Laparoscopy has been found to result in aerosolization of blood borne
viruses and so a more cautious approach has been taken during the
pandemic and more attention given to safe deflation of the
pneumoperitoneum. We have used a heat and moisture exchange filter to
deflate the abdomen as an alternative to a smoke evacuation device.
These filters are known to reduce the transmission of microbes and other
particulate matter in breathing systems and are readily available in the
anaesthetic room.
