This document discusses trauma resuscitation in the emergency department. It outlines the initial assessment process, including preparation, triage, primary survey, resuscitation, need for transfer, secondary survey, continued monitoring and definitive care. The primary survey focuses on airway and breathing, circulation with hemorrhage control, disability (neurological status), and exposure/environmental control. Specific approaches to assessing and managing issues in each of these areas are described in detail. Case examples are also provided to demonstrate applying the trauma resuscitation process.
