primary survey
The initial systematic assessment of a trauma patient focusing on immediately life-threatening injuries using the ABCDE approach (Airway, Breathing, Circulation, Disability, Exposure).
Full Definition
The primary survey is the cornerstone of trauma evaluation, designed to identify and treat immediately life-threatening conditions in a systematic manner. Following the ABCDE sequence, the primary survey begins with airway assessment and management, including cervical spine protection. Breathing evaluation includes inspection, palpation, and auscultation for pneumothorax, flail chest, or other respiratory compromise. Circulation assessment focuses on identifying hemorrhage and shock through pulse, blood pressure, and perfusion evaluation. Disability evaluation involves a brief neurological assessment including Glasgow Coma Scale and pupillary response. Exposure requires complete undressing while preventing hypothermia. Each step must be completed and any problems addressed before moving to the next. The primary survey is repeated frequently to detect changes in patient condition and guide ongoing resuscitation efforts.
Usage
Usage note: Always use lowercase 'survey' and distinguish clearly from 'secondary survey' which focuses on detailed evaluation.
