PurposeFocus on hygienic management in ambulances is presented based on findings from hygienic microbiological sampling.MethodsIn 44 ambulances, the handwashing area, equipment for artificial respiration, insufflation, intubation, aspiration, intravasal catheterisation, blood-pressure measurement, and sterile materials storage were examined hygienically and microbiologically using the following methods: water sampling, imprint technique, and swab technique with subsequent cultivation on blood-, endo-, and Sabouraud agar.ResultsThe highest contamination was found in the hand-washing area and on insufflation equipment (up to > or = 100,000 cfu/ml), where proof of the potential pathogens Pseudomonas, Acinetobacter, and Alcaligenes spp. was found. The second highest contamination level was found on the sphygmomanometer cuffs, stethoscopes, and respirator masks (e.g., Enterococci and S. aureus were identified). Apparently, the germs chiefly originate from the drinking water at the handwashing station, from the environment and mucous membranes from the skin, and intestines of the ambulance personnel. The predominant hygienic deficiensies were found in the equipment of the handwashing areas, and in the storage of resuscitation equipment and sterile materials.ConclusionsBased on the results of hygienic microbiological analysis, the main focus of hygienic measures--besides hand disinfection--should be on spray disinfection of the sphygmomanometer cuffs and stethoscopes as well as disinfection of ambulance equipment and storage areas for sterile devices, supplemented by dust protection of ready-to-use materials and devices. Stationary dispensers for hand disinfection possessing at least midlength levers must become the standard in ambulances, and conventional handwashing basins with plastic drinking-water containers and pump must be eliminated entirely.
