does an RH neg patient need a rhogam shot just because she is pregnant?

Описание: RhoGAM is a solution of antibodies, collected from plasma donors. Your doctor is prescribing RhoGAM because you are Rh-negative. During pregnancy, it is normal for a small amount of the baby’s blood to enter your bloodstream. When the blood from your Rh-positive baby enters your Rh-negative bloodstream, there will be a blood type mismatch. This is called Rh-incompatibility. Your immune system sees the baby’s red blood cells as “foreign” and will produce antibodies that try to eliminate them. RhoGAM, if given to you at the right time, will prevent your immune system from reacting to your baby’s blood. RhoGAM is made from human blood and may carry a risk of transmitting disease-causing agents.
RhoGAM prevents the Rh-negative mother from making antibodies during her pregnancy. As long as the Rh-negative mother receives RhoGAM appropriately during every pregnancy, her babies are at very low risk of developing hemolytic disease of the fetus and newborn (HDFN).

When will I receive RhoGAM?

Your doctor will administer at least one dose of RhoGAM Ultra-Filtered PLUS between 26 and 28 weeks of pregnancy. If your baby is found to be Rh-positive at birth, you will receive an additional dose within 72 hours after delivery. Your doctor will determine the appropriate dose of RhoGAM after delivery.

You should also receive RhoGAM after abdominal trauma, obstetrical manipulation or an invasive procedure (such as amniocentesis, chorionic villus sampling or percutaneous umbilical blood sampling), maternal or fetal bleeding during pregnancy or an ectopic pregnancy (pregnancy in which the fertilized egg implants outside the uterus). RhoGAM should also be considered after a threatened pregnancy loss or pregnancy termination. The dose and dosing schedule will be determined by your doctor.
