【摘要】 目的回顾性总结92例体重为10 kg以下婴幼儿的体外循环(CPB)管理体会。方法对我院92例体重10 kg以下婴幼儿先心病手术的临床资料(年龄、性别、体重、手术类型)及CPB方法(CPB设备、预充液成分、CPB时间、升主动脉阻断时间等)做回顾性分析。结果全组病例CPB时间16-223 min,升主动脉阻断时间0-108 min。92例均顺利脱机,5例术后死亡。结论婴幼儿CPB需性能稳定的心肺机及膜式氧合器,尽可能减少预充量,合理的预充,良好的心肺保护,结合超滤技术,可提高手术成功率。更多还原

【Abstract】 Objective To summary the cardiopulmonary bypass(CPB) management of 92 infants less than 10 kg.Methods The clinical data,including age,sex,body weight,operation type,and CPB conditions,such as equipment,prime composition,duration of CPB,and cross-clamping time of ascending aorta were retrospectively analyzed in 92 infants weighing less than 10 kg and undergoing congenital heart diseases(CHD) operation. Results The CPB duration ranged from 16 to 223 min,and the ascending aorta clamp time was 0-108 min.All the infants were successfully weared from the machine,and 5 died after operation.Conclution High-quality devices are needed.The prime volume should be minimized to the greatest extent,reasonable priming,good myocardial protection and pulmonary preservation,espically ultrafiltration technique should be used to enhance success rate of operation.更多还原
