Real-World Evaluation of i-gel Introduction on Intraoperative Airway-Related Safety Events: A Retrospective Cohort Study From a New England Hospital Network.

Background: Several health care networks have fully adopted second-generation supraglottic airway (SGA) i-gel. Real-world evidence of enhanced patient safety after such practice change is lacking. We hypothesized that the implementation of i-gel compared to the previous LMA®-Unique™ would be associated with a lower risk of airway-related safety events.
