π Introduction
- Pre-hospital trauma care is a rapidly developing specialty, combining clinical skills with rescue safety principles.
- β οΈ Safety first: Rescuer safety always precedes patient care.
- Framework: MARCH (Massive haemorrhage β Airway β Respiration β Circulation β Head/Disability).
π¨ Arrival at the Scene
- π Position vehicle to protect the scene & warn other traffic (beacons/lights).
- π·ββοΈ Safe exit & hazard check before approaching patient.
- π¦Ί PPE: fire-retardant overalls, boots with toecaps, gloves, helmet, and eye protection.
- π₯ Liaise with fire service to make the scene safe before patient contact.
- π "Read the wreckage": mechanism of injury predicts likely trauma pattern.
- π‘ Early communication β mobilises resources faster.
- π» Triage if multiple casualties: prioritise based on physiology and survivability.
- π Fire service may be needed for access/extrication planning.
π Exam Pearl: In major incidents, use Sieve & Sort triage. Immediate priority = airway obstruction, catastrophic haemorrhage, or compromised breathing.
π©Έ Primary Survey β MARCH
- M = Massive Haemorrhage
- Direct pressure β elevation β indirect pressure β wound packing β tourniquet β haemostatic agents.
- Chest/abdominal bleeding β rapid transfer to hospital (prehospital control not possible).
- A = Airway + C-spine
- Manual in-line stabilisation (jaw thrust, avoid head tilt/chin lift).
- Adjuncts: oropharyngeal/nasopharyngeal airway, supraglottic device if trained.
- Definitive: Intubation if feasible.
- Rescue: Surgical airway (scalpelβbougieβtube or Melker kit) if unable to ventilate.
- R = Respiration
- High-flow Oβ as soon as safe.
- Seal open/sucking chest wounds.
- Needle decompression (2nd ICS mid-clavicular or 5th ICS anterior axillary) β chest drain.
- Reassess RR, SaOβ, trachea, percussion note, chest expansion.
- C = Circulation
- IV/IO access (do not delay transfer for IV attempts).
- Permissive hypotension: Titrate fluids to palpable radial pulse (or carotid in chest trauma).
- 250ml boluses isotonic saline if shocked. Prefer blood products if available (MHP).
- Target higher BP if head injury (maintain CPP).
- H = Head / Disability
- Assume C-spine injury until excluded β collar + blocks + tape.
- Rapidly reverse hypoxia & hypotension.
- Agitated/unconscious β secure airway, prevent aspiration.
- Transport urgently to neurosurgical centre.
π₯ Trauma Team Activation Criteria
- SBP < 90 mmHg
- RR < 10 or > 30
- GCS < 12 with torso/extremity trauma
- Pregnant > 20 weeks with abnormal foetal HR
- Amputation proximal to elbow/knee
- β₯2 proximal long bone fractures
- Suspected spinal cord injury
- Severe airway-compromising maxillofacial trauma
- Burns > 15% TBSA
- Gunshot proximal to knee/elbow or trunk/head/neck
- Ejection from vehicle / pedestrian thrown
- Fall > 6 m
- β₯3 major trauma patients arriving simultaneously
- Or: Emergency doctor judgement
π Key Principle: In trauma, fix what kills first. Control haemorrhage, oxygenate, decompress chest, then stabilise for transfer. Definitive care is in hospital.
