[Handling Sterile Materials and Medications in Anesthesia and Functional Areas].

Bacterial contamination at the anesthesia workstation is common and correlates with an increased rate of postoperative infections. This article emphasizes the importance of strict hygiene regulations in anesthesia and functional areas to prevent nosocomial infections. It summarizes scientific findings and practical recommendations for minimizing contamination of work areas, instruments, and medications. Important measures include organizing the anesthesia workplace into "clean" and "unclean" areas, using hand disinfectants, wearing disposable gloves, and disinfecting hand contact surfaces. Special recommendations apply to invasive procedures such as central venous catheterization and regional anesthesia. The "one-hour rule" for preparing medications is critically discussed and translated into a practical approach for providing repeated medications during a procedure. A case study shows the application of these principles in a knee TEP revision. Mechanical cleaning and disinfection of surfaces at the end of the case and reprocessing of medical equipment by qualified personnel are also important aspects.
