Transplacental hemorrhage during spontaneous and induced abortions
Abstract
PIP: Blood smears were examined for the presence of fetal cells in 122 women who had spontaneous or induced abortions in an effort to determine the incidence and magnitude of fetomaternal hemorrhage after abortion. Smears from cord blood of newborn infants served as positive control smears. The amount of fetal blood that had crossed the placental barrier was determined before and after spontaneous and induced abortions in the 1st and 2nd trimester of pregnancy. The incidence of fetomaternal hemorrhage was 2.9% in the 1st trimester and as high as 11.1% in those cases who showed signs of choriodecidual disruption as in threatened abortions. The incidence was slightly higher in 2nd trimester as 6.2% in symptomless cases; it was significantly higher, 22.7%, in cases presenting with vaginal bleeding. The incidence was more in patients who had undergone surgical intervention. In the induced abortion too, the cells score percentage was higher following operation, although it was less as compared to spontaneous abortions.
