb ~10–15 g/L).
Transfusion threshold: Hb <70 stable / Hb <100 if haemodynamically compromised or ongoing bleeding.
Vasopressors (After 40 mL/kg Crystalloid in Sepsis)
Noradrenaline: 0.05–0.5 mcg/kg/min IV infusion. Central line preferred; IO acceptable short-term.
Adrenaline: 0.05–0.5 mcg/kg/min — if cardiogenic component suspected or poor response to noradrenaline.
🫀

Duct-Dependent Congenital Heart Disease

Alprostadil (PGE1) · Cyanotic neonate · Apnoea risk 10% · Intubation readiness

APLS · BCS · RCPCH
🚨

Any cyanosed neonate not responding to 100% O₂, or collapsing in first 2–3 weeks, may have duct-dependent CHD. Start alprostadil IMMEDIATELY. Prepare for apnoea (10–12%) — intubation equipment at bedside at all times.

📋 Lesions, Diagnosis & Management
Duct-Dependent Lesions
Pulmonary blood flow dependent on duct: Pulmonary atresia, critical PS, tricuspid atresia, severe Ebstein's, severe Tetralogy of Fallot
Systemic blood flow dependent on duct: HLHS, critical aortic stenosis, severe coarctation, interrupted aortic arch
Parallel circulation (TGA): duct-dependent mixing — emergency balloon atrial septostomy (Rashkind procedure)
Hyperoxia Test (Diagnostic)
Pre-ductal (right hand) SpO₂ vs post-ductal (either foot). Difference >3% = significant right-to-left shunt.
Give 100% O₂ for 10 minutes. PaO₂ <20 kPa despite 100% O₂ = likely cardiac (not respiratory). Avoid prolonged hyperoxia — may close duct.
Alprostadil (PGE1) Infusion — Start Immediately
Starting dose: 5–10 ng/kg/min IV continuous infusion. Dilute in 5% dextrose. Dedicated IV line.
Increase to 20 ng/kg/min if no response. Max 100 ng/kg/min. Effect may take 20–30 min.
Side effects: Apnoea 10–12% (intubation must be immediately available), fever, hypotension, flushing, jitteriness, seizures (reduce dose).
Urgent paediatric cardiology/NICU discussion. Transfer to PICU/cardiac surgical centre once stabilised on alprostadil.

Paediatric Asthma

BTS/SIGN 2023 · Salbutamol · Ipratropium · Magnesium 40 mg/kg · PICU criteria

BTS/SIGN 2023 · NICE NG80
🔬 Severity Assessment

Mild

SpO₂ ≥94%. Full sentences. PEFR >75%. Mild wheeze. HR <100 infant / <120 child.

Moderate

SpO₂ 92–94%. Phrases. PEFR 50–75%. Accessory muscles. HR 100–130.

Severe

SpO₂ <92%. Single words. PEFR <50%. Severe tachycardia. Cyanosis. Paradoxical breathing.

Life-Threatening

SpO₂ <92% on O₂. Silent chest. Poor respiratory effort. Confusion. Bradycardia. PICU NOW.

Under 5s: viral-induced wheeze more common than true asthma. Ipratropium NOT routinely used under 2 years. Salbutamol via spacer/mask as effective as nebuliser in mild-moderate.

💊 Treatment by Severity
O₂ — All Patients With SpO₂ <94%
Target SpO₂ 94–98%. High-flow O₂ via tight-fitting mask if required. Continuous pulse oximetry.
Salbutamol (All Moderate+)
<5y: 2.5 mg neb q20 min × 3 in first hour. ≥5y: 5 mg neb q20 min × 3. Then q1–4h.
Alternatively: 6–12 puffs salbutamol MDI via spacer — equivalent efficacy to nebuliser in mild-moderate.
Ipratropium (Severe/Life-Threatening — Added to Salbutamol)
<5y: 0.125 mg q20 min × 3. ≥5y: 0.25 mg q20 min × 3. Then q4–6h.
Steroids (All Moderate+ — Give Early)
Prednisolone oral: 1–2 mg/kg/day (max 40 mg) for 3–5 days. Give in ED, do not wait.
Vomiting / unable to swallow: dexamethasone 0.15–0.3 mg/kg oral (equally effective, less vomiting).
IV: hydrocortisone 4 mg/kg q6h (max 100 mg) if oral not possible.
Magnesium Sulfate (Severe / Life-Threatening)
MgSO₄ 40 mg/kg IV (max 2g) over 20 min. Single dose. Reduces PICU admission in severe attacks (MAGNETIC trial).
Nebulised MgSO₄ 150 mg isotonic solution — additional benefit in severe acute asthma (BTS 2023).
IV Salbutamol (Imminent Arrest)
Loading dose: 5 mcg/kg IV over 5 min. Infusion: 1–5 mcg/kg/min. Monitor for hypokalaemia (correct K⁺).
Intubation (Last Resort)
Call PICU early — warn before the crisis. Ketamine 1–2 mg/kg IV preferred induction agent (bronchodilator).
Ventilate: low RR (12–16/min), long expiratory time, high tidal volume — avoid gas trapping. HELIOX if available.
🫁

Bronchiolitis (RSV)

NICE NG9 2021 · Supportive only · HFNC · Nirsevimab · No salbutamol/steroids

NICE NG9 2021 · RCPCH

Clinical diagnosis — no investigations routinely needed. Salbutamol, steroids, antibiotics, and physiotherapy NOT recommended (NICE NG9). Focus exclusively on: supportive care, adequate oxygenation, and maintaining hydration.

📋 Admission Criteria & Management
Clinical Features
Age <2 years (peak 3–6 months). RSV in 80% of cases. Autumn/winter. Upper respiratory prodrome (1–2 days) → wheeze + crepitations + tachypnoea.
Nasal flaring, intercostal recession, grunting. Feeding difficulty (most common reason to admit). Apnoeas (especially <6 weeks gestation corrected age).
Admission Criteria (NICE NG9)
SpO₂ persistently <92%. Moderate/severe respiratory distress. Feeding <50–75% of normal over 24h.
Apnoeas (witnessed or reported). Clinical exhaustion. Age <3 months (higher risk). Born <37 weeks gestation. Haemodynamically significant CHD or chronic lung disease.
Respiratory Support
Target SpO₂ ≥92%. Low-flow O₂ nasal cannula first line. Avoid painful procedures — worsens distress.
HFNC (Optiflow): start at 2 L/kg/min (max 60 L/min, 34–37°C humidified). Reduces PICU transfer in moderate bronchiolitis (PARIS RCT). Escalate to CPAP/intubation if failing.
Feeding & Hydration
NG feeds if oral intake <75% normal. Avoid oral feeding if RR >70/min (aspiration risk).
IV: 0.9% NaCl + 5% dextrose at maintenance rate if NG not tolerated. Avoid over-hydration.
Prevention
Nirsevimab (Beyfortus): single IM injection — all infants entering first RSV season (UK from autumn 2023). Replaces palivizumab for most.
NOT recommended: salbutamol, adrenaline, steroids, antibiotics (unless secondary bacterial pneumonia confirmed), chest physiotherapy.

Epiglottitis

Do NOT examine throat · Theatre gas induction · Cefotaxime · Now common in adults too

APLS · ENT UK
🚨

DO NOT: examine the throat, attempt IV access in awake child, lay child flat, send to X-ray. ANY disturbance can cause complete obstruction. Keep child sitting upright, blow-by O₂ only, call anaesthetics and ENT IMMEDIATELY.

📋 Recognition & Airway Management
Recognition
Toxic child, high fever (39–40°C), drooling (unable to swallow secretions), dysphonia ("hot potato" voice), tripod posture (leaning forward, neck extended, mouth open). Inspiratory stridor.
Rapid progression over hours (unlike gradual croup). Refuses to lie down. Child appears frightened. HiB vaccination has dramatically reduced UK incidence — now more common in adults and unvaccinated.
Team Call — All at Once
Senior ED doctor + Paediatric anaesthetist + ENT surgeon + PICU. Most experienced person stays with child at all times. Do not leave child alone.
Airway Securing — Theatre
Gas induction with sevoflurane + 100% O₂ in sitting position. Parents in theatre if helpful to keep child calm.
Intubate only once deeply anaesthetised. Use smallest ETT that passes (marked subglottic oedema). Rigid bronchoscopy + emergency surgical airway on standby.
Extubate in PICU after 24–48h when oedema resolves and child tolerates cuff deflation.
Antibiotics (After Airway Secured)
Cefotaxime 50 mg/kg IV q6–8h (max 2g/dose) for 5–7 days. Organism: H. influenzae type B (HiB) in unvaccinated; also Strep, Staph.
Dexamethasone 0.15 mg/kg IV — reduces airway oedema.

