A NOVEL ADJUSTABLE BOUGIE COMAPARED WITH COOKS AIRWAY CATHETER FOR INTUBATION TO CMAC VIDEO LARYNGOSCOPY

Abstract

Background: Endotracheal intubation is a crucial skill in managing difficult airways. While video laryngoscopes like the C-MAC improve glottic visualization, the success of intubation also depends on the adjunctive devices used. This study evaluates the efficacy of a novel adjustable bougie compared with the traditional Cook’s Airway Exchange Catheter (CAEC) during intubation using C-MAC video laryngoscopy.

Aim: To compare first-pass success rate, intubation time, ease of use, and complications between the novel adjustable bougie and Cook’s Airway Exchange Catheter in elective intubation using C-MAC video laryngoscopy.

Materials and Methods: “This prospective, randomized comparative study was conducted on 60 ASA I–III patients aged 30–60 years undergoing elective surgery under general anesthesia at Saveetha Medical College, Chennai. Patients were randomly allocated into two groups: Group A (n=30) used the adjustable bougie, and Group B (n=30) used the CAEC for intubation. Outcome measures included first-pass success rate, time to intubation, ease of intubation (Likert scale), complications, and need for additional maneuvers. Data were analyzed using SPSS v26.0 with a significance level of p<0.05”.

Results: The adjustable bougie group demonstrated a higher first-pass success rate, shorter intubation time, and improved ease of intubation compared to the CAEC group. Complication rates and need for additional maneuvers were lower in the bougie group, though not statistically significant.

Conclusion: The novel adjustable bougie proved to be more effective and user-friendly than the traditional CAEC when used with C-MAC video laryngoscopy, offering improved intubation outcomes in elective airway management.
