Aerosol Production with Surgical Instrumentation: Implications for Head and Neck Surgery in the COVID-19 Era
Abstract Evaluating the aerosolization of droplets from surgical instruments to assess the implications of surgery in SARS-CoV-2 transmission for both patients and providers. Cadaver study. Outpatient surgery center. Aerosolized particles between 0.3 and 25 microns were measured. Instruments tested included monopolar cautery with and without suction, bipolar cautery, a bipolar vessel sealing device, and tissue scissors. Each trial was compared to a background reading. Monopolar cautery without suction, Ligasure used continuously and Bipolar cautery produced the most aerosols. Monopolar cautery with simultaneous suction produced no detectable aerosols. Ligasure used for a single cycle produced notably fewer aerosols than during continuous use. Most aerosols produced were < 5 microns. These data support n95 use during surgical management of the upper aerodigestive tract, as well as the use of suction in the surgical field..