Bacterial Tracheitis

Staphylococcal · Croup that deteriorates suddenly · Pseudomembranes · PICU

APLS · RCPCH
🚨

Bacterial tracheitis = croup that went wrong. The child looks TOXIC. Does NOT respond to dexamethasone or nebulised adrenaline. Pseudomembranes obstruct the trachea. High mortality without early intubation in PICU.

📋 Features & Management
Features
Age 1–6 years. Often follows a viral URTI or croup → sudden deterioration with high fever, toxic appearance, stridor, productive cough.
No response to croup treatments (a key diagnostic clue). Barking cough may persist but signs of toxicity distinguish from viral croup.
Organisms: Staph aureus (including MRSA — increasing), Strep pneumoniae, H. influenzae, Moraxella. CXR: steeple sign + subglottic irregularity.
Management
Senior anaesthetics + ENT immediately. PICU bed required. Intubation in theatre (as per epiglottitis protocol). Frequent suction of pseudomembranes required post-intubation.
Empirical antibiotics: Flucloxacillin 50 mg/kg IV q6h (max 2g) + cefotaxime 50 mg/kg q6–8h. Duration 10–14 days.
MRSA suspected: vancomycin 15 mg/kg IV q6h (target trough 10–20 mg/L). Discuss with microbiology.

Laryngomalacia

Most common stridor in infants · Floppy epiglottis · Positional · 85% self-resolve by 18 months

ENT UK · RCPCH
📋 Features, Diagnosis & Management
Clinical Features
Most common cause of chronic stridor in infants. Onset in first few weeks of life. Inspiratory stridor — high-pitched, musical.
Worse: supine, feeding, crying, URTI, agitation. Better: prone, calm, neck extended. Omega-shaped epiglottis on endoscopy.
Feeding difficulties common (poor weight gain). Usually mild and self-resolving by 12–18 months (85–95%).
Red Flags — Urgent ENT Referral
Cyanosis or SpO₂ <93%. Apnoeas. Failure to thrive (weight below 2nd centile or crossing centiles). Severe distress. Cor pulmonale. Feeding requiring nasogastric tube.
ED Management
Reassurance and positional advice (prone, neck extended during feeding). ENT outpatient referral for flexible nasendoscopy (confirms diagnosis and severity).
Admit if: SpO₂ <93%, apnoeas, feeding <50% normal, or acute deterioration suggesting intercurrent illness.
Severe cases: Supraglottoplasty under GA — division of aryepiglottic folds. Effective in 80–95%.

Paediatric Pneumonia (BTS 2022)

Amoxicillin first-line · Empyema · Urokinase · SpO₂ <92% = admission

BTS 2022 · NICE NG143
📋 Diagnosis, Admission & Treatment
Admission Criteria
SpO₂ <92%. Moderate/severe respiratory distress. Unable to maintain oral hydration. Complication (empyema, abscess). Age <3–6 months. Social concerns or poor follow-up possible.
Antibiotics — Community-Acquired Pneumonia
1st line oral (typical CAP — any age): Amoxicillin 40–45 mg/kg/day in 3 divided doses (max 500 mg TDS) × 5 days
Atypical (Mycoplasma — >5y or poor response to amoxicillin): Clarithromycin 7.5 mg/kg BD (max 500 mg BD) × 7 days
Hospitalised IV: Co-amoxiclav 30 mg/kg q8h IV or cefuroxime 30 mg/kg q8h IV × 5 days
Complicated/severe: Ceftriaxone 80 mg/kg OD IV (max 4g) ± clarithromycin if atypical suspected
Staphylococcal (fluffy infiltrates, pneumatocoeles): add flucloxacillin 50 mg/kg q6h IV
Empyema
Suspect if persistent fever despite 48h antibiotics. USS confirms pleural fluid. Send fluid for pH (exudate pH <7.2), LDH, protein, MC&S, AFB.
Chest drain + intrapleural urokinase 40,000 units in 40 mL 0.9% NaCl BD × 3 days (MIST1 trial — superior to drainage alone for fibrinopurulent stage).
VATS decortication if drain fails — direct debridement of loculated empyema. Discuss with paediatric surgery.

Paediatric Pneumothorax

BTS 2010 · Spontaneous vs secondary · Tension · Aspiration · 100% O₂ reabsorption

BTS 2010 · APLS
📋 Management
Types
Spontaneous primary: tall thin adolescent males. Apical bullae. No underlying disease. Recurrence 50%.
Secondary: CF (most common in UK), asthma, staphylococcal pneumonia, Marfan's. Higher morbidity.
Tension: haemodynamic compromise, deviated trachea, absent breath sounds, distended neck veins → treat immediately, do not wait for CXR.
Management by Severity
Tension: Immediate needle decompression 2nd ICS MCL (14–16G). Finger thoracostomy 4th/5th ICS anterior axillary line → chest drain.
Large (>2 cm rim or symptomatic): Needle aspiration (16–18G, 2nd ICS MCL, up to 20 mL/kg aspirated). Failure → small-bore Seldinger chest drain.
Small/asymptomatic: 100% O₂ (increases reabsorption rate 4×). Observe 4–6h. Repeat CXR. Discharge if stable.
Recurrent: VATS pleurodesis (talc or mechanical) after 2nd ipsilateral episode.

Foreign Body Aspiration

Peak 6m–4y · Unilateral wheeze · Button battery = emergency · Rigid bronchoscopy

ENT UK · APLS · RCS
📋 Recognition & Management
Common FBs and Features
Peak age 6 months–4 years. Common objects: peanuts/nuts (organic — swell, cause intense reaction), grapes, toy parts, coins, button batteries.
Acute phase: sudden choking, violent coughing paroxysm, gagging, respiratory distress. May resolve spontaneously — giving false reassurance that FB has been cleared.
Subacute/chronic: unilateral wheeze not responding to bronchodilators, recurrent pneumonia in same lobe, persistent cough. Normal CXR in 30% — inspiratory/expiratory views may show air trapping.
Management
Complete obstruction / unconscious: Back blows + chest thrusts (<1y) or abdominal thrusts/Heimlich (>1y). No blind finger sweeps. CPR if pulseless.
Partial obstruction (coughing): Do NOT intervene — encourage coughing. Intervention may convert partial to complete obstruction. Monitor SpO₂ and RR.
Button battery = EMERGENCY: Immediate rigid endoscopy — liquefactive necrosis begins within 2h. Do not wait. Notify ENT/ORL immediately.
Definitive treatment: Rigid bronchoscopy under GA — simultaneous diagnostic and therapeutic. Flexible bronchoscopy only diagnostic (cannot safely retrieve).

Febrile Convulsions

NICE NG217 2022 · Simple vs complex · LP criteria · Recurrence 30%

NICE NG217 2022 · RCPCH
📋 Classification & Management

Simple (85%)

Generalised. Single episode. Duration <15 min. Full recovery within 1h. Age 6m–5y. Normal development.

Complex (15%)

Focal OR duration >15 min OR recurs within 24h OR Todd's paresis OR age <6 months. Further investigation required.

LP Indications (NICE NG217)
<12 months: Consider LP in ALL first febrile seizures — meningism signs may be absent in infants
12–18 months: LP if meningitis signs, not immunised (Hib/MenC/Pneumo), or clinically concerned
>18 months: LP only if clinical signs of meningitis or encephalitis
Complex: CT head first if focal signs, raised ICP, or not fully recovered. Then LP if no contraindication.
Treatment During Active Seizure
Position safely. O₂. BM. If seizing >5 min: Buccal midazolam 0.3 mg/kg (max 10 mg) or rectal diazepam 0.5 mg/kg
IV/IO available: Lorazepam 0.1 mg/kg (max 4 mg). Treat fever with paracetamol/ibuprofen.
Parental Education & Discharge
Antipyretics: for comfort only — do NOT prevent febrile seizure recurrence. Evidence clear on this.
Recurrence risk 30%. Epilepsy risk: simple FC 1.5–3% (same as general population). Complex FC: up to 10%.
Prescribe buccal midazolam for home rescue if: complex FC, multiple recurrences, or family anxiety. Written action plan.
Admit: complex, age <18 months, uncertain diagnosis, parental concern. Discharge: simple with written advice leaflet.

Paediatric Status Epilepticus

APLS 2023 · Lorazepam · Levetiracetam · Phenytoin · RSI at 25 min

APLS 2023 · NICE NG217
🚨

Status = seizure ≥5 minutes OR recurrent seizures without recovery. Treat at 5 min — do NOT wait 30 min. Each additional minute of seizure = progressive neuronal injury. Have anaesthetics on standby from 15 min onwards.

