Blind Tracheal Intubation Through Supraglottic Airway Devices
Egypt70 participantsStarted 2022-12-17
Plain-language summary
Tracheal intubation is considered the gold standard for protecting the airway. As the supraglottic airway devices (SADs) could be inserted without laryngoscopy, so that SADs with different designs and safety issues could be used to manage difficult airways in anesthesia and emergency medicine with continuous patient oxygenation \&ventilation, less hemodynamic stress response and less postoperative complications. These advantages encourage the use of a proper SAD as a conduit for endotracheal intubation in stressful conditions. This study will be carried out to compare the Air-QTM Blocker and LarysealTM Pro for blind tracheal intubation during elective ophthalmic surgeries under general anesthesia. Intubation through SAD can be performed using a fiber-optic bronchoscope or blindly. Blind intubation is meaning that the tube is inserted through SAD without direct visualization of the airway. Success rate of blind intubation ranges between 15% and 97%, mostly depending on the type of used SAD, patient characteristics and operator skills. The availability of blind intubation through SAD is important in cases of difficult intubation (either anticipated or unanticipated) especially if fiber-optic is not available, so that SAD will be convenient for untrained personnel.

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?

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?
