摘要目的探讨被动抬腿试验对行早期液体复苏的感染性休克患者的容量反应性评价。方法选择48例感染性休克患者,根据液体复苏前的被动抬腿(PLR)试验将患者分为有反应组(PLR试验阳性,n=20)及无反应组(PLR试验阴性,n=28)。监测两组患者复苏前、复苏结束后即刻、复苏结束后2h、复苏结束后6h的血管外肺水指数(EVLWI)、氧合指数(PaO2/FiO2)和血流动力学等指标的变化。结果与复苏前比较,两组患者液体复苏结束后即刻、2h、6h的胸腔内血容量指数(ITBVI)均有增加(P<0.01);而各时间点PaO2/FiO2与复苏前相比,差异均无统计学意义(P>0.05)。与复苏前相比,有反应组患者的CVP仅在复苏结束后6h有增加(P<0.01),无反应组患者的CVP于复苏结束后2h、6h均有增加(P<0.01)。与复苏前比较,两组患者复苏结束后即刻、2h、6h的EVLWI均有增加(P<0.05),无反应组患者增加更明显(P<0.05)。结论 PLR试验可有效评估行早期液体复苏的感染性休克患者的容量反应性。
