Prolonged newborns and prolong pregnancy

The article is devoted to the current problems of obstetrics, perinatology and neonatology. The article presents a literary review and covers scientific views on the factors of births and hazardous factors that lead to transfer and prolonged pregnancy. The most common perinatal complications of a delayed pregnancy are stillbirth, asphyxia, and birth trauma. Neonatal morbidity in premature infants is 29% and perinatal mortality is 19%, which is higher than in preterm infants. If the pregnancy is 43 weeks or more, these rates will increase. All of these diseases are associated with a decrease in the fetal resistance to hypoxia due to the large size of the brain and morphological changes in the placenta. Therefore, the incidence of meconium aspiration syndrome and fetal distress syndrome at birth increases, leading to high perinatal morbidity and mortality.
