[Investigation of the hygienic standard in two hospitals including the control of disinfection (author's transl)].
In two operative departments with different architectural presuppositions, the hygienic standard was checked up. Under favourable conditions in clinic B (Hosch-filter, sluice-systems) the relative frequency of demonstrable bacteria amounted to 55%. In clinic A, where these conditions failed, it amounted to 80%. Among the non pathogenic bacteria DNase-negative staphylococci were demonstrated more frequently than others. 13.4% and 18.9% resp. of the bacteria were DNase-positive staphylococci. We used Clostridium perfringens for detecting invasion-paths of germs. The most important ones are leaky windows, air conditioning and insufficient sluice-systems. The success of desinfection was examined. It fluctuates from 67% to 100%. One control amounted to 42%. The results show, that it is impossible to establish sterile rooms for common operative departments. But they show as well that a satisfying hygienic standard cannot be arrived without sluice-systems and appropriate air conditioning.
