title: [Synthetic ultrasound blocks and contact gels in sonography: hygienically satisfactory?].
abstract: Different sponge-like plastic blocks and several samples of two coupling gels used during small-parts real-time sonography were investigated microbiologically. Whereas the coupling gels showed no contamination a great deal of different bacteria could be found on the plastic blocks. These findings lead to a restricted use of those devices especially when investigating immunocompromised patients. Sufficient procedures of decontamination do not exist. Because of the relative high purchase cost the one-way use of plastic blocks is uneconomical.
