The pediatric resuscitative thoracotomy during combat operations in Iraq and Afghanistan - A retrospective cohort study.

Background: Combat zone trauma poses a unique set of challenges and injury patterns not seen in the civilian setting. The role of the pediatric resuscitative thoracotomy in combat zones remains unclear given a paucity of data regarding procedure outcomes in this setting. We compare outcomes among children in traumatic arrest undergoing resuscitative thoracotomy versus cardiopulmonary (CPR) resuscitation only.
