Insufficient performance of cleaning and disinfection of flexible endoscopes can pose an infection risk to patients. Actually quality of reprocessing is checked by performing microbiological cultures. Unfortunately, their results are not available on the same day so that more rapid methods are desirable. We compared the ATP (adenosine triphosphate)(More)
We measured bacterial and particle concentrations at the level of operative fields during 105 operation procedures under laminar air flow conditions. Measured concentrations were at least a factor of 20 lower than in comparable rooms without ultra-clean air and laminar air flow. Kind of operation (septic/aseptic), number of participating persons and(More)
Air cooling units are said to pose a health risk to humans because of residual water and biological contamination. We measured particles 0.5 and 5 microm, ultrafine particles and bacterial counts near the outlet of 38 air cooling units and at the corresponding workplaces. Control measurements were performed in 17 rooms without air cooling units. There was(More)
