Tiltaksbeskrivelse |
Tidsramme |
|---|---|---|
|
Incidence of difficult laryngoscopy (Cormack-Lehane grade ≥ 3)
Tidsramme: During intubation procedure (intraoperative period)
|
The proportion of patients with difficult laryngoscopy defined as Cormack-Lehane grade 3 or 4 during direct laryngoscopy.
|
During intubation procedure (intraoperative period)
|
|
Intubation Difficulty Score (IDS)
Tidsramme: During intubation procedure
|
Assessment of intubation difficulty using the Intubation Difficulty Score based on number of attempts, operators, alternative techniques, glottic exposure, lifting force, external laryngeal pressure, and vocal cord position.
|
During intubation procedure

|
Correlation between ultrasound measurements and Mallampati score
Tidsramme: Preoperative assessment
|
Correlation between tracheal diameter and skin to epiglottis distance measured by ultrasound and preoperative Mallampati classification.

Preoperative assessment

Skin-to-Epiglottis Distance Measured by Ultrasound
Tidsramme: Immediately before induction of anesthesia
|
Skin-to-epiglottis distance will be measured using ultrasound immediately before anesthesia induction.
The distance is recorded in millimeters (mm) as a continuous variable.
Larger values indicate a greater skin-to-epiglottis distance and may be associated with an increased likelihood of difficult laryngoscopy.
This is not a scored scale; therefore, no predefined minimum or maximum score exists.Cormack-Lehane Grading System.
Scores range from Grade I to Grade IV.
Grade I indicates full visualization of the glottis (easier laryngoscopy), whereas Grade IV indicates that neither the glottis nor the epiglottis is visible (most difficult laryngoscopy).
Higher grades indicate a worse airway view.
