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.
在两个具有不同建筑预设的手术科室中，对卫生标准进行了检查。在临床B的有利条件下（霍施过滤器、水闸系统），可检测到的细菌相对频率为55%。在临床A中，由于缺少这些条件，该频率为80%。在非病原菌中，DNase阴性葡萄球菌的检出频率高于其他细菌。分别有13.4%和18.9%的细菌是DNase阳性葡萄球菌。我们使用产气荚膜梭菌来检测细菌的侵入途径。最重要的途径是窗户漏水、空调和水闸系统不足。对消毒效果进行了检查。其波动范围为67%至100%。一次对照的效果为42%。结果表明，为普通手术科室建立无菌房间是不可能的。但结果也表明，没有水闸系统和适当的空调，就无法达到令人满意的卫生标准。
