目的：了解经持续不卧床腹膜透析CAPD 治疗的糖尿病肾病患者的临床特点，以指导治疗。方法：收集经CAPD治疗的61例糖尿病肾病患者与非透析治疗的42例糖尿病肾病患者的临床资料进行分析，比较他们低血糖、低血钾的发生率及其诱因、症状等方面的特点。结果：CAPD治疗组低血糖、低血钾发生率分别为36％、48％,较非透析治疗组的17％、29％高（P ＜0．05） 。饮食减少是CAPD治疗组发生低血糖、低血钾的主要原因，而非透析组的低血糖、低血钾则主要由胰岛素使用不当及腹泻引起。CAPD治疗组症状往往不典型。结论：经CAPD治疗的糖尿病肾病病人低血糖、低血钾的发生率、诱因、症状均不同于非透析治疗病人，治疗时应区别对待。
Objective: To understand the clinical features of patients with diabetic nephropathy treated with continuous peritoneal dialysis CAPD to guide the treatment. Methods: The clinical data of 61 patients with diabetic nephropathy treated by CAPD and 42 patients with diabetic nephropathy treated by non-dialysis were collected. The incidence of hypoglycemia, hypokalemia and its causes and symptoms were compared. Results: The incidences of hypoglycemia and hypokalemia in CAPD group were 36% and 48%, respectively, which were higher than those in non-dialysis group (17% and 29%, respectively) (P <0.05). Diet reduction is the main cause of hypoglycemia and hypokalemia occurred in CAPD treatment group, rather than hypoglycemia in the dialysis group, hypokalemia is mainly caused by improper use of insulin and diarrhea. Symptoms of CAPD treatment are often not typical. Conclusion: The incidence of hypoglycemia, hypokalemia, triggers and symptoms of patients with diabetic nephropathy treated by CAPD are different from those of non-dialysis patients. Treatment should be treated differently.
