[Evolution of surgical delivery during the past 35 years according to the data of the All-Union Research Center for Maternal and Child Health of the Ministry of Public Health of the USSR].

A distinct evolution of surgical delivery has been demonstrated over the past 35 years. In the past decade, the proportion of surgical deliveries has grown considerably owing to the increasing rate of cesarean sections. In most cases, the operation is performed for combined indications and, quite frequently, for the sake of the fetus. Perinatal parameters have improved while there has been no clear-cut correlation between the increasing rate of cesarean section and declining perinatal mortality. Further development of rational labor management principles is necessary.

[Cortisol contents in maternal and umbilical artery blood during delivery of low birth weight fetuses].

Cortisol was measured in 50 parturients with low birthweight (LBW) fetuses in the course of vaginal delivery (n-18) and cesarean section (n-32). Twenty normal parturients whose pregnancy and labor were uncomplicated were taken as controls. In the main group, low birthweights corresponded to gestational age in 30 parturients, and fetal growth retardation (FGR) was diagnosed in 20. In the course of vaginal delivery, maternal cortisol level increased significantly, the rise being higher in parturients with the FGR syndrome. In both groups, blood cortisol levels were higher in the umbilical artery as compared to umbilical vein; in FGR cases, umbilical-artery cortisol level approached the respective values in control newborns. Following cesarean section, LBW fetuses showed considerably lower umbilical cortisol levels. Separate examination of cortisol fractions has demonstrated that free cortisol goes up in the maternal blood both at vaginal and abdominal delivery. The effect of corticosteroids, used to prevent respiratory distress syndrome, on maternal adrenal activity and LBW fetuses has been evaluated.
