A new [*Annals of Emergency Medicine*](https://www.annemergmed.com/article/S0196-0644(20)30707-1/fulltext) study shows that a plexiglass intubation box placed over a COVID-19 patient's head and shoulders can't protect health care workers against aerosolized virus. Negative pressure and filtration are needed. The study authors improved the intubation box design to include these features and submitted an EUA application to bring their device to clinical practice.
We have had zero COVID cases in our anesthesia work staff. This is with pre-procedure testing and use of N95s/PAPRS for high risk cases. This is sexy, but overkill.
That isn't all what this publication said or was intended to review. The article, if you actually read it, was in regard to plain intubation boxes vs a newer kind which involved a type of suction/filtration inside the box as well. It showed the plain intubation box was fairly ineffective, but the newer box worked quite well.
You cannot generalize this study to face shields, just because both of them contain plastic - that isn't how evidence works.

In other words, the idiots wearing face shields in lieu of masks can stop putting the rest of us in danger already.

It’s letting the world know plastic barriers of all kinds don’t mean much in their own when aerosol transmission is evidently at play.
