When the baby is born, one of the first manipulations that will be done to him is the measurement of body temperature. Normally, the indicators on the thermometer will be 0.1-0.6 degrees different from the temperature of his mother's body. And all because the temperature in my mother's stomach is higher than outside. It will literally be 60 minutes, as the body temperature of the newborn begins to fall. And in 2-4 hours will reach its minimum marks.
A sharp drop in temperature is provoked by the immaturity of the thermoregulation system of the newborn and the new conditions for the existence of crumbs, to which it still needs to adapt. Healthy babies do not lose more than 1.5-2.5º C, but premature babies or those born after severe intrauterine hypoxia can tolerate a "drop" of up to 35º and even 32º C. This condition creates a threat to life, so these babies are nursed in special kuvezah Under the hood.
After the temperature reaches its lowest values, it will start to grow gradually, and after 12-24 hours it will reach 37º C. If the indices during this time interval did not rise to 36ºC, it signals a weakened protective forces of the organism. Such babies are subject to a more thorough examination by specialists - neonatologists of Kiev.
On the 3-4th day after birth, it is possible that such a phenomenon as an abrupt increase in temperature to 40 ° C. This occurs mainly at night, lasts 3-4 hours and completely disappears. This condition is called "transient fever of newborns." The child's well-being does not suffer at all, except that he can refuse to eat. At the same time, there is also a peak in the maximum physiological loss of weight of crumbs (up to 10% of the initial mass from birth).
Pediatricians noted that strong babies, who lose less than 200 g of initial weight, almost never encounter transient fever. But the kids who lost from 500 to 720 g, in half of the cases experience its symptoms. The explanation is simple: these babies lose more fluid, and their first food is colostrum, contains a large amount of protein, which requires a sufficient amount of liquid for normal digestion. A strong protein load provokes a temperature rise. Such a baby is enough to just give it a drink, so that all the indicators come back to normal.
