Rh incompatibility is a condition that occurs during pregnancy when a woman has Rh-negative blood and her baby has Rh-positive blood inherited from the father. Rhesus factor is an antigen that exists on the surface of red blood cells in most people in blood types such as A+, O+ or A- or O-. Rh antibodies are harmless in a first pregnancy, rarely harmful. If mom gets pregnant again with another Rh positive baby, her newly produced Rh antibodies will recognize the Rh Factor proteins in her baby’s blood as a foreign invader and attack those cells. This can cause swelling and rupture of the baby’s red blood cells, if enough of the baby’s blood cells rupture, and the blood count gets too low, this condition is known as Hemolytic Disease of the Newborn.
How to Prevent and Treat Rh Incompatibility?
If a mother have been determined as Rh negative, and the father of the child as Rh positive. Administration of two doses of Rh immune-globulin(RHOGAM) injections during the first pregnancy, (28wks gestation) and the second within 72 hours of delivery. This injection acts like a vaccine, preventing the mother’s body from producing antibody.
