Evaluation of Clinical Airway Assessments With a Gray Zone Approach
Completed
- Conditions
- Difficult Laryngoscopy
- Registration Number
- NCT01719848
- Lead Sponsor
- Samsung Medical Center
- Brief Summary
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.
- Detailed Description
POGO(percentage of glottic opening)will be evaluated by an attachable fiberoptic scope (AV scope. CAREtec CO.Ltd, Kangwon-Do, South Korea)
