Scene, Safety & First Impression
- Dynamic risk assessment — danger to self, crew, patient, bystanders (traffic, fire, hazmat, hostile persons); don appropriate PPE.
- Rationale: you are no use as a second casualty.
- Mechanism of injury (MOI) — speed, height, restraints, ejection, entrapment, penetrating vs blunt.
- Rationale: MOI is not a diagnosis but shapes your index of suspicion and choice of rapid vs focused survey.
- General impression — is the patient talking? colour, posture, obvious external injury.
- Rationale: a talking patient implies patent airway, adequate breathing and cerebral perfusion in one glance.
Primary Survey — <C>ABCDE
Principle Treat first what kills first. Do not move to the next letter until any life threat found is addressed.
<C> — Catastrophic Haemorrhage
- Look for pooling/spurting blood, soaked clothing.
- Control: direct pressure → wound packing with haemostatic gauze → windlass tourniquet applied proximally for uncontrolled limb bleeding.
- Consider early tranexamic acid (TXA) — 1g IV over 10 min, within 3 hrs of injury.
- Rationale: assessed before airway because exsanguination can kill faster than airway compromise. Remember internal reservoirs — "blood on the floor and four more": chest, abdomen, pelvis, long bones.
A — Airway (with C-spine control)
- Can they talk clearly? Look for blood, vomit, teeth, secretions, facial/neck trauma, airway burns (soot, singed nasal hair, stridor).
- Listen for gurgling/snoring (partial obstruction).
- Manage: manual manoeuvres (jaw thrust if C-spine risk) → suction → adjuncts (OP/NP) → supraglottic/RSI (critical care/HEMS) as indicated.
- Maintain manual in-line stabilisation throughout.
- Rationale: reduced GCS = loss of pharyngeal tone = tongue occludes airway. Airway always takes priority over spinal precautions if the two conflict.
B — Breathing
- Look: rate, depth, symmetry, work of breathing, wounds, bruising (seatbelt sign), flail segment, accessory muscle use.
- Feel: tracheal position, surgical emphysema, chest-wall tenderness/instability.
- Listen/percuss: equal air entry, hyperresonance/dullness.
- Apply SpO₂, titrate oxygen.
- Exclude tension pneumothorax, open pneumothorax, massive haemothorax, flail chest.
- Rationale: tracheal deviation is a late, insensitive sign — decompress on respiratory distress + unilateral absent breath sounds + haemodynamic compromise, don't wait for deviation.
C — Circulation
- Assess pulse rate/quality, skin colour/temp/moisture, cap refill, BP.
- Re-check external haemorrhage control; examine occult reservoirs (chest, abdomen, pelvis, long bones).
- Apply pelvic binder over greater trochanters if suspected pelvic injury.
- Gain IV/IO access; give TXA; consider blood products where available.
- Permissive hypotension in penetrating/uncontrolled haemorrhage — aim for palpable central pulse, not normal BP.
- Rationale: avoid "popping the clot" by over-resuscitating before surgical control is available.
D — Disability
- AVPU rapid screen → full GCS (record E/V/M components).
- Pupils — size, equality, reactivity.
- Limb movement, blood glucose (hypoglycaemia mimics head injury).
- Watch for raised ICP / herniation: falling GCS, unilateral fixed dilated pupil, Cushing's response (hypertension, bradycardia, irregular respiration).
- Rationale: GCS ≤8 = unprotected airway + severe brain injury. Avoid hypoxia/hypotension — they cause secondary brain injury.
E — Exposure & Environment
- Fully expose — check back, axillae, perineum, skin folds for hidden injury.
- Actively warm — blankets, warm vehicle.
- Rationale: hypothermia worsens coagulopathy — part of the lethal triad (hypothermia, acidosis, coagulopathy).
Load & Go / Red Flags
Uncorrectable A/B/C problem · catastrophic haemorrhage · GCS ≤8 or falling · penetrating torso injury · suspected pelvic or multiple long-bone fractures · signs of shock · significant mechanism + abnormal physiology → minimal scene time, essential interventions only, pre-alert MTC.
Traumatic Cardiac Arrest
Prioritise reversible causes simultaneously — HOTT: Hypovolaemia, Oxygenation/hypoxia, Tension pneumothorax, Tamponade. Compressions de-emphasised until reversible causes addressed (FPHC 2024 position).
Secondary Survey — Head to Toe
Performed after the primary survey / life threats controlled — often completed en route in major trauma.
DeformitiesContusionsAbrasions
Punctures/penetrationsBurnsTenderness
LacerationsSwelling
Plus TIC over bones (Tenderness, Instability, Crepitus). Take a parallel focused history with AMPLE (Allergies, Medications, Past history, Last oral intake, Events/Environment).
Head & Scalp
- Palpate entire scalp (check gloves for blood); DCAP-BTLS; depressed/boggy skull fractures.
- Basal skull fracture signs: raccoon eyes, Battle's sign (late), CSF/blood from ears or nose, haemotympanum.
