OBJECTIVE To summarize the experience of extracorporeal circulation ( ECC ) of cardiac operation with video -assisted thoracoscopy. METHODS From Sep. 2008 to Oct. 2010, 29 patients ( 7 males and 22 females ) underwent cardiac operation with video -assisted thoracoscopy in our department. 16 of them underwent atrial septal defect repaire, 12 mitral valve replacement and one mitral valvuloplasty. All cases underwent cardiac operation with ECC and general anaesthesia. The flow of ECC was about to 60 - 80 ml/( kg · min ) under moderate hypothermia ( 28 - 32℃ ). Cold blood cardioplegia ( 20 ml/kg/30min ) was delivered. RESULTS The ECC duration was 50 - 244 ( 122 ± 50 ) min and aortic cross clumping duration was 20 - 137 ( 71 ± 33.2 ) min. All returned spontaneously after cross clamping release, successfully weaned from ECC. All patients recovered well and discharged uneventfully. CONCLUSION For the specificity of cardiac operation with video - assisted thoracoscopy, a reasonable ECC management can make the most of its advantages.%目的 总结电视胸腔镜辅助下心脏手术的体外循环(ECC)管理经验.方法 回顾性分析2008年9月至2010年10月我院29例电视胸腔镜下心脏手术的ECC情况.其中男性7例,女性22例,房间隔缺损修补术16例,二尖瓣置换术12例,二尖瓣整形术1例.手术均在全身麻醉ECC下完成,ECC为中低温(28～32℃)、中高流量[60～80 ml/(kg·min)],心肌保护为4℃(1∶4)冷血心肌保护液,总量为20 ml/(kg·30 min).结果 本组ECC转流时间50～244(122±50)min,主动脉阻断时间20～137(71±33.2)min.所有病例在开放主动脉后心脏均自动复跳,并成功脱离ECC,无术后早期死亡,均顺利治愈出院.结论 针对电视胸腔镜辅助下心脏手术的特殊性给予合理的ECC管理以更好的发挥其优势.
