Plain-language summary
When patients have a general anaesthetic (go to sleep for surgery), the anaesthetist often places a small tube into their windpipe (intubation) to help them breathe. To see exactly where to put the tube, the anaesthetist uses a device called a laryngoscope.
A commonly used laryngoscope is the McGrath videolaryngoscope. It has a small camera and screen to help guide safe placement of the tube. It comes in two different shapes - one shaped in the same way laryngoscopes have been shaped for the last 80 years, and another newer design (McGrath X-blade) that matches the curve of patients' tongues better.
All different classes of videolaryngoscope have been shown to have benefits to patients; however, the best videolaryngoscope shape has yet to be determined.
The McGrath X-blade is currently recommended in patients in whom the anaesthetist thinks it might be slightly more difficult to place the tube, but some anaesthetists already prefer to use it in all their patients. This is not a new device or a new technique.
In this study, the investigators wish to explore if there is any special benefit of using it in all patients, by collecting some information when the device is used.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Adult patients undergoing surgical procedures requiring tracheal intubation as part of their routine anaesthetic care
* Patients undergoing either naso- or oro-tracheal intubation
* Patients undergoing tracheal intubation with or without administration of neuromuscular blocking agents (e.g. those undergoing surgery where facial nerve or recurrent laryngeal nerve monitoring will be utilised)
Exclusion Criteria:
* Patients \<18 years of age
* Patients in whom tracheal intubation is not required as part of their routine anaesthetic care
* Patients in whom tracheal intubation was not planned as part of their routine anaesthetic care, but was required as a rescue technique (e.g. for failed insertion of a supraglottic airway) since appropriate patient consent will not have been obtained · Patients that are physiologically unstable (where clinical care must take priority and/or patient is unable to consent for inclusion in the study)
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.