- Rationale: signals significant head injury, risk to airway/brain, contraindicates nasal airways/tubes.
Face
- Inspect/palpate orbits, nose, maxilla, mandible — deformity, instability, malocclusion, bleeding into airway.
- Rationale: facial fractures threaten the airway and can signal underlying brain/C-spine injury.
Eyes
- Pupils (size, equality, reactivity), gross visual acuity, foreign bodies, contact lenses, periorbital injury.
- Rationale: check early, before swelling closes the lids.
Neck (maintain C-spine control)
- Second rescuer holds manual in-line stabilisation; open collar to assess.
-
Tracheal deviationWoundsEmphysema (surgical)
Laryngeal crepitusVenous distensionEmidline tenderness/step
- Rationale: tracheal deviation/JVD → tension pneumothorax/tamponade; midline tenderness/step → C-spine injury; penetrating neck wound = surgical emergency. Re-secure C-spine after.
Chest
- Re-inspect, palpate every rib + clavicles/sternum, re-auscultate/percuss.
- Bruising patterns, paradoxical movement, tenderness/crepitus.
- Rationale: multiple/first-second rib fractures = high energy transfer + underlying lung/vascular injury; sternal injury raises suspicion of cardiac contusion.
Abdomen
- Look: bruising (seatbelt sign, Grey-Turner's/Cullen's — late), distension, wounds, evisceration.
- Feel: all four quadrants — tenderness, guarding, rigidity.
- Rationale: major site of concealed haemorrhage. A soft abdomen in an obtunded patient is not reassuring.
Pelvis
- Inspect — deformity, wounds, scrotal/perineal bruising, PV/PR blood, leg-length/rotation discrepancy.
- Palpate gently, once for tenderness.
- Never "spring" the pelvis (repeated compression/distraction).
- If any suspicion — apply pelvic binder over greater trochanters; do not re-examine further.
- Rationale: springing is a poor predictor (sensitivity ~59%, specificity ~71%) and can dislodge clot, worsening haemorrhage. The binder is a haemorrhage-control treatment — "if unsure, apply it."
Back & Spine
- Controlled log roll (or scoop/orderly lift) to inspect/palpate whole spine, posterior chest, flanks.
- DCAP-BTLS + midline tenderness/step.
- Rationale: posterior wounds, spinal injury and occult bleeding are easily missed if the back is never seen. In time-critical major haemorrhage, formal log roll may be deferred.
Limbs (all four)
- DCAP-BTLS + TIC on each limb; active/passive movement where appropriate.
- Neurovascular status distal to every injury — pulses, cap refill, colour, temperature, sensation, motor — compare left vs right.
- Recheck after any splinting/realignment.
-
PainPallorParaesthesia
PulselessnessParalysisPoikilothermia
- Rationale: the 6 Ps flag compartment syndrome / vascular injury — pain out of proportion is often the earliest sign.
Skin / Full Body
- Overall pallor, cyanosis, mottling, rashes, medical-alert jewellery.
- Complete picture of burns, entry/exit wounds, injection sites.
Rapid vs Focused Survey — How to Choose
| Rapid Trauma Survey | Focused Exam |
| Significant mechanism · altered mental status · suspected multi-system trauma. Whole-body scan (~60–90s) alongside primary survey. Only life-saving interventions on scene; detailed exam completed en route. |
Stable patient, isolated injury, no concerning mechanism, GCS 15. Examine specific injury + relevant systems; often non-MTC destination. |
Golden rule If the patient deteriorates at any point during the secondary survey — abandon it and return to <C>ABCDE.
Handover — ATMIST / ATMISTER
Structured hands-off handover to the assembled trauma team, ~30–60 seconds.
| Letter | Element | Why it matters |
| A | Age (+ sex/name) | Age/weight-appropriate equipment, drug doses, blood |
| T | Time of incident/key events | TXA window, ischaemic time, trending |
| M | Mechanism | Predicts injury pattern, primes index of suspicion |
| I | Injuries (found + suspected) | Directs specialties, imaging, interventions |
| S | Signs (obs + trend) | Trajectory matters more than a snapshot |
| T | Treatment given + response | Prevents duplication, flags what worked |
| E (pre-alert) | ETA | Team assembly timing |
| R (pre-alert) | Requirements/Requests | Blood, trauma team, surgeon, CT, paeds team ready on arrival |
AMPLE (Allergies, Medications, Past history, Last oral intake, Events) — background history, usually given after ATMIST once patient is on the trolley.
Delivery Best Practice
- Pre-alert early via control/red phone so the team can assemble and prepare blood, imaging, theatre.
- One clinician (usually lead paramedic) delivers a single, structured, hands-off handover.
- No simultaneous patient transfer or task distraction during handover.
- Team leader identifies self, ensures whole team is listening, takes questions after ATMIST and again after AMPLE — not during.
- Capture contemporaneously (ATMIST slate/card); leave written copy/PCR.
- Only an immediate uncorrected life threat (e.g. need for CPR) should interrupt the structured handover.
