大量成分输血对患者凝血机制的干预分析

Intervention analysis of a large nmber of component blood transfsion on blood coaglation mechanism

目的探讨大量成分输血对患者凝血机制的干预。方法 73例大量成分输血患者,输注悬浮红细胞量平均11 U,输注冰冻血浆量平均8 U。输血前、输血后4 h检测凝血指标。结果 73例患者输血前后凝血因子差异有统计学意义(P均<0.01);血小板显著下降,差异有统计学意义(P<0.01)。结论大量成分输血对凝血功能有重要影响,应及时检测凝血因子及血小板,并通过血液加温以及针对性的补充血小板和凝血因子来减少出血风险。

ObjectiveTo analyze intervention of a large number of component blood transfusion on blood coagulation mechanism.MethodsRetrospectively analyzed clinical data of 73 patients with a large number of component blood transfusion. The infusion of suspension red blood cell volume average of 11 U, infusion of average frozen plasma volume of 8 U. Blood clotting index 4 h before and after blood transfusion was detected.Results73 cases of patients before and after blood transfusion blood coagulation factor had significant changes, the difference was statistically significant（P〈0.01）, blood platelet reducted significantly, the difference was statistically significant（P〈0.01）.ConclusionA large number of component blood transfusion has important influence on blood coagulation function, blood platelet and clotting factors should be timely detected, and through blood heat and corresponding platelet and blood coagulation factor supplementary to reduce risk of bleeding.
