Abstract:

Objective To evaluate the impact of high flow dialysis on sleep quality in maintenance hemodialysis (MHD) patients and to analyze related influencing factors. Methods Eighty two MHD patients who met inclusion criteria at Shanghai Junkang Hospital from October 2023 to March 2024 were enrolled and randomized into two groups (n=41 each) using a random number table. The control group received low flow hemodialysis (blood flow 250-300 ml/min),and the observation group received high flow dialysis (blood flow 300-350 ml/min). The clinical baseline data,sleep quality,metabolic function and renal function before and after treatment were compared between the two groups. Results Baseline characteristics (sex,age,body mass index[BMI],marital status,education level,primary disease,and dialysis vintage) did not differ significantly between groups (P>0.05). Pre-treatment total PSQI and its seven domain scores were similar between groups (P>0.05). Post-treatment,PSQI total and domain scores decreased in both groups versus baseline,with greater reductions in the observation group compared with the control group (P<0.05). Baseline metabolic parameters did not differ significantly between groups (P>0.05). Post-treatment,levels of serum uric acid,total cholesterol,low density lipoprotein-cholesterol(LDL-C),and triglycerides remained comparable between groups (P>0.05). Both groups experienced decreases in leptin and serum uric acid and increases in high density lipoprotein-cholesterol (HDL-C) (P<0.05); the observation group showed significantly lower leptin and higher HDL-C than the control group (P<0.05). Renal function markers were also comparable at baseline (serum creatinine,blood urea nitrogen [BUN],estimated glomerular filtration rate[eGFR],β2 microglobulin; P>0.05). After treatment,serum creatinine,BUN,and β2 microglobulin declined in both groups,with greater reductions in the observation group (P<0.05). eGFR increased in both groups versus baseline,and the increase was significantly larger in the observation group (P<0.05). Conclusion Compared with low flow dialysis,high flow dialysis was associated with greater improvement in sleep quality,metabolic parameters,and renal function in MHD patients.
