[Fetomaternal blood incompatibility: the situation in 1983]

56 cases of allo-immunization were collected over a period of 4 1/2 years, i.e. 4.3 per 1 000 births. The authors analyse the aetiologies of these cases of allo-immunization and the therapeutic indications for the more severe cases. They discuss the indications for plasmapheresis, in utero transfusion and premature extraction of the fetus. Five deaths were recorded from this series of 56 births.
