摘要

目的寻找一种简便准确判定血液透析患者干体重的方法。方法选择48例长期血液透析患者，根据干体重的临床标准将患者分达标组（29例），未达标组（19例），每组又按患者血红蛋白水平不等分为a组:HB≥10g/dl；b组:8g/dl≤HB＜10g/dl；c组:HB＜8g/dl三个亚组。使用在线血容量监测仪(BVM)测定所有患者透析开始、透析结束时血液中水含量(BWC)。结果干体重达标组透析开始血液中水含量分别为a：（83.58±1.22）%，b：（84.55±1.37）%，c：（85.87±1.89）%。未达标组透析开始血液中水含量分别为a：（86.78±2.21）%，b：（87.53±3.70）%，c：（88.80±3.90）%。结论透析前血液中水含量与干体重密切相关，可以作为评价血液透析患者干体重是否达标的重要指标。

Abstract

Objective To establish a simple and precise method for evaluating the dry body weight of dialysis patients. Methods Fourty-eight maintenance hemodialysis patients were studied. Twenty-nine of them who reached the clinical standard of dry body weight were divided into group one, the other 19 patients as guoup two. According to the level of hemoglobin (HB),We divided the patients in each gruop into three sub-groups as (HB≥10g/dl), B(8g/dl≤HB＜10g/dl) and c (HB＜8g/dl). The On-Line blood volume monitor (Brm) was applied to test the blood water content (BWC) for all patients at the beginning and the end of dialysis.Results At the beginning of dialysis, the BWC of group one are as follow, A:(83.58±1.22)%，b：(84.55±1.37)%，c：(85.87±1.89)%. The BWC of group two are listed as, a：(86.78±2.21)%，b：(87.53±3.70)%，c：(88.80±3.90)%. Conclusions At the beginning of dialysis,BWC is highly correlative to dry body weight, so it can be regarded as an important factor on estimating whether dry body weight reaches the standard or not.
