Non-inferiority Trial Comparing visionPRO to Glidescope Video Laryngoscopes

Sponsor: London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's

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.