📋 APLS Algorithm
0–5 min: ABC, O₂, lateral, BM check, positioning, IV/IO access attempt
5 min: FIRST BENZODIAZEPINE
10 min: Still seizing → SECOND BENZODIAZEPINE (same drug, same dose)
15 min: Secure IV/IO → Second-line AED. Call anaesthetics NOW.
25–30 min: RSI — anaesthetics intubate. Thiopentone. PICU.
First-Line Benzodiazepines (Give at 5 min)
IV/IO available: Lorazepam 0.1 mg/kg IV/IO (max 4 mg). Onset 2–3 min. Preferred route.
No IV: Buccal midazolam 0.3–0.5 mg/kg buccal (max 10 mg). Oromucosal. Onset 5 min. (UK licensed as Epistatus/Buccolam)
Rectal diazepam 0.5 mg/kg (max 10 mg). Intranasal midazolam 0.2 mg/kg via atomiser.
Second-Line AED (Give at 15 min, IV/IO)
Levetiracetam 40–60 mg/kg IV/IO (max 3g) over 15 min — now first-line per APLS 2023 (ECLIPSE/ConSEPT RCTs show equal efficacy to phenytoin, better safety)
Phenytoin 20 mg/kg IV/IO over 20 min (max 2g). ECG monitoring. Rate <1 mg/kg/min. Avoid in cardiac arrhythmia.
Sodium valproate 40 mg/kg IV/IO (max 3g) over 5 min — avoid <3 years and girls of childbearing potential (teratogenic).
Third-Line / RSI (25–30 min)
Call anaesthetics immediately at 15 min — do not wait until 25 min to call.
Thiopentone 4–8 mg/kg IV induction (gold standard for refractory status). Propofol 1–2 mg/kg. Midazolam infusion 0.1–0.4 mg/kg/h.
EEG monitoring in PICU. Continue treating reversible causes throughout.

Raised Intracranial Pressure in Children

Cushing's triad · Mannitol 0.5 g/kg · 3% NaCl · Head 30° · Normocapnia

APLS · NICE NG176 · RCPCH
🚨

Cushing's triad (↑BP + bradycardia + irregular breathing) = impending herniation — a LATE sign. Treat raised ICP before this develops. Avoid hypoxia, hypercapnia, hypoglycaemia, hyperthermia, hyponatraemia — all worsen ICP.

💊 ICP Management
General Measures (All Patients)
Head 30°, midline position. Minimal stimulation. SpO₂ 94–98%. PaCO₂ 4.5–5 kPa (normocapnia only — prophylactic hyperventilation causes cerebral ischaemia).
Glucose 4–8 mmol/L. Temperature 36–37°C. Seizure control (levetiracetam prophylaxis in TBI). Avoid hypotonic fluids.
Osmotherapy — Choose One
Mannitol 20%: 0.25–0.5 g/kg IV (= 1.25–2.5 mL/kg 20% mannitol) over 15–20 min. Target serum osmolality <320 mOsm/kg. Repeat q4–6h.
3% NaCl: 2–5 mL/kg IV over 10–20 min — equally effective, maintains intravascular volume (preferred if hypotensive). Target Na⁺ 145–155 mmol/L.
Common Causes in Children
TBI (most common), bacterial meningitis, viral encephalitis, DKA cerebral oedema, brain tumour, hydrocephalus, VP shunt failure, hypertensive encephalopathy, status epilepticus.
VP shunt failure: any change in headache pattern in shunted child = shunt failure until proven otherwise. Urgent neurosurgical review. Shunt series X-rays + CT head.

UTI in Children (NICE NG224)

Clean catch MSU · Dipstick interpretation · Cefalexin · USS criteria · DMSA scan

NICE NG224 2022
📋 Diagnosis, Treatment & Imaging
Urine Collection
Clean catch MSU preferred. Suprapubic aspiration (SPA) if clean catch not possible. Catheter specimen if SPA failed. Bag urine: high false positive rate — only use for dipstick.
Dipstick Interpretation
Nitrite positive: Probable UTI — treat empirically, send MSU for culture confirmation
Nitrite negative + leucocytes positive: Possible UTI — send MSU and consider empirical treatment in unwell child
Both negative: UTI unlikely — do not treat empirically unless clinically very unwell
Empirical Antibiotic Treatment
Lower UTI (≥3 months, well, afebrile): Trimethoprim 4 mg/kg BD (max 200 mg) × 3 days OR cefalexin 12.5 mg/kg QDS × 3 days
Pyelonephritis (febrile, systemically unwell): Cefalexin 12.5 mg/kg QDS × 7–10 days oral OR cefotaxime 50 mg/kg q8h IV
<3 months: IV antibiotics always — cefotaxime 50 mg/kg q8h + amoxicillin 50 mg/kg q6h. Admit.
Imaging (NICE NG224)
Urgent USS (<6h): <6 months, atypical infection (non-E.coli, serious illness, raised creatinine), poor response to antibiotics at 48h
USS within 6 weeks: First febrile UTI ≥6 months if good response. Recurrent UTI at any age.
DMSA (static renal scan at 4–6 months post-infection): Atypical or recurrent UTI — detects renal scarring. VUR on MAG3 if recurrent/abnormal DMSA.

Septic Arthritis & Osteomyelitis

Kocher criteria · Flucloxacillin · Surgical washout · 4–6 weeks antibiotics

BOA · BOAST · RCPCH
📋 Kocher Criteria & Management
Kocher Criteria — Septic Arthritis vs Transient Synovitis (Hip)
1. Fever >38.5°C | 2. Non-weight-bearing | 3. ESR >40 mm/h | 4. WCC >12 × 10⁹/L | 5. CRP >20 mg/L (Caird et al.)
0 criteria: <0.2% probability septic arthritis. 1 criterion: 3%. 2 criteria: 40%. 3 criteria: 93.1%. 4–5 criteria: 99.6% → theatre for washout.
Investigation
FBC, CRP, ESR, blood cultures (before antibiotics if possible but DO NOT delay treatment). Plain X-ray (often normal early — periosteal reaction 7–14 days). USS hip: effusion.
MRI: gold standard — shows bone and soft tissue changes early. Bone scan if MRI unavailable or multi-focal disease suspected.
Antibiotic Treatment
Organism: Staph aureus (most common all ages). Strep (any age). Kingella kingae (<5y). GBS (neonates). HiB (unvaccinated).
Flucloxacillin 50 mg/kg IV q6h (max 2g/dose) × 2 weeks IV then oral × 4 weeks total
MRSA risk factors: vancomycin 15 mg/kg IV q6h (max 1g/dose) target trough 10–15 mg/L
MSSA confirmed: can step down to oral flucloxacillin 25 mg/kg QDS when clinically improving + CRP falling
Surgical Management
Septic arthritis: Arthrotomy or arthroscopic washout + irrigation. Urgent — within hours. Hip: open washout to preserve femoral head blood supply.
Osteomyelitis: Most managed medically. Surgery if: subperiosteal abscess, no response to antibiotics 48h, bone necrosis, chronic osteomyelitis (sequestrum).

Paediatric DKA (BSPED 2021)

BSPED 2021 · Cerebral oedema prevention · 48h fluid replacement · No bolus unless shocked · Insulin 0.05–0.1 u/kg/h

BSPED 2021 · ISPAD 2022
🚨

BSPED 2021 KEY CHANGES: Spread fluid replacement over 48h (not 24h). No fluid bolus unless shocked (BP severely low, GCS ≤11). Slower insulin start (0.05 u/kg/h). Goal: prevent cerebral oedema — the main cause of death in paediatric DKA.

📋 DKA Severity & Protocol

Mild (pH 7.2–7.29)

Alert, tolerating fluid. Oral rehydration may suffice. Insulin SC if established on pump.

Moderate (pH 7.1–7.19)

IV fluids. Insulin infusion 0.05–0.1 u/kg/h. Hourly neurological obs.

Severe (pH <7.1)

PICU consideration. Strict fluid protocol. Glasgow Coma Score monitoring. Consider intubation.

Fluid Management (BSPED 2021)
Shock resuscitation (ONLY if: BP severely low, poor perfusion, GCS ≤11): 10 mL/kg NaCl 0.9% IV over 15–30 min. Repeat once only if needed. Do NOT give fluid bolus routinely.
48h rehydration: Calculate deficit (mild 5%, moderate 7%, severe 10% body weight) + maintenance. Replace over 48h (not 24h) as 0.9% NaCl. Use BSPED calculator.
Add 5% dextrose when BG <14 mmol/L. Add KCl to bags from the start (assuming urine output confirmed).
Insulin Infusion
Start insulin 1 hour after fluids begin (not simultaneously). Rate: 0.05 units/kg/h (mild-moderate) or 0.1 units/kg/h (severe). Do not exceed 0.1 u/kg/h.
Target BG fall: 3–5 mmol/L/h. Never stop insulin while ketones positive. Reduce rate rather than stopping if BG falling fast.
Ketones must be monitored — beta-hydroxybutyrate. Target: <0.5 mmol/L before converting to SC insulin.
Cerebral Oedema — Recognition & Treatment
Risk factors: very young age, new diagnosis T1DM, severe acidosis, low PCO₂, high urea, bicarbonate treatment, rapid fluid administration, hyponatraemia.
Signs: Headache, behaviour change, GCS fall, specific neurological signs, bradycardia, papilloedema — onset typically 4–12h after treatment starts.
Treatment: Mannitol 20% 0.5–1 g/kg IV over 10–15 min OR 3% NaCl 2.5–5 mL/kg over 15 min. Reduce fluid rate. Intubate if GCS deteriorating. PICU immediately.

