Background: The Macintosh (MAC) laryngoscope has been the gold standard for teaching intubation till date. This manikin-based study was conducted to determine whether McGrath™ videolaryngoscope (VL) (McG) is comparable to MAC laryngoscope as an educational tool for novice airway managers. Material and Methods: A randomised cross-over manikin-based trial was conducted in a group of 44 final-year medical students. After training for intubation with both laryngoscopes, the students were randomised to Group MAC or Group McG to decide which laryngoscope would be used first. The total time for intubation, number of attempts for successful intubation, ease of visualisation and ease of intubation were assessed. Results: The median time for intubation was 40 s (interquartile range [IQR] 16.5–93.5) for the MAC group and 35 s (IQR 17.5–54.5 s) for McG group (P = 0.22). First attempt success was significantly more in the McG group. Ease of visualisation and ease of intubation were significantly better in the McG group (P ≤ 0.05). Conclusion: The McGrath™ VL appears to be superior to MAC laryngoscope as an educational tool for training novice airway managers in endotracheal intubation. |
