Antibiotic prophylaxis in orthopedics-traumatology

In a comprehensive analysis conducted by French author Jeannot Gaudias, the latest guidelines and consensus statement recommendations concerning antibiotic prophylaxis (ABP) for orthopedic and trauma patients are thoroughly examined. The proven effectiveness of ABP is primarily observed in hip and knee arthroplasty procedures, as well as in the internal fixation of proximal femoral fractures. However, the application of ABP in other cases does not have a solid evidence regarding its efficacy.
One fundamental aspect of ABP revolves around ensuring that the antibiotic is present at the surgical site prior to the onset of contamination. This principle serves as the cornerstone of ABP practice. To achieve this, a minimum interval of 30 minutes should be allowed between the administration of the antibiotic and the incision. This interval is particularly crucial for cephalosporins, as it provides sufficient time for their distribution into deep joint and bone tissues. For vancomycin, which is currently recommended at a dosage of 30 mg/kg, slow administration (1 g/h) is advised. It is worth noting that the half-dose reinjection should be scheduled based on the number of half-lives counted from the initial injection, rather than from the time of incision. The original article also provides a detailed overview of antibiotic usage in cases involving open fractures, providing valuable insights into this specific application.
