This condition is characterized by maternal immunoglobin G antibodies destroying the red blood cells (RBCs) of the neonate or fetus, resulting in potentially life-threatening consequences. When a mother with an Rh-positive blood group has a fetus with an Rh-negative blood group, the fetal RBCs trigger maternal antibodies against Rh-antigens. Anti-D antibodies are activated as a result of this process, which is known as isoimmunization. As a result of the antibody reaction, all of the erythrocytes are destroyed, resulting in hemolysis, bilirubin release, and anemia. Intravascular transfusions and intraperitoneal transfusions are examples of antenatal therapies that potentially avoid dangers to the fetus in the early stages of pregnancy. Phototherapy, exchange top-up transfusions, and intravenous immunoglobulin (IVIG) injections are examples of postnatal therapies (IVIG). IVIG therapy is highly recommended since it has a low risk of adverse medication responses and a wide range of survival rates. To avoid isoimmunization, anti-Rh D therapies are indicated.
