A Prospective Observational Study Comparing Three Different Techniques of Intubation Using C-Mac Video Laryngoscope

Aim: To compare three different techniques of endotracheal intubation using C-MAC video laryngoscope. Methodology: A prospective, randomized clinical study. A total 60 patients of ASA physical status I and II, aged 18 – 60 years were randomly divided into three groups of 20 each. In Group NS patients were intubated using ETT alone, Group S – stylet was used and Group B – bougie was used. Comparison was done in terms of time for intubation, procedure time and success rate. Results: All the patients in B group were intubated in first attempt whereas maximum number of attempts was required in NS group followed by S group. Mean intubation time was least for S group followed by B group and maximum for NS group with significant p value between NS vs S and S vs B. Mean procedure time taken was least for S group followed by NS group and maximum for B with significant p-value between NS vs S group and S vs B. Conclusion: Use of bougie as an aid to endotracheal intubation performed best as compared to stylet or no stylet when used with conventional C–MAC blade.
