Injured patients stress the transfusion service with frequent demands for uncrossmatched red cells and plasma, occasional requirements for large amounts of blood products and the need for new and better blood products. Transfusion services stress trauma centers with demands for strict accountability for individual blood component units and adherence to indications in a clinical field where research has been difficult, and guidance opinion-based. New data suggest that the most severely injured patients arrive at the trauma center already coagulopathic and that these patients benefit from prompt, specific, corrective treatment. This research is clarifying trauma system requirements for new blood products and blood-product usage patterns, but the inability to obtain informed consent from severely injured patients remains an obstacle to further research.
受伤患者频繁要求输注未交叉配血的红细胞和血浆,偶尔需要大量血液制品,并且需要新的更好的血液制品,这给输血服务带来了压力。输血服务给创伤中心带来了压力,要求对每个血液成分单位进行严格的核算,并遵守在研究困难且以意见为导向的临床领域的适应症。新数据表明,最严重的受伤患者到达创伤中心时已经出现凝血功能障碍,这些患者从及时、具体、纠正性治疗中获益。这项研究阐明了创伤系统对新血液制品和血液制品使用模式的要求,但由于无法从重伤患者那里获得知情同意,进一步的研究仍然存在障碍。
