WANG Yanhui,LIU Yi,ZHENG Chenfei, et al. Analysis of death causes in patients with maintenance hemodialysis in Wenzhou areas[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2014, 44(4): 296-299.
Abstract：Objective: To analyze the death causes and the characteristics of the maintenance hemodialysis (MHD) patients died in 18 hospitals of Wenzhou areas of China from January 2010 to December 2012. Methods: The causes of death in patients with MHD for more than 3 months were retrospectively analyzed. These patients, were divided into 3 groups abased on age: young group (20 to 44 years old), middle age group (45 to 64 years old), elderly group (≥65 years old). Dialysis age, end stage renal disease (ESRD) causes and the biochemistry indexes at the beginning and within one year prior to death were analyzed among the three groups. Results: Of the 269 death cases, 166 cases were male and 103 female, with the mean age of 66.9±13.7 years old (21 to 93 years old). 20 cases were in young group, 80 in middle age group and 169 in elderly group. Diabetes was major ESRD cause in all cases. Cerebral vascular diseases and cardiovascular diseases were main death causes among three groups, and there was no significant difference among them. Systemic failure was the secondary death cause in elderly group. Serum creatinine (Cr) and blood urea nitrogen (BUN) at the beginning and within one year prior to death in elderly group were lower than that in the other two groups, the serum albumin was the same as sCr and BUN within one year prior to death. Conclusions: Most of the death cases with MHD in this study are older than 65 years of age in Wenzhou area. Diabetes is a major ESRD cause in all cases. Cerebral vascular diseases are the first death causes and cardiovascular diseases are the second among three groups, Systemic failure as death cause in elderly group is more common. Nutritional status in elderly patients is worse than that in young and middle age patients.
