Aerosol Box Use in Reducing Health Care Worker Contamination During Airway Procedures (AIRWAY Study)): A Simulation-Based Randomized Clinical Trial
Authors' conclusion
In this randomized clinical trial of aerosol box use in AGMPs, use of an aerosol box reduced contamination deposition on HCPs' torso and face predoffing; the use of an aerosol box delayed time to successful intubation.
Study context
- Population
- Teams of 2 health care practitioner (HCPs) at tertiary care pediatric hospitals performing simulated bag-valve-mask ventilation, endotracheal intubation (ETI) and laryngeal mask airway (LMA) insertion122 analysed (61 teams)
- Participants
- 128 participants
- Comparison
- Aerosol box vs no aerosol box during simulated aerosol-generating medical procedures (AGMPs)
- Primary endpoint
- Surface area of contamination (AOC) on participants
