Statistics from

During this COVID-19 pandemic, at increased risk of infection are clinicians involved in aerosol-generating procedures such as endotracheal intubation.1 We herein describe a technique to mitigate aerosolisation. As shown in the figure 1A, the rubber bung of a 20 mL syringe plunger is used to occlude the connector of the endotracheal tube (ETT) figure 1B, preventing aerosolised particles (eg, during coughing) from being directed towards the operator. Once the ETT tip has passed the larynx and its cuff has been inflated to ensure seal, a clamp is applied to the ETT (not shown) prior to removal of the …
