[Value of systemic and local administration of antibiotics in soft tissue and bone infections].
There is little data to support the efficacy of prophylactic antibiotics in traumatology. In closed fractures three randomized controlled studies using a 1-3 day prophylaxis with Cephalosporins of the first or second generation or a Penicillinase-resistent Penicillin demonstrated a reduction of the infection rate. For the Cephalosporins of the second generation it was shown, that a single dose was less efficient than five repeated applications over 24 hours. In hip-fractures a prophylaxis with Cephalothin or Cefotiam reduced the frequency of infections when compared with controls. In open fractures a treatment over 10 days using Cephalothin or Isoxazolyl-Penicillin showed a significant drop of the infection rate. If however the fractures were not treated using the principles of rigid internal fixation and were covered with Dicloxacillin over 2 days only there was no significant improvement. A multicenter study finally indicates that a one day course of cefonicid sodium is not inferior to a prolonged course of antibiotics for prevention of early postoperative fracture-site infections. We conclude, that open and closed fractures can profit from antibiotic prophylaxis which starts immediately before surgery and is continued over 24 hours. We favour Isoxazolyl-Penicillin because of its efficacy against staphylococcus aureus and epidermidis which predominate in early infection. In established bone and soft tissue infections antibiotics are used when there is local spreading, sepsis, involvement of joints or when reinterventions in the infectious focus are necessary. In these cases bacteriological testing in the laboratory is essential for the selection of antibiotics. Local application of antibiotics in irrigation-drainage solutions can not be recommended. PMMA-chains serve as temporary spacers, but should be removed early before their extraction becomes difficult and resistant bacteria develop. When defects are closed with cancellous bone or soft tissues the use of Gentamycin-fleece or Taurolin-gels is recommended.
