| 요약2 | Recent studies have revealed that surgical smoke emitted during laparoscopy surgery would contain hazardous contaminants. The objective of this study is to predict surgical smoke’s concentration in surgical staff‘s breathing zone in a hospital operating room, in order to estimate the potential inhalation risk of surgical smoke. To predict the surgical smoke’s concentration in the surgeon’s breathing zone, CFD (computational fluid dynamics) simulation was conducted with smoke emission scenarios including various smoke emission velocities, temperatures, and locations. The results showed that the discharge temperature of the smoke was insignificant effects on surgical smoke’s concentration distribution in the surgical staff’s breathing zone, while the discharge velocity significantly effects on the surgical smoke’s concentration distribution. When the surgical smoke emission velocity was 10 m/s with 32℃ of temperature, the highest normalized concentration was found to be 15.1?10-3 at the surgeon 1 breathing zone, and 0.1?10-3 at the surgeon 2 breathing zone. In addition, the benzene mass concentration in the breathing zone was estimated and compared with the reference concentration suggested by CalEPA. |
