### output:

Hallow Dear, Rh -ve mother and Rh’ve father is a combination where the child may get affected. Usually baby of the first pregnancy is not affected if there is no bleeding during pregnancy. After the first delivery, some blood from the baby leaks into mothers blood and the antibodies to the Rh’ve cells are formed. These antibodies in subsequent pregnancies enter the baby in the uterus and start killing babies red cells if the baby is Rh’ve. If the mother is not given protection, each subsequent baby gets affected more and more.  Therefore, after each delivery antigammaglobulin injection needs to be given to prevent the antibody formation in the mothers blood. The first affected baby of second pregnancy develops severe jaundice due to destruction of red cells in large number. Such babies require exchange blood transfusion. Subsequent babies are affected earlier and earlier while in uteri. The extent of damage in the mothers blood is assessed by Indirect Combs test which measures the title of the Rh antibodies in the mothers blood. Depending upon the title, the mother is given injection of Rh antigammaglobulin and the baby may be given blood transfusion while in uteri. I think I have simplified the complicated topic for your understanding to the most. If you need detailed information about this, you may ask me Direct question by going to my profile.
