Documentation is a legal requirement. Timestamp every intervention, drug, and clinical finding. Use 24-hour clock. If it is not documented, it did not happen.
Patient age and relevant pre-existing conditions if known.
Exact time injury occurred. Relevant for TXA window (within 3 hours) and ischaemia timing.
How the injury happened. High-speed RTA, fall height, type of penetrating object.
Confirmed injuries on scene. "Suspected" if not confirmed. Do not anchor — reassess everything on arrival.
GCS, SBP, HR, RR, SpO2 at scene. Trend is important — improving or deteriorating?
Fluids administered, drugs given, tourniquet applied and time, chest seal placed.
cABCDE order is mandatory. Catastrophic haemorrhage control BEFORE airway. Each step must be completed and life threats treated before moving to the next. Call for help — do not work alone.
External life-threatening haemorrhage must be controlled before airway management. Visible exsanguinating haemorrhage kills in minutes.
Do NOT remove pelvic binder once applied — even for secondary survey. Binder reduces pelvic volume and allows clot formation.
Signs: absent breath sounds one side, hypotension, tachycardia, raised JVP, tracheal deviation (late). SpO2 plummeting. Do not wait for CXR — treat clinically.
Dose 1: 1g IV over 10 minutes
Dose 2: 1g IV over 8 hours
Time window: within 3 hours of injury. After 3 hours — harmful, do NOT give.
| Class | Blood Loss | HR | SBP | GCS |
|---|---|---|---|---|
| I | <750 mL (<15%) | <100 | Normal | Normal |
| II | 750–1500 mL (15–30%) | 100–120 | Normal/↓ | Anxious |
| III | 1500–2000 mL (30–40%) | 120–140 | ↓↓ | Confused |
| IV | >2000 mL (>40%) | >140 | Critical | Lethargy |
Unilateral fixed dilated pupil: ipsilateral uncal herniation until proven otherwise. Urgent neurosurgical review.
Lethal Triad: Hypothermia + Acidosis + Coagulopathy. Recognition and targeted reversal of all three components simultaneously is the cornerstone of trauma resuscitation. Each potentiates the others.
RBC : FFP : Platelets = 1 : 1 : 1
Prevents dilutional coagulopathy. Mirrors whole blood resuscitation.
Fibrinogen: target >1.5 g/L — give cryoprecipitate or fibrinogen concentrate early.
Aggressive fluid resuscitation raises BP and dislodges clot — "popping the clot." Permissive hypotension maintains minimum perfusion while preserving haemostasis until surgical control is achieved.
Hypotonic or glucose-containing fluids are contraindicated in TBI — worsen cerebral oedema.
Resuscitate while preparing for theatre — these are not sequential. Activate theatre while primary survey ongoing if major haemorrhage is confirmed.
Secondary survey begins ONLY after primary survey is complete and life threats are addressed. Resuscitation must be underway. If patient re-deteriorates, return to primary survey (cABCDE) immediately.
Drug allergies, contrast allergies (important for CT angiography). NSAID/aspirin intolerance.
Anticoagulants (warfarin, NOAC, heparin), antiplatelets, beta-blockers (mask tachycardia), steroids.
Bleeding disorders, liver disease, cardiac conditions, previous surgery.
Fasting status — critical for RSI/GA. Risk of aspiration. Note for anaesthetics team.
Was there a medical cause of the trauma? (Collapse, seizure, MI causing RTA). "Medical cause of trauma" must be excluded.
Pelvic binder at the level of the greater trochanters — NOT the iliac crests. Reduces pelvic volume. Do NOT remove once applied. Haemodynamic instability + pelvic fracture = angioembolisation referral.
Bilateral pupils fixed and dilated = immediate neurosurgery. Mannitol 1g/kg stat, intubate, transfer.
No longer routinely recommended (NASCIS III). May be considered by spinal surgeon within 8 hours of acute injury — consultant decision only.
Impairs platelet function and clotting factor activity. Treatment: warm fluids, warming blanket, raise room temp to 26–28°C.
Coagulopathy worsens below pH 7.1. Treatment: restore tissue perfusion, surgical haemostasis, buffer with sodium bicarbonate only if refractory.
Trauma-induced coagulopathy begins within minutes of severe haemorrhage. Treatment: MTP 1:1:1, TXA, fibrinogen concentrate/cryoprecipitate, calcium.
| Category | Criterion | Action |
|---|---|---|
| Mechanism | RTA >60 km/h, fall >3m, penetrating torso/head, pedestrian vs vehicle | Full trauma team activation |
| Physiology | GCS <14 | Trauma team + CT head |
| Physiology | SBP <90 mmHg | MTP pre-alert, blood bank activate |
| Physiology | RR <10 or >29 | Anaesthetics to bedside |
| Anatomy | Flail chest, open femur, pelvic fracture, spinal injury | Full activation + orthopaedics |
Wrong: Head-tilt/chin-lift in trauma patient.
Correct: Jaw thrust with C-spine protection.
Wrong: Spring the pelvis to assess for fracture.
Correct: Single palpation only — do NOT spring.
Wrong: TXA at any time after injury.
Correct: Only within 3 hours. After 3h, TXA increases mortality.
Remember: Normal HR in elderly/beta-blocked does NOT rule out significant haemorrhage.
