Abstract :

Infection control is an important discipline concerned with prevention of nosocomial infections and in prevention of surgical site infections. Infections can spread through any means like blood, oral fluid, other secretions, surfaces, instruments, air etc. The most intangible means of pathogen transmission is air. The HEPA (High–efficiency particulate air) filter is capable of removing 99.97 percent of all particles larger than 0.3 microns in diameter. However the effect of HEPA filter on reducing the existent room air microbial burden takes time. In this study we analyzed how much time it takes for the HEPA filter to act in order to achieve a nil growth on culture plate. We were able to achieve nil growth on culture plate by 30 minutes hence emphasizing the need to switch on the HEPA filter half an hour prior to surgery for maximum benefits in prevention of surgical site infections.
