METHOD OF DIAGNOSING DEGREE OF SEVERITY OF CHRONIC PLACENTAL INSUFFICIENCY

摘要

FIELD: medicine.;SUBSTANCE: invention relates to medicine, namely to obstetrics and gynecology, and is intended for diagnostics of degree of chronic placental insufficiency severity. Degree of lack of correspondence of ultrasonic fetometry (US fetometry) data to gestation age of fetus is determined. Assessment if carried out by diagnostic CPI scale. Degree of blood flow impairment in uterine and umbilical arteries, integral parameter of fetus state (IPFS) and response of cardiovascular system of fetus (RCVSF) are evaluated. Each said parameter is given definite points depending on value. Calculation of final parameter is performed by summing up points given to said parameters. If value of final parameter in accordance with elaborated classification of CPI severity degree is from 1 to 3 points, I degree of CPI severity - dysfunction of placenta, is diagnosed; from 4 to 9 points - II degree of CPI severity - decompensated placental insufficiency; from 10 to 13 points - III degree of CPI severity - progressing decompensated placental insufficiency; from 14 points and higher - IV degree of CPI severity - critical placental insufficiency.;EFFECT: method is safe and non-invasive, makes it possible to increase accuracy of diagnostics of CPI severity degree due to standardisation of diagnostics process by application of elaborated clinical classification of said pregnancy complication, based on complex point scale of estimation of CPI severity degree.;3 ex
