A Randomised Control Study to compare the hemodynamic stress responses during laryngoscopy and tracheal intubation using Coopdech® VLP-100 Videolaryngoscope as compared to Macintosh laryngoscope

The Coopdech® Video Laryngoscope VLP-100™ (CVL) is a digital intubation tool that allows direct visualization of the vocal cords during intubation. Laryngoscopy and intubation results in increased hemodynamic responses in patients. This prospective, randomized control study was conducted to evaluate and compare the hemodynamic responses during laryngoscopy and intubation with the CVL and Macintosh laryngoscopes in patients without comorbidities. A total of 140 patients were equally and randomly divided into two groups and the mean heart rate, systolic blood pressure, diastolic blood pressure, and mean arterial pressure were compared at baseline, after induction, before laryngoscopy, and at different points of time after intubation. The results showed a significant rise in all parameters at 1 minute and 3 minutes after intubation in both groups (p<.05), but no significant difference in parameters between the two groups (p>.05). The time taken to intubate was significantly more with the Coopdech Videolaryngoscope than with the Macintosh laryngoscope. The study concluded that the Coopdech videolaryngoscope did not show any advantage over the Macintosh laryngoscope in terms of attenuating hemodynamic responses following laryngoscopy and orotracheal intubation.
