摘要
目的:探讨用动脉轮廓曲线连续心排量(picco)技术测得的血管肺水含量指数对危重病患者预后的评估价值。方法:回顾性分析76例行picco检测的ICU患者临床资料,根据预后分为死亡组与存活组,分别记录0 h、24 h、72 h血流动力学参数,比较血管外肺水含量指数(EVLWI)在各时间点是否有差异。根据入ICU时EVLWI≤7.0,≥7.0,≥12.0,≥15.0分为四组,分别计算其死亡率。结果:0时死亡组的EVLWI明显高于存活组(P<0.05),24 h、72 h死亡组与存活组的EVWLI相比较无明显差异,P>0.05。入ICU时EVLWI≤7.0,>7.0,≥12.0,≥15.0的死亡率分别为21%,50%,69%,88%。结论:早期EVLWI可以作为危重病患者预后的评估指标之一,随EVLWI的升高患者的死亡率升高。
Objective：To investigate the prognostic value of extravascular lung water index （EVLWI） in critically ill patients using pulse index continuous cardiac out put （picco） technology. Methods： The clinical data of 76 cases monitored by picco were analyzed retrospectively.The cases were divided into death group and survival group according to the prognosis. The hemodynamie parameters in 0 h, 24 hs,72 hs were recorded and EVLWI were compared between the two group. According to EVLWI after in the ICU, they were divided into four groups （EVLWI ≤7.0, 〉 7.0, ≥12.0, ≥ 15.0）, than calculated the four groups of mortality rates separately. Results： EVLWI in death group was higher than that in survival group at Oh time, the EVLWI was significant difference between the death group and survival group at 24 hs and 72 hs（P〉0.05）. After in the ICU, the mortality of the group of EVLWI ≤7.0,〉7.0, ≥ 12.0,≥ 15.0 were 21%, 50%, 69%, 88% separately. Conclusion： The early EVLWI of critically ill patients may take one of seriously prognostic indicators, along with EVLWI ascension patient＇s mortality rate ascension.
