[Significance of Staphylococcus aureus in nose operations. Risk of toxic shock syndrome?]

In a prospective clinical trial the pre- and postoperative presence of S. aureus was examined in 130 patients undergoing nasal septal surgery. The patients were randomized into three groups. The first group received no perioperative antibiotics, the second group was given oral amoxicillin plus clavulanic acid, while the third group was treated with oral sulfamethoxazol and trimethoprim. A significant decrease in the incidence of S. aureus was observed in post-operative cultures, but the difference was not attributable to the antibiotic use. Overall, 18.9% of the S. aureus carriers harbored toxic shock syndrome toxin-1 positive strains. However, the decrease in the presence of S. aureus and the risk for toxic shock syndrome was not influenced by the antibiotics administered. These findings show that the routine use of oral prophylactic antibiotics for patients undergoing nasal surgery seems not indicated.
