Evaluation of McGrath® MAC Video Laryngoscope

2014-02-27 17:00:00 | BioPortfolio

Summary

The purpose of this study is to evaluate whether the McGrath® MAC video laryngoscope is equal or superior when compared to the Glidescope® Ranger and the Macintosh laryngoscope for novice users in a simulated airway manikin.

Description

Investigators compared two portable video laryngoscopes (the GlidesScope® Ranger (Verathon Inc, Bothell, WA, USA) and the McGrath® MAC (Aircraft Medical Ltd, Edinburgh, UK)) and a German type Macintosh metal blade with a fiberoptic light. A blade size of 4 was used on all devices. All intubations using video laryngoscopes were performed according to the manufacturers' instructions. A specialised rigid stylet (the GlideRite®) was used with the Glidescope® and a flexible plastic stylet bent with a hockey stick curvature, was used with the McGrath® MAC and the Macintosh laryngoscope. A size 7.5 endotracheal tube (Mallinckrodt™ Hi-Lo Oral/Nasal Tracheal Tube Cuffed Murphy Eye, Covidien, Ireland) was used with all the laryngoscopes.

All participants were randomly divided into 3 device groups. Each group was allowed to attempt to perform endotracheal intubation five more times using the Laerdal® Airway Management Trainer (Laerdal Medical Korea Ltd., Seoul, Korea) with the normal airway setting. After completing the normal airway session, the participants performed another five attempts with the neck immobilisation setting using a neck collar.

The sequence in which the three devices were used was randomly assigned, and all participants performed the same sequence at intervals of five weeks during the study.

Medical and Biotech [MESH] Definitions

Used with articles which include video files or clips, or for articles which are entirely video.

Endoscopic surgical procedures performed with visualization via video transmission. When real-time video is combined interactively with prior CT scans or MRI images, this is called image-guided surgery (see SURGERY, COMPUTER-ASSISTED).

A form of interactive entertainment in which the player controls electronically generated images that appear on a video display screen. This includes video games played in the home on special machines or home computers, and those played in arcades. (McGraw Hill Encyclopedia of Science & Technology, 7th ed, v19, p223)

Endoscopic surgery of the pleural cavity performed with visualization via video transmission.

The storing or preserving of video signals for television to be played back later via a transmitter or receiver. Recordings may be made on magnetic tape or discs (VIDEODISC RECORDING).
