Background: The objective of the study was to determine the prevalence of sleep complaints and of sleep disordered breathing (SDB) in hemodialysis patients not selected for sleep complaints and to determine the effect of hemodialysis on SDB. The feasibility of home recording of sleep related respiration in these patients was also studied.
Methods: The patients completed a questionnaire and parameters of SDB were examined in the home setting on nights following dialysis and nights following no dialysis with the Edentrace II Recording System.
Results: Six (46%) of 13 patients had sleep complaints. Symptoms suggestive for sleep apnea syndrome were found in four (31%) of these 13 patients. In three (75%) of these four patients SDB was found. Sleep related respiration was monitored in 15 patients. Registrations satisfactory for interpretation were obtained in all patients. SDB was observed in five (33%) of these 15 patients. There were no significant differences in parameters of SDB between nights following dialysis and nights following no dialysis.
Conclusions: Home recording of sleep related respiration in hemodialysis patients is feasible. Sleep complaints and SDB are common in these patients. No clinically significant differences in SDB were found between nights following dialysis and nights following no dialysis.
