It is time for a more cautious approach to surgical diathermy, especially in COVID-19 outbreak: A schematic review

Many surgeons are unaware of the risks posed by the surgical diathermy. Apart from the numerous chemicals, surgical smoke had been shown to harbour intact bacterial and virus particles especially COVID-19 in the current time.

To identify the inhalational, infectious, chemical, and mutagenic risks of surgical smoke and suggest evidence-based hazard reduction strategies. Also to cogitate on the very high risk of viral spread by the use of surgical diathermy in COVID-19 outbreak.

A review of articles indexed for MEDLINE on PubMed using the keywords surgical smoke, diathermy, electrocautery, surgical smoke hazards, smoke evacuator, and guidelines for surgical smoke safety was performed. The review included evidences from 50 articles from the dermatology, surgery, infectious disease, obstetrics, and cancer biology literature.

There are risks associated with surgical smoke. Although some surgeons were aware, majority were not keen in the hazard reduction strategies.

Many chemical and biological particles have been found in surgical smoke. It is highly recommended to follow the standardised guidelines for surgical smoke safety. Surgical smoke carries full virus particle(such as COVID-19 virus), it is strongly recommended to minimise or avoid electrocautery during the COVID-19 outbreak.
