[Perioperative antibiotic prophylaxis in allo-arthroplasty].

Since 1984 the perioperative prophylaxis was carried out using the antibiotics Oxacillin or Halospor in artificial joint replacement of the hip. We started with 1 g Oxacillin at the very beginning of the anaesthesie. Further 0.5 g Oxacillin were administered 2 and 6 hours later. 964 hip joints operated between 1982-1988 were followed up. We observed a marked decrease of the rate of infection from 7.2% to 1.0% after the introduction of the perioperative prophylaxis.
