A variable dimensional aerosol shield provides for perioperative COVID-19 patients

摘要

Coronavirus disease (COVID-19) transmissions are mainly through direct exposure to droplets from an infected patient, as a result of coughing, sneezing or other direct contact. 1 Some “devices” have been proposed to protect health care provides by limiting exposure during airway manipulation. Canelli et al. suggested a preformed “aerosol box” to protect clinicians from droplets spreading. But the major limitation of this device is the restricted hand movement during intubation. As a result, this approach has not been as effective during difficult airway management.
