Acute preoperative plateletpheresis (APP), cell salvage (CS) technique, and the use of aprotinin have been individually reported to be effective in reducing blood loss and blood component transfusion while improving hematological profiles in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). In this prospective randomized clinical study, the efficacy of these combined approaches on reducing blood loss and transfusion requirements was evaluated. Seventy patients undergoing primary coronary artery bypass grafting (CABG) were randomly divided into four groups: a control group (group I, n = 10) did not receive any of the previously mentioned approaches. An APP and CS group (group II, n = 20) experienced APP in which preoperative platelet-rich plasma was collected and reinfused after reversal of heparin, along with the cell salvage technique throughout surgery. The third group (group III, n = 22) received aprotinin in which 5,000,000 KIU Trasylol was applied during surgery, and a combination group (group IV, n = 18) was treated with all three approaches, i.e., APP, CS, and aprotinin. Compared with group I (896+/-278 mL), the postoperative total blood loss was significantly reduced in groups II, III, and IV (468+/-136, 388+/-122, 202+/-81 mL, respectively, p < 0.05). The requirements of packed red blood cells in the three approached groups (153+/-63, 105+/-178, 0+/-0 mL, respectively) also were reduced when compared with group I (343+/-118 mL, p < 0.05). In group I, six patients (6/10) received fresh-frozen plasma and three patients (3/10) received platelet transfusion, whereas no patients in the other three groups required fresh-frozen plasma and platelet. In conclusion, both plateletpheresis concomitant with cell salvage and aprotinin contribute to the improvement of postoperative hemostasis, and the combination of these two approaches could minimize postoperative blood loss and requirement.
术前急性血小板去除术(APP)、细胞回收(CS)技术以及抑肽酶的使用,已分别被报道在接受体外循环(CPB)心脏手术的患者中,对于减少失血和血液成分输注、改善血液学指标有效。在这项前瞻性随机临床研究中,评估了这些联合方法在减少失血和输血需求方面的疗效。70例行初次冠状动脉旁路移植术(CABG)的患者被随机分为四组:对照组(I组,n = 10)未接受上述任何一种方法。APP和CS组(II组,n = 20)接受APP,即术前采集富含血小板血浆,肝素逆转后回输,同时在整个手术过程中采用细胞回收技术。第三组(III组,n = 22)接受抑肽酶,术中应用5000000 KIU抑肽酶,联合组(IV组,n = 18)接受所有三种方法,即APP、CS和抑肽酶。与I组(896±278 mL)相比,II、III和IV组术后总失血量显著减少(分别为468±136、388±122、202±81 mL,p < 0.05)。与I组(343±118 mL,p < 0.05)相比,三种治疗组的浓缩红细胞需求量(分别为153±63、105±178、0±0 mL)也有所减少。在I组中,6例患者(6/10)接受了新鲜冰冻血浆,3例患者(3/10)接受了血小板输注,而其他三组中无患者需要新鲜冰冻血浆和血小板。总之,血小板去除术与细胞回收术联合以及抑肽酶均有助于改善术后止血,这两种方法联合可使术后失血量和需求量降至最低。
