Abstract
Objectives: Worldwide efforts to protect front line providers performing endotracheal intubation during the COVID-19 pandemic have led to innovative devices. Authors evaluated the aerosol containment effectiveness of a novel intubation aerosol containment system (IACS) compared with a recently promoted intubation box and no protective barrier. Methods: In a simulation center at the authors’ university, the IACS was compared to no protective barrier and an intubation box. Aerosolization was simulated using a commercial fog machine and leakage of aerosolize mist was visually assessed. Results: The IACS appeared to contain the aerosolized mist, while the intubation box allowed for mist to contact the laryngoscopist and contaminate the clinical space through arm port holes and the open caudal end. Both devices protected the laryngoscopist better than no protective barrier. Discussion: The IACS with integrated sleeves and plastic drape appears to offer superior protection for the laryngoscopist and assistant providers from aerosolized particles.

AND CLINICAL NEED COVID-19 is primarily spread via small droplets generated during a cough or sneeze
Worldwide efforts to develop personal protective equipment (PPE) for front line providers performing endotracheal intubation during the COVID-19 pandemic have led to innovative devices such as the intubation box [1], [2]
In 4 trials, the proposed intubation aerosol containment system (IACS) introduced in this article exhibited improved containment of the aerosolized mist
Summary
AND CLINICAL NEED COVID-19 is primarily spread via small droplets generated during a cough or sneeze Certain procedures, such as intubation, increase the risk of aerosolizing large quantities of small and micro particles that are highly infectious and increase the risk to nearby providers. Worldwide efforts to develop personal protective equipment (PPE) for front line providers performing endotracheal intubation during the COVID-19 pandemic have led to innovative devices such as the intubation box [1], [2]. While this barrier has been shown to limit macroscopic contamination on the laryngoscopist, there is still concern for viral exposure through aerosolization of microscopic particles in several clinical settings. This article introduces a novel protective barrier and assesses its ability to contain aerosolized mist compared with the intubation box and no protective barrier [1]
