Newborns should not have been infected with any diseases in such a short period of time after birth, but many people have found that their babies have developed fever. Newborns with fever can make their mothers very anxious, and many parents hope to find the cause as soon as possible and take active measures. What should I do if a newborn has a fever for 15 days?
Reasons for newborn fever
Newborns, especially premature infants, are highly sensitive to infections, which can be severe and often lead to fever, pneumonia, or sepsis. This is determined by the anatomical, physiological, and immune characteristics of newborns.
1. Newborns have insufficient defense function and incomplete barrier function. In the early postnatal period, the navel has not yet healed, and the skin and mucous membranes are delicate and easily damaged, becoming a gateway for bacterial invasion. In addition, newborns have low immune function, which can easily lead to fever.
2. The phagocytic ability of neonatal multinucleated white blood cells is poor, and their bactericidal effect on bacteria is also lower than that of adults.
3. There are many invasive pathways for systemic bacterial infections in newborns, and the causes of infection are complex, which can occur in utero, during labor, and postpartum.
What should I do if a newborn has a fever
1. Fever caused by environmental factors: By appropriately lowering the ambient temperature (the suitable room temperature for newborns is 22-25 ℃), releasing the blanket or adding more water, the baby's body temperature can be reduced to normal.
2. Fever caused by disease factors: It is best for parents to promptly take their baby to the hospital for examination. During the transfer, the baby needs to be wrapped less, and a cold water bag can be placed on the head. When the body temperature exceeds 39 ℃, you can first give a warm water bath or warm water wiping bath at home, with a water temperature of 33 ℃ -35 ℃, and the wiping areas are the forehead, limbs, groin, and armpits. Avoid using alcohol for bathing to prevent a sudden drop in body temperature, even below 35 ℃, which can have adverse effects.
