摘要 目的探讨急诊冠状动脉旁路移植术(CABG)的有效体外循环(ECC)管理方法和效果。方法本组44例均在全麻ECC下行急诊CABG。用膜式氧合器,非搏动灌注,流量2.2~2.6L/(min.m2),灌注压力维持在60~80mmHg。采用浅低温ECC技术,ECC中Hct0.23~0.27。阻断升主动脉后间断灌注4:1温血停搏液。18例应用超滤或改良超滤。结果 ECC平均时间(118.7±30.5)min。主动脉阻断时间(69.2±20.6)min。平均辅助时间(44.4±17.5)min。39例开放升主动脉时自动复跳;5例开放后室颤,经lOWS除颤后复跳。本组未见并发症发生,均康复出院。结论温血心肌保护液灌注有利于术中保护心肌,浅低温和改良超滤技术可提高疗效,合理的ECC管理是急诊CABG成功的重要保证。
