Damage control surgery is a technique used for seriously injured patients that prioritizes short-term physiological recovery over anatomical reconstruction. It involves abbreviated laparotomy to control bleeding and contamination, followed by intensive care resuscitation to correct hypothermia, coagulopathy, and acidosis, and then definitive surgery within 36-48 hours. The goal is to prevent the "lethal triad" of hypothermia, acidosis, and coagulopathy that can lead to multiple organ failure and death in trauma patients.
