Abstract: OBJECTIVE: To understand impacts of PM2.5 and PM10 concentrations in operating rooms from smog which was produced from electrosurgical knife usage. METHODS: 50 cases with thoracolumbar fractures who needed electrosurgical knife usage and 50 cases who did not require electrosurgical knife for vertebroplasty were selected as the observation and the control groups,respectively. Air samples in the clean laminar flow operating rooms were collected to determine PM2.5 and PM10 concentrations. RESULTS: Concentrations of PM2.5 and PM10 in the air of the observation group were significantly higher than those in the control group (P<0.05). CONCLUSION: The smog from electrosurgical knife usage was a cause of pollution in the operating rooms which posed risks of health hazards for both medical professionals and patients.
