EARLY TRAUMA LIFE SUPPORT IN THE FIELD

Lesson Overview

This lesson provides undergraduate MBBS students with a structured, practical approach to the initial assessment and early management of a trauma patient at the scene of injury. The emphasis is on recognising life-threatening conditions early, initiating appropriate immediate interventions, protecting the cervical spine, controlling major haemorrhage, and arranging timely transfer to definitive medical care.

Students will first learn how to approach a trauma patient safely, including scene safety, use of personal protective equipment, assessment of responsiveness, and recognition of whether the patient is conscious or unconscious. The lesson then introduces the appropriate pathway for each situation.

For the conscious trauma patient, students will learn and practise the HABCDE Primary Survey, with emphasis on identifying and treating life-threatening problems as they are found.

H – Haemorrhage

Students will learn to rapidly identify catastrophic external bleeding and demonstrate appropriate bleeding-control techniques, including:

• Direct pressure
• Pressure dressing/bandage
• Recognition of major or life-threatening bleeding
• Appropriate use of a commercial tourniquet for severe limb haemorrhage
• Reassessment of bleeding control

A – Airway and Cervical Spine Protection

Students will learn to assess airway patency while maintaining appropriate cervical spine precautions when significant trauma is suspected. Practical demonstration will include manual cervical spine stabilisation / three-point immobilisation.

B – Breathing

Students will practise rapid assessment of respiratory rate, chest movement, respiratory effort and signs of respiratory compromise.

C – Circulation

Students will learn to assess pulse, peripheral perfusion, signs of shock and ongoing blood loss, while understanding the importance of early recognition of circulatory compromise.

D – Disability

Students will perform a rapid neurological assessment using AVPU – Alert, Voice, Pain and Unresponsive, while recognising deterioration in consciousness as an important warning sign.

E – Exposure and Environment

Students will learn how to expose the patient sufficiently to identify significant injuries while maintaining dignity and preventing hypothermia.

Unconscious Trauma Patient – BLS Pathway

The lesson also teaches students how to respond when a trauma patient is unconscious. Students will recognise the need to rapidly assess responsiveness and breathing, activate emergency assistance and initiate the BLS pathway, including CPR and AED use when indicated.

The importance of balancing cervical spine precautions with immediate life-saving interventions such as airway management and CPR will be emphasised.

Practical Skills

During the skills session, students will practise:

• Safe approach to a trauma patient
• Responsiveness assessment
• HABCDE Primary Survey
• BLS pathway for an unconscious trauma patient
• Manual cervical spine stabilisation
• Recognition of minor versus major bleeding
• Direct pressure
• Pressure bandage application
• Tourniquet application on a training limb
• Reassessment following intervention
• Team communication and role allocation

Simulation Activity

Students will participate in an integrated simulated trauma scenario, such as a road traffic accident. Working as a team, they will assess the patient, identify immediate life threats, control bleeding, provide cervical spine protection, perform HABCDE assessment, and communicate the need for further emergency care.

Faculty will observe the performance and provide immediate feedback, focusing on patient safety, prioritisation, technical skill, communication and clinical decision-making.

Learning Outcomes

By the end of this lesson, the student should be able to:

1. Demonstrate a safe and systematic approach to a trauma patient.
2. Differentiate between the conscious and unconscious trauma patient.
3. Perform the HABCDE Primary Survey in the correct sequence.
4. Recognise when the BLS pathway is required.
5. Demonstrate appropriate cervical spine protection.
6. Recognise life-threatening external haemorrhage.
7. Demonstrate direct pressure and pressure-bandage techniques.
8. Demonstrate appropriate tourniquet application for severe limb bleeding.
9. Recognise clinical features suggesting shock or deterioration.
10. Reassess the patient after each intervention.
11. Demonstrate effective teamwork and communication during a trauma emergency.
12. Understand the importance of early escalation and transfer to definitive trauma care.

Assessment

Student competency will be assessed through Direct Observation of Procedural Skills (DOPS) and simulation-based formative assessment.

Assessment will focus on:

• Safe patient approach
• Correct prioritisation
• HABCDE performance
• Cervical spine protection
• Haemorrhage control
• Tourniquet technique
• BLS recognition
• Communication and teamwork
• Reassessment and escalation

Key Take-Home Message

“Recognise what can kill the patient first, treat it immediately, reassess continuously, and arrange rapid transfer to definitive care.”
