PurposeTo study methods and adverse events of postoperative, sedated suture adjustment after strabismus surgery in the post-anesthesia care unit (PACU).MethodsWe reviewed the postoperative experience of all children ≤18 years of age undergoing adjustable suture strabismus surgery at Boston Children's Hospital over a 3-year period. Time in the hospital, adverse events, and surgical outcomes were reviewed to evaluate safety and healthcare resource utilization.ResultsOf 356 patients, 113 required suture adjustment in the PACU, including 24 adjusted while awake and 89 adjusted under sedation. For sedation, sequential boluses of propofol were administered until adjustment was complete. Complete data from the sedated adjustment was available in 76 patients. The median initial bolus was 30 mg; the median total propofol rate was 273 mcg/kg/min. Twelve patients (16%) required only a single bolus of propofol. Of remaining 64 patients, median time from initial to final propofol dose was 7 minutes. Median anesthesiologist time in the PACU was 13 minutes. In the sedated adjustment group, there were no clinically significant adverse events, and the pain score never exceeded 6 (of a possible 10). Median duration of PACU stay was shortest in the group not requiring adjustment.ConclusionsSedated suture adjustment allows for fine-tuning of postoperative binocular alignment in children and uncooperative adults. No adverse events were observed in our study group, but the procedure does increase the time patients spend in the hospital. This work will inform disclosure of risks and benefits of sedated adjustment while allowing for more accurate assessment of the cost and quality of adjustable sutures in children.Copyright © 2017 American Association for Pediatric Ophthalmology and Strabismus.
