Acute feto-maternal transfusion--diagnostic considerations.
Summary
A rare case of massive fetal blood loss occurred before delivery, indicated by fetal heart rate changes and newborn anemia. This event was linked to cord entanglement and likely a feto-maternal transfusion.
Area of Science:
- Perinatology
- Neonatology
- Fetal Medicine
Background:
- Antepartum fetal nonstress testing (NST) is used to assess fetal well-being.
- Reduced fetal movements can be a sign of fetal distress.
Observation:
- A 39-week gestation fetus exhibited a sinusoidal fetal heart rate pattern and severe decelerations during NST.
- The newborn presented with severe anemia and umbilical cord entanglement.
Findings:
- Laboratory tests, including globin synthesis studies, indicated massive feto-maternal transfusion.
- Significant fetal blood loss occurred within 24 hours prior to delivery.
Implications:
- This case highlights a rare cause of fetal anemia and distress.
- Clinicians should consider feto-maternal hemorrhage in cases of unexplained fetal anemia and abnormal NST findings.
