Acute infections of the hand can be a pathology with severe consequences. Alongside the surgical therapy, it is necessary to establish a systemic antiinfective therapy as well. The most frequent bacteria in acute hand infections are Staphylococcus aureus and, less frequently, different Streptococci. If the infection is the result of a bite wound, the most frequently found bacterium is Pasteurella multocida. Fortunately, the susceptibility to frequently used antibiotics in the (middle-)European area is quite good - according to the literature, resistances are rare. First line antibiotics are 1st and 2nd generation cephalosporins as well as aminopenicillins in combination with beta-lactamase inhibitors. Especially in multi-morbid patients or infections with unusual aetiology, a broader bacterial spectrum is to be expected. It is very effective to collect a tissue sample or swab for microbiological analysis before the establishment of the antiinfective therapy to gain valuable information about the prospective therapy. Ultimately, hand infections are a pathology to be treated with increased attention to avoid severe complications. A close cooperation with the involved specialties and physiotherapists should be sought to guarantee the best possible outcome., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.