Paediatric Hypertensive Emergency

SBP >99th centile + 5 mmHg · End-organ damage · Labetalol · Amlodipine · Secondary causes

NICE NG136 · ESH 2022 · AAP 2017

Unlike adults, hypertension in children is nearly always SECONDARY. Always look for an underlying cause. Lower BP gradually — reduce MAP by no more than 25% in first 6–8h. Rapid lowering causes ischaemia.

📋 Definition, Causes & Management
Definition (Age-Specific)
Hypertensive urgency: BP >99th centile + 5 mmHg for age/sex/height. No end-organ damage.
Hypertensive emergency: Same BP threshold + end-organ damage (encephalopathy, seizures, retinal changes, acute kidney injury, cardiac failure, haemorrhage).
Approximate thresholds: <1y: >100/70 | 1–5y: >110/74 | 6–12y: >120/80 | 13–17y: >130/85 mmHg
Secondary Causes (Always Investigate)
Renal (most common 70–80%): Renal artery stenosis, renal parenchymal disease (GN, reflux nephropathy, PKD, HUS)
Cardiovascular: Coarctation of aorta (check femoral pulses and 4-limb BPs)
Endocrine: Phaeochromocytoma, Cushing's, hyperaldosteronism, hyperthyroidism, CAH
Drugs: Stimulants (amphetamines, cocaine), steroids, ciclosporin, NSAIDs, OCP
Other: Raised ICP, pain, anxiety, white coat hypertension (confirm with repeat readings)
Investigations
U&E, creatinine, urine dipstick + MC&S, urine protein:creatinine ratio, FBC, calcium, TFTs, plasma renin/aldosterone. Renal USS. Echocardiogram (LVH). Fundoscopy.
Plasma/urine catecholamines if phaeochromocytoma suspected. 4-limb BPs if coarctation suspected.
Emergency Treatment (End-Organ Damage)
Target: Reduce MAP by max 25% in first 6–8h, then normalise over 24–48h. Too rapid lowering = ischaemia.
Labetalol IV: 0.2–1 mg/kg/h infusion (max 3 mg/kg/h). Bolus 0.2–0.5 mg/kg IV over 2 min. Avoid in asthma, cardiac failure, bradycardia.
Sodium nitroprusside: 0.5–8 mcg/kg/min — rapid onset/offset, PICU only, cyanide toxicity risk >72h.
Hydralazine 0.1–0.5 mg/kg IV (max 20 mg) bolus q4–6h — good for renal hypertension.
Hypertensive encephalopathy: treat seizures (lorazepam), manage ICP, urgent nephrology/PICU.
Oral Agents (Urgency Without End-Organ Damage)
Amlodipine 0.1–0.3 mg/kg OD (max 5 mg) — calcium channel blocker, well tolerated
Nifedipine modified-release 0.25–0.5 mg/kg BD (max 3 mg/kg/day). Avoid immediate-release (rapid drop).
Refer to paediatric nephrology for all children with confirmed hypertension requiring treatment.

Paediatric Hyperosmolar Hyperglycaemic State (HHS)

Adolescent T2DM · Glucose >33 mmol/L · Osmolality >320 · Very gradual fluid replacement · Thrombosis risk

BSPED 2022 · ISPAD 2022
🚨

Paediatric HHS is distinct from adult HHS and from DKA. Mortality and morbidity are HIGH. May overlap with DKA (mixed picture). Extreme dehydration (10–15 L deficit). Replace fluid VERY slowly over 48–72h. Thrombosis is a major complication.

📋 Diagnosis & Management
Diagnostic Criteria (BSPED 2022)
Glucose >33 mmol/L | Osmolality >320 mOsm/kg | Minimal or absent ketonaemia (beta-OH butyrate <3 mmol/L) | No or mild acidosis (pH >7.25, HCO₃ >15)
Calculated osmolality: 2(Na + K) + glucose + urea. Corrected sodium: Na + 2 × ((glucose − 5.5) / 5.5).
Context: obese adolescent, T2DM (often new diagnosis), often precipitated by infection, vomiting, reduced fluid intake over days-weeks.
Fluid Replacement — The Key Difference From DKA
Replace deficit over 48–72h (NOT 24h or 48h as in DKA). Aim to reduce osmolality by no more than 3–5 mOsm/kg/h.
0.9% NaCl throughout initial replacement — do NOT switch to hypotonic fluids early. Risk: cerebral oedema from too-rapid osmolality fall.
If shocked: 10 mL/kg 0.9% NaCl bolus (cautious — most are profoundly dehydrated but not shocked).
Maintenance + deficit. Monitor osmolality and corrected Na⁺ hourly. Aim glucose fall ≤5 mmol/L/h.
Insulin
Do NOT start insulin immediately. Fluids alone often bring glucose down safely.
Start insulin (0.05 units/kg/h) ONLY if: glucose not falling with fluids alone, or significant ketosis (mixed HHS/DKA). Add dextrose when glucose <14 mmol/L.
Thromboprophylaxis
High thrombosis risk: hyperviscous blood + immobility + dehydration + adolescent obesity. LMWH: enoxaparin 1 mg/kg SC BD (prophylactic) while in hospital.
DVT/PE: treat dose enoxaparin 1 mg/kg SC BD. Consider catheter-directed thrombolysis for major PE.
Monitoring
Hourly: BG, urine output, neurological obs. 2-hourly: VBG (osmolality, electrolytes, ketones). Cardiac monitoring.
Cerebral oedema: headache, behaviour change, GCS fall → mannitol 0.5 g/kg IV / 3% NaCl 3 mL/kg IV. Reduce fluid rate.
PICU for all severe HHS. Endocrinology/paediatric diabetes team urgent input.

Sickle Cell Crisis in Children

Vaso-occlusive crisis · Acute chest syndrome · Splenic sequestration · Stroke · Exchange transfusion

BSH 2021 · NICE NG143 · RCPCH
🚨

Acute chest syndrome (ACS) is the leading cause of death in sickle cell disease. Fever + respiratory symptoms + new CXR infiltrate = ACS until proven otherwise. Transfuse early — do not wait for deterioration.

📋 Vaso-Occlusive Crisis (Painful Crisis)
Management
Pain assessment within 30 min of arrival. Target: effective analgesia within 60 min. Use NRS or FLACC.
Mild-moderate: Ibuprofen 10 mg/kg + paracetamol 15 mg/kg regular. Oral morphine 0.3–0.5 mg/kg q4h if needed.
Severe: IV morphine 0.05–0.1 mg/kg bolus q20 min PRN until controlled, then PCA or regular dosing. Do not undertreat — these children know their pain.
IV fluids: 0.9% NaCl or Hartmann's at 1–1.5× maintenance. Incentive spirometry (prevents ACS). Warmth. Avoid triggers: cold, dehydration, infection, hypoxia.
Admit if: IV analgesia needed, fever, respiratory symptoms, neurological symptoms, splenic enlargement, Hb fall >20 g/L from baseline, priapism >4h.
🫁 Acute Chest Syndrome (ACS)
Diagnosis
New infiltrate on CXR + one of: fever, cough, tachypnoea, wheeze, chest pain, hypoxia (SpO₂ <95% or >3% from baseline).
Cause: fat embolism, infection (pneumonia — atypical organisms common), pulmonary infarction, hypoventilation. Often presents as pain crisis first.
Treatment
O₂ to maintain SpO₂ ≥95%. IV analgesia (avoid over-sedation). Incentive spirometry.
Antibiotics: Co-amoxiclav 30 mg/kg q8h IV + clarithromycin 7.5 mg/kg BD (atypical cover — Mycoplasma common)
Simple transfusion: Hb <90 g/L or rapidly falling → 5 mL/kg pRBC (sickle-negative, leucodepleted, extended matched). Target Hb 90–100 g/L.
Exchange transfusion: Severe ACS (SpO₂ <90% despite O₂, rapid deterioration, multi-lobar) → automated red cell exchange. Contact haematology immediately. Target HbS <30%.
PICU if: mechanical ventilation needed, SpO₂ deteriorating despite treatment.
🧠 Stroke & Splenic Sequestration
Stroke (Overt Ischaemic)
Sudden focal neurological deficit, seizures, altered consciousness. Do NOT give thrombolytics — ischaemia due to sickling, not clot.
Emergency exchange transfusion immediately — target HbS <30%. MRI/CT urgently but DO NOT delay exchange for imaging if diagnosis clear. Haematology NOW.
TCD (transcranial Doppler) screening programme — velocity >200 cm/s predicts stroke risk → chronic transfusion programme.
Acute Splenic Sequestration
Sudden massive splenomegaly + acute anaemia (Hb falls ≥20 g/L from baseline) + thrombocytopenia. Hypovolaemic shock. Age typically 3 months–5 years (before autosplenectomy).
10 mL/kg pRBC immediately (sickle-negative). Do not over-transfuse — sequestered blood re-enters circulation on recovery → hyperviscosity. Target Hb 70–80 g/L.
Recurrence risk 50%. Elective splenectomy after second episode. Vaccinations before splenectomy: PCV, MenACWY, HiB, influenza.
Priapism
>4 hours = emergency. Analgesia. IV fluids. Oral pseudoephedrine 1 mg/kg (unlicensed). Urology urgently — aspiration + irrigation of corpus cavernosum if no resolution by 4h.
Exchange transfusion if surgical management fails. Erectile dysfunction risk increases with duration — treat aggressively.

