ObjectiveTo explore the occurrence and its related influencing factors of hypokalemia in patients with continuous ambulatory peritoneal dialysis(CAPD). MethodsA clinical data of 86 patients with uremia who carried out continuous ambulatory peritoneal dialysis treatment were retrospectively analyzed. ResultsOf all the 86 cases, there were 25 cases with hypokalemia (29.1%), including 2 out of 10 cases with hypertensive nephropathy (20.0%), 12 out of 31 cases with diabetic nephropathy (38.7%), 10 out of 38 cases with chronic glomerular nephropathy (26.3%), and 1 out of 4 cases with gouty nephropathy (25.0%). There was no significant difference in age, serum creatinine (Scr), blood urea nitrogen (BUN), hemoglobin (Hb), blood phosphorus, serum albumin (ALB), and hypersensitive c-reactive protein (hs-CRP) between hypokalemia group and non-hypokalemia group. Multivariate non-conditional logistic regression analysis showed that the incidence of hypokalemia was positively correlated with blood potassium, phosphorus, serum creatinine (Scr), blood urea nitrogen (BUN), hemoglobin (Hb), serum albumin, hypersensitive c-reactive protein (hs-CRP), and was negatively correlated with age. ConclusionsPeritoneal dialysis patients has a higher incidence of hypokalemia，specially for CAPD patients with diabetic nephropathy. Serum potassium is closely related to age and nutritional status. Finding and correcting hypokalemia timely can improve the quality of life and the prognosis of CAPD patients.
