[Current problems of blood group incompatibility in pregnancy].

The frequency of hemolytic disease of fetus and newborn has decreased since introduction of Rh-prophylaxis. In spite of that till now hemolytic disease caused by anti-D antibodies occur. It is probably caused by immunization already during pregnancy. Therefore it seems to be useful to give anti-D-Immunoglobulin (200 micrograms = 1000 IE) in 28-30th week of pregnancy in all d-women with D-husband. This seems especially necessary in pregnancy complications as hemorrhages in 3rd trimester, multiple pregnancies, trauma, and external version of breech. Rh-prophylaxis post partum is to perform in usual manner. As done before 2 time screening for irregular antibodies in pregnancy is necessary. Amniocentesis is often required in presence of antibodies against D, C, c, E, e, K, Fya, Fyb, S, s, U, Jka, Jkb and Dia. When hemolytic disease is confirmed, intrauterine transfusion or preterm delivery has to be performed. Immunization have increasing importance against erythrocyte factors other than D. It should give attention to it in transfusion practice during pregnancy.
