NCT07606079

Brief Summary

Although many tests exist for predicting a difficult airway, the search for a test with substantially higher specificity and sensitivity is still ongoing. The aim of this study is to evaluate the specificity and sensitivity of modified thyromental distance and modified sternomental distance measurements, scaled according to the patient's own three-finger breadth, in predicting difficult laryngoscopy and difficult tracheal intubation.

Outcome Measures

Primary Outcomes (1)

  • Sensitivity and specificity of patient-specific modified thyromental distance for predicting difficult intubation

    During the 6-month study period, for each patient, the Cormack-Lehane score will be recorded when direct laryngoscopy is performed after induction of anesthesia in the perioperative period.
