Abstract

PURPOSE: To assess whether snoring is associated with sudden patient movement during local anesthesia with intravenous sedation. METHODS: In this prospective cohort study, patients undergoing ocular surgery with local anesthesia with intravenous sedation were studied. The occurrence or absence of snoring, and whether patient movement was noted were prospectively recorded. Complications that arose from patient movement were also noted. RESULTS: A total of 230 surgical procedures were included in the study. All cases were vitreoretinal surgery cases. During 37 procedures, snoring was noted, and among these, 18 patients (48.6%) moved their head suddenly. In contrast, movement occurred during only 2 of 193 procedures (1.0%) without documented snoring (P < 0.001). Thus, sudden patient head movement was approximately 49 times more prevalent in patients who snored. Continuous infusion propofol was also associated with sudden unexpected head movement (P = 0.0028). No complications as a result of the movement were identified in this study. CONCLUSION: Snoring during local anesthesia with intravenous sedation predicts a high likelihood of sudden patient movement during local anesthesia with intravenous sedation. The use of continuous infusion propofol anesthetic may increase the chance of head movement. Eye surgeons should be aware of these associations to help minimize the risk of complications caused by patient movement.
