Supplement 20: Should We Use Damage Control Resuscitation (DCR)? One of the most frequently discussed potential advances in contemporary trauma care is the concept of “DCR” [[1-4]]. DCR involves utilization of permissive hypotension, limitation of crystalloid intravenous fluids, and delivering higher ratios of plasma and platelets to red blood cells than has conventionally been used [[1]]. Evidence Summary: In a single-institution, retrospective cohort study of 390 patients undergoing damage control laparotomy, DCR patients received less crystalloids (14 L versus 5 L), packed red blood cells (13 units versus 7 units), plasma (11 units versus 8 units), and platelets (6 units versus 0 units) as compared to those who did not receive DCR and peak IAPs were reported to be lower in the DCR group [[1]]. Another single-center, retrospective cohort study reported that the risk of ACS decreased (9.9% versus 0%, p<0.001) among severely injured trauma patients after institution of a DCR trauma exsanguination protocol [[5]]. This study also reported that use of this protocol decreased the adjusted odds of developing multi-organ failure (OR, 0.20; 95% CI, 0.11 to 0.40) and increased the adjusted odds of achieving primary abdominal fascial closure (OR, 5.6; 95% CI, 2.5 to 12.7) [[5]]. However, a recent systematic review [[6, 7]] identified 11 observational (including three prospective [[8-10]], seven retrospective [[11-17]], and one historical case-control [[18]]) studies that examined treatment of trauma-associated coagulopathy with transfusion of high plasma to packed red blood cell ratios. As several methodological limitations, including survival bias, has limited the examination of the effect of DCR on mortality, this systematic review concluded that insufficient evidence existed to support a survival advantage with DCR. A summary of Studies Table is available online at Supplement A9 - Summary of Studies for Damage Control Resuscitation. Reccomendation: The WSACS SUGGESTS that an enhanced ratio of plasma/packed red blood cells should be used for resuscitation of massive hemorrhage versus low or no attention to plasma/packed red blood cell ratios (Management suggestion 5; GRADE 2D). Rationale: Although DCR may avoid crystalloid over-resuscitation and possibly IAH/ACS, its impact on many patient-important outcomes remains unknown. References 1. 2. 3.
