[Aerodynamic analysis of a new sterile operating enclosure, and comparative bacteriologic testing between a conventional operating theatre and a sterile enclosure during sham operations (author's transl)].

An aerodynamic and bacteriological evaluation of a new sterile operating enclosure has been undertaken, comparing it with a conventional operating theatre under sham operating conditions with or without coincident use of either a surgical helmet or surgical face mask. Statistical analysis of these studies show the bacterial level in the sterile enclosure at the wound site is significantly lower than in ordinary operating theatre conditions whereas the use of a helmet with evacuating ducts effects these findings insignificantly.

[Test methods for surgical hand disinfection (author's transl)].

As exemplified by a test preparation, methods for assessing the effect of hand disinfection on the resident flora are put up for discussion. The test of a method for hand disinfection must make allowance for conditions prevailing in practice. Accordingly, the following steps should be taken into consideration: A. Single use 1. Immediate disinfecting effect 2. Duration of the disinfecting effect B. Repeated use 3. Course of the initial colony count 4. Immediate disinfecting effect 5. Behaviour of colony count after interruption of the disinfecting method applied. For the purpose of comparing the total count, as with all other disinfecting methods, the colony count must be determined by fractional collection methods; to this end, Traub's procedure may be modified, possibly using the plastic bag method described by Gaschen. A careful statistical evaluation with appropriate transformation of the results is indispensable.
