In the assessment of polytrauma, a systematic primary survey prioritizes life-saving interventions: securing the airway with cervical spine protection, assessing breathing (e.g., flail chest, pneumothorax), circulation (e.g., hemorrhage, shock), disability (neurological status via GCS), and exposure while preventing hypothermia. Life-threatening injuries include tension pneumothorax, cardiac tamponade, massive hemorrhage, and intracranial bleeds. The secondary survey involves a head-to-toe examination, history taking, and stabilization. Key outpatient management includes oxygen, spinal precautions, IV fluids, and urgent referral without delay for definitive care. Immediate interventions vary by system, such as chest tube insertion, fluid resuscitation, or immobilization for fractures.
