[Functional morphology of the neonatal umbilical cord during cesarean section].
The morphology of the neonatal umbilical cord was studied in 23 women during elective surgical delivery and in 32 women during normal physiological delivery. Organ- and histometric indices were used. These included: length, weight, a linear weight unit; the average diameter of the umbilical cord, etc. The significant increase of organometric indices (a linear weight unit of weight, the average diameter of the umbilical cord) and histometric ones (a drastic venous lumen increase, a significant increase in the proportion of Wharton's jelly) document acute umbilical blood flow disorder in the absence of the conditions characteristic for normal delivery. Moderately pronounced edema of the umbilical cord peripheral layer emerges. A complex of morphofunctional umbilical cord changes during surgical delivery serves as predictor of neonatal respiratory distress syndrome.
