Abstract
Endotracheal intubation and laryngoscopy are critical procedures in anesthesia and emergency medicine, where securing a patent airway is essential. The McCoy laryngoscope, with its hinged tip, is widely used to improve visualization of the glottis, especially in difficult airways. The Flexi Doshi laryngoscope, a newer design, features an enhanced blade with a similar hinged tip and additional modifications aimed at improving intubation efficiency. This study compares the Flexi Doshi and McCoy laryngoscope blades in terms of laryngoscopic view, ease of intubation, time to intubation, and hemodynamic responses. This prospective, randomized study was conducted at ESIC Medical College, Kalaburagi, Karnataka, over one year. Seventy‐four patients scheduled for elective surgery under general anesthesia were randomly assigned to two groups: Group F (Flexi Doshi) and Group M (McCoy), with 37 patients in each group. Laryngoscopic view was assessed using the Cormack and Lehane grading system and ease of intubation was evaluated using Arino’s grading. Time to glottic visualization (Tv) and time to intubation (Ti) were recorded. Hemodynamic parameters were monitored at pre‐induction, and 1, 3, and 5 minutes post‐intubation. Statistical analysis was performed using SPSS version 25. The Flexi Doshi blade provided a significantly better laryngoscopic view, with a higher proportion of patients achieving a Grade 1 view (p =0.04). The time to glottic visualization (Tv) and time to intubation (Ti) were shorter in the Flexi Doshi group (p=0.01 and p= 0.02, respectively). Ease of intubation was marginally better in the Flexi Doshi group, with more patients graded as having easy intubation (Grade 1) compared to the McCoy group (p = 0.05). Hemodynamic responses were similar between the groups, with no significant differences in heart rate, blood pressure, or oxygen saturation at any time point. The Flexi Doshi laryngoscope blade demonstrated advantages over the McCoy blade in providing a better laryngoscopic view and facilitating quicker and easier intubation, while maintaining comparable hemodynamic stability. These findings suggest that the Flexi Doshi blade may be a preferable option in situations requiring efficient and reliable intubation.
