Doppler study is one of the main methods for assessing the condition of placental blood circulation and fetal hemodynamics. Doppler blood flow in the uterine arteries demonstrates the broad capabilities of the method for predicting pregnancy complications such as gestosis, fetal development delay, preterm birth, as well as for diagnosing adverse perinatal consequences. However, there is still no clear opinion about the feasibility of using Doppler as a screening test, as well as about the optimal pregnancy period for this type of study. The objective: is to study the hemodynamic features in pregnant women after assisted reproductive technologies (ART) application in the dynamics of the first part of pregnancy. Materials and methods. 299 pregnant women were examined – the main group included 249 women whose pregnancy occurred as a result of ART application. The control group consisted of 50 pregnant women with spontaneous pregnancy and its physiological course. I group – 94 women with tubal-peritoneal factor of infertility, II group – 87 women with endocrine factor of infertility, III group - 68 women whose infertility was caused by the male factor. Doppler ultrasound examination of the uterine arteries, arteries of the umbilical cord and middle cerebral arteries of the fetus were conducted. Results. It was found that the highest intensity of hemodynamics in the uterine artery basin at 11–12 weeks of gestation was recorded in a group of patients with a physiological course of pregnancy. The systolic-diastolic ratio in the right and left uterine arteries in these patients was 1.9 (1.8–2.7) and 2.1 (1.9–2.6), respectively. In contrast to women in the control group, pregnant women after ART application analyzed indicators were higher (1.6–1.9 times; p<0.0001). The systolic-diastolic ratio in the right uterine artery in III group was 3.0 (2.4–3.5), I group – 3.3 (3.1–3.4). Similar data were obtained analyzing the curves of blood flow rates in the left uterine artery – 2.9 (2.1–3.5) and 3.0 (2.7–3.6), respectively. The highest peripheral resistance, both in the right (3.6 (3.4–3.7) and left (3.5 (3.2–3.8) uterine arteries, was naturally registered in pregnant women of II group. In 36 (72%) patients with uncomplicated course and successful gestation at 11–12 weeks of pregnancy, blood flow was not recorded in the intervellon space. In the vast majority – 50 (73.5%) pregnant women of I group, two types of blood flow were registered in the intervellar space: pulsating arterial and continuous venous. Only in 18 (26.5%) patients of this group the blood flow in intervellon space was not determined. As a result of the obtained data analysis, it was found that at 16-17 weeks of gestation, the highest intensity of blood flow in the uterine artery pool was recorded in the control group. Thus, the systolic-diastolic ratio of the right and left uterine arteries in these subjects was 1.6 (1.5–1.8) and 1.8 (1.6–2.0). In pregnant women of the main group, the indicators were significantly higher (1.2-2.0 times; p<0.0001). The systolic-diastolic ratio in the uterine arteries in group III was 2,1 (1,9–2,6); 2,2 (1,9–2,5), in the II group – 3,1 (2,5–3,3); 2,2 (1,9–2,5), in the I group – 2,6 (2,5–3,2); 2,7 (2,5–2,9). In contrast to the control group, in which the systolic-diastolic ratio in the fetal umbilical artery was 3.4 (3.3–3.5), in III group patients, there was a significantly higher intensity of umbilical blood flow (S/D – 3.3 (3.5–3.6), p=0.03). At the same time, feto-placental hemodynamics in II and I groups patients was characterized by a significant increase in the numerical values of blood flow in the umbilical arteries (S/D – 4.5 (4.4–4.7), p=0.0001 and 3.5 (3.5–3.6), p=0.03, respectively). In patients of the control group, the systolic-diastolic ratio of the middle cerebral artery of the fetus at 16–17 weeks of gestation was 3.4 (3.4–3.5), almost completely coinciding with the same indicator in the umbilical artery (S/D – 3.4 (3.3–3.5). Patients of group III had a higher blood flow intensity, as evidenced by significantly lower (S/D 3.2 (3.1–3.3), compared with the control group (S/D 3.4 (3.4–3.5) absolute values of the systolic-diastolic ratio. An increase in the intensity of blood flow in the fetal medial artery (against the background of increased vascular resistance in the umbilical artery) was also recorded in the group of subjects of group II (S/D – 2.8 (2.7–2.9). High absolute values of systolic-diastolic ratio in the indicated vessel (4.4 (4.3–4.5) were found in the fetuses of the examined group and group, which characterize a significant decrease in the intensity of cerebral blood flow, compared with all the analyzed groups. Conclusions. Thus, the results of the study allow us to attribute Doppler ultrasound to highly informative research methods that make it possible to predict hemodynamic changes in the mother-placenta-fetus system, depending on the type of infertility, take preventive measures and start correction in time.