Neonatal Jaundice (NICE NG98)

NICE NG98 · Phototherapy thresholds by gestation · IVIg for haemolytic · Exchange transfusion

NICE NG98 2016 · BAPM · RCPCH
📋 Recognition, Thresholds & Treatment
Assessment
Pathological if: jaundice within 24h of birth (always urgent), jaundice in unwell baby, rising SBR despite phototherapy, direct bilirubin >25 mmol/L (conjugated — liver disease).
Serum bilirubin (SBR) hourly if rising rapidly. Use NICE phototherapy/exchange transfusion threshold charts for gestational age.
Phototherapy
Intensive phototherapy: irradiance ≥30 µW/cm²/nm. Maximum skin exposure. Continuous (remove for feeds only).
Threshold: use NICE NG98 nomogram by postnatal age in hours and gestation. Lower threshold for haemolytic disease.
Recheck SBR 4–6h after starting. If rising despite phototherapy → IVIg.
IVIg (Haemolytic Disease — Rh/ABO)
IVIg 500 mg/kg IV over 2–4h — if SBR rising despite intensive phototherapy. Reduces haemolysis and exchange transfusion requirement.
Repeat after 12h if bilirubin still rising rapidly.
Exchange Transfusion
Indicated when SBR above exchange threshold on NICE chart, or encephalopathy developing (acute bilirubin encephalopathy: hypotonia → hypertonia, arched back, high-pitched cry).
Double-volume exchange: 160–180 mL/kg. Via UVC. Irradiated, CMV-negative, crossmatched blood. Paediatric haematologist input.

📋 Classification, Features & Antibiotics
Classification
Early-Onset Sepsis (EOS): <72h of age. Organisms: GBS, E. coli, Listeria, other gram-negatives. Risk: maternal GBS, PPROM, maternal fever, prematurity, invasive procedure.
Late-Onset Sepsis (LOS): >72h of age. Organisms: CoNS (NICU), Staph aureus, gram-negatives, Candida. Risk: prematurity, lines, prolonged NICU stay.
Clinical Features
Temperature instability (fever OR hypothermia). Respiratory distress. Apnoeas. Poor feeding. Lethargy/hypotonia. Mottled/pale skin. Bulging fontanelle. Seizures. Shock (late).
Empirical Antibiotics — EOS
Benzylpenicillin 50 mg/kg IV q12h (term) or q6h (meningitis dose) + Gentamicin 5 mg/kg OD IV
Meningitis suspected (LP: high WCC, low glucose): add cefotaxime and increase benzylpenicillin to 50 mg/kg q6h
Empirical Antibiotics — LOS (NICU)
Line-associated / CoNS suspected: Vancomycin 15 mg/kg q6–12h IV (adjust by levels) + gentamicin 5 mg/kg OD
Gram-negative sepsis risk: pip-tazo or meropenem (local policy). Antifungal (fluconazole/amphotericin) if Candida risk.
Investigation (NICE NG195)
Blood culture. CRP at presentation and 18–24h. FBC. CXR if respiratory. LP if meningitis suspected and baby stable. Urine MC&S (catheter/SPA — not bag).
NICE NG195 2021: CRP <10 at 18–24h in well baby = low risk, review antibiotics at 36h.

Neonatal Respiratory Distress Syndrome (NRDS)

Surfactant deficiency · CPAP · Calfactant/Poractant · Caffeine · INSURE technique

BAPM · BTS · ESPNIC
📋 Features & Management
Features
Preterm neonates (inversely proportional to gestational age: nearly universal <28 weeks). Surfactant deficiency → alveolar collapse → ground-glass opacification on CXR → air bronchograms.
Tachypnoea, recession, grunting (auto-PEEP), nasal flaring. Onset at birth or within 4h. Antenatal steroids (dexamethasone/betamethasone) dramatically reduce severity.
CPAP — First-Line Respiratory Support
nCPAP 5–8 cmH₂O (Infant Flow or NCPAP). Maintains lung volume. FiO₂ titrated to SpO₂ 91–95% (<34 weeks) or 93–97% (>34 weeks).
CPAP reduces need for intubation and surfactant in mild-moderate NRDS. Continue CPAP after surfactant (INSURE technique).
Surfactant Therapy
Poractant alfa (Curosurf): 100–200 mg/kg IT via ET tube. Second dose 100 mg/kg if still intubated and FiO₂ >0.3 after 6–12h.
INSURE technique: INtubate-SURfactant-Extubate — brief intubation for surfactant, then immediate extubation to CPAP. Reduces ventilator-associated lung injury.
LISA (Less Invasive Surfactant Administration): surfactant via thin catheter while baby breathes on CPAP — preferred in experienced centres.
Caffeine
Caffeine citrate loading: 20 mg/kg IV/oralmaintenance 5–10 mg/kg OD. All preterm <34 weeks. Reduces apnoea, BPD, cerebral palsy, improves survival. Continue until 34+ weeks.

BAPM · BAPS · ESPGHAN
📋 Bell Staging & Management
Bell Staging (Modified)
Stage I (Suspected): Temperature instability, apnoea, abdominal distension, blood in stool. Normal/non-specific X-ray. Treat as NEC.
Stage II (Proven): Above + absent bowel sounds, tenderness. Pneumatosis intestinalis (intramural gas — pathognomonic) or portal venous gas on X-ray.
Stage III (Advanced): Stage II + shock, DIC, peritonitis. Free air on X-ray = perforation = surgery.
Medical Management (Stages I–II)
NBM: Stop all enteral feeds immediately. NG tube free drainage. IV nutrition (TPN) via central line.
Antibiotics: Pip-tazo 90 mg/kg q8h IV + metronidazole 15 mg/kg q12h IV. Duration 7–14 days. Discuss with microbiology.
Supportive: IV fluids, vasopressors if shocked, treat DIC (FFP, platelet transfusion). Serial abdominal X-rays 6–12h. Bloods 12-hourly.
Surgical Management (Stage III / Perforation)
Absolute indications: free air (perforation), clinical deterioration despite medical management, palpable abdominal mass.
Options: laparotomy + resection of necrotic bowel + stoma formation. Or peritoneal drainage (VLBW unstable neonates) as bridge to definitive surgery.

Haemolytic Disease of the Newborn

Rh incompatibility · Anti-D · IVIg · Phototherapy · Exchange transfusion

NICE NG25 · BCSH · RCOG
📋 Pathophysiology & Management
Types & Causes
Rh incompatibility (anti-D): Rh-negative mother, Rh-positive baby. Sensitisation in previous pregnancy. Increasingly prevented by anti-D prophylaxis
ABO incompatibility: O mother + A or B baby. Milder than Rh. Most common cause of significant neonatal jaundice in UK
Other red cell antibodies: anti-Kell, anti-c, anti-E — may cause severe disease
Features: early jaundice (<24h), anaemia, hydrops fetalis (severe — ascites, pleural/pericardial effusions, oedema)
Prevention
Anti-D immunoglobulin 1500 IU IM to Rh-negative mother at 28 weeks, 34 weeks, and within 72h of delivery, sensitising event (amniocentesis, antepartum haemorrhage, miscarriage)
Kleihauer test: quantifies feto-maternal haemorrhage — guides anti-D dose post-delivery
Neonatal Treatment
Intensive phototherapy for hyperbilirubinaemia (per NICE NG98 bilirubin thresholds — lower in haemolytic disease)
IVIg 500 mg/kg IV over 2–4h: reduces haemolysis and exchange transfusion requirement. Give if SBR rising despite phototherapy
Exchange transfusion: double-volume (160–180 mL/kg) via UVC. Use crossmatched blood (irradiated, CMV-negative). Removes antibodies + bilirubin + sensitised RBCs
Top-up transfusion: for progressive anaemia after acute phase. Intrauterine transfusion for severe cases (diagnosed antenatally)

