There is no clinical conclusion as to how many degrees of ear temperature can be taken as fever reducers due to individual differences and influencing factors. In clinical practice, the use of ear thermometers is relatively rare because ear temperature may be affected by the external environment, and when the patient’s environment is cold or hot, it may cause the epidermis to be affected by the temperature and thus affect the measurement value. It is recommended that patients measure their ear temperature and then retest it by axillary or oral measurement to ensure accurate values. If there are other special circumstances or if the symptoms are not relieved after intervention, and if the temperature continues to rise, you can take antipyretic drugs under the guidance of a doctor. Usually patients with a body temperature of 37.3°C and above are considered febrile, but immediate use of antipyretic and analgesic drugs may interfere with temperature changes and other clinical signs in the development of the disease and mask other underlying diseases, so drug antipyretic therapy is generally not required for body temperatures below 38.5°C. If the patient’s condition is special, such as young age or poor systemic condition such as cardiac, pulmonary or cerebral insufficiency, physical cooling can be done first under the guidance of a physician, and antipyretic drugs can be taken if necessary. In case of fever, the patient can be advised to drink more water and perform physical cooling, such as using warm water baths, and pay attention to keeping the patient warm to avoid symptoms of chills. In addition, the body temperature can be lowered by applying cold compresses to the forehead, etc. If the temperature is not relieved and decreases, antipyretic drugs should be taken under the guidance of a doctor. Acetaminophen is preferred for reducing fever, which is antipyretic and analgesic and has anti-inflammatory effects. In addition, common medications such as ibuprofen and aspirin (not for infants and children) can help reduce the body temperature and alleviate the symptoms of infection and inflammation in the organism.
