Abstract: Objective To compare the effect of spinal anesthesia and general anesthesia(GA) on postoperative sleep quality in elderly patients undergoing hip surgery. Methods In this prospective cohort-based study, patients with hip fracture, aged ≥65 years were divided into 2 groups according to the anesthesia method: combined spinal plus epidural anesthesia(CSEA) group and GA group(n=69 each) from November 2019 to August 2020. All patients received the same perioperative pain management. Subjective sleep quality was assessed by the sleep diaries recording sleep quality, total sleep time, and number of awakenings. The Objective sleep quality was assessed by sleep tracker recording total sleep time(TST), rapid-eye-movement(REM) time, light sleep time and deep sleep time. Numeric Rating Scales(NRS) were used to assess the intensity of postoperative pain. Results Compared with CSEA group, the Sleep Quality Score and deep sleep time were significant lower(P＜0.05), and the number of awakenings(P＜0.05) was significant higher in GA group in the intraday night of surgery. Conclusions Compared with CSEA group, sleep disruption is more severe in the GA group at the intraday night of the patients with hip fracture.