Neonatal Abstinence Syndrome (NAS)

Finnegan score · Morphine / methadone weaning · Supportive care · Non-pharmacological first

BAPM 2020 · AAP 2012 · NICE
📋 Recognition, Scoring & Management
Background & Timing
Occurs in neonates born to mothers dependent on opioids (prescribed or illicit), benzodiazepines, SSRIs, alcohol, stimulants.
Onset timing: Heroin/short-acting opioids: 24–48h. Methadone: 36–72h (may be up to 5 days). SSRIs: 24–48h. Benzodiazepines: up to 5–7 days.
Symptoms: high-pitched cry, irritability, poor feeding, vomiting, diarrhoea, hypertonicity, tremors, sweating, sneezing, yawning, seizures (severe).
Finnegan Neonatal Abstinence Score (Modified)
Score 21 items across: CNS (crying, sleep, Moro, tremors, tone, seizures), metabolic (fever, sweating, yawning, sneezing, nasal stuffiness), GI (poor feeding, regurgitation, loose stools), skin (excoriation).
Score every 3–4h for first 5 days. Score <8: no treatment. Score 8–12: increase non-pharmacological. Score >12 or ≥8 on 3 consecutive scores: pharmacological treatment.
Non-Pharmacological (Always First-Line)
Rooming-in with mother (reduces pharmacological treatment need by 50%). Skin-to-skin contact. Swaddling. Low stimulation environment (dim lights, minimal noise).
Breastfeeding encouraged if mother on stable methadone/buprenorphine and no other contraindication (HIV, illicit drug use). Small frequent feeds.
Pharmacological Treatment
Morphine oral solution 0.04–0.08 mg/kg per dose q3–4h — first-line for opioid NAS. Dose titrated to Finnegan score. BAPM 2020.
Increase dose by 10% if scores remain high. Wean by 10% every 24–48h once scores consistently <8 for 48h.
Methadone alternative: 0.05–0.1 mg/kg q12h — longer half-life, easier weaning schedule for methadone-exposed infants.
Adjunct (non-opioid NAS or refractory): Phenobarbitone 5–8 mg/kg/day divided BD. Clonidine 0.5–1 mcg/kg q4–8h (monitor BP/HR).
Monitoring & Discharge
Monitor minimum 5–7 days for opioid NAS (longer for methadone). NAS seizures: phenobarbitone loading 20 mg/kg IV. Hypoglycaemia monitoring (glucose every 4–6h).
Safeguarding assessment mandatory. MDT: neonatology, midwifery, social care, drug liaison team. Written weaning plan on discharge.

Intussusception

Peak 6–18 months · Redcurrant jelly stools · USS diagnosis · Air enema reduction · Surgery if failed

BAPS · RCR · RCPCH

Classic triad (colicky pain + vomiting + redcurrant jelly stools) present in only 40%. High index of suspicion in any infant with paroxysmal screaming, pale episodes, or unexplained altered consciousness. USS is diagnostic.

📋 Features, Diagnosis & Management
Clinical Features
Peak age 6–18 months (80%). Ileocolic junction most common. Paroxysmal colicky abdominal pain → infant draws knees up, becomes pale and lethargic between episodes.
Vomiting (initially non-bilious, then bilious as obstruction worsens). Redcurrant jelly stool (blood + mucus) — late sign. Sausage-shaped abdominal mass (right upper quadrant → right lower quadrant).
Late: abdominal distension, peritonitis, shock. Pathological lead point (<2y rare, >5y consider — Meckel's, polyp, lymphoma).
Diagnosis
USS: "Doughnut" or "target" sign (concentric rings of bowel). Sensitivity 98%, specificity 88%. First-line investigation.
AXR: dilated small bowel loops, absent right iliac fossa gas pattern, soft tissue mass. Useful if USS unavailable or perforation suspected (free air).
Management
IV access. IV fluids. Analgesia (morphine 0.1 mg/kg IV). NBM. NG tube if vomiting/distended. Blood crossmatch.
Air enema reduction (radiological): Success rate 70–90% in uncomplicated cases. Done under fluoroscopy or USS guidance. Risks: perforation (1–3%). Sedation required. Paediatric surgeon must be available immediately.
Contraindications to air enema: Peritonitis, perforation (free air on AXR), haemodynamic instability, long symptom duration (>48h relative).
Surgery: Failed enema, perforation, peritonitis, or suspected pathological lead point. Laparoscopic or open reduction ± resection if ischaemic bowel.

3–6 weeks · Non-bilious projectile vomiting · Hypochloraemic alkalosis · Ramstedt's pyloromyotomy

BAPS · RCPCH

Pyloric stenosis is NOT a surgical emergency — correct the electrolyte abnormality FIRST. Operating on an uncorrected hypochloraemic alkalosis = anaesthetic risk. Target: Na >130, K >3.0, HCO₃ <30, Cl >90 before theatre.

📋 Diagnosis & Management
Clinical Features
Age 3–6 weeks (range 2–8 weeks). Male:Female 4:1. First-born male. Positive family history (maternal > paternal). Increasing frequency in UK.
Non-bilious projectile vomiting after feeds — force may increase. Hungry infant who wants to feed immediately after vomiting. Progressive weight loss, dehydration.
Olive-shaped mass palpable in right upper quadrant in 50–80% (best after vomiting, in relaxed, warm infant). Visible peristaltic waves across abdomen.
Metabolic Derangement
Hypochloraemic hypokalaemic metabolic alkalosis — from repeated vomiting of HCl. Serum Cl⁻ ↓, K⁺ ↓, Na⁺ ↓, pH ↑, HCO₃ ↑.
Paradoxical aciduria: despite alkalosis, kidney excretes acid urine to conserve Na⁺ (H⁺ secreted instead of K⁺).
Diagnosis
USS: Pyloric muscle thickness >4 mm, pyloric channel length >17 mm. Sensitivity >95%. First-line.
Barium meal (historical) — "string sign" on contrast. Only if USS equivocal.
Pre-operative Resuscitation
0.9% NaCl + KCl (20–40 mmol/L) IV. Do NOT use dextrose alone. Correct electrolytes before surgery — may take 24–48h.
Target before GA: Na⁺ >130, K⁺ >3.0, HCO₃⁻ <30, Cl⁻ >90 mmol/L. NG tube free drainage.
Surgery — Ramstedt's Pyloromyotomy
Laparoscopic (preferred) or open. Longitudinal incision through pyloric muscle down to mucosa — preserving mucosa integrity. Cure rate >99%.
Feed 4–6h post-op. Minor vomiting normal for 24–48h. Discharge 24–48h post-surgery.

Meckel's Diverticulum

Rule of 2s · Painless rectal bleeding · Tc-99m pertechnetate scan · Laparoscopic resection

BAPS · RCPCH
📋 Rule of 2s, Features & Management
Rule of 2s
2% of the population | 2 feet from ileocaecal valve | 2 inches long | 2 types of ectopic tissue (gastric most common, pancreatic) | 2:1 male predominance | 2 years most common age for presentation
Clinical Presentations
Painless rectal bleeding (most common in children): Bright red or dark red blood PR. Gastric mucosa in diverticulum → acid → ulceration → bleeding. May be massive.
Obstruction: Intussusception (Meckel's as lead point), volvulus around fibrous band.
Meckel's diverticulitis: Clinically identical to appendicitis. Consider if laparoscopy negative appendix.
Diagnosis
Tc-99m pertechnetate (Meckel's) scan: 85% sensitivity for gastric mucosa. False negative if no gastric mucosa. Best in children.
Capsule endoscopy / CT angiography (active bleeding). Laparoscopy (diagnostic + therapeutic). USS may show.
Management
Active bleeding: IV access, crossmatch, transfuse. Stabilise. Then Meckel's scan or laparoscopy.
Surgery: Laparoscopic diverticulectomy or small bowel resection (if wide base or palpable ectopic tissue). Symptomatic Meckel's always resected. Incidental finding: resect if ectopic mucosa suspected or in child <2y.

