摘要 目的观察屈氏位和反屈氏位对腹腔镜胃肠道肿瘤手术FloTrac/Vigileo系统的影响。方法按随机数字表法选择腹腔镜胃肠肿瘤手术患者80例,分为屈氏位组(A组)和反屈氏位组(B组),每组40例。在气管插管后,机械通气状态下、血流动力学平稳、容量控制模式、潮气量为8 mL/kg、呼吸频率13~15次/min,记录插管后平卧位(T0)、气腹即刻(T1)、气腹后改变体位前(T2)、改变体位后1 min(T3)、5 min(T4)、10 min(T5)、20 min(T6)、手术结束(T7)、去气腹平卧位(T8)各时点平均动脉压(MAP)、心指数(CI)、每搏量指数(SVI)、每搏量(SV)、每搏量变异度(SVV)、心输出量(CO)的数值并行相关分析。结果两组SV、CO比较,B组在T3、T4、T5时点低于A组(P<0.05);组内比较,A、B两组CO在T8时点高于T0(P<0.05),B组SV在T3、T4、T5显著低于T0(P<0.05)。SVV组内比较,A组在T8低于T0(P<0.05),其余各时点与T0比较差异均无统计学意义(P>0.05),B组在T3、T4、T5、T6高于T0(P<0.05),T8低于T0(P<0.05);组间比较,A组患者T3、T4、T5、T6明显低于B组患者。结论腔镜胃肠道肿瘤切除手术患者术中不同的体位改变,SVV、SV、CO均有不同的变化趋势,其容量状况需综合评估。
