XXXX draping and staff clothing in the operating theatre: a microbiological study.

@entity1 @entity7502 @entity2708
Fallout of bacteria and contamination at the wound site were studied during a standardized orthopaedic operation using sedimentation plates and a bacterial sampler. The procedure was performed in either a conventionally ventilated operating theatre or in an ultraclean air enclosure. The staff was dressed in either an all- @entity2708 system (working clothes and theatre gown) or @entity2708 working clothes in combination with Ventile theatre gown, or a laminate disposable theatre gown, or finally a @entity7502 coverall and a laminate theatre gown. The @entity1 were draped in @entity2708 or laminate. The study was done during 5 periods. The most striking effect was seen when the combination of the coverall and the laminate theatre gown was used. The fallout in the conventional theatre was then at the same level as in the ultraclean air. It was even less than using Ventile gowns and laminate drapes in ultraclean air. The contamination at the wound site showed the same pattern. However, least contamination was recorded when laminate gowns and laminate drapes were used in ultraclean air.
