METHOD FOR PREDICTING INITIAL DISORDERS OF UTERINE CIRCULATION IN THE SECOND HALF OF PREGNANCY Russian patent published in 2007 - IPC A61B5/488 

FIELD: medicine, obstetrics, perinatology.

SUBSTANCE: it is necessary to evaluate uterine circulation with rheohysterographic values during 2-3 cardiac cycles, moreover, current electrodes should be located at a costal arch and on a right thigh, and potential electrodes should be fixed at anterior abdominal wall in area of the bottom and inferior segment of uterine body. Then it is necessary to determine diastolic index, rheographic index and volumetric circulation in radial and spiral arteries, calculate the ratio of diastolic index against rheographic index (DI/RI) and the ratio of volumetric circulation of spiral arteries against radial arteries (SA/RA) and at DI/RI values being above 0.6 relative U and SA/RA ones being above 1.0 relative U one should diagnose initial disorders of uterine circulation that illustrate the decrease of circulatory intensity in the arteries of uterine-placental area and inhibited venous outflow from intervillous space. The innovation should be highly useful in the work of women's consultations, perinatal centers and in the Departments of Pathology in pregnant women for earlier diagnostics of affected uterine circulation in the second half of pregnancy.

EFFECT: higher accuracy and specificity of diagnostics.
