What to do if a child has a high fever of 40°C

High fever mainly refers to hyperthermia. A high fever of 40°C in children may be caused by physiological factors, bacterial infection, or viral infection, and can be managed through general care or medication. The specific analysis is as follows:

I. Physiological Factors

If proper warmth is not maintained, children may catch a chill, leading to high fever. Under a doctor's guidance, medications such as ibuprofen suspension, acetaminophen suppositories, or pediatric paracetamol-phenylephrine granules may be taken orally. It is also important to stay warm and avoid exposure to cold.

II. Pathological Factors

1. Bacterial Infection

Children have relatively weak immune systems and are highly susceptible to external pathogens, such as bacteria. When the infection is severe, it can trigger the body to produce large amounts of pyrogens, generating excessive heat that cannot be effectively dissipated, resulting in high fever. Treatment may include oral administration of azithromycin tablets, amoxicillin capsules, or ibuprofen granules under medical supervision.

2. Viral Infection

When a large number of viruses invade the body, inflammatory factors may excessively proliferate, impairing the regulation of the body's temperature center and causing high fever. Medications such as Yinqiao Jiedu tablets, oseltamivir phosphate capsules, or celecoxib capsules may be taken orally as prescribed by a physician.

Besides the above causes, lobar pneumonia and other pathological conditions may also lead to high fever. It is essential to seek prompt medical attention at a hospital to determine the underlying cause and receive appropriate treatment.
