血清白蛋白水平对血液透析低血压发生的影响

目的了解血浆白蛋白水平对血液透析时低血压发生率的影响。方法按血清白蛋白水平分为三组:血清白蛋白>35g/L组、25-35g/L组和<25g/L组,观察三组在血透期间低血压的发生率。结果随着血清白蛋白水平的下降,低血压的发生率呈升高趋势,三组的发生率分别为4.8%,6.4%,25.7%,三组间有显著性差异(P<0.01)。结论血浆白蛋白在维持血透期间的血压起着重要的作用,低白蛋白血症,尤其白蛋白<25g/L时,易发生低血压,在拟定超滤方案时应充分考虑这一因素。

Influence of serum albumin leves on incidence of hypotension of patients during hemodialysis

Objective To realize the influence of serum albumin levels on incidence of hypotension of patients during hemodialysis.Methods 52 patients were divided into three groups according to serum albumin levels(>35g/L,25-35g/L,<25g/L),then incidence rate of hypotension during hemodialysis was observed.Results As serum albumin level fallen,the incidence rate of hypotension showed higher trend,the incidence rate of three groups were 4.8%,6.3% and 25.7% respectively,there was no significantly statistical difference between>35g/L group and 25-35g/L group(P>0.05).The incidence rate of hypotension both>35g/L group and 25-35g/L group were higher than <25g/L group(P<0.001).Conclusion Serum albumin could play an important role of keeping blood pressure during hemodialysis;hypotension can occur easily during low albumin level,especialy<25g/L.This factor should be considered at working out ultrafiltration plan.
