Enhancing Difficult Laryngoscopy Prediction Through A Mixed Scoring System

Lebanon1,100 participantsStarted 2025-02-20

Plain-language summary

This study aims to develop a comprehensive airway assessment score including traditional bedside clinical tests and ultrasound measurements with high accuracy in predicting difficult airway, and to validate it through testing it on a large population sample. The main question it aims to answer is: Is the comprehensive scoring system that includes clinical bedside and ultrasound measurements developed to predict difficult airways valid in a large population sample? Adult patients undergoing general anesthesia with American Society of Anesthesiologists (ASA) classification 1-4 will be recruited. Traditional and ultrasound measurements will be collected.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
