Evaluation of Clinical Airway Assessments With a Gray Zone Approach

N/ACompletedNCT01719848

Samsung Medical Center200 enrolled

Overview

Failure of advanced airway security has been reported that it could lead lethal complication such as brain hypoxic damage. There have been controversial reports for the airway assessment tests which can predict difficult laryngoscopy. Therefore, we evaluated diagnostic validity of pre-existing airway assessment tests and scoring system using a gray zone approach in patients undergoing general anesthesia required endotracheal intubation.

POGO(percentage of glottic opening)will be evaluated by an attachable fiberoptic scope (AV scope. CAREtec CO.Ltd, Kangwon-Do, South Korea)
