代谢性酸中毒是慢性肾脏病非常常见的并发症。纠正代谢性酸中毒是防治慢性肾脏病多种系统性并发症的基础。血液透析患者酸碱平衡的维持取决于机体净酸产生量、从透析液中获取的碱总量、透析时长以及残余肾功能等多种因素。本文主要就透析液碳酸氢盐浓度对透析患者预后的影响进行综述。

Metabolic acidosis is a common complication in chronic kidney disease patients. It is funda mental for the treatment of multiple systemic complications of chronic kidney disease to correction of metabolic acidosis. For the patients undergoing hemodialysis, the acid-base balance depends on many factors, including body net acid generation, the total amount of the alkali obtained from the dialysate,duration of the interdialytic period,and residual renal function.This paper will mainly discuss the effect of dialysate bicarbonate concentration on prognosis in dialysis patients.