Paediatric Appendicitis

PAS score · USS / MRI preferred · Co-amoxiclav · Laparoscopic appendicectomy

BAPS · NICE · RCPCH
📋 PAS Score & Management
Paediatric Appendicitis Score (PAS)
Tenderness RIF: 2 points | Anorexia: 1 | Nausea/vomiting: 1 | Migration of pain to RIF: 1 | Fever >38°C: 1 | WBC >10×10⁹: 1 | PMN >75%: 1 | Cough tenderness/rebound RIF: 2 | Total: 10 points
≤3: Low risk — discharge with advice. 4–6: Intermediate — observe 24h ± USS. ≥7: High risk — surgical review ± imaging.
Clinical Features
Pain: periumbilical → RIF (classical migration). Anorexia. Vomiting. Fever (usually low-grade initially).
RIF tenderness, guarding. Rovsing's sign, psoas sign. Young children: atypical presentation common — peritonitis occurs earlier (thin omentum).
Perforated appendicitis: diffuse peritonitis, high fever, very unwell. More common in children (<24h history to perforation in young children).
Investigations
FBC (WBC/neutrophilia), CRP, CXR (exclude pneumonia mimicking appendicitis). Urine dipstick (sterile pyuria in 20% appendicitis — don't be misled).
USS first-line imaging (avoids radiation): inflamed appendix >6mm, non-compressible, periappendiceal fat stranding. Sensitivity 70–94% (operator dependent).
MRI if USS non-diagnostic and high clinical suspicion (no radiation). CT if MRI unavailable and clinical urgency.
Management
IV access. Analgesia early (does NOT mask signs — evidence clear). NBM. IV fluids. Co-amoxiclav 30 mg/kg q8h IV (or single pre-op dose in uncomplicated).
Laparoscopic appendicectomy: gold standard. Safe in children. Perforated: thorough peritoneal lavage. Post-op antibiotics × 3–5 days if perforated.
Non-operative management (antibiotics alone): emerging evidence in uncomplicated appendicitis. High recurrence rate (30–40% at 5y). Surgical decision-making.

Testicular Torsion

Surgical emergency · 6-hour viability window · Absent cremasteric reflex · Manual detorsion · Orchidopexy

BAUS · EAU · RCPCH
🚨

Testicular torsion is a surgical emergency. Viability: >95% if operated within 6h, ~50% at 12h, <10% at 24h. Do NOT wait for USS if clinical suspicion is high. Normal USS does NOT exclude torsion if clinically suspected — go directly to theatre.

📋 Recognition & Management
Clinical Features
Bimodal: neonates (extravaginal torsion at birth) and puberty (peak 12–18 years, intravaginal torsion — bell-clapper deformity).
Sudden onset severe unilateral scrotal pain. Nausea and vomiting. High-riding testis. Transverse lie (horizontal lie — pathognomonic).
Absent cremasteric reflex: most reliable sign (sensitivity 99%) — stroking inner thigh should elevate testis. Absent in torsion.
Differential: epididymo-orchitis (gradual, urinary symptoms, tender epididymis), torted hydatid of Morgagni (blue dot sign — tender nodule at upper pole), hernia, trauma, tumour.
Investigation
Colour Doppler USS: Absent or reduced blood flow — sensitivity 88–100%. Do NOT delay surgery if clinical diagnosis clear. Normal USS does NOT exclude torsion.
Send routine bloods + group and save. Analgesia: morphine 0.1 mg/kg IV. NBM immediately.
Management
Immediate urology/paediatric surgery referral. Mark scrotum side. NBM. IV access.
Manual detorsion ("open book"): Rotate testis outward (lateral) — as opening a book. Medial torsion is most common (twist inward). Relief of pain confirms success. Temporary only — surgery still required.
Surgical exploration: Scrotal incision. Detorsion and assess viability. Viable → orchidopexy (3-point fixation to tunica vaginalis). Infarcted → orchidectomy. Contralateral orchidopexy always performed.

Foreign Body Ingestion

Button battery = emergency (<2h) · Coin · Magnets · Oesophageal vs gastric · Endoscopy criteria

BSG · ESPGHAN · BAPS 2021
🚨

BUTTON BATTERY in oesophagus = endoscopic emergency within 2 hours. Liquefactive necrosis begins in <2h. Honey 10 mL q10 min (if >1y, alert, no airway compromise) while arranging emergency endoscopy — reduces mucosal injury.

📋 Assessment by Object Type
Button Battery (Lithium 20mm disc)
Oesophagus: Emergency endoscopy within 2h regardless of symptoms. Double ring sign on X-ray (distinguishes from coin). Honey 10 mL q10 min if >1 year old, alert, no respiratory compromise.
Stomach/beyond (asymptomatic): If >20 mm AND <5 years → remove. If <20 mm or >5 years → observe, repeat AXR in 4 days if not passed. Remove if symptomatic at any point.
Post-removal: oesophageal injury common. NGT, PPI (omeprazole 1 mg/kg OD), barium swallow at 3–4 weeks.
Coins & Blunt Objects
Oesophagus: Symptoms (drooling, dysphagia, vomiting) → endoscopy within 24h. Asymptomatic → endoscopy within 24h if upper oesophagus, can await 24h if lower.
Stomach/beyond: Most pass spontaneously. Coins <23 mm usually pass within 4–6 weeks. Observe, repeat AXR in 4 weeks. No dietary restriction needed.
Endoscopy required: persistent oesophageal location >24h, sharp objects anywhere in GI tract, symptomatic at any location.
Multiple Magnets / Magnet + Metal Object
Two or more magnets, or magnet + metal: Can attract across bowel loops → pressure necrosis, perforation, fistula. Remove urgently regardless of location.
Single magnet: usually safe to observe if asymptomatic and in stomach/bowel. AXR to confirm passage.
Sharp Objects (Needles, Pins, Bones)
Oesophagus: remove immediately. Stomach: remove within 24h (perforation risk in pylorus/duodenum). Beyond pylorus: 70–75% pass safely. Daily AXR. Remove if not progressing or symptomatic.
Symptoms at any stage → endoscopy/surgery immediately: Abdominal pain, fever, haematemesis, melaena, haemodynamic compromise.
Radiology
PA + lateral CXR (oesophageal vs tracheal), AXR. Button battery: double ring/halo sign on AP, step-off sign on lateral. Urgent if symptomatic. CT if perforation suspected.

Non-Accidental Injury (NAI) & Child Safeguarding

NICE NG76 · Recognition · Section 47 · Skeletal survey · Documentation

NICE NG76 2017 · Working Together 2023 · HM Government
🚨

Safeguarding is everyone's responsibility. Any clinician can — and must — refer to children's social care if they have concerns. You do not need parental consent to refer. If a child is in immediate danger, call police (999) immediately.

📋 Recognition & Red Flags
Features Raising Concern (NICE NG76)
Bruising: in non-mobile child (bruising before cruising), unusual sites (ears, neck, buttocks, back, face), shape of implement, multiple/different stages
Burns: contact burns with clear margins (cigarette, iron), immersion scalds (stockings/glove distribution), bilateral or symmetric
Fractures: in non-mobile infant, posterior rib fractures (highly specific for NAI), metaphyseal/corner fractures, multiple or different ages, spiral fractures in non-ambulant child
Head injury: subdural haematoma + retinal haemorrhages + encephalopathy = classic triad of abusive head trauma (shaken baby syndrome)
Behaviour: inconsistent history, delay in presentation, mechanism doesn't match injury, child discloses abuse, parental behaviour concerning
Action — Safeguarding Referral Process
Document everything: exact words used, body map, photography of injuries (with consent where possible), measurements. Time and date all entries
Consult designated/named safeguarding doctor immediately. Do NOT confront parents
Refer to Children's Social Care (Section 47 referral): if reasonable cause to suspect significant harm. Can be done without parental consent
Police: if immediate risk of serious harm or criminal offence. Joint agency response (MASH — Multi-Agency Safeguarding Hub)
Skeletal survey: all children <2 years with suspected physical abuse. Repeat films at 11–14 days (detects healing fractures). +CT head ± MRI

Paediatric Fractures

Salter-Harris · Toddler's fracture · Greenstick · Physeal injuries · Torus fracture

BOAST · BOA · RCPCH
📋 Fracture Patterns & Management
Fracture Types Unique to Children
Greenstick: incomplete fracture — cortex broken on tension side, intact on compression side. Treat with plaster ± manipulation
Torus (buckle) fracture: cortex buckles without complete break. Stable. Soft splint/wrist splint only. No manipulation needed. WBCTF trial: same outcomes with soft bandage as rigid cast
Toddler's fracture: undisplaced spiral fracture of distal tibia in ambulant child 9 months–3 years. Normal X-ray often. Bone scan/MRI if suspected. Above-knee POP 3 weeks
Plastic deformation: bone bends without fracture. Common in forearm. May need manipulation under GA
Salter-Harris Classification (Physeal/Growth Plate Fractures)
Type I: through physis only. X-ray may appear normal. Treat symptomatically
Type II: through physis + metaphysis (most common — 75%). Conservative if undisplaced
Type III: through physis + epiphysis. Intra-articular. May need ORIF
Type IV: through metaphysis + physis + epiphysis. Intra-articular. Usually requires ORIF
Type V: crush injury of physis. May appear normal acutely. Growth disturbance risk high
Mnemonic: SALTR — Same, Above, Lower, Through, Rammed (crushed)
NAI Alert Fractures
Posterior rib fractures (highly specific for squeezing/shaking). Metaphyseal corner fractures ("bucket-handle"). Multiple fractures at different stages. Spiral fractures in non-ambulant infants. Any fracture unexplained or inconsistent history

