Клинико-анамнестические факторы риска антенатальной смерти доношенного плода

Abstract

Introduction. Current clinical and laboratory methods for assessing the intrauterine growth of a fetus are indirect and often have a low prognostic significance. Meanwhile, the determination of risk factors of antenatal death of a full-term fetus with the assessment of their prognostic significance and the possible preventability of adverse perinatal outcome will identify ways to reduce the stillbirth rate. Aim. Determine the clinical and anamnestic risk factors for antenatal death of a full-term fetus in the Chelyabinsk region. Materials and methods. A retrospective analysis of the medical records of all cases with antenatal fetal death at 37 weeks 0 days – 41 weeks 6 days of pregnancy, registered in the territory of the Chelyabinsk region from 2019 to 2021, was carried out. Two groups were assigned: group 1 – women with antenatal death of the full-term fetus (158 patients), group 2 – women with live full-term births (50 patients). Results. Women with antenatal death of the full-term fetus statistically significantly more often lived in the city of Chelyabinsk and big cities of the Chelyabinsk region, had secondary vocational education and used to smoke tobacco; they had first or second pregnancy and first delivery. Among these women, female pelvic inflammatory diseases, hypertension, endocrine system diseases and specific infectious diseases (HIV infection, hepatitis C and tuberculosis) were statistically more common. These women had statistically more pregnancy-related complications such as hypertension without significant proteinuria; diabetes mellitus arising in pregnancy; gestational edema; false labour up to 37 full weeks of pregnancy; placental disorders; maternal care for poor fetal growth; acute respiratory infections. The following factors have a direct impact on antenatal death at full-term pregnancy: a history of hypertension, moderate pre-eclampsia, placental disorders, and fetal growth retardation. Conclusion. In the presence of risk factors directly affecting the occurrence of antenatal death of a full-term fetus, we consider it appropriate to deliver at 37 weeks 0 days – 38 weeks 0 days of pregnancy in order to reduce the risk of an adverse outcome of pregnancy.
