Nocturnal hemodialysis reducing mortality risk of maintenance hemodialysis patients / 第二军医大学学报

ABSTRACT

Objective To compare the difference of mortality risk between patients undergoing nocturnal hemodialysis (NHD) and conventional hemodialysis (CHD) and to explore the related factors of mortality. Methods The study cohort comprised the maintenance hemodialysis patients receiving either NHD (n=111) or CHD (n=722) in Changzheng Hospital of Second Military Medical University from Feb. 2009 to Feb. 2017. The demographic information, clinical characteristics, survival status, causes of death and laboratory examination indexes were obtained from hemodialysis management system. The urea clearance index (Kt/V), hemoglobin, blood phosphorus concentration and mortality were compared between NHD and CHD patients. The multivariate-adjusted Cox model was used to analyze the mortality risk of all patients. Results Compared with the patients receiving CHD, the proportion of male was more in the NHD group, and the baseline age was younger (P3 years (P<0.05). Conclusion NHD can effectively increase the solute clearance, improve anemia and calcium and phosphate metabolism, and thus reduce the mortality risk of maintenance hemodialysis patients.
