Early delivery: for RH negative pregnant women with previous history of blood transfusion, stillbirth, abortion and delivery, the titer of RH antibody in this pregnancy gradually increased to 1:32 or 1:64 or above. The increase of bilirubin in amniotic fluid measured by spectrophotometer and the L / S ratio of amniotic fluid > 2 indicate that the fetal lung is mature and can be delivered early.
