摘要：目的 探讨体外循环(CPB)术中发生冷凝集试验阳性的处理经验。方法 采用最适宜的温度(鼻咽温31.5℃~32.5℃，肛温34℃~35℃)，常温高钾停跳液，CPB大剂量抑肽酶和皮质激素的应用及激活全血凝血时间(ACT)的严格监测等等。结果 术中阻断主动脉65min，心脏自动复跳，术后无中枢神经系统并发症及血红蛋白尿。结论 对CPB术中发生冷凝集试验阳性的病人采取综合性的防救措施可以有效的防止红细胞凝集、溶血等不良反应，确保手术安全。

    Abstract: OBJECTIVE To report the experincein treating a case of positive cold agglutination test during cardiopulmonary bypass (CPB). METHODS Adopting the most appropriate temperature (nasopharyngeal temperature 31.5℃～32.5℃, anal temperature 34℃～35℃). Hyperkalemia cardioplegia solution at room temperature, large doses of aprotinin and cortin, during CPB and moniting closely for ACT.RESULTS Aorta was clamped for 65 min. The heart beat recoverd spontmandly. There was no CNS complication or haematuria after the operation CONCLUSION Adopting maltiple measures in cold agglutination test positive patientsduring CPB coued effectively prevent agglutination of red blood and haemolysis, so warrant operative success. ......
