Physical cooling is mainly through physical methods to speed up skin heat dissipation, to achieve the purpose of lowering the temperature, infants physical cooling methods include ice, warm water baths, paste fever patches, drink more warm water, reduce clothing, etc.. The main methods: 1, ice: ice pack wrapped in clean cotton towels on the top of the head, forehead, neck, armpits or groin and other dense blood vessels, so as to play a cooling effect; 2, warm water bath: a warm bath or warm towels to wipe the baby’s neck, armpits, groin and other locations rich in blood vessels, can help heat dissipation, pay attention to the water temperature control at 36-38 ℃; 3, fever patches: through the fever patches vaporize the water in the gel, evaporate the excess heat in the body, so as to achieve the effect of lowering the body temperature, usually on the forehead or the back of the baby’s neck; 4. Drink more warm water: feed the baby more warm water to help sweat and urinate, so that the metabolic waste and toxins in the body are discharged through sweat and urine, and also replenish body water in time to maintain electrolyte balance; 5. Reduce clothing and quilts: you can wear less clothes and cover less quilts by Increase the temperature difference between the body surface and the environment to cool the infant through the release of heat, but pay attention to timely increase and decrease to avoid the infant catching cold. Note: 1. Although alcohol wiping can dilate blood vessels and take away body heat when evaporating, the baby’s skin is delicate and the stratum corneum is thin, so wiping the body with alcohol can easily damage the baby’s skin and may even cause allergies, so it is not recommended to use alcohol to cool the baby; 2. If the fever does not go down, you need to seek medical advice and be guided by a doctor to take oral antipyretics and treat the original disease.
