Drug-resistant bacterial infections should be treated with sensitive antibiotics. If the infection is severe, carbapenem antibiotics can be used first to control the condition and then treat it gradually. Drug-resistant bacterial infections refer to bacteria that have been in contact with certain antibiotics for a long period of time, leading to a decrease in sensitivity to the antibiotics used first, and then losing their therapeutic effect. In this case, bacterial culture and drug sensitivity tests are recommended so that sensitive antibiotics can be selected to treat the infection. Common antibiotics include penicillin, erythromycin, azithromycin, clarithromycin, gentamicin and ofloxacin. Apart from that, if the infection is more serious and has affected the patient’s life, carbapenem antibiotics such as meropenem and ertapenem should be used in time in order to control the condition quickly. However, after the condition improves, the drug dose should be reduced as early as possible to avoid damage to the body. Drug-resistant bacterial infections are not essentially different from non-drug-resistant bacterial infections in terms of clinical manifestations. However, due to the reduced sensitivity to certain antibiotics, the treatment is relatively more difficult. Therefore, after diagnosis, it is important to follow the doctor’s instructions and treat the infection as soon as possible. Drugs should be used under the guidance of a professional physician, and should not be used arbitrarily on their own.
