Learning Objective 1: understand number of stool and urination point to some degree (prediction) of bilirubin

Learning Objective 2: understand that there is an inverse proportion between the bilirubin value and the number of stool and urination.

Discharging healthy term newborns from the hospital after delivery at increasingly earlier postnatal ages has recently become a common practice for medical, social, and economic reasons. However, newborns whose post delivery hospital stay is less than 72 hours are at a significantly greater risk for readmission than those whose stay is more than 72 hours. Hyperbilirubinemia is the most commonly reported cause for readmission during the early neonatal period. Healthy term newborns discharged after 72 hours of life with no more than mild hyperbilirubinemia may even develop a subsequent moderate to severe hyperbilirubinemia. Jaundice occurs in most newborn infants and some degree of jaundice is normal and probably not preventable. Because of the potential toxicity of bilirubin, newborn infants must be monitored to identify those who might develop severe hyperbilirubinemia and, in rare cases, acute bilirubin encephalopathy or kernicterus. Bilirubin production typically declines to the adult level within 10 to 14 days after birth. Normally, the excessive bilirubin can be removed from the body in the stool and in the urine. Early detection of high bilirubin can prevent rare, but serious, complications from high bilirubin levels in newborns. In this study, the relation between the values of urination and stool frequency and the total serum bilirubin values in the newborns with hyperbilirubinemia was investigated. Method Healthy term newborns, who are hospitalized for jaundice without any infection or illnesses, were followed prospectively with daily serum total bilirubin measurements, stool and urinalysis. A correlation between the total serum bilirubin values and the stool and urine frequency was studied. Conclusion In this study, we therefore concluded that the number of stool and urination point to some degree (prediction) of bilirubin and there is an inverse proportion between the bilirubin value and the number of stool and urination.
