For febrile patients with a body temperature of 38°C, you can first try symptomatic treatment with physical cooling. For example, warm water can be used for a full-body bath and diluted alcohol can be used for a local bath. At the same time, ice packs or cold packs can be used to cool the forehead of the patient locally. When using cold packs, it should be noted that the cold packs should be changed for a period of time to prevent the patient from developing frostbite due to continuous cold packs. While giving the patient physical cooling, it is also necessary to let the patient pay attention to rest. Next, it is necessary to replenish enough water to prevent the patient from losing water during the fever. It is necessary to monitor the body temperature closely, usually every half hour to one hour, to retest the body temperature, so as to understand the effect of the patient’s fever reduction. If the body temperature continues to drop, antipyretic treatment can be stopped when the patient’s body temperature returns to normal.
