Brief Summary:
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.

Condition or disease Intervention/treatment
Difficult Intubation Procedure: Endotracheal 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.

Study Type : Observational
Actual Enrollment : 7500 participants
Observational Model: Cohort
Time Perspective: Retrospective
Official Title: A New Prognostic Model Developed by Using Multi-predictive Tests for Prediction of Difficult Intubation in Adult Anesthetic Patients
Study Start Date : September 2016
Actual Primary Completion Date : February 2017
Actual Study Completion Date : February 2017

Group/Cohort Intervention/treatment
Patient with difficult intubation
Group 1: Patient undergoing endotracheal intubation with difficult intubation Group 2: Patient undergoing endotracheal intubation without difficult intubation
Procedure: Endotracheal intubation
Endotracheal intubation under direct laryngoscopy using McIntosh blade

Primary Outcome Measures :
  1. Difficult intubation [ Time Frame: 5 minutes ]
    Laryngoscopic view: grade 1-2 = no difficult intubation; grade 3-4 = difficult intubation
