First-Attempt Endotracheal Intubation Success Rate Using A Telescoping Steel Bougie

Abstract

Background There has been a renewed interest in using the plastic intubation bougie to facilitate first-attempt endotracheal intubation success. The sterile single-use telescopic steel bougie (AIROD) was invented to overcome the limitations of the plastic bougie which is easily deformed during storage. Methods This is a retrospective study involving critically ill patients who were intubated with the AIROD in the intensive care unit at a single institution. The purpose of this case series is to compare the success rate of the AIROD to the generally accepted success rate for the traditional plastic bougie of 96%. Results A total of 54 patients were enrolled at a single ICU over a 10 months period. All patients were critically ill with 76% having a difficult airway, Cormack-Lehane grade view 2 or greater in 60%, and ARDS secondary to COVID-19 in 54%. The primary outcome of first-attempt intubation success in critically ill patients intubated in the ICU with the AIROD was 97% with a 95% confidence interval of 0.89 to 0.99. The average time for intubation of all airway classifications was 15 seconds. Conclusion The AIROD first-attempt intubation success rate was found to be similar to the rate for the traditional plastic bougie.
