The study revealed pathomorphological changes in the placenta in late preterm birth from 34 weeks to 36 weeks and 6 days. Late preterm birth is accompanied by morphostructural changes in the placental tissue, manifested by involutive-dystrophic changes, impaired maturation of chorionic villi as well as the presence of compensatory-adaptive reactions.

Attempts of vaginal delivery in cases with a scar on the uterus after a previous cesarean section are more successful after appropriate psycho-prophylactic preparation during pregnancy. The purpose of the study is to reduce the frequency of repeated cesarean section operations. A comparison was made of the methods of delivery for pregnant women with a scar on the uterus after comprehensive training on an improved program and unprepared pregnant women. A total of 158 women were included in the study. Among them were those who had a cesarean section in history, but not trained for the current childbirth, only 5% gave birth independently. At the same time, women trained under the improved program had independent deliveries in 45.6% of cases (OR 5.813; 95% CI 0.826-40.885). The results confirm the effectiveness of the proposed improvements in the preparation of pregnant women with a scar on the uterus. The intention of such women to give birth through the natural birth canal, formed as a result of preparation, is an important factor for successfully overcoming the difficulties of the delivery process.

The caesarean section is an important factor characterizing of obstetric care. In recent decades, the frequency of cesarean section has become pandemic. The large variability of the initial state of women in labor and the variety of indications for surgery do not allow us to identify the main determinants. In order to develop effective measures to reduce the frequency of abdominal delivery, WHO recommends using the M. Robson classification (TGCS). A study using the M. Robson scale identifies the patient population, among which a decrease in the number of abdominal delivery is possible and measures can be developed aimed at reducing the frequency of cesarean section in level II hospitals.
