Rh-negative mothers should be followed closely by their providers during pregnancy.

Rh incompatibility can be prevented with Rh immune globulin, as long as the medicine is given at the correct times. In Rh incompatibility, maternal IgG antibodies form after maternal exposure to fetal Rh-positive blood during birth or pregnancy-related complications (e.g., fetomaternal hemorrhage).

Prognosis. The Rh-positive fetus inside the Rh-negative mother would be treated as a foreign body, and the mother’s body would react as if the invading factor is a substance such as a virus. The disease can be avoided by vaccinating the mother with Rh immunoglobulin after delivery of her firstborn if there is Rh-incompatibility. Rh incompatibility symptoms in your unborn baby can range from mild to life-threatening.

Maternal antibodies produced in response to paternally derived D antigens on fetal red blood cells are the leading cause of severe haemolytic disease of the fetus and newborn (erythroblastosis fetalis). IgG antibodies are produced by the maternal immune system, usually against the RhD antigen.

The initial pregnancy is not affected; however, subsequent pregnancies are at risk of fetal hemolysis and, in severe cases, intrauterine hydrops fetalis. Rh incompatibility is almost completely preventable.

Rh incompatibility, also known as Rh disease, is a condition that occurs when a woman with Rh-negative blood type is exposed to Rh-positive blood cells, leading to the development of Rh antibodies. Thus, a woman who has Rh-negative blood must be treated with Rh immune globulin during and after each pregnancy or after any other event that allows her blood to mix with Rh-positive blood. The Rh vaccine destroys any fetal blood cells before the mother’s immune system can develop antibodies. Once you have formed Rh antibodies, the medicine will no longer help. Rh-positive antibodies circulating in the bloodstream of an Rh-negative woman otherwise have no adverse effects. These antibodies can freely cross the placenta, binding to and destroying RBCs. Special immune globulins, called RhoGAM, are now used to prevent RH incompatibility in mothers who are Rh-negative. Rh hemolytic disease How Rh hemolytic disease develops. For infants with ABO incompatibility, the overall prognosis is excellent. Rh incompatibility occurs when an Rh-negative mother carries a fetus with an Rh-positive blood type.
