1. Rhesus Blood Grouping and Pregnancy This presentation explores the inheritance of Rhesus (Rh) blood groups and its implications for pregnant mothers. We'll discuss Rh incompatibility, potential complications, treatment options, and monitoring strategies. by Kawuma Martin

2. Understanding the Rh Factor Rh-Positive Individuals with Rh-positive blood have the Rh protein on their red blood cells. Rh-Negative Individuals with Rh-negative blood lack the Rh protein on their red blood cells.

3. Rh Incompatibility and Pregnancy Complications Rh-Negative Mother, Rh-Positive Fetus When a Rh-negative mother carries an Rh-positive fetus, the mother's immune system may perceive the fetal Rh protein as foreign and produce antibodies.

4. Maternal Antibody Formation and Fetal Risks First Pregnancy Typically, the first pregnancy with an Rh-positive fetus is uneventful. However, the mother's body develops antibodies. Subsequent Pregnancies In subsequent pregnancies with Rh-positive fetuses, the maternal antibodies can cross the placenta and attack the fetal red blood cells.

5. Treatment Options for Rh Incompatibility Rh Immunoglobulin (RhIg) RhIg is a medication that prevents the mother from producing antibodies. It's given to Rh-negative mothers during pregnancy and after delivery. Monitoring and Management Close monitoring of the mother's blood and fetal health is crucial to identify and address potential complications.

6. Rh Immunoglobulin (RhIg) Administration During Pregnancy RhIg is typically administered at 28 weeks and again after delivery if the baby is Rh-positive.

7. Monitoring and Management During Pregnancy 1 Ultrasound Regular ultrasounds monitor fetal growth and development. 2 Blood Tests Blood tests measure antibody levels in the mother's blood.

8. Conclusion and Key Takeaways 1 Rh Incompatibility 2 Prevention 3 RhIg Administration 4 Monitoring 5 Safe Pregnancy

9. Rh Incompatibility Treatment: A Closer Look 1 D-Antigens Rh-positive blood cells have D-antigens. 2 Anti-D Antibodies RhIg contains antibodies specific to D-antigens. 3 Binding Anti-D antibodies bind to fetal D-antigens.
