Methods the object of this study was to select 116 patients with diabetic chronic renal failure during the period from December 2015 to December 2016. The clinical data were analyzed retrospectively, and 2 groups were set up according to the different nursing plans, of which 51 cases of conventional nursing were set as control group, and comprehensive protection was performed. 65 cases of physical education were set as observation group, and two groups were compared with mental state and complications after nursing. Results compared with before nursing, the scores of SDS and SAS in the two groups were significantly lower after nursing, but the decrease of the observation group was better than that of the control group (P<0.05), and the total incidence of complications in the control group was higher than that in the observation group (P<0.05). Conclusion comprehensive nursing for hemodialysis patients with DCRF can effectively alleviate their psychological state and reduce complications, which can be widely applied in clinical practice.
