Non-inferiority Trial Comparing visionPRO to Glidescope Video Laryngoscopes

100 participantsStarted 2025-01-01

Plain-language summary

Indirect video laryngoscope tracheal intubation with the GlideScope (Verathon Inc., Bothell, USA) has become a well-established technique in emergency and clinical anaesthesia, offering first-pass intubation success rates comparable to those achieved with direct laryngoscopy. Different video laryngoscopes vary significantly in design, including blade shape, mobility, and camera operation, which can affect patient outcomes. Two video laryngoscopes with hyperangulated blades include the GlideScope (Verathon Inc., Bothell, USA) and the visionPRO (HEINE® Optotechnick, Gilching, Germany). The Glidescope comprises an external monitor connected to a medical-grade plastic handle which is compatible with reusable and disposable blades. The newer visionPro comprises a reusable anodized aluminum integrated monitor that is attached to the camera/handle which is compatible with disposable blades. The hyperangulated blade of the VisionPro is a unique combination of previously designed laryngoscope blades meant to increase performance. The introduction of this new hyperangulated blade design in the VisionPro raises the need to compare its performance against the established GlideScope. The aim of this pilot study is to generate initial data to evaluate whether the use of the visionPRO (HEINE® Optotechnick, Gilching, Germany) provides a non-inferior first-pass success rate compared with the GlideScope (Verathon Inc., Bothell, USA) in surgical patients with an expected normal airway undergoing general anaesthesia The investigators hypothesize that tracheal intubation using the HEINE visionPRO will achieve a similar frequency of failed intubation and airway complications. This study plans to recruit 100 patients.

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.
