[Fetomaternal hemorrhage: a series of 9 cases]
Aim:
This study was designed to stress the importance of early diagnosis of fetomaternal hemorrhage (FMH) in attempt to prevent the subsequent adverse outcome on the fetus and the newborn.
Patients And Methods:
Nine newborns were admitted because of neonatal anemia to our neonatal unit from October 1989 through September 1995. The diagnosis of FMH was made by the sigma diagnostic fetal hemoglobin that is the Kleihauer test in our hematologic laboratory. Other causes of neonatal anemia have been ruled out.
Results:
Seven out of the nine cases have expressed early signs of fetal distress in term of abnormal fetal monitoring and/or thick meconium associated with decreased fetal movements. At birth, a wide clinical spectrum depending on the amount of the hemorrhage was seen, ranging from mild anemia with no symptoms (four cases), hypovolemic shock (one case), respiratory distress syndrome (two cases) and maladjustment to extra-uterine life (one case). There was one death at 48 hours after birth; one infant survived with severe encephalopathy.
Conclusion:
These results indicate that it is mandatory to carry out a Kleihauer test whenever a high suspicious index of FMH is faced or an unexplained neonatal anemia is found.
