自体血逆预充技术在体外循环心脏手术中的血液保护作用

Blood Protection Effect of Autoblood Precharging Technique in Extracorporeal Circulation Cardiac Surgery

目的探讨自体血逆预充技术在体外循环心脏手术中的血液保护作用。方法选取在我院进行体外循环心脏手术患者40例,随机将其分为对照组和试验组,各组20例。对照组只实施常规血液保护措施,试验组则在此基础上加以自体血逆预充技术的实施。记录分析围术期的红细胞压积、输血量和输血率,以及术后患者的恢复情况等。结果两组患者皆成功实施了体外循环心脏手术,且都无死亡和重大的手术并发症现象发生。试验组的患者红细胞比容值高于对照组,试验组患者在围术期的输血量和输血率均低于对照组(P<0.05)。结论使用自体血逆预充技术可有效降低体外循环过程当中过度的血液稀释,维持较高的红细胞压积值,从而减少围术期的输血量和输血率,达到节约用血的作用。

Objective To investigate blood protective effect of autoblood precharging technique in extracorporeal circulation cardiac surgery. Methods Choose 40 cases extracorporeal circulation cardiac surgery patients in our hospital, divide them into control and experimental group randomly, 20 cases in each. Control group was treated with routine blood protection measures only, and experimental group was with autoblood precharging technique based on control group therapy. Record and analyze hematocrit, blood transfusion volume and blood transfusion rate, and patient's postoperative recovery in perioperative period. Results Extracorporeal circulation cardiac surgery was successfully performed for two groups, no deaths and major complications occurred. Erythrocrit value of experimental group was higher than control group, and blood transfusion volume and blood transfusion rate in perioperative period was lower than control group(P<0.05). Conclusion Autoblood precharging technology can reduce excessive hemodilution during extracorporeal circulation effectively, maintain high hematocrit value, reduce blood transfusion volume and blood transfusion rate in perioperative period, and achieve saving blood effect.
