A SYSTEMATIC REVIEW OF ADJUSTABLE BOUGIE COMPARED WITH HOOKS AIRWAY CATHETER FOR INTUBATION TO CMAC VIDEO LARYNGOSCOPY

Abstract

Aim: This systematic review aims to critically evaluate and compare the efficacy, safety, and overall performance of the adjustable bougie and the hooks airway catheter as adjuncts to CMAC video laryngoscopy for endotracheal intubation.

Materials and method: A systematic review with total number of 319 articles were searched using PubMed, SCOPUS, Elsevier Science Direct, Wiley online library, Cochrane library, Prospero, Cinahl, Ovid Medline, and Grey literature was conducted following PRISMA guidelines. Randomized controlled trials comparing Airway Catheter Intubation and CMAC Video Laryngoscopy in Bougie were included. Three studies meeting inclusion criteria were included for analysis. Bias assessment was done using Cochrane-based assessment tool 2 (ROB2).

Results: Three studies met the inclusion criteria. The first study demonstrated superior success rates with CMAC videolaryngoscopy compared to direct laryngoscopy in challenging airways. The second study found that smoother and swifter intubation with a 60° angled styletted endotracheal tube compared to a bougie when combined with CMAC videolaryngoscopy. The last study observed that slightly prolonged intubation duration with the use of a Frova introducer alongside CMAC videolaryngoscopy.

Conclusion: The findings highlight the efficacy of CMAC videolaryngoscope in facilitating successful intubation, particularly in challenging airway scenarios. While adjunctive devices like the Frova introducer and bougie present additional considerations, standardized protocols and further research are needed to elucidate optimal intubation strategies. Continued investigation and refinement of techniques are essential to enhance patient safety and outcomes in anesthesia practice.
