Generally for patients with anaerobic infections, if the anaerobic infection is in the body surface area, the wound needs to be opened, such as by cutting the wound open and draining it, and draining the pus. In addition, local attention is paid to disinfection by wiping with hydrogen peroxide followed by rinsing with saline or distilled water and disinfection with iodophor covered with sterile excipients or band-aids. If the infection is more inflammatory or special bacterial infection, then in addition to the above treatment, it is also necessary to perform hyperbaric oxygen therapy in the hyperbaric chamber, which is generally more effective for anaerobic bacteria or special bacterial infection. In the infusion of antibiotics, it is recommended that the patient first take local secretions, do bacterial culture and drug sensitivity test, preferably according to the results of drug sensitivity test, and then consider the application of sensitive antibiotics. Generally, you can choose metronidazole antibiotics, as well as aminoglycoside antibiotics, as well as macrolide antibiotics, as well as vancomycin and desmethylvancomycin and other antibacterial drugs for active treatment.
