Для достижения поставленной цели обследовано 35 рожениц с затянувшимся вторым периодом родов и 45 рожениц, имевших физиологические роды. Были изучены уровни прогестерона, эстрадиола, релаксина, серотонина, холестерина, продуктов, реагирующих с тиобарбитуровой кислотой (ТБКАП), общая антиоксидантная емкость плазмы, продукты конечного окисления белков, а также суммарная концентрация нитрит- и нитрат-ионов (NOx) в плазме.</p></sec><sec><title>Результаты</title><p>Результаты. При ЗВПР уровни эстрадиола и прогестерона были значимо выше, чем при физиологических родах (р1 = 0,037, р2 = 0,029). У рожениц, родоразрешенных оперативным путем, в отличие от имевших физиологические роды были более высокие уровни эстрадиола (р = 0,017) и прогестерона (р = 0,07). При ЗВПР уровень релаксина был меньше, чем при физиологических родах (р = 0,084), особенно в случае оперативного родоразрешения (р = 0,041), риск которого увеличивался в 4,1 раза при концентрации релаксина менее 36,4 нг/л. У пациенток с ЗВПР, родоразрешенных путем кесарева сечения, по сравнению с пациентками, имевшими физиологические роды, был значимо выше уровень ТБКАП (р = 0,043), а при его концентрации &gt;180,3 мкмоль/л риск кесарева сечения повышался почти в 12 раз (р = 0,003).</p></sec><sec><title>Заключение</title><p>Заключение. Гормональный аспект патогенеза затянувшегося второго периода родов характеризуется более высокими концентрациями половых стероидных гормонов: эстрадиола и прогестерона, а также более низким уровнем релаксина в плазме. Биохимический аспект патогенеза представлен увеличением концентрации продуктов ПОЛ, что в родах может отождествляться с выраженным физическим утомлением. Обнаруженные изменения могут быть применимы в комплексной диагностике и прогнозе ЗВПР.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to study the role of neurohumoral and biochemical changes in the pathogenesis of prolonged second stage of labor.</p></sec><sec><title>Material and methods</title><p>Material and methods. To achieve the above objective, we examined 35 parturient women with prolonged second stage of labor and 45 parturient women with physiological labor. We studied the levels of progesterone, estradiol, relaxin, serotonin, cholesterol, thiobarbituric acid reactive substances (TBARS), total antioxidant capacity of plasma, products of final protein oxidation, as well as the total concentrations of nitrite and nitrate ions (NOx) in blood plasma.</p></sec><sec><title>Results</title><p>Results. In the women with prolonged second stage of labor, the levels of estradiol and progesterone were significantly higher than in those with physiological childbirth (p1 = 0.037, p2 = 0.029). The women giving birth by operation had higher estradiol (p = 0.017) and progesterone (p = 0.07) levels than those giving birth physiologically. The level of relaxin was lower in the women with prolonged second period of labor than in those with physiological labor (p = 0.084), especially in the case of operative delivery (p = 0.041), the risk of which increases 4.1 times when the relaxin concentration is less than 36.4 ng/l. Compared to the patients giving physiological childbirth, the patients with prolonged second stage of labor who delivered by cesarean section had significantly higher TBARS levels (p = 0.043). Its concentration &gt; 180.3 μmol/l increases the risk of cesarean section almost by 12 times (p = 0.003).</p></sec><sec><title>Conclusion</title><p>Conclusion. The hormonal aspect of the pathogenesis of prolonged second stage of labor is characterized by higher concentrations of steroid hormones — estradiol and progesterone, as well as by a lower level of relaxin in plasma. The biochemical aspect of the pathogenesis is represented by an increased concentration of lipid peroxidation products, which can be identified with severe physical fatigue in childbirth. The detected changes can be applied in the complex diagnostics of prolonged second stage of labor.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>затянувшийся второй период родов</kwd><kwd>эстрадиол</kwd><kwd>прогестерон</kwd><kwd>релаксин</kwd><kwd>оксидативный стресс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>prolonged second stage of labor</kwd><kwd>estradiol</kwd><kwd>progesterone</kwd><kwd>relaxin</kwd><kwd>oxidative stress</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">Sherwood OD.
