[Dynamics in the 3d stage of labor observed by ultrasound].

In two groups, with 50 pregnant women each, changes in the third stage of labour were followed up by a real-time scanner. In the experimental group the umbilical cord on the mother's side as not tied up, while in the control external uterine wall to the chorionic line in the separated placenta immediately before a cord traction intervention amounted to 5.45 cm, while in the control group, under the same conditions, it amounted to 8.61 cm and was caused by the intensified development of the retroplacental hematoma. The difference was statistically significant (P < 0.001). In the way presented, along with the shortening of the third stage of labour, the authors prevent the development of anemia in parturients.
