Abstract:
Surgical plume (SP) carries biological risks such as virus transmission. An evacuation system can remove SP from the surgical field, but is it safe to release evacuated gas into the operating room (OR) atmosphere? We examined this using a commercially available evacuator equipped with a filter under a laparoscopic porcine surgery model. SP was generated by activating an electrocautery or ultrasonic scalpel on the surface of the liver, and we evaluated whether DNA fragments derived from porcine tissue were present in the exhausted gas from the evacuation system into the atmosphere. DNA fragments were detected in the inlet gas of the evacuation system, while it was not detected in the outlet gas. As far as pathogen transmission via SP in the abdominal cavity is concerned, if the smoke evacuator ensures filter adsorption, it seems that there is little risk in releasing the suction gas into the atmosphere in the OR.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
