对52例维持性血透的尿毒症患者,分无症状、心血管并发症、间发性感染以及死亡病人等四组,分别观察血透对中、小分子物质的清除状态及与临床中毒症状之间的关系。结果血透前四组中、小分子物质均高于正常人水平(P<0.01);各组的小分子物质清除理想,中分子物质清除差;血透后死亡组中分子物质较血透前高,与其它三组相比有显著差异;血透前、后三组小分子物质均高于无症状组。 52 cases of maintenance hemodialysis patients with uremia, asymptomatic, cardiovascular complications, the incidence of infection and death of patients in four groups were observed hemodialysis on the removal of small and medium-sized substances and clinical symptoms of poisoning The relationship between. Results The contents of small and medium molecules in the first four groups of hemodialysis were all higher than those in normal subjects (P <0.01). The small molecules in each group were well cleared and the middle molecules were poorly cleared. In the hemodialysis group, High, compared with the other three groups were significantly different; hemodialysis before and after three small molecules were higher than asymptomatic group.
