fetomaternal hemorrhage

Fetomaternal transfusion The passage of blood from the placenta–via the umbilical cord into the mother at the time of delivery; FH has considerable importance in Rh-negative ♀ who deliver Rh-positive babies, against whom the mother may form antibodies, possibly resulting in 'rejection' of the fetus in subsequent pregnancies, with–in extreme cases—hydrops fetalis

fetomaternal hemorrhage

Abbreviation: FMH
The transfer of fetal blood cells through the placenta into the maternal circulation, usually at the time of delivery. Less than 1 ml is considered normal, but greater than 30 ml, as in trauma or placental abruption, is a major cause of fetal morbidity and death. The condition often occurs during pregnancy and may result in the immunization of the mother against Rh antigens in the fetus, esp. when the mother is Rh-negative and the child is Rh-positive. See: Kleihauer-Betke test

Fetomaternal hemorrhage can begin any time from the mid-first trimester onwards.
Massive fetomaternal hemorrhage (>150 ml) [in this case 140 ml] occurs in 0.12 to 0.5% of pregnancies.
Evaluation and management of the less severely traumatized patient should focus on examining the patient for placental abruption and accompanying fetomaternal hemorrhage and uterine contractions.
Maternal cells containing HgF have variable staining characteristics, depending on the pH of the Kleihauer-Betke test reagents.[19] Although subject to interpretive error, and often unreliable in the average laboratory, the Kleihauer-Betke test is still considered to be the best test to screen for and quantitate fetomaternal hemorrhage.[4,14,19]
