摘要 目的:探讨七氟醚诱导麻醉下行腹腔镜胆囊切除术对老年患者左心功能的影响。方法:选择全麻下行腹腔镜胆囊切除术老年患者30例,ASAⅠ或Ⅱ级,采用O_2流量2~3L/min,吸入6%七氟醚,监测肺泡气最低有效浓度(MAC)达到1.8~2.0值后,给予芬太尼2~3μg/kg,肌松剂苯磺酸顺阿曲库铵0.1~0.15mg/kg,3min后行气管插管术;使用组织多普勒射频技术采集麻醉诱导前(T_0),气管插管前(T_1)、气管插管后30s(T_2)、气管插管后20 min(T_3)、拔出导管后20 min(T_4),心脏每搏量(SV)、射血分数(EF)、心输出量(CO)、心肌活动指数(Tei),监测心率(HR)、动脉压(MAP)、外周血氧饱和度(SpO_2),并记录麻醉过程中不良反应发生情况。结果:与T_0时比较T_(1~3)时SV、EF、Tei指数增加(P<0.05),CO、MAP和HR变化差异无统计学意义,无不良反应发生。结论:七氟醚麻醉诱导下对老年患者行腹腔镜胆囊切除术,对左心功能有一定程度上的抑制,但对循环系统影响不明显。
