Air bacterial isolations from operation theatres in a tertiary care hospital in India 87-89
Peroperative bacterial contamination of the wound is known to be a major risk factorfor surgical wound infection. The microbiological quality of theatre air is one of the significant parameter for controlling surgical wound infection. The present study was conducted in seven operation theatres of a tertiary care teaching hospital of capital city of India with 1000 beds for a period of one year. Settle plate method was adopted using standard sized Blood agar plates. A total of 344 samples taken repeatedly from seven different operation theatres were processed and the isolates were Staph aureus (16%), Coagulase negative Staph(26.7%), Acinetobacter spp.(2.03%) and Klebsiella spp. (0.3%). Crowding of surgical theatres by surgical staff, trainees and students is an important issue along with design, ventilation problems and overuse of theatres. This is the first Indian study conducted in order to determine air bacterial isolates in operation theatres.More studies are warranted on quality of air in operation theatres.
