Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