The objective: frequency decrease perinatal pathologies at women after ART on the basis of studying clinical-ehografical, endocrinological, biochemical, dopplerometrical, cardiotokografical and morphological researches, and also improvement of algorithm of diagnostic and treatment-and-prophylactic actions. Patients and methods. The work basis is made spent by us from 2012 on 2015 by complex inspection of 300 pregnant women from which 250 were after ART and 50 – firstlabours which pragnency without ART, and also their newborns. For the decision of an object in view of research spent to two stages. At 1 stage spent prosperctive research which included 150 pregnant women: з them 100 women pregnancy at which has come out ART (1 group) and 50 healthy women (control group). At 2 stage spent prospective randomization in which result of patients after ART have divided on two equal groups by therapy principle: 2 basic group - 75 pregnant women after ART at which used the algorithm improved by us; 3 group of comparison - 75 pregnant women after ART which have been spent on the standard treatment-and-prophylactic actions. Results. The results suggest that women after using ART is a high frequency of reproductive losses in the first trimester (10.0%), 3.0% of spontaneous abortion from 16 to 22 weeks, and 3.0% "early" premature delivery (22 to 28 weeks of pregnancy). The frequency of violations of the functional state of placenta in women after using IVF is 63.0%, which is the main cause of high levels of perinatal losses (40.0 ‰), and delivery by cesarean section (96.0%). Placental dysfunction in women after using ART characterized by retrohorialnyh hematoma (21.0%); size mismatch fruit (30.0%) and hypertonicity of the uterus (73.0%) against changes in fruit-placental blood flow - increased resistance index in umbilical artery and increased vascular resistance in the uterine arteries. Endocrinological and biochemical changes in placental dysfunction in women after using IVF starting from 28 weeks of pregnancy and are in significant reduction in progesterone, placental b1-microglobulin, B2-microglobulin of fertility and trophic в-glycoprotein. Conclusion. The received results: use of the algorithm of diagnostic and treatment-and-prophylactic actions improved by us allows to lower frequency of spontaneous interruption of pregnancy till 22 weeks – from 13.0% to 5.7%; «early» premature birth – from 3.0% to 1.0%; placentary dysfunction from 63.0% to 40.6%; cesarean sections – from 96.0% to 56.5%, and also perinatal losses – from 40.0‰ to 16.2‰.

Study objective: to determine the role and effectiveness of the proposed therapeutic and preventive complex and psychoemotional correction of hormonal disorders in the pregnancy dynamics after assisted reproductive technologies (ART) to improve the antenatal observation and prevention of obstetric and perinatal complications.Materials and methods. The study included 299 pregnant women: the main group included 249 women whose pregnancy occurred as an ART result; the control group included 50 pregnant women with spontaneous pregnancy. Therapeutic and prophylactic complex for pregnant women after ART included: micronized progesterone, magnesium oxide, folic acid, L-arginine aspartate, ω3-polyunsaturated fatty acids and long-term psychological correction on the eve of the ART program, at 8–10, 16–18 and 28–30 weeks of pregnancy. Results. There was a significant increase in the β-chorionic gonadotropin (β-hCG) level in women of the study groups in the first trimester of pregnancy against the background of the proposed treatment. Mean β-HCG value at 7–8 weeks of gestation in the subgroup IA exceeded the subgroup IB by 37% (p <0.05), in subgroup IIA it exceeded the subgroup IIB by 33% (p <0.05). The mean β-hCG value in subgroups IIIA and IIIB did not have a significant difference in the dynamics of the first trimester compared with the control group and among themselves (p >0.05).Mean progesterone value at 7–8 weeks of gestation in subgroup IA increased by 38% in comparison with pregnant women who received the conventional treatment complex (p <0.05), in subgroup IIA it was 73% higher than in subgroup IIB (p <0.05). There was no significant difference in the progesterone level in subgroups IIIA and IIIB in the dynamics of the first trimester.The average cortisol value at 23–24 weeks of pregnancy in subgroup IA decreased by 42% (p <0.05), in pregnant women with endocrine infertility against the background of the proposed treatment complex it was 62% less than in subgroup IIB (p <0.05). The average cortisol level in women with a male factor of infertility was 63% lower than in subgroup IIIB against the background of the proposed complex (p <0.05).Conclusion. Advanced therapy with micronized progesterone in combination with magnesium saturation, L-arginine aspartate, folic acid, ω-3 polyunsaturated fatty acids, as well as long-term psychoemotional correction is appropriate and effective compared to conventional therapy for pregnant women.

