Hdn involves multiple steps that happen at different times throughout pregnancies.
At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Ultrasound - to detect organ enlargement or fluid buildup in the fetus. First, a sample of fetal RBCs is washed to remove any unbound antibody Ig. The direct Coombs test see below confirms the presence of anti-D and hence that the mother has been sensitized. Also write down any new instructions your provider gives you for your child. Know why a new medicine or treatment is prescribed and how it will help your child.

Intravenous transfusion under ultrasound guidance via the umbilical vein is to be preferred to the intraperitoneal route, as the latter is more difficult in an hydropic fetus and causes more complications. For a summary of transfusion reactions in the US, see reference. The placenta may be thickened. Placenta praevia Placental insufficiency Twin-to-twin transfusion syndrome. Respiratory Intrauterine hypoxia Infant respiratory distress syndrome Transient tachypnea of the newborn Meconium aspiration syndrome pleural disease Pneumothorax Pneumomediastinum Wilson—Mikity syndrome Bronchopulmonary dysplasia.
Antibodies to the other Kell antigens are rare. The incompatible antigens introduced result in a primary immune response and stimulate the production of maternal antibodies.

This test can show enlarged organs or fluid buildup in your baby. When red blood cells breakdown, this makes your baby anemic. The risk of future sensitization can be greatly reduced by giving all unsensitized mothers anti-D Ig, which "mops up" any fetal RBCs that may have leaked into the maternal circulation, reducing the risk of first-time exposure to the D antigen. Usually, Rh D-negative mothers receive on injection of anti-D Ig at about 28 weeks gestation, which is about the time when fetal RBCs start to express the D antigen, and mothers receive another dose at about 34 weeks, a few weeks before labor begins during which the risk of fetomaternal hemorrhage is high. Know why a new medicine or treatment is prescribed and how it will help your child. HDN happens when an Rh negative mother has a baby with an Rh positive father. This is done by placing a needle through the mother's uterus and into the abdominal cavity of the fetus or directly into the vein in the umbilical cord.
