Both groups retrospectively were divided in two on the fact of the delivery during the experiment. For each 5-minute interval the contractile activity of the myometrium (number of uterine contractions, duration and amplitude of the one uterine contraction), functional state of fetuses and female (ECG) were evaluated Registration of the parameters was carried out simultaneously with the help of electrodes which were administrated in the myometrium, to the fetuses and females on the 28th day of pregnancy. <bold>Results</bold>: It was shown that EA influence on the myometrium contractile activity and functional state of fetuses and female depends on the female</italic><italic> delivery readiness. <bold>Conclusion</bold>: In the case of the optimal one short-term increase of the contractile activity (on the 15th minute after EA) with no significant fetal heart rate changes were observed. In the case of its absence no significant influence was revealed. Moderate female tachycardia in both groups under EA was registered more pronounced in delivery one group.</italic></p></abstract><trans-abstract xml:lang="ru"><p><italic><bold>Цель исследования:</bold> в хронических опытах сопоставить параметры сократительной активности матки у самок, ЭКГ у плодов и самок</italic><italic>кролика, получавших и не получавших эпидуральную анестезию (ЭА), в индуцированных окситоцином родах при различной степени их биологической готовности к процессу. <bold>Материалы и методы</bold>: исследование проведено в хроническом опыте на 30-й день беременности на 15 беременных самках кролика контрольной и 11 самках подопытной группы. По результатам индукции родов все самки ретроспективно были разделены на группы вступивших и не вступивших в роды. Изучали влияние ЭА бупивакаином (0,5% – 1 мл) на сократительную активность матки самок, функциональное состояние самок и их плодов в индуцированных окситоцином родах при различной степени биологической готовности животных к родам. Сократительную активность миометрия оценивали по числу маточных сокращений, продолжительности и амплитуде одного маточного сокращения за каждый пятиминутный интервал. Функциональное состояние плодов и самки оценивали по</italic><italic> изменению частоты их сердечных сокращений. Регистрацию исследуемых параметров осуществляли с помощью электродов, которые вводили в миометрий матки, в мышцы межлопаточной области плодов на 28-й день беременности. <bold>Результаты</bold>: показано, что при оптимальной готовности самок к родам после проведения ЭА отмечалось кратковременное (на 15-й мин) увеличение маточной активности, значимо не влияющее на сердечный ритм плодов. <bold>Выводы</bold>: у самок, не имевших биологической готовности к родам, проведение ЭА значимого влияния на сократительную активность матки и функциональное состояние плодов не оказывало. У вступивших в роды самок зарегистрировано более продолжительное учащение сердцебиения, чем у не вступивших в роды животных.</italic></p></trans-abstract><kwd-group xml:lang="en"><kwd>epidural anesthesia</kwd><kwd>bupivacaine</kwd><kwd>fetal heart rate</kwd><kwd>myometrium contractile activity</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эпидуральная анестезия</kwd><kwd>бупивакаин</kwd><kwd>частота сердечных сокращений у плода</kwd><kwd>сократительная активность миометрия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
