Summary:

Research objective. The objective of this research is the study of venous blood flow parameters of lower uterus segment and cervix of uterus at the physiological course of preliminary period. Material and methods. The study was based on the investigation of the course of preliminary period of 90 patients with physiological delivery at term. Results. There is a growing rate of venous blood flow of lower uterus segment and cervix of uterus at rest as well as at peak of contractions. Conclusion. Veins are transformed into structures similar to lacunae at the physiological course of preliminary period. There is a growing rate of venous blood flow of lower uterus segment and cervix of uterus which results in blood storage and seems to be one of the mechanisms leading to cervical dilatation.
