tailieunhanh - Evaluation of microbial contamination using various air sampling techniques in operation theatres

Microbial contamination of the Operation theatres (OT‟s) continues to increase the prevalence of nosocomial infections. Our study evaluates the microbial contamination using various air sampling techniques in OT‟s and find a suitable technique to assess air quality. A total 151 air samples were collected from various OT‟s of our tertiary care samples were collected by an active method using an air slit sampler and 75 samples were collected by passive settle plate method using 5% Sheep blood agar in 9cm petri-plates. The mean microbial count of the both active and passive sampling method in OT‟s was colony forming units (CFU)/m3 and CFU/m3 respectively. In most OT‟s CFU/m3 were in normal limits. The labor OT at rest, exceeded the maximum limit value of active method | Evaluation of microbial contamination using various air sampling techniques in operation theatres
