老年腹膜透析患者低钾血症的危险因素分析

目的调查老年腹膜透析患者出现低钾血症的状况,并分析其可能的危险因素。方法采用横断面研究。184例腹膜透析患者,其中老年组患者100例。调查患者的一般资料、透析状况、血清钾水平、饮食钾摄入量、经尿和腹膜透析液钾丢失量及合并症发生情况。结果老年组腹膜透析患者低钾血症的发生率为27.0%,血钾水平与腹膜透析剂量呈负相关（r=-0.257,P=0.021）,腹膜透析剂量是该组患者出现低钾血症唯一独立性影响因素（P=0.009）。结论腹膜透析剂量与老年腹膜透析患者发生低钾血症有关。

Analysis of Risk Factors of Hypokalemia in Elder Peritoneal Dialysis Patients

Objective Discussion hypokalemia situation in elderly peritoneal dialysis (PD) patients,and the possible risks for hypokalemia in these patients. Methods Cross-sectional study. 184 cases of PD patients were involved and 100 cases were elderly patients. The general information of patients, serum potassium levels, level of potassium, dietary intake of potassium, loss of potassium from urine and PD fluid, and occurrence of complications had been investigated. Results The incidence of hypokalemia in old age group PD patients was 27.0%. The level of potassium and PD dose was negatively correlated (r=-0.257, p=0.021). The dose of PD patients was the only independence affects factors to hypokalemia (p=0.009). Conclusion Hypokalemia in the elderly PD patients was related to PD dose.
