Different levels of bacteriological contamination were observed in two identical operating rooms served by air-conditioning systems having the same air distribution with a definite turbulent pattern.
Both rooms had practically the same occupancy rates,but in one of them dirty wound operations were performed, whereas in the other only traumatology surgery – i .e ., with clean wounds – was carried out.
The bacterial particle count readings taken over the operating table revealed, as expected, a lower contamination level in the traumatology room – never above Class 5 level as defined by the American College of Surgeons. In the operating room where dirty wound operations were performed, Class 5 level was – though not always – exceeded.
