Randomized Controlled Trial
Impact of aerosol box on intubation during COVID-19: a simulation study of normal and difficult airways.
Patients with coronavirus disease (COVID-19) are at risk of requiring mechanical ventilation, and concerns of protecting healthcare workers during aerosol-generating medical procedures has led to the design of the aerosol box. ⋯ In this mannequin-based simulation study, the use of the aerosol box increased the time to intubation in some contexts but not others. Further studies in a clinical setting should be conducted to make appropriate modifications to the aerosol box to fully elicit its efficacy and safety prior to implementation in airway guidelines for managing patients with COVID-19.

Randomized Controlled Trial
Comparison of high flow nasal oxygen and conventional nasal cannula during gastrointestinal endoscopic sedation in the prone position: a randomized trial.
Deep sedation for endoscopic retrograde cholangiopancreatography (ERCP) can be challenging in elderly patients in the prone position. This study investigated the effect of a high flow nasal oxygen (HFNO) delivery system on oxygenation in this procedure compared with that of conventional nasal cannula oxygen administration. ⋯ In contrast to conventional nasal cannula, high flow nasal oxygen provided adequate oxygenation without causing procedural interruptions during ERCP, suggesting that HFNO may be used as a standard oxygen delivery method during these procedures.
