Cephalosporin powder should not be applied to wounds. Scattering cephalosporin powder directly on wounds may easily cause bacteria at the wound to react to cephalosporin resistance, or even cause the consequences of complicated infection, which is not conducive to patients’ future recovery. Therefore, it is not recommended for patients to use it. The correct operation steps for patients after the appearance of a wound are: first, ensure that the wound is clean, which is not suitable for the use of cephalosporin, and patients can treat the wound with anti-inflammatory treatment by using hydrogen peroxide and other ingredients. Second, use iodophor and other drugs to disinfect the wound, and if the patient’s wound appears more serious, the patient also needs to carry out debridement and drainage operations. More importantly, if the patient used cephalosporin powder sprinkled on the wound should promptly inform the doctor, in the future antibiotic treatment to replace the drug do not use cephalosporin for treatment to avoid affecting the therapeutic effect. Patients can be treated by taking cephalosporin or intravenous cephalosporin after the injury, and the effect is better than directly applying it to the wound externally. It is recommended to use topical antibacterial drugs: Bactroban, silver ion gel, etc.