Paediatric Drowning & Choking

RCUK 2021 · 5 rescue breaths first · Cold water neuroprotection · Age-specific choking

RCUK 2021 · ILCOR
📋 Drowning & Choking Algorithms
Drowning — Paediatric Specific Points
5 rescue breaths first (as all paediatric arrest) before chest compressions — hypoxic arrest priority
Cold water drowning: "not dead until warm and dead." K⁺ <12 mmol/L = resuscitation should continue. Prolonged APLS/resuscitation warranted
C-spine: immobilise only if diving, watercraft injury, or clinical concern — routine immobilisation not recommended (RCUK 2021 revision)
Rewarming: warm IV fluids 39°C, warm humidified O₂, warm environment, bladder irrigation. ECMO in severe hypothermia
Choking — Infant (<1 year)
Mild obstruction: allow coughing. Do not intervene
Severe obstruction: face-down over forearm, head lower than chest. 5 back blows (heel of hand between shoulder blades)
Turn face-up on forearm. 5 chest thrusts (2 fingers on lower sternum, 1 finger-breadth below nipple line). NOT abdominal thrusts (liver injury risk)
Unconscious infant: start CPR (15:2). Look in mouth before each breath — only remove visible object
Choking — Child (>1 year)
Mild: encourage coughing. Severe: 5 back blows (lean forward, heel of hand between shoulder blades)
5 abdominal thrusts (Heimlich): stand behind, fist above umbilicus below xiphisternum, pull inward and upward. Scale force appropriately to child's size
Alternate 5+5. Call 999/crash team. If unconscious: CPR 15:2. Look in mouth each cycle
Advanced in ED: direct laryngoscopy + Magill forceps. RSI + fibreoptic if beyond cords. Surgical airway if complete obstruction

Self-Harm in Young People

NICE NG225 2022 · CAMHS · Psychosocial assessment · Risk assessment · MHA

NICE NG225 2022 · RCPCH

Every young person who presents with self-harm deserves a compassionate, non-judgmental psychosocial assessment. Self-harm is a signal of distress, not attention-seeking. Avoid conveying this attitude. All under-18s with self-harm must be seen by CAMHS before discharge.

📋 Assessment & Management
Immediate Medical Management
Treat physical injuries first. Paracetamol OD: 4-hour serum paracetamol level. N-acetylcysteine if above treatment line (Rumack-Matthew nomogram)
Lacerations: suture or steri-strip. Wound care and tetanus status
Ingestions: activated charcoal if within 1h, alert, airway protected. Identify substance(s). Toxicology advice
Psychosocial Assessment (NICE NG225)
All young people with self-harm must receive psychosocial assessment (not just psychiatric referral)
Assess: intent (was it planned? did they seek help?), method lethality, precipitating factors, mental state, support network, previous self-harm, suicidal ideation
Columbia Suicide Severity Rating Scale (C-SSRS) or equivalent — structured tool. Risk stratify: low/moderate/high
Always involve parents/carers (unless safeguarding concern). Assess family functioning
Disposition & Referral
All under-18s: CAMHS assessment before discharge. Do NOT discharge without mental health assessment
High risk / active suicidal ideation / no safe home environment: admit to paediatric ward under Section 2/3 MHA if needed
Safeguarding: always consider if young person is at risk from others as well as themselves. Refer to social care if needed
Crisis resources on discharge: written safety plan, crisis line numbers (PAPYRUS 0800 068 4141, Samaritans 116 123)

NICE NG69 2017 · MARSIPAN 2022 · Royal Colleges
📋 Medical Compromise & Management
Junior MARSIPAN — Medical Criteria for Admission (Children)
HR <40 bpm. BP <80/50 mmHg. SpO₂ <94%. Syncopal episodes. BMI <13 or >25% weight loss
Muscle weakness: unable to stand from squat without arm support (squat test). Electrolyte imbalance: K⁺ <3, PO₄ <0.5, Na⁺ <130, Mg <0.6
ECG: prolonged QTc (>450ms), arrhythmias, bradycardia. Hypoglycaemia
Emergency Management
Cardiac monitoring. IV fluids if haemodynamically compromised (cautiously — fluid overload risk in starved heart)
Refeeding syndrome prevention: start calories slowly (5–10 kcal/kg/day). Check and supplement: phosphate, potassium, magnesium, thiamine before refeeding
Thiamine 200 mg IV before any glucose (Wernicke's risk in severe malnutrition)
Nasogastric feeding: under specialist supervision. May require Mental Health Act/Mental Capacity Act in severe cases
Urgent CAMHS + paediatric joint review. Involve family. NICE NG69: family-based therapy is first-line treatment
Refeeding Syndrome — Watch For
Falls in phosphate, potassium, magnesium within 24–72h of starting nutrition → cardiac arrhythmias, respiratory failure, seizures, cardiac failure
Monitor electrolytes BD for first week of refeeding. Replace aggressively. Slow calorie increase if electrolytes fall

Behavioural Emergency & ADHD Crisis

De-escalation · Safeguarding · CAMHS · Medication · Mental Health Act (children)

NICE NG87 · RCEM · CAMHS
📋 Management
De-escalation (Always First-Line)
Calm environment: reduce noise/stimulation, quiet room, one consistent staff member communicating
Neutral, non-threatening body language. Validate feelings. Offer choices where possible. Avoid confrontation
Involve parents/carers — often most effective at calming child. Sensory tools for autism spectrum
Chemical Sedation (Last Resort — After De-escalation Failed)
Oral lorazepam 0.05 mg/kg (max 2 mg) — preferred first oral option if child cooperative
Oral/IM risperidone 0.5–1 mg (≥20 kg) — for psychotic features or known psychiatric history
IM midazolam 0.1–0.15 mg/kg (max 5 mg) — rapid sedation if IV not accessible. Monitor airway
IV/IO ketamine 1–2 mg/kg — for severe, dangerous agitation not responding to above
Avoid haloperidol in young children. All sedation: continuous SpO₂ monitoring, resuscitation equipment available
ADHD Specific
Medication crisis: missed stimulant dose → rebound hyperactivity. Give regular medication if known ADHD
Assess for comorbidities: ODD, conduct disorder, ASD, anxiety, trauma history
Safeguarding: always consider — is the child safe at home? Is this presentation related to neglect or abuse?
Disposition: CAMHS urgent review. Consider emergency MHA assessment if risk to self or others

RCEM 2020 · SIGN · NICE
💊 Drug Options & Monitoring
Pre-Sedation Checklist
ASA I–II ideal. Airway assessment. Fasting — RCEM: not mandatory for urgent procedures (balance risk/benefit)
Equipment: monitoring (SpO₂, ETCO₂, ECG, BP), high-flow O₂, suction, BVM, reversal agents, resuscitation trolley
Two trained persons: one for procedure, one dedicated to sedation/monitoring/documentation
Ketamine (Preferred for Paediatric ED Procedural Sedation)
IM: 4–5 mg/kg — onset 5 min, duration 20–40 min. Preferred when IV not feasible
IV: 1–2 mg/kg over 60 seconds — onset 60 seconds, duration 15–20 min. Repeat 0.5 mg/kg boluses
Glycopyrrolate 4 mcg/kg IV — reduces secretions. Midazolam 0.05 mg/kg — reduces emergence phenomena
Advantages: analgesia + sedation, maintains airway, bronchodilator. Widely used for fracture reduction, wound care, LP
Nitrous Oxide (Entonox/Equanox)
50% N₂O/50% O₂ — ideal for brief painful procedures (cannulation, wound care, LP) in cooperative children ≥3 years
Self-administered via mouthpiece or face mask. Onset 2–3 min, offset 5 min. Excellent safety profile
Contraindications: bowel obstruction, pneumothorax, middle ear disease, B₁₂ deficiency, COPD
Midazolam (Anxiolysis)
Oral: 0.3–0.5 mg/kg (max 15 mg) 30 min before procedure — excellent for anxious children for less painful procedures
IV: 0.05–0.1 mg/kg titrated (max 5 mg). Onset 2–5 min
Intranasal: 0.2–0.3 mg/kg (max 10 mg) — useful when IV not available. Onset 5–10 min. Burns nasopharynx
Reversal: flumazenil 0.01 mg/kg IV (max 0.2 mg). Can repeat. Short duration — re-sedation possible
Post-Sedation Monitoring
Continuous until: GCS 15, SpO₂ on room air, stable vital signs. Minimum 30–60 min post-ketamine
Discharge criteria: awake and alert, eating/drinking tolerated, safe discharge to responsible adult, written instructions
