Both ultrasonic and electrosurgical devices have the propensity to create large surgical plumes thus potentially increasing the risks of viral transmission. Recent NHS pandemic Coronavirus Infection Prevention and Control guidance states that high speed surgical devices generate aerosol (DHSC, 2020). Ultrasonic devices are high frequency oscillating devices which may hypothetically add to the potential risk although the magnitude of any such risks are unknown (Zheng et al., 2020).
