Borescope assisted intubation through Fekry intubating airway; a prospective observational study

Abstract

Objectives: Airway management starts from the use of a nasal prong for oxygenation to successful endotracheal intubation for the ventilation. Intubation has been one of the most studied subject in anesthesiology. Various methods and gadgets have been advocated for its success. We aimed to evaluate the rate of successful intubations using the ordinary borescope and a stylet through Fekry Oral Intubating Airway (FOIA) in a manikin. Methodology: This manikin-based study enrolled 35 trainees, who performed endotracheal intubation guided by the borescope and used FOIA as a conduit. Every trainee was allowed two attempts. The primary outcome was to assess the success rate of intubation. Secondary outcomes included the precise time to intubate, number of attempts, and the need for external manipulations. Results: Our results revealed that 62.9% of the participants performed the intubation successfully (success rate) and 51.43% succeeded to intubate the manikin in the first attempt. External manipulation was needed by 71.4% of the participants in the form of cricoid pressure or laryngeal movement to visualize the glottic view. The time needed for a successful intubation ranged from 16 to 120 sec with a median of 50 sec and a mean of 69.37 ± 42.26 sec. Conclusion: A combination of Fekry Oral Intubating Airway, a borescope and an intubating stylet can be used for  endotracheal intubation in remote areas, where advanced airway management aids are not available.. Future studies are warranted to optimize this technique. Trial registration: The ethical approval was obtained from the Research Ethics Committee of Cairo University (Code: MD-79-2019), and registration of the trial was performed on www.clinicaltrials.gov with a registration number (NCT05094453).
