When a patient has a high fever that does not subside, local cold therapy, such as cold towels and ice packs, can be used to dissipate heat by conduction, or whole-body cold therapy, such as warm water swabbing and ethanol swabbing, can be used to achieve the purpose of cooling. In addition, because the patient’s high fever will consume the body’s energy, attention should be paid to nutrition and water supplementation to improve the body’s resistance and facilitate the body’s recovery. 1.Warm water wipe or warm water bath: use a warm wet towel to wipe the patient’s armpits, neck, limbs, hands and feet, or take a warm bath to take away excess heat from the body and promote heat dissipation by evaporating excess water from the body surface; 2.Alcohol wipe: apply to the auxiliary cooling of patients with high fever, using 20%-35% alcohol, wipe the patient’s limbs and back. But this method is not suitable for newborns with delicate skin, because alcohol is easy to cause damage to the skin of newborns, allergies and other complications, so newborns should avoid the application; 3, ice method: ice smashed into small pieces, put in water to remove the corners, pour the ice into the ice bag to half full, flatten the ice bag, squeeze out the air in the bag with your hands, tighten the lid, and dry the water stains outside the ice bag with a dry towel. Ice bag can not be placed directly on the patient’s skin, otherwise it is easy to cause frostbite, can be wrapped in a towel, placed on the patient’s head, armpit, groin, etc., with the ice bag after 30 minutes to measure the body temperature once, such as down to 38.5 ℃ or less, you can remove the ice bag.
