COMPARISON OF OPERATING TABLE COVERING STYLE IN THE PROTECTION OF THE SURGICAL SITE
For the operating room with local vertical airflow in the operating zone, this paper discusses the effect of operating table covering style on minimizing the risk of contamination of the surgical site. The research includes both computational fluid dynamics (CFD) numerical simulations and experimental measurement. The Lagrangian particle transport model was used to track particle movement. The standard K- turbulence model was applied in the study to account for the influence of turbulence on particle movement. Results show that the particle concentration in the surgical site is lower at lower supply air velocity than at higher air velocity. A laminar flow regime that provides air at 0.15 to 0.20 m/s ensures that particles are not impinged on the surgical site. The experimental work was performed in an actual operating room. Numerical results and measured data show it is not feasible to cover the operating table with a sheet trailing on the floor for protecting the surgical site.
