There is no best way to eliminate anaerobic bacteria. The main thing is to destroy or eliminate the environment in which anaerobic bacteria grow and reproduce, and the common methods are drug treatment and surgical treatment. 1. Drug treatment: commonly used drugs are metronidazole, clindamycin and norethindrone vancomycin and other antibacterial drugs, which have certain effect on the treatment of anaerobic bacteria. In addition tetanus anaerobic infection, tetanus antitoxin can be used to neutralize the toxin and control the progress of the disease. When anaerobic infection occurs in superficial skin and mucous membrane, hydrogen peroxide solution can be used for rinsing to destroy the anaerobic environment and eliminate anaerobic bacteria. 2. Surgical treatment: The purpose of surgical treatment is mainly to destroy the anaerobic environment and increase the supply of oxygen. It includes incision, debridement, drainage and decompression of local lesions, removal of necrotic tissues or ineffective cavities, flushing with hydrogen peroxide solution, as well as resection of coexisting malignant tumors, removal of obstruction, thrombus, and so on. When anaerobic infections occur, the injured area should be promptly exposed, traveled to a hospital, and treated to eliminate the anaerobic bacteria.
