Neonatal thermoregulatory center is not well developed, coupled with insufficient heat production, large body surface area, rich blood vessels, thin subcutaneous fat layer easy to dissipate heat, such as improper warmth is easy to get cold, newborns with cold may appear poor response, poor sucking power, and in severe cases, respiratory distress, cold injury syndrome, etc. For newborns with cold should pay sufficient attention to take the following measures: 1, rewarming: increase the ambient temperature to 24 ~ 26 degrees Celsius, reduce heat dissipation in newborns, maintain normal body temperature, such as limited conditions, you can use hot water bags wrapped in towels to ensure that the temperature of the bedding, also available hot bed, electric mattress, or even the mother’s arms, the conditions should be placed in the incubator. Note that rewarming should be carried out gradually and progressively. 2, nutritional support: according to the baby’s sucking power, digestive situation to choose the appropriate nutrition supply, conducive to the baby’s body temperature recovery. 3, prevention of infection: the newborn’s body resistance decreases after the cold, it is easy to respiratory system infection and gastrointestinal and digestive system infection, pay attention to give protective isolation, do a good job of environmental, air disinfection, avoid contact with too many people. 4, close observation: closely observe the baby’s vital signs and the baby’s cry, reaction, general state, urine volume, etc. All these conditions should be observed to prevent the occurrence of neonatal cold injury syndrome. The above are the specific measures taken by the clinical common neonatal cold, newborn cold is different from other people’s cold, sometimes there will be frostbite syndrome, serious cases can be life-threatening, the emergence of such cases in time to seek medical treatment.
