Brief Summary

This prospective observational study aims to evaluate the relationship between preoperative ultrasonographic airway measurements and the Video-Intubation Difficulty Assessment Classification (VIDIAC) score in adult patients undergoing endotracheal intubation under general anesthesia. The study will investigate whether airway ultrasound parameters can predict difficult videolaryngoscopic intubation and assess their association with the Cormack-Lehane classification, intubation time, and other airway management outcomes.

Outcome Measures

Primary Outcomes (1)

  • To evaluate the relationship between preoperative ultrasonographic airway measurements and the VIDIAC score.

    The relationship between preoperative ultrasonographic airway measurements and the Videolaryngoscopic Intubation and Difficult Airway Classification (VIDIAC) score will be evaluated in adult patients undergoing videolaryngoscopic intubation. The simplified VIDIAC score classifies patients as easy (-1 or 0), moderate (1), hard (2), or severe (≥3), with higher scores indicating greater videolaryngoscopic intubation difficulty. Correlations between ultrasonographic airway measurements and the VIDIAC score will be analyzed.

    During videolaryngoscopic intubation

Secondary Outcomes (7)

  • Incidence of Difficult Videolaryngoscopic Intubation

    During videolaryngoscopic intubation

  • Cormack-Lehane Grade

    During videolaryngoscopic intubation

  • Intubation Time

    During videolaryngoscopic intubation

  • First-Attempt Intubation Success Rate

    During videolaryngoscopic intubation

  • Requirement for Additional Airway Maneuvers

    During videolaryngoscopic intubation

  • +2 more secondary outcomes

Study Population

The study population will consist of adult patients aged 18-80 years who are scheduled to undergo elective surgical procedures requiring endotracheal intubation under general anesthesia at Samsun City Hospital. Eligible patients with ASA physical status I-III who provide written informed consent and meet all inclusion criteria will be consecutively enrolled in the study.

You may qualify if:

  • Adults aged 18 to 80 years.
  • American Society of Anesthesiologists (ASA) physical status I-III.
  • Patients scheduled for endotracheal intubation under general anesthesia.
  • Patients who provide written informed consent.

You may not qualify if:

  • Known airway abnormalities.
  • Head and neck tumors.
  • Patients with a tracheostomy.
  • Pregnant patients.
  • Emergency surgical procedures.
  • Patients with limited cervical mobility.
  • Patients with facial trauma.
