Fetal haematology in rhesus isoimmunisation.
نویسندگان
چکیده
Haematological studies were carried out in pure fetal blood samples obtained fetoscopically in 29 rhesus isoimmunised pregnancies at 18-24 weeks' gestation, and the values were compared with those obtained in 62 normal control pregnancies. Fetal reticulocytosis or erythroblastaemia was seen only in association with a haemoglobin concentration of 4 g/dl or less. Ten of the 14 fetuses with a haemoglobin concentration below 4 g/dl showed ultrasonographic evidence of hydrops.

In other conditions associated with placental oedema-such as the fetofetal transfusion syndrome, and hydrops fetalis due to rhesus isoimmunisation or congenital syphilis-low levels of the maternally synthesised immunoglobulin IgG have been found in the cord bloods of the infants.7 8 These findings suggest that placental transfer ofIgG is also reduced. We, like Chiang and Wei,7 found that the co...
