INFECTION
This study quantified practitioner contamination after performance of BVM, LMA insertion, and ETI, finding that aerosol box use reduces surface contamination significantly on the torso and face of airway practitioners predoffing, with little difference in the contamination of upper extremities (predoffing) in the intervention group. We found minimal amounts of surface contamination postdoffing in both control and intervention groups. Existing literature has described technical challenges associated with box use resulting in prolonged intubation times,The aerosol box was designed to mitigate HCP infection by providing a physical barrier to minimize exposure to aerosols.In this study, teams of trained airway practitioners using an aerosol box showed increased time to intubation, but no difference in time to LMA insertion or first-pass success rates (for ETI and LMA insertion) compared with teams without an aerosol box. While prior manikin-based studies report slightly longer time to intubation with aerosol box use,
