Abstract

Introduction: As is well described laryngoscopy and intubation produce significant hemodynamic response. It is shown in previous studies that type of laryngoscope blade used affects the degree of hemodynamic response to endotracheal intubation. In our study we have attempted to compare hemodynamic response to laryngoscopy and intubation using Macintosh and McCoy blade.
Aim: Our aim was to perform comparative study of hemodynamic response to laryngoscopy and intubation using Macintosh versus McCoy blade.
Materials and Methods: A prospective randomized controlled study comparing hemodynamic response to laryngoscopy and intubation using Macintosh and McCoy blade was conducted. A total no. of Sixty patients, either male or female, between age group of 20 -50yrs, belonging to American Society of Anaesthesiology physical status I and II requiring General anaesthesia were randomly allocated to either group A (Macintosh group) or group B (McCoy group) In both the groups, standard methods were used. Comparison of hemodynamic parameters i.e. Heart rate (HR), systolic (SBP) diastolic (DBP) and mean blood pressure (MAP) was done at induction, during laryngoscopy and intubation, till 5 mins after intubation.
Statistical Analysis: Hemodynamic changes in between the two groups were compared statistically using Unpaired “t” tests.
Results: Significant rise in all HR, SBP, DBP, MAP was seen in both the groups after laryngoscopy and intubation. In group A the rise was found to be statistically significant as compared to group B.
Conclusion: This study helped us to conclude that McCoy blade produces reduced hemodynamic response to laryngoscopy and intubation as compared to Macintosh blade.
