摘　　要：目的:考察不同指标评估腹膜透析患者容量状态的有效性。方法:收集2009年6月～8月在我院进行腹膜透析的患者139例,以受试者工作特征曲线(ROC)分析原理得到身高和体重标化的细胞外液评价患者容量状态的临界值,并采用χ2检验分析体重标化的细胞外液(extracellular water normalized for weight,ECW/w)、身高标化的细胞外液(extracellularwater normalized for height,ECW/h)、收缩压(systolic blood pressure,SBP)、左室舒张末期直径(left ventricular end-diastolic di-mension,LVEDD)和OH(overhydration)等指标评价容量状态的有效性。结果:由ROC原理得ECW/h和ECW/w评价容量状态的临界值分别为9.04 L/m和0.254 8 L/kg,经χ2检验分析得ECW/h与OH值评价容量状态的有效性相似(P>0.05)。结论:ECW/h可有效评价腹膜透析患者容量状态。Objective：To evaluate the effectiveness of different indicators to assess volume status in patients with peritoneal dialysis. Methods：From June to August,2009.139 peritoneal dialysis patients in our hospital were enrolled.Normalized extracellular water（nECW） was obtained by ROC（receiver operating characteristic） curve to assess the volume status in patients with peritoneal dialysis.The effectiveness of different indicators to assess volume status in patients with peritoneal dialysis was evaluated by chi-square test analysis. Results：The critical value of ECW/h and ECW /w were 9.04 L/m and 0.254 8 L/kg obtained by ROC.ECW/h had the similar effectiveness with OH by chi-square test analysis（P0.05）. Conclusion：ECW/h can effectively evaluate volume status in patients with peritoneal dialysis.
