isoimmunization,
Rh sensitization,
hemolytic disease of the fetus.

Hemolytic Disease of the Newborn (HDN
Antibodies can attack Rh-positive fetuses in future pregnancies.
Subsequent Pregnancies
Early detection via ____helps prevent HDN.
blood testing
Occurs when a small amount of fetal blood enters the mother’s bloodstream, causing her immune system to produce antibodies against Rh-positive blood
Sensitization
Risk Factors for Sensitization
delivery
amniocentesis
vaginal bleeding,
trauma,
miscarriage
oxygen deficiency in fetal organs
erythroblastosis

Lethargy
Grading Severity: HDN
- Mild: Mild jaundice
- Moderate: Pronounced jaundice, require phototherapy
- Severe: anemia, require exchange
transfusions.
Long-term Complications if Untreated: HND

Fetal Monitoring
○ Uses ultrasound and Doppler studies to check what
