Does Intraoperative Sedation by Dexmedetomidine Prevent Postoperative Sleep Disorder?：A Retrospective Study

Abstract

In this study, we retrospectively investigated whether or not intraoperative sedation by dexmedetomidine（DEX）improved sleep disorders after urological surgery. Patients were classified into two groups based on the sedatives used in combination with spinal anesthesia：DEX group（n=73）and midazolam（MDZ）group（n=54）. The number of patients who used sleep-inducing drugs on the day of surgery in the DEX group（n=5）was significantly less than that in the MDZ group（n=13）. The result suggests that DEX could reduce the postoperative sleep disorders even though it is used only during surgery.
