[Effects of prenatal factors on the colloid-osmotic status of the newborn].

Studies of prenatal factor effects on the newborns' colloid-osmotic status, a pressing problem in present-day obstetrics, were carried out in 2 groups of women: Group 1 consisted of 50 women with spontaneous delivery and Group 2, also consisting of 50 women, who delivered via cesarean section, 25 of them because of a cicatrix on the uterus and the rest because of severe gestoses characterized by nephropathy and Stage III pre-eclampsia. Blood samples were collected directly after delivery from the mother's vein and from the newborn's umbilical vein, and the colloid-osmotic status of the plasma was analyzed. The results permitted singling out a number of prenatal factors influencing the newborns' colloid-osmotic status. These factors are as follows: obstetrical abnormalities, gestosis among other things; intensive care of the mother during delivery or after surgery, administration of diuretics, delivery mode, etc. These results have brought the authors to a conclusion that standardized infusion therapy without due consideration for the colloid-osmotic status is inadmissible, for it may result in iatrogenic complications in the newborns.
