Antipyretic injections are not recommended for 1-year-olds with recurrent high fevers. In addition to symptomatic cooling treatment, cause-specific treatment is also important for temperature recovery. Fever is one of the most common symptoms in pediatrics, and appropriate antipyretic methods, such as physical hypothermia and oral medications, should be chosen according to the degree of elevated body temperature of the child. Fever-reducing injections, known as lysergic acid for injection, should be used with caution in children and are contraindicated in infants under 3 months of age. Children may develop Reye’s syndrome after using the drug. Therefore, antipyretic injections are generally not recommended. Generally for children with fever but body temperature <38.5 ℃ can use lukewarm water on the child's forehead, reduce the clothing worn and other physical methods to lower the temperature, and encourage the child to drink more water, some children's temperature can gradually decline; for children with body temperature ≥38.5 ℃ need to use antipyretic drugs such as ibuprofen, acetaminophen and other antipyretic treatments under the guidance of a doctor. At the same time, it is also important to treat the cause of the disease. If the respiratory tract infection caused by bacterial infection, need to actively use antibacterial drugs such as cefaclor, cefdinir and other anti-infection treatment. If it is a rheumatic immune disease, immunosuppressant treatment is needed; if it is a blood tumor-related disease, chemotherapy, bone marrow transplantation and other treatments are needed. All of the above drugs should be used under the guidance of a doctor, avoid self-medication. There are many causes of recurrent high fever in children, and it is recommended to consult a specialist for evaluation and treatment.
