Improving predictions for difficult airway management
Official title: Enhancing Difficult Laryngoscopy Prediction: A Prospective Study on A Mixed Scoring System With Ultrasound and Traditional Metrics
Run by American University of Beirut Medical Center · NCT06815952 · Data updated 2026-11-12
This study is testing a new scoring system that uses both traditional checks and ultrasound images to better predict if adults will have a hard time with their airway during anesthesia.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adult patients classified as ASA 1-4 who are scheduled for general anesthesia, whether for emergency or elective procedures.
✕Probably not a fit
Patients with a confirmed history of difficult airway or specific conditions such as maxillofacial trauma or cervical spine instability may not benefit from this study.

What this trial studies
This study aims to create a comprehensive scoring system that combines traditional clinical assessments and ultrasound measurements to accurately predict difficult airway scenarios in adult patients undergoing general anesthesia. By validating this scoring system on a large population sample, the research seeks to enhance the reliability of airway assessments, which are crucial for avoiding complications during intubation. Data will be collected preoperatively, including various traditional metrics and ultrasound measurements, to develop a more effective predictive tool.
Why it matters
Potential benefit: If successful, this study could significantly reduce complications related to difficult intubation by providing a more accurate prediction method.
How similar studies have gone: While various scoring systems have been developed for airway assessment, this approach combining ultrasound measurements is relatively novel and has not been extensively tested in prior studies.

Timing of a single dexmedetomidine dose before laryngoscopy and intubation and its effect on stress response.
This trial will test whether giving one dose of dexmedetomidine earlier or closer to surgery can reduce the blood pressure and heart rate changes caused by laryngoscopy and intubation in adults aged 18–65 with ASA I–II.
