摘要 目的评价每搏量变异度(SVV)监测活体肝移植手术患者血容量变化的准确性。方法择期行活体肝移植手术患者23例,麻醉诱导后行气管插管,气管插管后15 min,以0.4 mL/(kg.min)的速率静脉输注6%羟乙基淀粉8 mL/kg。于输注前即刻和输注后3 min记录MAP、HR、CVP、心脏指数(CI)和SVV,计算SVV和CI的变化率(ΔSVV和ΔCI)。以ΔCI≥15%为扩容有效标准,绘制SVV判断血容量变化的ROC曲线,计算曲线下面积(AUC)及其95%可信区间(95%CI)。结果与治疗前即刻比较,治疗结束后3 min MAP、CVP、CI升高而SVV下降(P<0.05或<0.01)。ROC曲线分析结果显示,SVV监测血容量变化的AUC为0.865(95%CI 0.685~1.000),诊断阈值为9.5%,灵敏度为84.6%,特异度为80%。结论 SVV监测活体肝移植手术患者血容量变化准确性良好,可用于指导容量治疗。
