Introduction: Intubation in COVID patients is challenging. Various guidelines suggest the use of video-laryngoscope (VL) as the first device to aid intubation in a COVID patient. The best VL to facilitate intubation in such a setting especially by novices is not ascertained. We compared intubation characteristics by two VL's (McGrath-MAC and C-MAC) for intubation in a COVID simulated mannequin by novices. Methodology: This prospective randomized manikin-based crossover study was done in thirty medical professionals with no previous experience of intubation with VL. All participants were trained on Laerdel airway management trainer and were allowed 5 practice sessions with each scope with an intubation box while wearing face protective personal protective equipment (PPE). Participants were randomized into two groups of 15 each, one group performed the intubation first with McGrath and the other with C-MAC before crossing over. Results: The mean (S. D.) time to intubation was similar with both McGrath-VL and CMAC VL [31.33 (14.72) s vs 26.47 (8.5) s, P = (p-0.063)]. POGO score [mean (S. D.)] was better with CMAC [81.33 (16.24) vs 60.33 (14.73), p-0.00. The majority of the users preferred C-MAC VL for intubation (93.33%). The incidence of failed intubation and multiple attempts at intubating were similar with the two scopes. Conclusion: The time to intubation was similar with both VL's but the majority of novices preferred CMAC probably due to a bigger screen that helped them to have a better view of glottis in the COVID simulated mannequin.
