摘要
目的:术中通过监测红细胞比容(Hematocrit,HCT)指导输血,观察输血量是否明显地减少,为规范术中输血提供试验依据。方法:选择ASAⅠ-Ⅱ级择期估计失血量≥400ml的手术患者32例,随机分为试验组及对照组,各16例。术中动态监测HCT,试验组HCT<24%后开始输血,对照组按常规方法输血。结果:试验组和对照组输血量/失血量分别为0.0585±0.1605,0.4678±0.3540(P<0.05)。结论:术中HCT指导下输血能明显减少术中用血量。
Objective： To compare the volume of transfusion with or without the guide of hematocrit determination during operation, the latter only depends on clinic experiences during operation, by this means to know the volume of transfusion whether can be decreased. To provide experimental data for transfusion trigger in operation. Methods： To choose ASA Ⅰ- Ⅱ physical status limited time operation patients randomly entered into experiment group or control group. In experimental group, we considered transfusion when hematocrit below 24%, after transfusion the hematocrit should higher than 24%. In control group, the anesthetist was unknown to the determined results of the hematocrit, he decided whether to transfuse depend on his own clinic experience. Result： The ratio of transfusion volume to blood loss volume is 0.0585±0. 1605, 0.4678±0.3540 （ P 〈 0.05） respectively in experimental group and control group. Conclusion： The transfusion volume can be decreased significantly under guiding of hematocrit determination during operation.
