Objective:To investigate the feasibility of reducing the amount of blood transfusion in the perioperative period of cardiac surgery. Methods: A total of 104 patients undergoing aortic or mitral valve operations were randomly divided into 2 groups: study group(n = 52) and control group (n = 52). Integrated blood conservation measures were applied to the study group in the aspect of anesthesia, cardiopulmonary bypass, surgery and post-operation treatment. Those measures were not applied to the control group. Results: Thirty-six patients in the study group and 19 patients in the control group did not need blood transfusion during the perioperative period. The average amount of blood transfusion in the study group was 302. 9 mL, while that in the control group was 538. 9 mL. There was statistically significant difference in the rate of blood transfusion between the two groups(P＜0. 05). Conclusions: A lower rate of blood transfusion and a smaller amount of blood transfusion can be realized effectively by applying integrated blood conservation strategy and new transfusion criteria during the perioperative period of cardiac surgery.%目的:探讨采用综合省血方法降低心脏手术围术期用血量的可行性和方法.方法:将104例接受心脏单瓣膜手术的患者随机分为两组:研究组(n=52)和对照组(n=52).对研究组的患者采取综合措施,通过麻醉、体外循环、手术、术后处理等方面的措施以减少其围术期的输血率；对对照组的患者则不采取这些措施.结果:研究组36例未输血,输血率30.8％,平均用血量302.9 mL；对照组19例未输血,输血率63.5％,平均用血量538.9 mL;两组患者输血率的差异有统计学意义(P＜0.05).结论:应用综合省血方法和严格的输血标准,能有效降低心脏手术围术期的输血率,并减少手术用血量.
