Abstract

Objective: To evaluate the interaction between whole blood (WB) and blood component resuscitation in relation to mortality after trauma.

Background: WB is increasingly available in civilian trauma resuscitation, and it is typically transfused concomitantly with blood components. The interaction between WB and blood component transfusions is unclear.

Methods: Adult patients with trauma with a shock index >1 who received ≥4 combined units of red blood cells and/or WB within 4 hours across 501 U.S. trauma centers were included using the American College of Surgeons Trauma Quality Improvement Program database. The associations between (1) WB resuscitation and mortality, (2) WB to total transfusion volume ratio (WB:TTV) and mortality, and (3) balanced blood component transfusion in the setting of combined WB and component resuscitation and mortality were evaluated with multivariable analysis.

Results: A total of 12,275 patients were included (WB: 2884 vs component-only: 9391). WB resuscitation was associated with lower odds of 4-hour [adjusted odds ratio: 0.81 (0.68-0.97)], 24-hour, and 30-day mortality compared with component-only. Higher WB:TTV ratios were significantly associated with lower 4-hour, 24-hour, and 30-day mortality, with a 13% decrease in odds of 4-hour mortality for each 10% increase in the WB:TTV ratio [0.87 (95% CI: 0.80-0.94)]. Balanced blood component transfusion was associated with significantly lower odds of 4-hour [adjusted odds ratio: 0.45 (95% CI: 0.29-0.68)], 24-hour, and 30-day mortality in the setting of combined WB and blood component resuscitation.

Conclusions: WB resuscitation, higher WB:TTV ratios, and balanced blood component transfusion in conjunction with WB were associated with lower mortality in patients with trauma presenting in shock requiring at least 4 units of red blood cells and/or WB transfusion within 4 hours of arrival.
