Burns infused with anti-inflammatory drugs or fever may be wound infection, but may also be caused by sepsis. 1. Wound infection: local tissue damage after burns will produce a large number of wounds, which will lead to damage to the skin barrier, the body’s resistance is significantly reduced, which will allow a large number of pathogenic bacteria to reproduce in the wounds, resulting in a local wound infection, and fever in the body. 2. Septicemia: the pathogenic bacteria infected after burns invade the human blood circulation system, multiply in the blood circulation system, produce a large number of toxins, thus causing systemic infection. This situation can be treated with cefoperazone sulbactam combined with levofloxacin, and attention should also be paid to providing nutritional support to the body. Since there are various causes of fever after burns, it is important to check in time to find out the specific cause and actively cooperate with the doctor for diagnosis and treatment.