Objective. To assess the condition of newborns from women of the late reproductive period (LRP), depending on the parity of births.Material and methods. The authors examined 130 pregnant women and their 130 newborns. Group I consisted of 60 primiparous women of late reproductive period and their 60 newborns, Group II included 40 multiparous women of the late reproductive period and their 40 newborns, Group III (control group) consisted of 30 healthy pregnant women aged from 18 to 25 years and their 30 newborns. The authors performed a retrospective analysis of the gestation course and perinatal outcomes. Ultrasound and neurosonography were used among the instrumental research methods.Results. Women of the late reproductive period gave birth to children in a state of asphyxia twice more often, who develop neurological disorders 1,5 times more often and complex postnatal adaptation and disorders of the perinatal period are twice more likely. Among women of the late reproductive period, primiparous women gave birth to children with the most severe disorders.Conclusion. The high incidence of neurological diseases in children born from women of the late reproductive period is associated with age-related changes in their germ cells, the implementation of assisted reproductive technologies, and the intake of hormonal drugs in early pregnancy. The data obtained should be taken into account by obstetricians in the course of pregnancy in women of late reproductive age; they should be included in the group of high risk of developing neurological disorders in children.

                                  The issue of preserving the reproductive health of the nation in Ukraine is very acute. The psycho-emotional state of a woman is of particular importance for the prolongation of pregnancy and the normal course of labor. Violation of adaptive mechanisms which are aimed at restructuring the functional systems of the body during pregnancy and on the eve of childbirth, as well as the state of chronic stress contribute to the increase in the of obstetric and perinatal complications frequency and have an adverse effect on the course of pregnancy. The aim of the reaserch was to study the dynamics of psycho-emotional state features in pregnant women after assisted reproductive technologies (ART) application in order to improve the tactics of antenatal surveillance. To achieve this goal, 299 pregnant women were comprehensively examined in the dynamics of prospective observation, which were distributed as follows – the main group included 249 women whose pregnancy occurred as a result of the ART application. The control group consisted of 50 pregnant women with spontaneous pregnancy and its physiological course, which were registered for pregnancy at 6-8 weeks. The women of main group whose pregnancy occurred as a result of ART application were divided into three groups, depending on the factor that caused infertility. The first group included 94 women with tubal-peritoneal factor of infertility, the second group was formed by 87 women with endocrine factor of infertility, the third group included 68 women whose infertility was caused by the male factor. Pregnant women of the study groups by age, marital and social status, place of residence were representative, which allowed further to judge the differences caused by etiological factors of infertility. In order to determine the psycho-emotional state of pregnant women in the study groups in the screening mode, a clinical interview was conducted by filling out questionnaires that contained the constituent questions of the STAI tests in the modification of Yu. L. Khanin and the "Pregnant Attitude Test" by the method of I. V. Dobryakov. The obtained test results indicate that the average score of reactive anxiety in pregnant women of the main group exceeded the same indicator of the control group and was: 49 - pregnant women with tubal-peritoneal type of infertility, 56 - pregnant women with endocrine type of infertility, 44 - pregnant women with male factor of infertility, 24 - control group. According to the results of testing, a significant difference was revealed in the indicators of personal anxiety. The values of indicators of personal anxiety were: 51 - pregnant women with tubal-peritoneal type of infertility, 54 - pregnant women with endocrine type of infertility, 31  -pregnant women with male factor of infertility, 31 - control group. Low level of personal anxiety was observed in 26 (27,6%) pregnant women of I group, 29 (33,3%) pregnant women of II group, which is significantly less in comparison with the indicator of pregnant women of the control group – 33 (66,0%) and III group - 33 (48,5%) (p < 0,05). Moderate type of personal anxiety was observed in 46 (48.9%) pregnant women of group and 40 (45.9%) pregnant women of II group compared to the indicator of the control group – 11 (22, 0%) (p < 0,05). Moderate type of personal anxiety was determined in 25 (36,7%) cases in pregnant women of III group and did not differ significantly from the indicators of I, II and control groups (p > 0,05). A high level of personal anxiety was observed in 22 (23,5%) pregnant women of group I, 18 (20,8%) pregnant women of group II, which is significantly higher in comparison with the indicator of pregnant women of the control group – 6 (12,0%) (p < 0,05). Thus, the study of the psycho-emotional state of pregnant women after the application of ART deviations in the level of personal and reactive anxiety and pathological types of gestational dominant, which are inherent in pregnant women of the main group. Taking into account the above, we consider it appropriate to involve a psychologist to work with the examined pregnant women in order to correct the identified abnormalities.

