摘　　要：Objective To investigate the effects of the topical use of aprotinin on thebasis of comprehensive blood conservations in cardiopulmonary bypass (CPB). Methods In a prospectiveclinical trial, 20 patients were randomly divided into 2 groups. Control group: placebo was usedtopically. Aprotinin group: aprotinin was poured into the pericardial cavity before closure of thesternotomy. Before and 24h after surgery, hemoglobin (Hb), hematocrit (Hct), bleeding time (BT),clotting time (CT) and prothrombin time (PT) were measured. Meanwhile, amounts of the mediastinaldrainage and the hemoglobin loss were observed at 0, 2, 6 and 24h after operation. The samples fromthe mediastinal drainage were also collected to measure D-Dimer (D-D), tissue type plasminogenactivator (t-PA) activity, plasminogen activator inhibitor (PAI) activity and protein C (PC).Results In Aprotinin group, D-D, t-PA activity and PC were significantly reduced, compared withthose in Control group (P<0.05, P<0.05, P<0.01). On the contrary, PAI activity was significantlyincreased, compared with that in Control group. Amounts of the mediastinal drainage and thehemoglobin loss were decreased by 43% and 52%, compared with those in Control group. Conclusion Ourresults suggest that the topical use of aprotinin can have better effects on the basis ofcomprehensive moderate blood conservation.目的:探讨体外循环(CPB)心脏手术中采取综合性血液保护措施的基础上(转流中预充小剂量抑肽酶4～5万kIU/kg,手术失血回输,术后机器余血回输)再局部应用抑肽酶的血液保护效果。方法:体外循环心脏手术病人20例随机分为对照组(C组10例)、局部应用抑肽酶组(A组10例)。检测指标:①D-二聚体(D-D)含量、组织型纤溶酶原激活物(t-PA)活性、组织型纤溶酶原激活物抑制剂(PAI)活性、蛋白c(PC)含量;②纵隔心包引流量、血红蛋白丢失。结果:局部用抑肽酶组引流液中D-D含量、t-PA活性、PC含量均低于对照组(P<0.01、P<0.05、P<0.01).PAI活性高于对照组(P<0.05),术后24小时纵隔心包引流量、血红蛋白丢失量较对照组降低(P<0.05,P<0.01)。结论:在常规采用综合性血液保护措施的基础上,局部应用抑肽酶可收到更佳的血液保护效果。
