简要总结

In the event of suspected osteoarticular material infection (OAMI), broad-spectrum probabilistic antibiotic therapy is recommended immediately after revision surgery. There are no efficacy data to suggest that any particular to favour any particular molecule. However, the choice may depend on the impact on the microbiota and on Enterobacteriaceae colonization with multi-resistant Enterobacteriaceae. Our aim is to evaluate three different strategies efepime+daptomycin C+D, piperacillin-tazobactam+daptomycin (PT+D) and ceftobiprole (CFB).
