A Predictive Model for Difficult Intubation
February 28, 2017 updated by: Thepakorn Sathitkarnmanee, Khon Kaen University
A New Prognostic Model Developed by Using Multi-predictive Tests for Prediction of Difficult Intubation in Adult Anesthetic Patients
Failure in airway management is one of the most common anesthesia-related morbidity and mortality.
Each individual airway assessment has limitation to predict difficult intubation.

Detailed Description
Objective: To develop a scoring model from multiple airway assessment to predict difficult intubation.
Methods: This will be a retrospective analytic study. All airway assessment data from medical records of patients aged more than 18 years old underwent general anesthesia in Srinagarind hospital from January 2012 to December 2014 will be used to develop a new scoring prediction model.
