Abstract:
BACKGROUND: To date, several options for helping pregnant women with rhesus immunization are known: (a) active tactics in carrying out methods of efferent therapy in the form of basic operations (plasmapheresis, hemosorption) in combination with adjuvant methods (immunoglobulin, blood photomodification with ultraviolet, laser beams, ozone therapy) to pregnant women; (b) wait-and-see active tactics with observation of the pregnant woman, followed by intrauterine intravascular transfusions of washed donor red blood cells; (c) mixed active tactics with a sequential combination, alternation of these methods. In Russia, only option 2 with fetal transfusions of washed donor red blood cells is accepted as the basis and paid for. The objective of the study is to conduct a comparative analysis of pregnancy outcomes in women with rhesus immunization using different management options. MATERIALS AND METHODS: A total of 392 women were followed up at seven different institutions in Russia and at the Donetsk Center for Maternal and Child Health (DNR), of whom 345 pregnant women (Group 1) received efferent therapy, 33 women (Group 2) had fetuses intrauterine bypass surgery, and 14 pregnant women (Group 3) had mixed efferent therapy and fetal PEEP bypass surgery. RESULTS: The analysis showed that the most favorable results for the main clinical indicators (premature, operative delivery, fetal hypoxia at birth, etc.) were in Group 1 and 3 women, in which the perinatal mortality was 14.5/1000 and 0/1000, respectively, which was significantly lower than in Group 2 (176.5/1000). It was also found that in Groups 2 and 3 women, the mean intervals between repeated transfusions of washed donor red blood cells were 8.8 0.2 and 21.4 3.8 days (p 0.01), which may be explained by the detoxifying effect of efferent therapy methods, preservation of fetal red blood cells and transfused donor red blood cells to the fetus with prolonged gestation and obtaining healthier and more viable progeny. CONCLUSIONS: 1. Severe Rh conflict is a manifestation of a syndrome of systemic effects of aggressive metabolites of specific and nonspecific nature. 2. The etiopathogenetic measure in the prevention and treatment of HDF/HDN in rhesus conflict is efferent therapy methods for the mother, and transfusion of washed donor rhesus-negative red blood cells to the fetus is effective, but a temporary, palliative measure, as is the case in multiple organ failure. 3. In the treatment protocols, efferent therapy methods must be present to prevent fetal red cell destruction and, equally importantly, to prevent destruction of Rh-negative donor red cells transfused to the fetus.
