| Popis: | Frontline health care workers who perform potentially aerosol-generating procedures, such as endotracheal intubations, in patients with coronavirus disease 2019 may be at an increased risk of exposure to severe acute respiratory syndrome coronavirus 2. To continue to care for patients with coronavirus disease 2019, minimizing exposure is paramount. Using simulation, we devised a testing method to evaluate devices that may mitigate the spread of aerosol and droplet-sized particles.In this prospective single-center study, participants intubated a manikin 3 times using standard personal protective equipment, once with no barrier device, once with an acrylic box, and once with a modified horizontal drape. The micrometer-sized particle count, generated by a nebulization model, was recorded before and after each intubation. The first-pass intubation rate and time to intubation were recorded. Each operator completed a postsimulation survey about their experience using the barrier devices.Thirty airway proceduralists completed the simulation and survey. There was no significant difference in particle counts (aerosols or droplets) or first-pass intubation, but the horizontal drape was found to significantly increase intubation time (P = 0.01). Most participants preferred the drape over the acrylic box or no barrier device.The acrylic box and plastic drape did not mitigate particle spread. However, our testing method can be used to test barrier designs using negative pressure or other mitigation strategies for particle spread. |
