Study Notes
Normal Values and Risk Factors
- Normal values for unconjugated bilirubin are 0.3-1.4 mg/dL
- Breastfeeding is NOT a risk factor for neonatal jaundice
Phenobarbital and Jaundice Management
- The main purpose of using Phenobarbital is to increase the conjugation of bilirubin and enhance its excretion
Characteristics of Jaundice
- Jaundice appearing after 72 hours of age is associated with sepsis
- Physiological jaundice in newborns is mainly caused by the breakdown of fetal hemoglobin
- A characteristic feature of pathological jaundice in newborns is jaundice that appears within 24 hours of birth
- Physiological jaundice is distinguished from pathological jaundice by the timing of onset, severity, and underlying cause
- Hyperbilirubinemia in neonates is defined as a total serum bilirubin level >2.5 mg/dL
Neonatal Characteristics
- Neonatal jaundice is characterized by yellow discoloration of the skin and mucous membranes
- Vernix caseosa refers to a thick, cheesy substance that covers the skin of newborns
- Acrocyanosis is commonly associated with cold stress in newborns
