Complications of Hemorrhagic Shock and Massive Transfusion – A Comparison before and after the Damage Control Resuscitation ERA

Trauma remains a leading cause of death, and hemorrhage is the leading cause of preventable trauma deaths. Resuscitation strategies in trauma have changed dramatically over the last 20 years. In the pre damage control resuscitation (DCR) era, we used large volume crystalloid resuscitation and packed red blood cells as the primary resuscitative fluids. Now, a 1:1:1 ratio of packed red blood cells, fresh plasma, and platelets with minimal crystalloids is the preferred resuscitative strategy (DCR era). As we have changed how we resuscitate patients, the detrimental effects associated with large volume resuscitation have also changed. In this article, we review the effects of large volume blood product resuscitation, and where possible present a contrast between the pre-DCR era and the DCR era resuscitation strategies.
