“…However, although the 30 mL amount is significant in the prevention of Rh sensitization; it does not correlate with the risk of fetal morbidity or mortality. The threshold for a large feto-maternal hemorrhage (FMH) was established at 80 or 150 mL [ 20 ]. According to the literature, the incidence of an FMT of 30 mL was estimated to be approximately 3 per 1000 births [ 18 , 20 , 21 , 22 , 23 ].…”

In our study, we investigated the rate of fetal RBCs, which translated into the volume of FMT, in different groups of women, and not just the incidence of large FMH.…”

Background: The aim of the study was to investigate if feto-maternal transfusion was related to the size of the fetal-maternal interface, and, therefore, was larger in twin pregnancy in comparison with singleton pregnancy. Methods: Blood samples from women with singleton (n = 11), and monochorionic (n = 11) and dichorionic (n = 13) twin gestations were tested. Flow cytometry tests with hemoglobin F, glycophorin A, and hemoglobin F and carbonic anhydrase simultaneous staining were used to detect fetal red blood cells and maternal F cells. Results: In all cases, the volume of feto-maternal transfusion was estimated to be low. The highest rate of fetal red blood cells in the maternal circulation was observed in the blood of women with dichorionic twin gestations both before and after delivery. An increase in fetal red blood cells was observed after cesarean section in singletons and twins. The median rate of maternal F cells was 2.23% in singleton, 2.1% in monochorionic and 3.95% in dichorionic pregnancy. Conclusions: Feto-maternal transfusion during pregnancy may be related to the multiplicity and chorionicity of pregnancy.

“…The most widely used test remains the Kleihauer-Betke test. Other methods are flow cytometry and liquid chromatography [14][15][16]. Depending on the obtained result, the fetal blood volume lost into maternal circulation can be estimated according to Mollison's formula: (percentage of fetal erythrocytes × 1800)/100 × 1.22 = mL of fetal blood [17].…”

Severe Neonatal Anemia Due to Spontaneous Massive Fetomaternal Hemorrhage at Term: An Illustrative Case with Suspected Antenatal Diagnosis and Brief Review of Current Knowledge

Fetomaternal hemorrhage is defined as transfer of fetal blood into placental circulation and therefore into maternal circulation during pregnancy, and represents an important contributor to intrauterine fetal demise and neonatal death. The condition is rarely diagnosed prenatally because clinical findings are often nonspecific, and it is unpredictable. In this paper we present an illustrative case of massive spontaneous fetomaternal hemorrhage where the diagnosis was highly suspected antenatally based on maternal reported reduced fetal movements, abnormal suggestive cardiotocographic trace, and increased peak systolic velocity in the fetal middle cerebral artery. We discuss obstetrical and neonatal management and review the current knowledge in the literature. Maintaining a high index of suspicion for this condition allows the obstetrician to plan for adequate diagnostic tests, arrange intrauterine treatment or delivery, and prepare the neonatal team.
