Clinical and statistical analysis of the course of preterm birth based on the materials of communal enterprise «Regional Perinatal Center of the Rivne Regional Council» in 2013–2023 years

Abstract

One of the priority tasks of modern medical science and practice is the preservation of reproductive health and the gene pool of the nation. It is especially difficult to perform this task during the russian war in Ukraine, which has been going on for more than ten years. According to sociologists, the outcomes of a low birth rate for the country will be catastrophic precisely because of the war.One of the reasons for the decline in the quality of health in the future is the increase in the specific weight of premature births, the frequency of which, according to the World Health Organization, has increased in Ukraine already after six months of full-scale war.The objective: to conduct an analysis of the course of premature births in the conditions of war based on the materials of the communal enterprise (CE) “Regional Perinatal Center of the Rivne Regional Council” for 2013–2023.Materials and methods. A retrospective clinical and statistical analysis of 2,742 histories of pregnancy and childbirth of women who were in labor between 22/0–36/6 weeks of gestation in obstetric departments of the communal enterprise “Regional Perinatal Center of the Rivne Regional Council” in 2013–2023 was carried out.Results. According to CE “Regional Perinatal Center of the Rivne Regional Council”, a progressive decrease in the total number of births by 41.9% was observed in the Rivne Region from 2013 to 2023. At the same time, in the general population of women giving birth, the specific rate of premature births did not have a tendency to increase.In the structure of preterm births, early and late preterm births prevailed. The specific gravity of very early preterm births, which are the most unfavorable for perinatal outcomes, did not have a sustained upward trend. At the same time, the frequency of too early premature births among residents of districts and territorial communities of the Rivne region has significantly increased (2013 – 19 (79.2%) cases, 2023 – 17 (100.0%) cases; p<0.05).Every second premature birth occurred within the first day of hospitalization of a pregnant woman, while the specific rate of such too early premature births increased by 3.4 times during the analyzed period, which significantly worsens the chances of survival of newborns and is the reason for their high perinatal morbidity.The number of premature births in pregnant women with multiple pregnancies remains stable. Every third preterm birth took place on the background of early premature rupture of the fetal membranes, while a significant increase in the frequency of this complication was found in women who gave birth at 22/0–27/6 weeks of pregnancy.Traditionally, the specific rate (55.7–57.5%) of surgical delivery by caesarean section of pregnant women and mothers with premature births remains high, which contributed to a reliable reduction of the perinatal mortality rate of premature babies by 13.7% due to the reduction of antenatal losses. Indicators of early neonatal death were formed at the expense of newborns from too early and early premature births in the same ratio.Conclusions. According to thedata of CE “Regional Perinatal Center of the Rivne Regional Council”, there was a progressive decrease in the birth rate in the Rivne Region with a simultaneous stabilization of the number of premature births. The widespread use of a holistic approach during the medical care of pregnant women and the introduction of modern methods of care for premature newborns ensured a significant decrease in the rate of perinatal death of premature infants due to the reduction of antenatal losses.
