O36.0
Maternal care for rhesus isoimmunization
Clinical Classification Guidelines
Inclusion Terms
- Maternal care for Rh incompatibility (with hydrops fetalis)
Medical Intelligence & Overview
Maternal care for rhesus isoimmunization, also known as Rh incompatibility, is a condition that occurs during pregnancy when a mother’s immune system attacks her baby’s red blood cells due to incompatibility between the mother’s and baby’s blood types. This condition can lead to serious complications such as hemolytic disease of the fetus and newborn, including hydrops fetalis, a severe, life-threatening swelling of the fetus.
Causes & Symptoms
Clinical Causes: Maternal Rh-negative blood group Fetus Rh-positive blood group inherited from father Previous pregnancies or miscarriages with Rh-positive fetuses Rh incompatibility developing during the current pregnancy if fetal blood crosses into maternal circulation
Key Symptoms: No symptoms in most Rh-negative mothers Signs of fetal anemia such as rapid heartbeat (fetal tachycardia) Hydrops fetalis, characterized by severe swelling, abnormal fluid accumulation, and skin edema in the fetus In severe cases, fetal anemia can lead to stillbirth or neonatal complications
Diagnostic & Treatment
Diagnosis Path: Blood testing of the mother to determine Rh status and the presence of maternal antibodies against Rh-positive blood Amniocentesis to measure bilirubin levels and assess fetal hemolysis Ultrasound examinations to detect signs of hydrops fetalis and fetal anemia Non-invasive fetal blood sampling methods may be considered for further assessment
Treatment Protocols: Administration of Rh immunoglobulin (RhIg) shots to Rh-negative pregnant women during pregnancy and after delivery to prevent sensitization Close fetal monitoring through ultrasounds and blood tests In cases of significant fetal anemia, intrauterine blood transfusions may be performed to treat the fetus Delivery of the baby if the condition becomes severe or when the fetus reaches full term Neonatal treatment may involve blood transfusions and supportive care after birth
