Background: Video-laryngoscopy gives an opportunity to objectively document the peri-operative incidence of laryngopharyngeal reflux. Materials and Methods: To quantify the local real-world incidence of laryngopharyngeal reflux, a single observer observed 100 adult patients undergoing elective video-laryngoscopy for their elective surgical procedures in the operating rooms at a single institution. Results: Laryngopharynx in 4% of patients demonstrated visible active refluxing of gastroesophageal contents cranially into laryngopharynx during video-laryngoscopy but none of those underwent suctioning to remove the actively refluxing contents before successfully attempting tracheal intubation. Conclusion: Observed laryngopharyngeal reflux during elective video-laryngoscopy was common among adult patients presenting for elective surgical procedures. The lack of suctioning prior to tracheal intubation warrants consensus discussion and statement regarding whether or not to perform suctioning of visible laryngopharyngeal reflux contents prior to intubation.
