Возникновение дистресса плода требует проведения экстренного оперативного родораз решения, что может сопровождаться увеличением числа акушерских осложнений. Цель. Оценить прогностическую значимость комплексной оценки стандартных параметров первого скрининга и объема амниотической жидкости на сроке беременности 11–13+6 недель для стратификации риска экстренного оперативного родоразрешения, выполненного по поводу дистресса плода. Материалы и методы. Проведено пилотное обсервационное исследование 103 беременных, которое начиналось на сроке 11–13+6 недель беременности и заканчивалось непосредственно после родоразрешения. Исследование носило наблюдательный характер и включало не только стандартный скрининг первого триместра, но и расчет объема амниотической жидкости. На основании исхода родов было сформировано 2 группы: 82 беременные составили группу контроля, 21 пациентка, вошедшая в основную группу, была родоразрешена оперативным путем в связи с развитием дистресса плода. Для стратификации риска применялась бинарная логисти ческая регрессия. Оценка прогностической способности модели проводилась с помощью ROC-анализа и критерия Хосмера-Ле мешоу. Результаты. Одномерный анализ выявил наличие тенден ции к различиям исследуемых групп на сроке 11–13+6 недель бе ременности по следующих параметрам: толщина воротникового пространства плода (p = 0,17), стандартизованный объем амниотической жидкости (p = 0,1), уровень свободной бета-субъединицы хорионического гонадотропина человека (p = 0,22). Модель бинарной логистической регрессии, включающая указанные потенциально значимые показатели, обладает значимой информативностью (ROC-AUC = 0,722 ± 0,067 [95 % CI 0,591–0,854], Se = 68,4 %, Sp = 72,5 %, p = 0,003). Заключение. Модель, интегрирующая в ходе проведения первого скрининга оценку толщины воротникового пространства плода, уровня свободной бета-субъединицы хорионического гонадотропина человека и отношения объемаам ниотической жидкости к сроку гестации, обладает достаточной прогностической ценностью и может быть использована для стратификации риска экстренного оперативного родоразрешения пациенток по поводу дистресса плода.</p></abstract><trans-abstract xml:lang="en"><p>Fetal distress is the most common cause of stillbirth, hypoxic ischemic encephalopathy, cerebral palsy, and neonatal mortality. Fetal distress requires emergency operative delivery, which may be accompanied by an increase in obstetric complications. Aim. To evaluate the prognostic value of the comprehensive assessment of standard parameters from the first screening and amniotic fluid volume at 11–13+6 weeks of pregnancy for risk stratification of emergency operative delivery due to fetal distress. Materials and methods. The pilot observational study of 103 pregnant women was conducted, beginning at 11–13+6 weeks of gestation and ending immediately after delivery. The study was observational and included not only standard first trimester screening but also amniotic fluid volume assessment. Two groups were formed based on the delivery outcome: 82 pregnant women were assigned to the control group, while 21 patients in the study group underwent operative delivery due to fetal distress. Binary logistic regression was used for risk stratification. The predictive ability of the model was assessed using ROC analysis and the Hosmer-Lemeshow test. Results. Univariate analysis revealed the trend toward differences between the study groups at 11–13+6 weeks of gestation for the following parameters: nuchal translucency thickness (p = 0.17), standardized amniotic fluid volume (p = 0.1), and free beta-subunit human chorionic gonadotropin level (p = 0.22). The binary logistic regression model including these potentially significant parameters demonstrated significant statistical significance (ROC-AUC = 0.722 ± 0.067 [95 % CI 0.591–0.854], Se = 68.4 %, Sp = 72.5 %, p = 0.003). Conclusion. The model integrating assessment of fetal nuchal translucency, free beta human chorionic gonadotropin levels, and the ratio of amniotic fluid volume to gestational age during the first screening has sufficient prognostic value and can be used to stratify the risk of emergency cesarean delivery in patients with fetal distress.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дистресс плода</kwd><kwd>экстренное кесарево сечение</kwd><kwd>первый триместр беременности</kwd><kwd>толщина воротникового пространства</kwd><kwd>хорионический гонадотропин человека</kwd><kwd>объем амниотической жидкости</kwd><kwd>прогностическая модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fetal distress</kwd><kwd>emergency cesarean section</kwd><kwd>first  trimester of pregnancy</kwd><kwd>nuchal translucency thickness</kwd><kwd>human  chorionic gonadotropin</kwd><kwd>amniotic fluid volume</kwd><kwd>prognostic  model</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Silvestro S., Calcaterra V., Pelizzo G., Bramanti P., Mazzon E.
