Abstract

AbstractAimsAlthough it has been reported that general anesthesia affect the perioperative sleep cycle, no studies have yet evaluated how general anesthesia affects dentally disabled patients. In this study, we investigated the alteration of perioperative sleep cycles in dentally disabled patients receiving dental treatment under general anesthesia.Subjects and methodsThe study included 16 patients receiving dental procedures under general anesthesia. Using a sleep monitoring mat, the patients' sleep cycles were measured at home from 5 days before the scheduled surgery date until 5 days after discharge following general anesthesia. The change in all the variables of sleep cycles were analyzed in comparison to the value in preoperative period. Daily differences in these variables were assessed for statistical analysis.ResultsThe percentage of deep sleep (Stages 3 and 4) decreased significantly on postoperative day 1, and the percentage of light sleep increased. Furthermore, sleep cycles were significantly extended on postoperative day 1.ConclusionThe percentage of deep sleep decreased significantly on postoperative day 1 while the percentage of light sleep increased. Sleep cycles were also significantly extended on postoperative day 1. These results reveal that the sleep cycle is somehow affected on the first day following general anesthesia.
