摘要 目的评价常规补液与脉搏压变异度指导补液对妇科恶性肿瘤切除术患者容量治疗的效应。方法选择择期行妇科恶性肿瘤切除术患者60例,ASAⅡ级,随机分为2组:对照组即常规补液组(A组,n=30),目标管理补液组即PPV组(B组,n=30)。连续监测心电图、心率、平均动脉压、脉搏压变异度。A组输入液体总量=补偿性扩容量+生理需要量+累计缺失量+继续损失量+第三间隙丢失量。B组根据PPV指导补液,目标值为10%,PPV值升高>13%提示容量不足,于15 min内经静脉输注6%HES 130/0.4 200 ml,如此反复直至PPV<10%停止输注胶体,缓慢静滴晶体液。记录手术时间和术中晶体量、胶体量及尿量,记录各时段的血流动力学情况(BP、HR、CVP、PPV),包括麻醉诱导前Tl,机械通气5 min后T2,打开腹腔时T3,手术结束时T4。于麻醉诱导后即刻和术毕时进行动脉、静脉血气分析,计算氧供指数(DO2I)、氧耗指数(VO2I)和氧摄取率(ERO2)。结果与A组相比,B组总输液量、晶体量减少、胶体量增加、尿量减少,差异有统计学意义(P<0.05);T4时刻,与A组相比,B组的HR降低,差异有统计学意义(P<0.05);T3、T4时刻,与A组相比,B组CVP、PPV差异有统计学意义(P<0.05);手术结束,与A组相比,B组DO2I、VO2I和ERO2均升高,而LAC降低,差异有统计学意义(P<0.05)。结论以PPV为目标导向的容量管理能优化妇科恶性肿瘤切除术患者术中的血流动力学,保证微循环灌注,维持机体氧供需平衡,效果优于经典液体治疗方案。
