ABSTRACT

 

Introduction: In recent years, video laryngoscopes, like GlideScope® and C-MAC®, have emerged as essential tools in the management of unanticipated difficult or failed laryngoscopic intubation. The ease

of directing and inserting the endotracheal tube through the vocal cord has improved significantly when intubating with such devices. This prospective, randomised, single blinded clinical trial compared the ease of intubation between GlideScope® and C-MAC® videolaryngoscopes for novices. Materials and Methods: A total of 56 American Society of Anaesthesiologists (ASA) physical status I or II patients scheduled for elective surgery requiring endotracheal intubation under general anaesthesia, without any features suggestive of difficult intubation, were randomly allocated to either the GlideScope® Group (n=28) or C-MAC® Group (n=28). Following induction of anaesthesia with intravenous fentanyl, propofol and either rocuronium or atracurium, endotracheal intubation was carried out by junior anaesthesiology trainees using either one of the two videolaryngoscopes. The following parameters were recorded: the success of intubation at first attempt, the intubation time for successful first attempt and the number of optimisation manoeuvres required. Results: More novices in the GlideScope® Group (14.3%) required more than one intubation attempts and optimisation manoeuvres compared to those in the C-MAC® Group. The intubation time for successful first attempt was significantly longer in the GlideScope® Group compared to the C-MAC® Group (median 51.0 vs 37.0 seconds). Conclusion: CMAC® videolaryngoscope significantly provided ease of intubation for novices compared to GlideScope® videolaryngoscope in patients without any features suggestive of difficult intubation.
