Major Trauma and Multiple Injuries Cheat Sheet

Major trauma involves severe injuries that can lead to death, requiring immediate and systematic management. Understanding the causes, immediate impacts, and management protocols is crucial for survival.

Core Principles

• Trauma is a leading cause of mortality, especially in younger age groups (1-44 years).
• Injuries are broadly classified as penetrating (low or high velocity) or blunt.
• Major trauma can result in immediate, early, or late death, depending on the severity and type of injury.
• Management follows a structured approach, starting with a primary survey (ABCDE) and progressing to secondary surveys and definitive treatment.
• The 'Triad of Death' (hypothermia, coagulopathy, acidosis) highlights critical factors that worsen outcomes in trauma patients.
• Early detection and management of life-threatening conditions like airway obstruction, tension pneumothorax, and severe bleeding are paramount.

Action Steps

• Perform immediate manual immobilization of the head and cervical spine.
• Assess airway patency and protect it, clearing any obstructions.
• Ensure adequate breathing and circulation, managing shock and external bleeding.
• Conduct a primary survey (ABCDE) at the accident site and continue in the emergency department.
• Initiate secondary survey, including a complete history and head-to-toe examination.
• Administer appropriate antibiotics and tetanus prophylaxis.
• Prioritize treatment based on the severity of injuries, focusing on respiratory obstruction, cardiac arrest, and blood volume replacement.

Key Terms

• Penetrating Injury: Injury caused by sharp objects or projectiles (e.g., stab wounds, gunshot wounds).
• Blunt Injury: Injury caused by impact, deceleration, or shearing forces (e.g., falls, car accidents).
• ABCDE: Primary survey sequence: Airway, Breathing, Circulation, Disability, Exposure.
• Triage: Sorting patients based on the severity of their injuries and likelihood of survival.
• Triad of Death: Hypothermia, Coagulopathy, and Acidosis, which worsen outcomes in trauma.
• EFAST Exam: Extended Focused Assessment with Sonography in Trauma, used to identify internal injuries.

Pro Tips

• In mass casualty situations, triage patients based on clinical diagnosis and available resources.
• For airway management, if a patient can speak clearly, their airway is likely patent.
• When managing bleeding, remember the 'ABC' approach: Alert ambulance, find the Bleeding, and start Compression.
• In cases of severe internal bleeding, focus on intra-thoracic, intra-abdominal, pelvic, or femur injuries.
• The 'Triad of Death' emphasizes the interconnectedness of hypothermia, coagulopathy, and acidosis in trauma patients.

Pitfalls to Avoid

• Delaying airway management can lead to rapid deterioration.
• Failure to control external bleeding can result in hemorrhagic shock.
• Ignoring potential cervical spine injuries can cause permanent neurological damage.
• Overlooking occult internal bleeding can lead to delayed treatment and worse outcomes.
• Allowing hypothermia to set in can exacerbate coagulopathy and acidosis.

Statistics

• Commonest cause of death (age 1-44): Trauma
• 3rd common cause of death (all ages): Trauma
