Negative-Pressure Aerosol Cover for COVID-19 Tracheostomy

Educational Objective
To understand how negative-pressure aerosol cover can decrease risk of spreading COVID-19 during tracheostomy
1 Credit CME

Because of the high virulence of the novel coronavirus responsible for causing COVID-19, many patients infected with the virus become critically ill, requiring prolonged intubation, and may ultimately require tracheostomy. Mucosal surfaces have been shown to be reservoirs for high concentrations of the virus, which can become aerosolized for up to 3 hours following manipulation.1,2 Surgeons performing tracheostomies are at high risk for exposure, and recently published guidelines recommend against elective, non–time-sensitive procedures.3 In the event that a tracheostomy is indicated in a patient with confirmed or suspected COVID-19, interventions that limit the spread of aerosols are critical to reducing exposure.4,5 Here we present the creation of a novel negative-pressure aerosol cover made out of readily available operating room materials as an additional barrier to limit the spread of aerosols during tracheostomy.