To determine the role and effectiveness of the proposed the­rapeutic and preventive complex in the correction of psychoemotional state in the dynamics of pregnancy in pregnant women after assisted reproductive technologies (ART) application in order to improve the tactics of antenatal obser­vation and prevention of obstetric and perinatal complications. 299 pregnant women were comprehensively examined and a set of therapeutic and preventive measures was carried out: the main group included 249 women whose pregnancy occurred as a result of ART application. The control group consisted of 50 pregnant women with spon­taneous pregnancy. The complex of measures for pregnant women after ART application included: micronized pro­gesterone, magnesium oxide, folic acid, L-arginine aspartate, Omega-3 polyunsaturated fatty acids and long-term psychological correction – before ART program, at 8-10 weeks of pregnancy, at 16-18 weeks of pregnancy and at 28-30 weeks of pregnancy. Introduction of the proposed complex of psychoemotional correction contributed to the formation of reactive anxiety and personal anxiety levels at a moderate level in women of subgroups IA-44 (89.8%) and 43 (87.6%), IIA – 43 (89.6%) and 44 (91.7%) and IIIA – 30 (83.3%) and 26 (72.2%), which is considered to be an adaptive, physiological type during pregnancy. The positive effect of the proposed complex of psychoemotional correction demonstrates the improvement of processes of formation of type of component gestational dominant, its return to the optimal type in women of subgroup IA – 41 (83.6%), IIA – 39 (81.3%) and IIIA – 26 (72.2%) that is close to the physiological course of pregnancy and contributes to the reduction of perinatal and obstetric complications among pregnant women of these subgroups.

Objective of the research: conduct a Doppler ultrasound (DUS) assessment of utero-placentalfetal blood flow and the condition of newborns in the early neonatal period from women of the late reproductive period (LRP), depending on the parity of delivery, using the example of women in the Chechen Republic. Material and methods: retrospective multicenter study. DUS assessment of the state of utero-placental-fetal blood flow and the state of newborns in the early neonatal period was performed in 95 pregnant women, including: group 1–35 primiparous of LRP and their 35 newborns, group 2 – 35 multi-pregnant (MP) of LRP and their 35 newborns. The 3 control group included 25 healthy pregnant women aged 18 to 25 years and their 25 newborns. DUS was performed on Aloka SD SSD 3500 device (Japan), and a transvaginal sensor was used if necessary. Newborns were assessed on the APGAR score at 1 and 5 minutes after birth. Of the instrumental methods for examining newborns, brain ultrasound examination (neurosonography) was used. Results: analyzing the DUS results of LRP pregnant, depending on the labor parity, it was found that in the 1st group there was an increase in resistance in both uterine arteries (61%), an increase in the resistance index and pulsation index, a decrease in diastolic blood flow, characteristic of arteries with high resistance. Hemodynamic parameters in the mid-brain artery (MBA) of the fetus remained normal in all pregnant women. LRP women often born children in a state of asphyxia, with neurological disorders, and these children often has more complex postnatal adaptation and concomitant pathology. Among LRP women, primiparous has significantly more severe disorders. Conclusion: the data of uteroplacental fetal blood flow of the 1st group correspond to blood flow disorders of the IA degree, which indirectly indicates a compensatory reaction of the vascular system of uteroplacental fetal blood flow, as well as the absence of a tendency to an increase in the severity of fetoplacental insufficiency. It is possible that high incidence of neurological disorders in children born to LRP women is associated with age-related changes in their germ cells, use of assisted reproductive technologies, intake of hormonal drugs at an early stage of pregnancy and environmental factors associated with iodine deficiency in the region which includes the North Caucasus.

The objective: determination of risk factors of early preterm labor in single-pregnant women after ART on the basis of clinical and anamnestic data. Materials and methods. We study of 130 single-pregnancy pregnancies among the contingent of women with restored fertility after the use of therapeutic ART programs, which ended with early preterm labor. Group I consisted of 50 pregnant women with premature rupture of the membranes for which the tactics of pregnancy with were born by natural way. The second group consisted of 30 pregnant women with premature rupture of the membranes, who carried out general medical and prophylactic measures in accordance with the clinical protocols in accordance with the orders of the Ministry of Health of Ukraine. The control group (GC) has formed 50 pregnant women with early preterm labor with unbroken integrity of the membranes. Results. The retrospective analysis of the methods of fertility restoration in women who were included in the study, carried out by us, indicates the probable relationship of risk of early preterm labor with the ICSI method. The obtained data testify that pregnancy 42.5% of women of the main group, who was chosen ICSI technique ended with early preterm labor. In the contingent of patients whose pregnancy came with IVF, the percentage early preterm labor was 37.5 (р<0.05). The obtained results of researches testify to increase of risks early preterm labor (22.1–29.7%) in patients with chronic inflammatory diseases of the urinary system, which had a latent course. Conclusions. Among the reliable factors of early preterm labor risk, it is necessary to note the high frequency of intrauterine manipulations of diagnostic and therapeutic nature in the use of ART, which results in receptor dysfunction of the endometrium. Key words: risk factors of early preterm labor, assistive reproductive technologies, ICSI, IVF, premature rupture of the membranes, dysfunction of the endometrium.

