A comparison of sleep-disordered respiration in ESRD patients receiving hemodialysis and peritoneal dialysis.

STUDY OBJECTIVE

To compare sleep-disordered respiration in ESRD patients receiving peritoneal dialysis and hemodialysis.

DESIGN

Subjective and objective measures of sleep were recorded in two groups of ESRD patients receiving PD and HD.

SETTING

Tertiary-referral university hospital

PATIENTS AND METHODS

Fifteen PD patients (12 males, 3 females) and 15 HD patients (11 males, 4 females) were studied for two nights in the sleep laboratory.

RESULTS

Ten of the 15 PD patients and 8 of the 15 HD patients reported multiple types of sleep difficulties (NS). In the PD group, seven described substantial difficulty initially going to sleep; ten were troubled by awakenings during the night, while seven suffered from daytime sleepiness. In the HD group, seven described substantial difficulty initially going to sleep; eight were troubled by awakenings during the night, while five experienced day-time sleepiness. No significant difference was observed in total sleep time, intermittent wake time, sleep latency, sleep efficiency, total disordered breathing events, minimum oxygen saturation and periodic leg movements between the PD and HD groups. Sleep apnea was noted in 9 of 15 PD and 8 of 15 HD patients.

CONCLUSIONS

This study indicates that the incidence and severity of sleep apnea is similar in ESRD patients receiving chronic peritoneal dialysis and hemodialysis.
