Rhesus conflict during pregnancy: what one need to know

B. I. Ошовський


Rhesus-conflict is a pathological condition that manifests itself in the formation of antibodies against fetal erythrocytes in the body of pregnant woman due to the incompatibility of maternal and fetal Rh-factors. The main causes of morbidity

and mortality in rhesus conflict are intrauterine hemolytic anemia, fetal hydrops, hemolytic neonatal disease. In addition, an important factor contributing to the increase in perinatal losses in this pathology is the high birth rate of extremely immature children. The reason for this is a preterm labor induction in case of a threat to the life of the fetus, as well as premature births associated with a variety of fetal manipulations. The number of cases of this pathology has declined dramatically throughout the world over the last decades, due to the widespread coverage of women at risk of immunization (anti-D - immunoglobulin). Unfortunately, in Ukraine this situation is not uncommon to this day.

The article covers the main modern views on the causes, pathogenesis, course and prevention of immunological conflict associated with incompatibility of the Rh factor in terms of evidence-based medicine. The article describes the experience gained during recent years and attempts to unify the prognostic and preventive approaches in this area.


1. Rhesus-conflict remains a serious problem of domestic medicine with a significant contribution to perinatal loss.

2. Proper and timely anti-Rh immune prophylaxis among all non-immunized women can significantly reduce the incidence of severe disease in fetuses and newborns.

3. There are no remedies for Rhesus conflict. Treatment is subjected to severe hemolytic disease only that occurs before the fetal maturity. Intrauterine hemotransfusion allows prolonging such pregnancy and preventing antenatal fetal death.
