Initial management of the trauma patient.

Critical care specialists should be familiar with the initial management of injured patients. Dividing the evaluation and treatment of the patient into the primary, secondary, and tertiary surveys ensures that the multiply injured patient will be managed expeditiously. The primary survey identifies the acute life-threatening problems that must be managed immediately. The secondary survey identifies the remaining major injuries and sets priorities for definitive management. The tertiary survey identifies occult injuries before they become missed injuries.
