3 Questions
What is Hemolytic Disease of the Newborn?
A condition where the mother's blood type is Rh-negative and the fetus is Rh-positive
How can Hemolytic Disease of the Newborn be prevented during the first pregnancy?
Administering a single dose of anti-Rh antibodies during the postpartum period
What is Kernicterus?
A condition where bilirubin penetrates the brain causing brain damage in the newborn.
Study Notes
- Hemolytic Disease of the Newborn occurs when an Rh-negative mother carries an Rh-positive fetus.
- Fetal blood can leak into the maternal circulation during delivery, causing the mother to develop anti-Rh agglutinins.
- During the next pregnancy, the mother's agglutinins can cross the placenta to the fetus and cause hemolysis.
- Hemolysis can lead to anemia, severe jaundice, edema, and Kernicterus in the newborn.
- Sensitization of Rh-negative mothers by carrying an Rh-positive fetus generally occurs at birth.
- Hemolytic disease occurs in Rh-positive fetuses born to Rh-negative mothers who have previously been pregnant with Rh-positive fetuses.
- Administering a single dose of anti-Rh antibodies during the postpartum period can prevent sensitization from occurring the first time.
- Fetal Rh typing with material obtained by amniocentesis or chorionic villus sampling is now possible.
- Treatment with a small dose of Rh immune serum can prevent sensitization during pregnancy.
- Bilirubin penetrates the brain more easily in infants due to the blood-brain barrier being more permeable and the bilirubin-conjugating system not yet being mature.
