post-dialysis fatigue is one of the concerns in recent years. The time of fatigue recovery can be used to predict the hospitalization rate and mortality rate. At the same time, there are few reports on the relationship between maintenance hemodialysis (MHD) and protein energy consumption (PEW). The purpose of this study is to investigate the status of fatigue in MHD patients, analyze the factors affecting fatigue and its correlation with PEW, and provide possible effective interventions.


346 MHD patients in our blood purification center were selected. MHD patients were assessed with self-made general data questionnaire, international standard fatigue assessment scale (FAI) and subjective comprehensive nutrition assessment (SGA), and their blood routine and biochemical results were collected for statistical analysis


More than half of patients claimed to experience post-dialysis fatigue.Time to recover from hemodialysis(TIRD) was different: the interquartile range time was 2.00(0.00, 3.00) hours.In the study, 30.1% patients reported no fatigue after hemodialysis. Recovery time in 30.5%% patients was more than 30 minutes to 2 hours,26.1% was 3 to 4 hours, 12.3% was 5 to 12 hours,1.0% patients took longer time to recover from a dialysis session. According to the recovery time, these patients were divided into three groups. Among the three groups, SGA score,the ultrafiltration,the serum sodium and bicarbonate level after dialysis showed significant difference. It was showed by the unconditional logistic regression analysis that high SGA(OR=1.312,95%CI 1.163-1.481), scoreultrafiltration (OR=2.15,95%CI 1.24-3.41) and serum sodium (OR=0.83,95%CI 0.71-0.98) were associated of TIRD.


The incidence of post-dialysis fatigue in MHD patients is high. Medical staff should pay attention to the nutritional status of MHD patients, control their weight growth, and maintain the stability of electrolyte and bicarbonate levels such as serum sodium.
