Trauma Assessment for Paramedics: A Practical Guide

Why Trauma Assessment Matters in Pre-Hospital Care

Trauma remains one of the leading causes of preventable death in the UK, and the decisions a paramedic makes in the first few minutes on scene can be the difference between life and death. Unlike the controlled environment of an emergency department, pre-hospital trauma management demands rapid, systematic thinking under pressure — often in challenging conditions with limited resources.

For student paramedics, developing a reliable, repeatable approach to trauma assessment is one of the most critical skills you will build during your training. This guide walks through the key frameworks used in UK pre-hospital practice, grounded in JRCALC guidelines and NHS clinical expectations.

Scene Safety and Situational Awareness

Before you even reach the patient, your assessment has already begun. Scene safety is not a box-ticking exercise — it is active, ongoing evaluation. Ask yourself:

• Is the mechanism of injury still present (e.g. moving traffic, unstable structures, live electricity)?
• How many patients are there? Could this be a major incident?
• What resources do I have, and what do I need to request?
• Is my personal protective equipment appropriate?

Situational awareness also feeds into your index of suspicion. A patient who has fallen from height, been involved in a high-speed road traffic collision, or sustained a penetrating injury should be treated as a serious trauma case until proven otherwise — even if they appear stable on first impression.

The CABAN-C Approach: Haemorrhage Control First

Traditional ABCDE assessment has evolved in pre-hospital trauma care. The UK military and civilian pre-hospital communities now widely endorse a CABAN-C or <C>ABCDE approach, where catastrophic haemorrhage control comes before airway management.

This shift is evidence-based: exsanguination from compressible wounds is a leading cause of preventable traumatic death. If a patient is bleeding to death from a limb wound, securing their airway first is the wrong priority.

Catastrophic Haemorrhage (<C>)

Identify and control life-threatening external bleeding immediately. Interventions include:

• Direct pressure — sustained, firm pressure to the wound
• Tourniquets — indicated for limb haemorrhage not controlled by direct pressure; note time of application
• Haemostatic dressings — such as those containing kaolin or chitosan, used in junctional or wound-packing scenarios
• Wound packing — for junctional wounds (groin, axilla, neck) where tourniquets cannot be applied

ABCDE Assessment in Trauma

Once catastrophic haemorrhage is controlled, move through a structured ABCDE assessment, adapting each component to the trauma context.

A — Airway

Assess for airway patency while maintaining manual inline stabilisation (MILS) if spinal injury is suspected. Look, listen, and feel. Is the patient vocalising? Can you see blood, vomit, or foreign bodies? Simple adjuncts such as a nasopharyngeal airway (NPA) or oropharyngeal airway (OPA) may be appropriate. In unconscious trauma patients, a definitive airway via supraglottic device or endotracheal intubation may be required — escalate accordingly.

B — Breathing

Expose the chest and assess for life-threatening breathing problems. Key conditions to identify include:

• Tension pneumothorax — tracheal deviation (late sign), absent breath sounds, hypotension, distended neck veins; treat with needle chest decompression
• Open pneumothorax — seal with a vented chest seal
• Massive haemothorax — dull percussion, absent breath sounds, haemodynamic compromise
• Flail chest — paradoxical chest wall movement, associated pulmonary contusion

Provide supplemental oxygen and ventilatory support as indicated. Avoid hyperventilation, which can worsen outcomes in traumatic brain injury.

C — Circulation

Beyond catastrophic haemorrhage already controlled, assess for signs of haemorrhagic shock. In the trauma patient, assume hypotension is due to blood loss until proven otherwise. Key assessments include pulse rate, character and location (radial versus carotid), capillary refill time, skin colour and temperature, and mental status as a proxy for cerebral perfusion.

In the UK pre-hospital setting, permissive hypotension is now standard practice for penetrating trauma — targeting a systolic of around 80–90 mmHg in patients without traumatic brain injury (TBI), to avoid dislodging clots before surgical haemostasis. For patients with suspected TBI, maintain a higher systolic (above 110 mmHg) to ensure adequate cerebral perfusion pressure.

Establish vascular access (IV or IO) and administer tranexamic acid (TXA) early if within 3 hours of injury and significant haemorrhage is suspected — this is a JRCALC-endorsed intervention with strong evidence behind it.

D — Disability

Perform a rapid neurological assessment using the AVPU scale or Glasgow Coma Scale (GCS). Assess pupils for size, equality, and reactivity. Check blood glucose — hypoglycaemia can mimic or complicate traumatic brain injury. A declining GCS in a trauma patient is a red flag demanding urgent reassessment and expedited transport.

E — Exposure and Environment

Expose the patient fully to identify all injuries, including the back — log roll where spinal injury is possible. Once assessed, cover the patient to prevent hypothermia. The lethal triad of hypothermia, acidosis, and coagulopathy is a well-recognised killer in major trauma; active prevention of heat loss begins on scene.

Secondary Survey and Ongoing Monitoring

If time and clinical condition allow — typically during transport — conduct a head-to-toe secondary survey. This is a more detailed assessment to identify injuries not immediately life-threatening but requiring intervention or documentation. Reassess vital signs regularly, particularly after any intervention, and communicate clearly with the receiving major trauma centre (MTC) or trauma unit.

Packaging and Transport Decisions

The principle of "load and go" applies in major trauma — definitive haemorrhage control is surgical, and prolonged on-scene times worsen outcomes. The platinum ten minutes concept encourages paramedics to limit scene time and move critical trauma patients rapidly toward definitive care. Pre-alert the receiving hospital with a structured handover using ATMIST or SBAR format to prepare the trauma team.

Documentation and Clinical Handover

Accurate, contemporaneous documentation is both a professional and clinical obligation. Record mechanism of injury, findings at each stage of assessment, interventions with times (especially TXA and tourniquet application), trends in vital signs, and patient response to treatment. A clear, concise handover using a structured tool such as ATMIST (Age, Time, Mechanism, Injuries, Signs, Treatment) ensures continuity of care and supports the trauma team in their immediate decision-making.
