Summary
Rh immunisation in pregnancy requires monitoring via amniocentesis. High bilirubin levels, indicated by the Liley diagram, necessitate interventions like corticosteroids and potentially infant exsanguinotransfusion.
Area of Science:
- Perinatology
- Maternal-Fetal Medicine
- Neonatology
Background:
- Rh immunisation poses a significant risk during pregnancy, potentially leading to hemolytic disease of the fetus and newborn (HDFN).
- Monitoring fetal well-being is crucial in Rh-immunized pregnancies to guide timely interventions.
Observation:
- Amniocentesis was performed in 42 pregnant women with Rh immunisation (56 procedures).
- Liley diagram assessment identified high delta bilirubin extinction in the B zone (6 cases) and A zone (16 cases).
Findings:
- In cases with high delta bilirubin extinction in the B zone, immunosuppressive therapy with corticosteroids was administered.
- All cases with high delta bilirubin extinction in the B zone and those in the A zone ultimately required neonatal exsanguinotransfusion.
Implications:
- This study highlights the critical role of amniocentesis and Liley diagram interpretation in managing Rh immunisation.
- Aggressive management, including corticosteroids and neonatal exchange transfusion, is often necessary for severe cases of HDFN.
