摘要 目的评价每搏量变异在预测神经外科分布性休克患者液体反应中的临床价值。方法 22例神经外科分布性休克患者进行容量负荷试验。分别记录扩容前后患者中心静脉压(central venous pressure,CVP)、全身血管阻力指数(systemic vascu-lar resistance index,SVRI)、心率(heart rate,HR)、平均动脉压(mean arterial pressure,MAP)、每搏量变异(stroke volume variation,SVV)以及每搏量指数(stroke volume index,SVI)等指标变化情况。结果 l6例患者为容量反应性阳性,6例为容量反应性阴性。容量负荷后所有患者CVP、SVI等指标显著性增加(P<0.05),而SVV、SVRI等指标显著性降低(P<0.05)。容量反应性阳性的患者,其容量负荷前的SVV明显高于容量反应性阴性的患者(P<0.05)。SVV判断容量反应性的灵敏度为80%,特异度为100%。结论 SVV可准确预测神经外科分布性休克患者术中的容量反应性。
