| Summary: | Selection of the optimal tactics of pregnancy and childbirth significantly depends on the expected volume of amniotic fluid. The amount of amniotic fluid reflects a condition of a fetus and changes at pathological conditions of both a fetus, and an uteroplacental complex. The aim of the study was a modification of ultrasound’s methods for determining the expected volume of amniotic fluid. The error in determining volume of amniotic fluid by the Chamberlain’s and Phelan’s methods exceeds 10%. On the basis of 3D-modeling of the volume of amniotic fluid and fetal weight determined pattern change, which is expressed by the formula: V AF=200× IAF +0,08× М -1 500, where IAF - index of amniotic fluid (mm), M - fetal weight (g). The index of amniotic fluid is defined as the sum of the following pockets: K 1 - the perpendicular from the calvarium of the fetus to the prevailing wall of the uterus; K 2 - the perpendicular from the pelvis of the fetus to the prevailing wall of the uterus; K 3, K 4, K 5, K 6 - perpendiculars from the anterior, posterior and lateral surfaces of the abdomen fetus at the level of the stomach to the prevailing walls of the uterus. In calculating volume of amniotic fluid according to the proposed ultrasonic formula error does not exceed 5,3%. |
