Abstract

Purpose: To study the efficiency and utility of laryngeal mask airway (LMA) compared to endotracheal intubation (ETI) in vitreoretinal surgery. Methods: A retrospective chart review was conducted on vitreoretinal surgery cases using LMA or ETI from 2014-2018. 278 vitreoretinal surgery patients (139 LMA patients, 139 ETI patients) were included from one health system and two surgeons. Operating room efficiency and airway complications were analyzed using Cohcran-Armitage Trend, Wilcoxon Rank Sum, Chi-Square, and Two-Sample t-Tests. Results: Compared to ETI, LMA patients had a statistically significant faster time to successful airway insertion (3 minutes faster), time to case start (8 minutes faster), and total time in operating room (25 minutes faster). These trends remained statistically significant after subanalysis by type of vitreoretinal surgery and American Society of Anesthesiologists (ASA) score. Demographics were balanced by age and gender. No complications occurred with LMA No patients were converted from LMA to ETI. Conclusions: LMA is an efficient and safe alternative to ETI for vitreoretinal surgery.
