If a junior high school student has a fever of 39℃, which is considered high fever, it is recommended to immediately go to the hospital for blood tests and C-reactive protein, and use the right medication according to the infection to avoid affecting or delaying the condition. At the same time, physical antipyretic methods can be applied, such as wiping with warm water on the patient’s head along the brow bone to the temple, or wiping along the bilateral internal carotid arteries on the heart of both hands and both palms, and insisting on wiping 3 times a day for 10-15 minutes each time to reduce fever. Non-steroidal anti-inflammatory drugs can be applied to reduce fever, such as indomethacin, compound aminobarbital, and para-aminosalicylic acid, all of which can have the above-mentioned effects, and Advil, Advil, and ibuprofen can be applied. Physical cooling aids can also be applied, such as forehead antipyretic patches or anal application of antipyretic suppositories. You should also drink more warm boiled water, more than 1000ml on top of the regular water intake, which can relieve the high fever in junior high school students.
