目的观察术野回收式自体输血技术用于患者术中血液保护的临床效果。方法选择医院需要麻醉手术患者98例为研究对象,根据输血方式的不同分为观察组和对照组,每组49例。观察组采用术野自身回收洗涤红细胞输入和少量异体凝结红细胞输入,对照组采用异体浓缩红细胞输入。观察比较2组患者输血前后游离血红蛋白(Hb)、红细胞压积(Hct)数值变化及输血后不良反应发生情况。结果输血后,2组Hb、Hct数值均有明显好转,观察组效果优于对照组(P<0.05)。观察组异体血量少于对照组(P<0.05);2组总输血量比较差异无统计学意义(P>0.05)。观察组不良反应发生率为0,低于对照组的16.33%(P<0.01)。结论手术中需要大量输血的患者采用回收式自体输血技术,不仅能有效节约血液资源,而且还能避免血液传播性疾病,减少输血后不良反应,促进患者早日康复。
Objective To observe the clinical effect of surgical field recovery autologous blood transfusion for patients with intraoperative blood protection. Methods A total of 98 patients undergoing anesthesia in the hospital were enrolled in this study. According to the different methods of transfusion, they were divided into observation group and control group, 49 cases in each group. The observation group used the surgical field to recover the input of washed red blood cells and a small amount of allogeneic condensed erythrocytes, while the control group received allogenic red blood cells. The changes of free hemoglobin (Hb), hematocrit (Hct) and the adverse reaction after transfusion were observed and compared between the two groups. Results After transfusion, the values of Hb and Hct in both groups were significantly improved, and the observation group was better than the control group (P <0.05). The blood volume of the observation group was less than that of the control group (P <0.05). There was no significant difference in the total blood transfusion between the two groups (P> 0.05). The incidence of adverse reactions in the observation group was 0, which was lower than 16.33% of the control group (P <0.01). Conclusion Reciprocal autologous blood transfusion is required in patients undergoing massive transfusions, which not only effectively saves blood resources, but also avoids blood-borne diseases, reduces post-transfusion adverse reactions, and promotes early recovery.
