Laryngeal Handshake for Identifying the Cricothyroid Membrane

South Korea123 participantsStarted 2017-04-20

Plain-language summary

The cricothyroid membrane is the most common position that the invasive airway secure is performed, but it is not easy to identify the cricothyroid membrane by tactile perception. Although it is recommended to use the laryngeal handshake method for identifying the cricothyroid membrane in difficult airway society 2015 guidelines for management of unanticipated difficult intubation in adults, there is only suggestion without clinical data about how much the laryngeal handshake method improves the accuracy of identification of the cricothyroid membrane So we made the hypothesis that the cricothyroid membrane is identified more correctly when the laryngeal handshake method is used than when that method is not used. And we try to find out whether there is actual difference about identification of the cricothyroid membrane between using the laryngeal handshake method and not using that method. By identifying the difference between them, we are going to support the recommendation of guidelines and make the evidence for educating the doctors who have any possibility to perform the criocthyroidotomy to use the laryngeal handshake method skillfully in the 'cannot intubate, cannot oxygenate' situation.

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.