The dynamic increase in the number of caesarean section in Ukraine and around the world remains one of the main topics of discussion, which is intensively discussing by leading scientists. The traditional assessment of the ability of the uterus scar during pregnancy, based mainly on the analysis of clinical and anamnestic data, is not high informative, and the ambiguous conclusions of the sonographic study indicate the need for further detailed study. Therefore, there is reason to believe that the development of criteria for ultrasound assessment of the condition of the uterus scar after previous cesarean section will use them to predict the possibility of spontaneous delivery in the future and remains relevant. The objective: study the features of ultrasound diagnosis of the condition of the scar on the uterus in pregnant and non-pregnant women. Materials and methods. Observations and retrospective analysis of medical records of pregnant women and birth histories in 150 women with a scar on the uterus after a previous cesarean section for the period from 2014–2019. Results. In women who became pregnant up to a year after the previous cesarean section, the most pronounced changes in blood flow were in the uterine arteries, especially during gestation 28–34 weeks. Also, in women with a failed uterus scar, changes in blood flow were most often observed in the uterine arteries at all levels and were significantly higher, compared with women with a capable uterus scar and women from the control group. In women with an insolvent uterus scar, the most pronounced changes in the indices of vascular resistance was observed in the uterine arteries, in particular the right uterine artery. Conclusion. The peculiarities of blood flow and vascular resistance in different vessels of the myometrium depending on the gestation period and the timing of pregnancy after a previous cesarean section. The obtained detailed ultrasound examination and mathematical calculation of the results of ultrasound examination of the uterus and postoperative uterus scar after previous cesarean section in non-pregnant women allowed to create a scale for assessing the condition of the uterus scar after previous cesarean section in non-pregnant women. Keywords: cesarean section, uterus scar, ultrasound, pre-pregnancy preparation of women.

Introduction. Intrauterine growth restriction (IUGR) is a leading cause of perinatal morbidity and mortality due to placental insufficiency. Currently, one of the new approaches to treating this disease is the injection of nutrients to the fetus through intravascular port-systems (catheters).Objective. To assess the impact of nutrient injections as treatment to fetuses with severe growth retardation.Materials and methods. Pregnant women with IUGR (abdominal circumference (AC) < 5th percentile) with the absence of diastolic flow in the umbilical artery and a fetal gestational age of less than 30 weeks were randomly divided into two groups. The treatment group included six pregnant women who had an intravascular port-system for the infusion of nutrients (amino acids and glucose) in the umbilical vein of the fetus for 14 ± 3 days. The control group consisted of eight patients who received only traditional dynamic monitoring and delivery at the optimum time of pregnancy. Fetal status was assessed using ultrasound equipment Accuvix V20 (Medison, South Korea) by examining indicators of biometry and Doppler study of blood flow in utero, umbilical arteries, middle cerebral artery, and ductus venosus with fetal vascular resistance index calculation - pulsatility index (PI). Criteria for blood flow disturbances in the vessels were considered PI values above normal values for their gestational age, which were defined as absence or reverse blood flow in a diastole in the umbilical artery.Results. In a comparative analysis of the two groups, the treatment led to a 44.7% increase in AC of the fetus (121.0 ± 11.5 mm and 219.3 ± 18.3 mm, respectively, p ˂ 0.001). In all cases, the profile of blood flow in the umbilical artery had a positive diastolic component. As a result, there was a 45.3% decrease in PI in the umbilical artery (2.14 ± 0.54 and 1.17 ± 0.15, respectively, p < 0.05). Average fetal weight in the study group was not significantly higher than the control group (1,120.3 ± 213.6 g and 909.6 ± 131.4 g, p > 0.05).Conclusion. Thus, injection of nutrients to the fetuses through intravascular port-system improved placental perfusion and metabolism, which has the potential for improved fetal growth. This, in turn, promoted full-term pregnancy and improved perinatal outcomes in fetal pathology.
