ABSTRACT Previous assessments linked transfusions in trauma to increased respiratory and infectious complications. However, these studies included patients with severe trauma, brisk hemorrhage, and shock. Thus, the potentially harmful impact of transfusion was difficult to determine.
A retrospective review of all trauma patients with an injury severity score (ISS) of 9 to 14 admitted to a Level 1 Trauma Center over a 5-year period was performed. Patients were stratified by transfusion history and injury severity.
Records of 2,332 patients were reviewed; 208 (8.9%) received at least 1 packed red blood cell transfusion. The incidence of complications was significantly higher in patients receiving transfusions (42.3% vs 9.0%; P < .001), and transfusion was a significant independent predictor of the development of a complication (odds ratio, 5.85; P < .001). Further, the association of transfusion with complications was dose-dependent. Transfusion was associated with a significantly increased hospital length of stay (10.6 vs 3.9 days; P < .0001).
Moderately injured trauma patients receiving transfusions suffered significantly more complications. Indications for transfusion in this population should be reassessed carefully.

    ABSTRACT: Early postinjury death after packed red blood cell (pRBC) transfusion is attributed to uncontrolled hemorrhage and coagulopathy. The adverse immunomodulatory effects of blood transfusion are implicated in subsequent morbidity. We hypothesized that injured children requiring pRBC transfusion demonstrate patterns in outcome similar to those observed in adults. Our prospectively collected trauma registry was queried for demographics, treatment, and outcome (2006-2009). Outcomes of children who received pRBC transfusion were compared with those of age- and Injury Severity Score (ISS)-matched children who did not receive pRBC transfusion by both univariate and multivariable analysis. Eight percent (43/512) of injured children received a pRBC transfusion: 20 early and 23 late. The likelihood of pRBC transfusion increased with increasing ISS (ISS <15, 2%; ISS 16-25, 17%; ISS >25, 72%). One-half of injured children who received an early pRBC transfusion died; however, most deaths were because of central nervous system injury. Both ventilator and intensive care unit days were increased in children who received pRBC transfusion as compared with those who did not. Early pRBC transfusion is associated with a high mortality in children. Late blood transfusion is associated with worse outcomes, although this relationship may not be causal. This pilot study provides evidence of an association between pRBC transfusion, morbidity, and mortality among injured children that warrants refinement in larger, prospective investigations.

    ABSTRACT: BACKGROUND: Previous observations suggest that intraoperative blood transfusion (IBT) is a risk factor for adverse postoperative outcomes. IBT alters immune function and may predispose to systemic inflammatory response syndrome (SIRS). METHODS: Patients in the American College of Surgeons National Surgical Quality Improvement Project database were studied over a 5-year period. Logistic regression identified predictors of SIRS. Propensity matching was used to obtain a balanced set of patients with equivalent preoperative risks for IBT. RESULTS: Of 553,288 inpatients, 19,968 (3.6%) developed postoperative SIRS, and 40,378 (7.2%) received IBT. Mortality in patients with SIRS was 13-fold higher than in those without SIRS (13.5% vs 1.0%, P < .001). Multivariate analysis identified the amount of blood transfused during IBT as a significant predictor for development of SIRS (odds ratio, 2.2; P < .0001). After propensity matching, 33,507 matched patients with IBT had significantly increased risk for SIRS compared with non-SIRS matched patients (12.0% vs 6.5%, P < .001). CONCLUSIONS: There is a significant association between IBT and the development of SIRS. IBT may induce SIRS, and reductions in IBT may decrease the incidence of postoperative SIRS.
