The Superiority Of Mcgrath Videolaryngoscope After Failed Conventional Laryngoscopy. The Internet Journal of Anesthesiology. 2014 Volume 33 Number 1. Abstract Background Failure in tracheal intubation is still remaining the leading cause of anesthesia-related morbidity and mortality, which has not been concluded as a solved problem for anesthesiologists in securing airway. The present study is aimed to assessed the effectiveness of McGarth Series 5 videolaryngoscope after failed Macintosh laryngoscope. Materials and Methods A total of 50 patients those intubated using McGrath videolaryngoscope after two unsuccessful attempts of Macintosh laryngoscope were included in the study. The demographic data, percentage of glottic opening and Cormack-Lehane grade of the patients were recorded. Results Fifty-five patients, in which were intubated with McGrath videolaryngoscope after a maximum number of two unsuccessfull attempts with Macintosh laryngoscope. The percentage of glottic opening is improved by 80% with McGrath videolaryngoscope compared to Macintosh laryngoscope (p < 0.01). The success rate by using McGrath videolaryngoscope for tracheal intubation was 98%. Conclusion The McGrath Series 5 videolaryngoscope improves the glottic view, and proves its effectiveness after failed direct laryngoscopy. INTRODUCTION Difficult intubation has been the challenging part of the airway management for anesthesiologists and associated with substantial morbidity and mortality (1, 2). Currently, it is well practiced and documented that direct laryngoscopy has several limitations to cope with securing difficult airway during orotracheal intubation (3). Videolaryngoscopy, which may provide a better view of the tracheal aperture with failed direct laryngoscopy, creates a potential cure to this problem (4). Videolaryngoscopes are now commonly acknowledged and accepted airway management technique that may be easy to use for inexperienced anesthesiologists (5). The McGrath Series 5 videolaryngoscope is one of these devices, consisting of a small colour digital camera and a light source at the cone end of the blade (4, 5). A display screen is mounted on the top of the laryngoscope handle, with a sterile, transparent, acrylic single use 60° angled blade (4). In contrast to a Macintosh laryngoscope, the McGrath Series 5 videolaryngoscope provides a view of the glottis without requirement of lifting the tongue (6). There has been limited systematic comparisons between the McGrath Series 5 videolaryngoscope and the Macintosh laryngoscope in difficult orotracheal intubation conditions (4, 7). According to the technical properties of the McGrath Series 5 videolaryngoscope, we hypothesised that the glottic view with McGrath videolaryngoscope is better compared to Macintosh blade.
