本文主要研究钠排泄分数(FE_(Na)),尿钠浓度(U_(Na)),尿渗量(Uosm)和(尿/血浆)肌酐(U/p Cr)比值在87个急性肾衰(ARF)病人中的诊断效率,并互相之间进行比较,通过鉴别分析,发现在87个病人中,有86个正确的分类诊断是采用FE_(Na)。而以Uosm,U_(Na),和U/P Cr的正确率仅分别为46、60和65。故FE_(Na)被人们视为鉴别ARF极为有效而无害的检查。材料和方法对87个ARF的成年病人进行过5年以上的预期性研究。前24小时接受利尿治疗者除外。以后临床上对
In this paper, we studied the relationship between the ratio of sodium excretion (FE Na), urinary sodium (U Na), urinary osmolality (Uosm) and urinary to plasma creatinine (U / p Cr) ARF), and compared them with each other. By differential analysis, 86 out of 87 patients were diagnosed correctly using FE Na. The correct rates for Uosm, U_ (Na), and U / P Cr are only 46, 60 and 65, respectively. Therefore, FE_ (Na) is regarded as the most effective and harmless examination for identifying ARF. MATERIALS AND METHODS A prospective study of 87 ARF adult patients over 5 years. Except for the first 24 hours of diuretic treatment. After clinical right
