To assess the ease of intubation with and without bougie.
To assess Time taken for successful intubation.

Material and Methods: A randomised, prospective, comparative, interventional study, on 60 patients posted for Urological procedures under general anaesthesia with endotracheal intubation and controlled ventilation was conducted in a single centre. The patients included in the study were intubated with or without bougie using a channelled video laryngoscope after induction of anaesthesia.
Results: The demographic data such as age, sex and BMI, ASA physical status, airway assessment were matched in both the groups. The heart rates, systolic and diastolic blood pressure, SP02, ETCO2 variations post-procedure and complications were statistically comparable in both the groups. Ease of insertion was better when intubation was done with channelled video laryngoscope alone than with bougie aided channelled video laryngoscopy intubation, but was not statistically significant. Time taken for intubation was significantly higher in the bougie aided group than unaided channelled video laryngoscopic intubation. Various manoeuvres to negotiate ETT across the glottis were more frequently used in bougie aided group, but were not statistically significant.
Conclusion: Intubation with unaided channelled video laryngoscope, offered less intubation time compared to bougie assisted channelled video laryngoscopic intubation. With channelled video laryngoscope ease of intubation was better and fewer manoeuvres were required, though statistically not significant
