При индуцированной беременности (ИБ) важнейшим неблагоприятным фактором, влияющим на перинатальные исходы, является ятрогенное многоплодие. Активное внедрение в практику методик, снижающих риск многоплодия, с одной стороны, и ведение ИБ в специализированных медицинских центрах, имеющих опыт работы с данной категорией пациенток – с другой, могут улучшить перинатальные исходы.</p></sec><sec><title>Ц е л ь</title><p>Ц е л ь . Анализ перинатальных исходов при индуцированной одноплодной и многоплодной беременности с целью оценки вклада фактора многоплодия в неблагоприятные последствия для здоровья новорожденных и его актуальности для совершенствования вспомогательных репродуктивных технологий.</p><p>М а т е р и а л ы  и  м е т о д ы . Проведено ретроспективное исследование анте-, интра- и раннего неонатального периода у 672 детей, рожденных в условиях Медицинского центра «АВИЦЕННА» (г. Новосибирск) за период с 2006 по 2015 г. Общая выборка была разделена на 3 группы: 1-я – дети, рожденные от одноплодной ИБ (n = 345); 2-я – дети, рожденные от многоплодной ИБ (n = 177); 3-я – дети, рожденные от одноплодной спонтанной беременности (ОСБ, n = 150) без бесплодия в анамнезе родителей, гравидность и паритет были равны. Использован клинико-анамнестический метод, с оценкой основных параметров состояния здоровья детей и родителей.</p></sec><sec><title>Р е з у л ь т а т ы</title><p>Р е з у л ь т а т ы . Выявлено, что при индуцированной многоплодной ИБ достоверно чаще (р &lt; 0.001) по сравнению с одноплодной ИБ диагностируются такие осложнения, как угроза прерывания и преждевременных родов, истмико-цервикальная недостаточность, преэклампсия и плацентарные нарушения. При этом в условиях специализированного центра большинство детей от ИБ было рождено доношенными, как при одноплодной (94.5 % случаев), так и при многоплодной (52.5 % случаев) беременностях. Любая индуцированная беременность относится к группе высокого акушерского риска, но своевременная коррекция осложнений значительно улучшает перинатальные исходы.</p></sec><sec><title>З а к л ю ч е н и е</title><p>З а к л ю ч е н и е . ИБ относится к группе высокого акушерского риска, который значительно возрастает при многоплодной беременности. Ведение пары с бесплодием в анамнезе в условиях специализированного центра с обеспечением преемственности на всех этапах от момента обращения в клинику до рождения ребенка позволяет, несмотря на развитие осложнений, обеспечить рождение большинства детей при доношенных сроках (как при одноплодной, так и при многоплодной беременностях) и при одноплодной беременности приводит к рождению детей, по основным показателям здоровья схожих с детьми от спонтанно возникшей беременности.</p></sec></abstract><trans-abstract xml:lang="en"><p>I n t r o d u c t i o n . In assisted reproductive technology pregnancy (ARTP), the most unfavorable factor aff ecting perinatal outcomes is iatrogenic multiple gestation. Active introduction into practice of techniques that reduce the risk of multiple pregnancy, on the one hand, and management of ARTP in specialized medical centers with experience in working with this category of patients, on the other, can improve perinatal outcomes.A i m . Analysis of perinatal outcomes in assisted singleton and multiple pregnancies in order to assess the contribution of the multiple gestation factor to adverse health outcomes for newborns, and its relevance for improving of assisted reproductive technology.M a t e r i a l s  a n d  m e t h o d s . A retrospective study of the ante-, intra- and early neonatal period was carried out in 672 infants born at the Medical Center AVICENNA (Novosibirsk) for the period from 2006 to 2015. The total sample was divided into 3 groups: 1st – infants from singleton ARTP (n = 345); 2nd – infants from multiple ARTP (n = 177); 3rd – infants from singleton spontaneous pregnancy (SSP) (n = 150) without infertility in the parental history, gravidity and parity were equal. A clinical and anamnestic method was used, with an assessment of the main parameters of the health status of infants and parents.R e s u l t s . It was revealed that complications such as threatened miscarriage and preterm labor, cervical insuffi  ciency, preeclampsia, and placental disorders are diagnosed signifi cantly more often in multiple ARTP (p &lt; 0.001) compared with singleton ARTP. At the same time, in the setting of a specialized center, the majority of infants from ARTP were full-term, both in singleton (94.5% of cases) and in multiple (52.5% of cases) pregnancies. Any assisted reproductive technology pregnancy belongs to the group of high obstetric risk, but timely correction of complications signifi cantly improves perinatal outcomes.C o n c l u s i o n . ARTP belongs to the group of high obstetric risk, which increases signifi cantly with multiple gestation. Management of an infertile couple in a specialized center with continuity at all stages from the moment of contacting the clinic to the birth of a child allows, despite the development of complications, to ensure the birth of full-term infants (both in singleton and multiple pregnancies), and in singleton pregnancies it leads to the birth of children, in main health indicators similar to those from a spontaneous pregnancy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>многоплодие</kwd><kwd>индуцированная беременность</kwd><kwd>ВРТ</kwd><kwd>перинатальные исходы</kwd><kwd>здоровье новорожденных</kwd><kwd>ЭКО</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multiple pregnancy</kwd><kwd>assisted reproductive technology pregnancy</kwd><kwd>ARTP</kwd><kwd>perinatal outcomes</kwd><kwd>newborn health</kwd><kwd>in vitro fertilization</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">Luke B.
