The COVID-19 pandemic has led to the production of novel devices intended to protect airway managers during the aerosol-generating procedure of tracheal intubation. Using an in-situ simulation model, we evaluated laryngoscopist exposure of airborne particles sized 0.3 - 5.0 microns using five aerosol containment devices (aerosol box; sealed box with and without suction; vertical drape; and horizontal drape) compared with no aerosol containment device. Nebulised saline was used as the aerosol-generating model for 300 s, at which point, the devices were removed to assess particle spread. ⋯ Compared with no device use, neither horizontal nor vertical drapes showed any difference in any particle size exposure at any time. Finally, when the patient coughed, use of the aerosol box resulted in a marked increase in airborne particle exposure compared with other devices or no device use. In conclusion, novel devices intended to protect the laryngoscopist require objective testing to ensure they are fit for purpose and do not result in increased airborne particle exposure.

Current guidelines for perioperative management of coronavirus disease 19 (COVID-19) are mainly based on extrapolated evidence or expert opinion. We aimed to systematically investigate how COVID-19 affects perioperative management and clinical outcomes, to develop evidence-based guidelines. ⋯ CRD42020182891 (PROSPERO).

Lesson learned from China regarding use of personal protective equipment.
In Wuhan, China, in December 2019, the novel coronavirus was detected. The virus causing COVID-19 was related to a coronavirus named severe acute respiratory syndrome coronavirus (SARS-CoV). The virus caused an epidemic in China and was quickly contained in 2003. Although coming from the same family of viruses and sharing certain transmissibility factors, the local health institutions in China had no experience with this new virus, subsequently named SARS-CoV-2. ⋯ The lessons learned by health care workers in China are shared in the hope of preventing future occupational exposure.

Doctors and healthcare workers (HCW) are at frontline in control of the pandemic caused by the novel coronavirus infection (COVID-19). The virus is transmitted by contact, droplet, and airborne transmission; hence, hand hygiene, social distancing, environmental disinfection, and use of appropriate personal protective equipment (PPE) form important components to protect HCWs from cross-infection. Appropriate use of PPE is of paramount importance not only to reduce the risk of transmission but also to maintain adequate stock for those who are dealing directly with COVID-19 patients. ⋯ Adherence to protective measures and use of PPE is of utmost importance for HCWs to prevent cross-infection in this pandemic. The use of PPE can limit transmission to a great extent, but appropriate use and avoiding misuse is equally important in the dermatology setting in order to avoid depletion of stock. It is also essential to consider various practical issues with use of PPE and device measures to avoid them so that breach in protocols can be prevented and spread of infection minimized.
