Secondary survey

The ATLS secondary survey — the head-to-toe examination of the stable trauma patient, the AMPLE history, the clinical decision rules for the head CT (the Canadian CT Head Rule) and the cervical spine clearance (the NEXUS and the Canadian C-Spine Rule), the special investigations (the FAST and eFAST, the whole-body CT, the pelvic film), the tertiary survey and the continuous re-evaluation for the missed injury.

The one-line answer

The secondary survey is the systematic head-to-toe examination that begins only after the primary survey is complete and the patient is stable — its job is to find the injuries that were not immediately life-threatening before they become the source of preventable morbidity. Run it in order — AMPLE history, head-to-toe examination, adjuncts (FAST, X-rays, CT), and continuous re-evaluation — and apply the named decision rules (Canadian CT Head Rule, NEXUS or Canadian C-Spine Rule) so imaging is earned, not automatic. The unstable patient never gets a secondary survey: they go back to the primary survey and, if bleeding, to theatre or angiography, not the scanner.[1]

Meet the patient

A 30-year-old man is brought in after a high-speed motorbike crash, having been worked through the primary survey in the bay next door — airway protected, bilateral chest tubes for haemopneumothoraces, two large-bore cannulae, pelvis bound, and now stable enough to be transferred to your trolley. He is patient secondary survey was built for: the life threats are addressed, and your job is the head-to-toe hunt for everything else.[1]

Two questions frame every secondary survey: is he truly stable, or about to deteriorate? (reassess the vitals and the response to resuscitation continuously) and have I examined every region systematically, or have I stopped at the obvious injury? (the missed injury is the classic preventable harm). The obvious fracture is the distraction; the systematic survey is the safety net.[1]
