GLOTTIC VIEW COMPARISON BETWEEN MCGRATH MAC VIDEO AND MACINTOSH LARYNGOSCOPES

Abstract

The purpose of the study was to compare the efcacy of the McGrath MAC videolaryngoscope and the Macintosh laryngoscope in tracheal intubation procedures. The study was conducted on 70 patients who were undergoing elective surgery and classied as ASA I or II. The patients were intubated by an anaesthesia trainee under the supervision of a senior anaesthetist. The primary outcome of the study was the improvement in the glottic view, which was assessed using the Cormack-Lehane (C-L) grading system. The results of the study indicated that the McGrath MAC videolaryngoscope provided a signicantly better glottic view compared to the Macintosh laryngoscope. 67.1% of the cases were found to have a C-L grade I view when assessed with the McGrath MAC, compared to 42.9% with the Macintosh. Furthermore, 17% of the cases showed an improvement in the glottic view to C-L grade I when assessed with the McGrath MAC. In addition to the improvement in glottic view, the study found that the McGrath MAC videolaryngoscope was easier to use and improved the self-condence of the anaesthesia trainee. This is of particular signicance in difcult airway situations where a quick and accurate intubation is of utmost importance. In conclusion, the study suggests that the McGrath MAC videolaryngoscope can be used as a safe and effective alternative airway device, providing a superior glottic view and ease of intubation in normal airway patients. The use of this device can also enhance the self-condence of anaesthetists in training, making tracheal intubation more secure and effortless in challenging circumstances.
