上消化道出血病例检测血浆非蛋白氮(NPN)和尿素氮(BUN)以估计患者出血程度和肾功能已有多年。本文通过临床资料总结,重点讨论估计出血程度的意义。一、临床资料 1982年1月～1986年7月内科住院上消化道出血病例,男144例,女52例,共196例。患者入院后第2天空腹取血,以常规方法测定的NPN和BUN数值为依据,作下列比较。 1.NPN与BUN比较。检测NPN163例,血浆中浓度20.8～68.4mg/dl,平均值34mg/dl,超过正常值者(>35mg/dl,下同)60例占36.8％;检测BUN33例,血浆中浓度10.8～35.2mg/dl,平均值19.95mg/dl,超过正常者(>20mg/dl,下同)15例占45.45％.NPN与BUN两者增加率,经X~2测验无显著性差异
Patients with upper gastrointestinal bleeding have been tested for plasma non-protein nitrogen (NPN) and urea nitrogen (BUN) for years to assess the extent of bleeding and renal function in patients. This paper summarizes the clinical data, focusing on the significance of estimating the degree of bleeding. First, the clinical data January 1982 ~ July 1986 Department of Internal Medicine upper gastrointestinal bleeding, 144 cases of male and female 52 cases, a total of 196 cases. Fasting blood was taken on the second day after admission to the patients and was based on the NPN and BUN values determined by routine methods and was compared as follows. 1.NPN and BUN comparison. Detection of NPN163 cases, the plasma concentration of 20.8 ~ 68.4mg / dl, the average of 34mg / dl, more than the normal value (> 35mg / dl, the same below) 60 cases accounted for 36.8%; detected BUN 33 cases, plasma concentrations of 10.8 ~ 35.2mg / dl, the average 19.95mg / dl, more than normal (> 20mg / dl, the same below) 15 cases accounted for 45.45% .NPN and BUN increased rate of both, no significant difference by X ~ 2 test
