Surgical smoke, neurosurgical practice and coronavirus

This is the authors' abstract. We don't add key points for this paper.

Surgical smoke also referred to as cautery smoke is a gaseous mixture produced during surgical procedures where there is ablation, cutting, coagulation, desiccation or vaporization of the tissue. In a true sense "surgical smoke” refers to surgically generated gaseous contents. The surgical smoke results from the destruction of bones and tissues, causing microscopic particles to get suspended in the environment.
