Kids Physiologic versus Pathological Neonatal Jaundice

Hi all:

There are some criteria concerning neonatal pathological jaundice:

a.) jaundice appears < first 24 hours of life

b.) bilirubin rises > 5~8 mg/dL in 24 hours

c.) the rate of bilirubin > 5mg/dL/day

For points b.), can someone please tell me that they are talking about indirect bilirubin or total bilirubin? Thank you!


BTW, anyone reading BRS pediatrics? I am reading BRS pediatrics and just curious how many people here are also using this old book.

Physiologic Jaundice

1-Visible jaundice appearing after 24 hours of age.
2-Total bilirubin rises by < 5 mg/dL (86 mmol/L) per day.
3-Peak bilirubin occurs at 3–5 days of age, with a total bilirubin of no more than 15 mg/dL (258 mmol/L).
4-Visible jaundice resolves by 1 week in the full-term infant and by 2 weeks in the preterm infant.

So, if total bilirubin rises > 5~8 mg/dL in 24 hours => pathological!

btw,

"3-Peak bilirubin occurs at 35 days of age, with a total bilirubin of no more than 15 mg/dL (258 mmol/L)."

some books say (e.g. Nelson) 12 mg/dL in term babies and 15 mg/dL in preterm babies....
