Smoke Evacuation in the OR
The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) and the European Association for Endoscopic Surgery (EAES) have recently published Recommendations regarding Surgical Response to COVID-19 (https://www.sages.org/recommendations-surgical-response-covid-19/). In order to reduce the risk of virus spread with carbon dioxide (CO2) during laparoscopy, the use of devices to filter the released CO2 is recommended.
The SARS-CoV-2 RNA virus has been reported to have a size of 0.06-0.14 microns1 (HIV virus 0.12 microns2, HPV virus 0.055 microns3, hepatitis C 0.06 microns4). Ultra low particulate air (ULPA) filters have been proven to capture airborne particles down to 0.1 microns at 99.999% efficiency. However, based on the published data on HIV viruses, HPV and hepatitis C, the capture of even sub-0.1 micron particles is possible.
As it employs a ULPA filter, the OLYMPUS OR-VAC Smoke Evacuator can help to mitigate possible infectious transmission associated with exposure to surgical smoke during surgery.
A complete elimination of risk is however not possible.
