In clinical practice, there is no such thing as the best septic and draining drug, and the most effective treatment for abscess formation is incision and drainage to adequately reach the bottom of the abscess cavity and retain some of the pus, send it for bacterial culture and drug sensitivity testing, and select sensitive antibiotics according to the drug sensitivity results. With adequate drainage, anti-infective treatment is used to avoid systemic inflammatory response syndrome so that effective treatment can be achieved. The use of drugs alone does not achieve the best therapeutic effect when the pus is not able to drain adequately.
