The coronavirus disease 2019 pandemic has necessitated rapid adaptations to all levels of clinical practice. Recently produced guidelines have suggested additional considerations for tracheostomy and advocated full personal protective equipment, including filtering facepiece code 3 masks. Air seal with filtering facepiece code 3 masks is often challenging, and full-face respirators and powered air-purifying respirators with hoods need to be employed. The infection prevention benefits of this equipment are accompanied by potential issues in communication.

In an attempt to minimise surgical error through miscommunication, the authors sought to introduce a simple sign language system that could be used as an adjunct during surgery.

Following evaluation of pre-existing sign language platforms and consideration of multiple surgical factors, 14 bespoke hand signals were ultimately proposed.

Whilst this novel sign language system aims to bridge the communicative gap created by additional personal protective equipment, further development and validation of the proposed tool might be beneficial.

This study examined homemade masks as an alternative to commercial face masks.

Several household materials were evaluated for the capacity to block bacterial and viral aerosols. Twenty-one healthy volunteers made their own face masks from cotton t-shirts; the masks were then tested for fit. The number of microorganisms isolated from coughs of healthy volunteers wearing their homemade mask, a surgical mask, or no mask was compared using several air-sampling techniques.

The median-fit factor of the homemade masks was one-half that of the surgical masks. Both masks significantly reduced the number of microorganisms expelled by volunteers, although the surgical mask was 3 times more effective in blocking transmission than the homemade mask.

Our findings suggest that a homemade mask should only be considered as a last resort to prevent droplet transmission from infected individuals, but it would be better than no protection. (Disaster Med Public Health Preparedness. 2013;0:1–6)
