Abstract

Background. Video laryngoscopes provide better view and can improve ease of intubation compared with standard laryngoscopes. Methods. A prospective randomized study was done on 60 patients, 18 to 65 years old, comparing McGrath video laryngoscope and Macintosh laryngoscope. The aim was to compare the ease, efficacy, and usability of them during routine airway management. The primary endpoint was duration of intubation and the secondary endpoints were Cormack and Lehane grade of laryngoscopic view, number of intubation attempts, and incidence of complications. Results. There was an increase in total duration of intubation with McGrath video laryngoscope with 42.9 ± 19.5 seconds compared to Macintosh laryngoscope with 17.9 ± 4.6 seconds. In Macintosh group, 73.3% had grade I, 20% had grade II, and 6.7% had grade III Cormack Lehane view, while in McGrath group, 83.3% had grade I, 13.3% had grade II, and 3.3% had grade III. In McGrath group, 6 patients (20%) required more than 120 seconds to get intubated and only 73.3% were intubated in 1 attempt, while patients in Macintosh group had 100% successful intubation in 1 attempt. Pharyngeal trauma was seen with McGrath videolaryngoscopy. Conclusion. Duration of laryngoscopy, intubation, and total duration of intubation were significantly higher in McGrath group than in Macintosh group. McGrath group required a higher number of intubation attempts.
