Should the Glidescope video laryngoscope be used first line for all oral intubations or only in those with a difficult airway? A review of current literature
The purpose of this study was to review literature that looked into the efficacy of the Glidescope video laryngoscope versus the Macintosh laryngoscope in oral endotracheal intubations. We aimed to answer the question ‘Should the Glidescope video laryngoscope laryngoscopes be used as first line intubation aids or only in the difficult airway?’ A systematic search of electronic databases was made. The inclusion criteria included: Glidescope, video laryngoscope, and Macintosh laryngoscope in human studies. The study aimed to compare first attempt success rate, glottic view and intubation time in papers dating between 2009 and 2017. Eleven trials with a total of 7,919 patients with both difficult and normal airways were included. The trials showed an improvement in first attempt success rate and glottic view with the Glidescope video laryngoscope especially in those with difficult airways. Overall time to intubate showed no significant differences between the Glidescope video laryngoscope and the Macintosh laryngoscope although it was identified that with increased training and experience with the Glidescope video laryngoscope, intubation time was reduced. Glidescope video laryngoscopes show advantages over the Macintosh laryngoscopes in obtaining better glottic views in those with difficult airways. However its use is not supported in all routine intubations.
