Summary
Massive fetomaternal hemorrhage can occur in normal pregnancies, presenting as decreased fetal movements. Prompt diagnosis and delivery are crucial to prevent fetal anemia and hypovolemic shock, improving neonatal outcomes.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
Background:
- Fetomaternal hemorrhage (FMH) is a rare complication of pregnancy.
- Massive FMH can lead to severe fetal anemia and distress.
Observation:
- Two cases of massive FMH (390 and 635 ml fetal blood) in otherwise normal pregnancies are presented.
- The primary maternal symptom was decreased fetal movement.
- Cardiotocography showed a severely abnormal pattern, necessitating urgent cesarean delivery.
Findings:
- The etiology of massive FMH remains unclear in these cases.
- Delayed intervention can result in fetal anemia, hypovolemic shock, and stillbirth.
- Decreased fetal movement is a critical indicator of fetal decompensation in FMH.
Implications:
- Early detection of FMH through fetal erythrocyte testing is vital.
- Immediate delivery and neonatal blood transfusion are critical for viable fetuses.
- In preterm cases, cordocentesis and intrauterine transfusion may be considered.
