Children with fever, cold hands and feet, consider the following two situations: 1. Fever, body temperature is in the acute rise, due to the body’s own protective reaction, blood is concentrated in brain tissue, heart, liver and kidneys and other important organs, poor peripheral circulation of the limbs leads to cold hands and feet, toxins are not easily eliminated, the body temperature should be measured immediately, at this time, the body temperature changes quickly, should be measured frequently. If the body temperature exceeds 38.5℃, give oral Merlin or Tylenol to reduce fever, soak feet in warm water, rub the palms and feet, drink more warm water to increase blood volume and promote blood circulation, and give physical cooling at the same time. 2, the child’s central nervous development is immature, the ability to regulate body temperature is poor, the ambient temperature is low, the child’s hands and feet are exposed to the outside, the situation of cold hands and feet but the body is hot.
