Study summary

In this study, the investigators will evaluate the advanced airway methods applied in the anesthesiology and reanimation clinic of the hospital to patients who met the criteria for awake intubation specified in the ASA 2022 difficult airway management guideline or who could not be intubated after induction of anesthesia in another center. The advanced airway method applied to the difficult airway patient expected in the operating room, the duration, success and complications of the method will be observed and recorded.

Read the detailed description

Patients who meet the inclusion criteria will be informed about the difficult airway and their verbal and written consent will be obtained.

When participants are taken to the room, an observer will be in the operation room. There was no emergency to the patient's primary anesthesiologist, will not be involved. Record patients' demographic data, Mallampati scores, thyromental distance, and neck circumference.

The airway method preferred by the physician, procedure duration, number of attempts, success, and complications will be recorded.

What researchers measure

Primary outcomes

  1. Comparison of advanced airway methods in the awake patient with difficult airway.

    Comparison of the superiority of advanced airway methods applied to the expected difficult airway patient in the operating room. The number of attempts and duration for successful intubation between groups will be examined.
