Patients with high fever are usually treated with a combination of medication and physical cooling, usually when the patient’s body temperature exceeds 38.5°C. The commonly used drugs include oral ibuprofen and acetaminophen non-steroidal drugs. For patients who cannot cooperate with oral drugs, diclofenac sodium and Chaihu injection can also be used for antipyretic treatment, while warm water can be used to rub the patient’s whole body or diluted alcohol can be used for local rubbing. At the same time, you can use cold compresses for local cold compresses and ice packs for local antipyretic cooling. When using ice packs for cooling, you need to change the cold compresses at intervals to prevent prolonged local cold compresses from causing skin frostbite and other conditions, and retest the body temperature every half hour to observe the effect of antipyretic.
