Background: Obtunding, the hemodynamic responses during laryngoscopy and intubation, remains a major concern for anesthesiologists. The present study compared the haemodynamic changes and glottic visualization during intubation between C-MAC, Mc Coy and Macintosh Laryngoscopes.
Methods: We conducted the study on 150 patients under ASA I or ASA II scheduled for elective surgery. The patients were randomly assigned to one of the three groups containing 50 patients using a computer-generated random allocation chart. The intubation was performed with Group-A (Macintosh), Group-B (McCoy) and Group-C (C-MAC). Hemodynamic variables such as Heart rate, Systolic blood pressure, diastolic blood pressure, and mean arterial pressure were recorded before, during and till 5 minutes post-intubation, and glottis opening was assessed with Cormack Lehane grading.
Observations and Conclusion: There was a statistically significant increase in hemodynamic parameters during laryngoscopy and intubation of patients of all three study groups. Still, less increase in hemodynamic responses was observed in patients intubated with McCoy laryngoscope compared to those intubated with Macintosh and C Mac laryngoscope. The C Mac laryngoscope shows better visualization of the glottis when compared to that of Macintosh and McCoy.

Key words: Airway, laryngoscopes, hemodynamics
