Is Transducer Hygiene sufficient when Vaginal Probes are used in the Clinical Routine?
Vaginal ultrasound probes are semi-critical Group A medical products which must be disinfected following the manufacturer's instructions after every patient examination. According to the "Essential Requirements for Medical Devices (Directive 93/42/EEC, Annex I, paragraph 13)" the manufacturer's instructions for use for reusable products must contain suitable instructions for preparation processes. This presumes both an effective and material-compatible method. ⋯ It should also be noted that infection by bacteria and viruses can be caused not only by a contaminated probe, but by the ultrasound gel as well. According to studies by Heeg and Gauer 15, Buescher et al. as well as Ryndock et al., the fully automatic HLD system operated with hydrogen peroxide is currently the only validated system proven to provide HLD of ultrasound probes in a 7-minute cycle, thus suitable for application in the daily routine. Likewise it can also be presumed that this procedure also offers good material compatibility.
