This document outlines the steps for primary and secondary surveys according to the Advanced Trauma Life Support (ATLS) 9th edition guidelines. The primary survey focuses on assessing and stabilizing the airway, breathing, circulation, disability (level of consciousness), and exposure. Interventions include endotracheal intubation, chest tube insertion, intravenous fluid resuscitation, and monitoring of vital signs. The secondary survey involves a full head-to-toe examination and additional diagnostic imaging tests to evaluate for injuries that may not be evident on primary survey. Reevaluation includes continuous monitoring, pain management, immunizations, and antibiotics as needed.
