Prevention of post-operative infections after surgical treatment of bite wounds

After reviewing the literature about the microbial spectrum, the risk factors of post-operative infections, and the results of surgical interventions, the following recommendation can be made for the management of bite wounds:FRESH, OPEN WOUNDS: surgical debridement, if appropriate, then an antiseptic lavage with a fluid consisting of povidone iodine and ethanol (e.g., Betaseptic(®)), no antibiotics, primary wound closurenearly closed fresh wounds (e.g., cat bites): surgical debridement, if appropriate, dressing with an antiseptic-soaked compress for ~60 minutes with repeated soaking (e.g., Betaseptic(®)), no antibioticsolder wounds after ~4 hours: surgical debridement, if appropriate, dressing with an antiseptic-soaked compress or bandage for ~60 minutes with repeated soaking (e.g., Betaseptic(®)), at the same time intravenous or dose-adapted oral antibiotics (Amoxicillin and/or clavulanic acid)older wounds after ~24 hours: surgical debridement, then antiseptic lavage (Betaseptic(®)), in case of clinically apparent infection or inflammation surgical revision with opening of wound and treatment with antibiotics according to resistogram (empirical start with Amoxicillin and/or clavulanic acid).For each kind of bite wound, the patient's tetanus immunization status as well as the risk of exposure to rabies have to be assessed. Similarly, the possibility of other infections, such as lues (Syphilis), hepatitis B (HBV), hepatitis C (HBC), hepatitis D (HDV) and HIV, in the rare case of a human bite wound, has to be taken into account.
