      <abstract xml:lang="ru">
        <p>Для оценки воздействия вирусной инфекции COVID-19, перенесенной на поздних сроках гестации, на показатели фетоплацентарного комплекса и течение беременности проведен ретроспективный анализ обменных карт пациенток Симферопольского клинического родильного дома № 2, инфицированных во II или III триместре вирусом SARS-CoV-2. Установлено триместр-зависимое влияние инфекции COVID-19 на беременность: во II триместре COVID-19 ассоциируется с более тяжелым течением заболевания у матери и вызывает выраженные нарушения в системе маточно-плацентарного кровообращения, развитие плацентарной дисфункции (по данным допплерометрии), у плода выявляются патологические изменения кардиотокограммы (снижение вариабельности ритма, поздние децелерации); в III триместре указанное заболевание в большей степени связано с развитием акушерских осложнений, а нарушения плацентарной функции менее выражены, чем у инфицированных во II триместре. Для данной категории пациенток целесообразно внедрение персональных протоколов мониторинга с расширенным использованием допплерометрии и кардиотокографии с целью своевременного выявления доклинических нарушений.</p>

        <p>To assess the impact of COVID-19 infection in late pregnancy on fetoplacental complex parameters and the course of pregnancy, a retrospective analysis of medical records of patients registered at Simferopol Clinical Maternity Hospital No. 2, who were infected with SARS-CoV-2 in the second and third trimesters, was conducted. A trimester-dependent impact of COVID-19 infection on pregnancy has been established. In the second trimester, COVID-19 is associated with a more severe course of the disease in mothers and causes significant disturbances in the uteroplacental circulation system, the development of placental dysfunction (according to Doppler ultrasound data), and abnormal cardiotocogram changes in the fetus (decreased heart rate variability and late decelerations). Infection in the third trimester is more closely associated with the development of obstetric complications, while placental dysfunction is less pronounced than in those infected in the second trimester. For this category of patients, it is advisable to implement personal monitoring protocols with the expanded use of Doppler ultrasound and cardiotocography in order to promptly identify preclinical disorders.</p>
