The antibiotics used vary depending on the site of the wound infection and are based on clinical experience with the medication. Most cases of disease are due to infection by Staphylococcus aureus, and for such wound infections it is generally recommended to treat with penicillin antibiotics. In most cases, wound infections such as those caused by appendicitis surgery are caused by E. coli and anaerobic bacterial infections, which are treated with cephalosporins or levofloxacin capsules. The best way to treat wound infections that are more common in clinical practice is to do a bacterial culture and drug allergy test, and then choose antibiotics reasonably based on the test results. These are only for common wound infections, for other wound infections, you should still go to the hospital in time to deal with the wound.
