摘要 目的探讨每搏量变异(SVV)在分布性休克患者容量治疗中的价值。方法选取40例确诊为分布性休克的患者均进行容量负荷试验,并同时为本组患者置入中心静脉导管及股动脉导管,连接PICCO监测仪,通过经肺热稀释法及脉搏轮廓分析法,进行SVV、GEDV、CVP、SI等参数监测,观察患者容量负荷试验前后血液动力学变化,及SVV、GEDV、CVP与△SI的相关性。结果40例患者中18例对容量负荷试验有反应,22例无反应,两组患者年龄、性别、APACHE II、呼气末正压及氧合指数均无显著差异,两组患者容量负荷前后MAP、CVP及GEDV无显著差异,有反应组容量负荷试验前后SVV分别为17.4±6.8%,12.3±4.8%,无反应组容量负荷试验前后SVV分别为9.7±3.8%,8.7±3.4%,差异有统计学意义(P<0.05)。容量负荷试验前SVV与△SVV有明显相关性(r=1.125),SVV与△SI明显相关(r=1.208),CVP与△SI有一定相关性(r=0.432),GEDV与△SI有一定相关性(r=0.325),SVV与△SI的相关性优于其他两者。结论通过PICCO技术监测分布性休克患者的SVV对分布性休克患者容量反应性具有更好的预测价值,可作为指导病人容量治疗的依据。
