Physiological jaundice of newborn is a determined by the characteristics of neonatal bilirubin metabolism, physiological phenomena must occur, rather than from any other disease factors causing the jaundice.
How to tell if jaundice is rational?
First, note the jaundice appears at: usually occurs about 3 days after birth, a few to see slight yellowing of the skin on the second day after birth, or delay occurred to 5 days after birth. Gradually increased in the future, typically in jaundice di2-3 days after the most obvious.
Extent of jaundice: mainly rely on the determination of serum bilirubin to the judgment. Physiological jaundice of the highest value is the Moon should not exceed 12mg%, should not exceed 15mg% in preterm infants. Is the first from scleral jaundice in the order, face, neck and then spread to the trunk and limbs. Parents can jaundice appears part of a rough estimate of lycopene concentration in the blood, only in the face and neck to see jaundice, blood concentrations of red pigment from about 6-8mg%; spread to the upper body, approximately 9-12mg%; spread to lower body, about 12-16mg%, the palms and soles are yellow, generally above the 15mg%.
Development of jaundice speed: Although the extent of jaundice does not exceed the normal range of bilirubin, but appears earlier, faster development, prompt may also have a serious disease. Jaundice speeds also depend on the development of determination of serum bilirubin to judge. Normal is a month of neonatal cord blood bilirubin up to 2.5mg%, within 24 hours after birth than 6mg%,48 hours not exceeding 7.5%, within 72 hours of not more than 12mg%.
Jaundice retreat time: term infants jaundice dissipated 7-10 days of general health, no more than 2 weeks after birth at the latest, may be delayed until after birth in preterm infants 3-4 weeks back the net, if jaundice receded more than normal time, or stand back and returns are not working properly.
Other: a physiological jaundice of newborn apart from jaundice, other aspects are normal, such as infants, sleep, cry, urinary and fecal discharge, temperature, etc.
In short, the judgment is a physiological jaundice on people\'s livelihood should be based on jaundice of newborn began dissipated, the extent, development speed, and time and the total of all aspects of it are normal to judgment. General after successfully, do not need to be treated.
