创伤手术的一段看不懂？

Damage Control Resuscitation (DCR) is a systematic approach to the trauma patient with severe injuries, starting in the emergency room and continuing through both operative and post-op management in the intensive care unit. It encompases damage control surgery and its tenants of temporizing surgical hemorrhage and gastrointestinal spillage as well as principles of balanced resuscitation [7]. The major goalof balanced resuscitation is prevention and immediate correction of coagulopathy, and minimizing use of crystalloid fluids.
