METHOD OF PRENATAL ULTRASONIC DIAGNOSTICS OF FETUS TOBACCO SYNDROME IN ULTRASONIC SCREENING OF PREGNANT WOMEN IN 30-34 WEEKS OF GESTATION Russian patent published in 2020 - IPC A61B8/00 A61B5/107 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to prenatal ultrasonic diagnostics, and can be used for prenatal diagnosis of foetal tobacco syndrome during U3-screening in period of 30–34 weeks of gestation. Determining and comparing the obtained values with E.Merz biometric tables (2011) in compliance with the gestational period of the fetometric parameters: biparietal head size: 74 mm - 30 weeks, 77 mm - 31 weeks, 79 mm - 32 weeks, 81 mm - 33 weeks, 83 mm - 34 weeks, head circumference: 277 mm - 30 weeks, 285 mm - 31 weeks, 293 mm - 32 weeks, 300 mm - 33 weeks, 307 mm - 34 weeks, length of femurs: 53 mm - 30 weeks, 55 mm - 31 weeks, 57 mm - 32 weeks, 59 mm - 33 weeks, 61 mm - 34 weeks, shin bone length: 46 mm - 30 weeks, 48 mm - 31 weeks, 50 mm - 32 weeks, 51 mm - 33 weeks, 53 mm - 34 weeks, shoulder bone length: 45 mm - 30 weeks, 46 mm - 31 weeks, 48 mm - 32 weeks, 49 mm - 33 weeks, 51 mm - 34 weeks; morphological indices: cerebellar cross diameter: 31 mm - 30 weeks, 32 mm - 31 weeks, 34 mm - 32 weeks, 35 mm - 33 weeks, 36 mm - 34 weeks, orbit width: 13.3 mm - 30 weeks, 13.7 mm - 31 weeks, 14 mm - 32 weeks, 14.3 mm - 33 weeks, 14.6 mm - 34 weeks, distance between orbits: 15.2 mm - 30 weeks, 15.6 mm - 31 weeks, 16.1 mm - 32 weeks, 16.5 mm - 33 weeks, 17.00 mm - 34 weeks; determining umbilical cord diameter: 13.95 mm - 30 weeks, 14.11 mm - 31 weeks, 14.27 mm - 32 weeks, 14.85 mm - 33 weeks, 15.44 mm - 34 weeks. If observing two and more fetometric values below 5^th percentile in combination with one or more morphological indicators below 5^th percentile, diagnosing the presence of tobacco foetus syndrome, without consideration of the degree of tobacco dependence and duration of smoking during pregnancy and without indicating a low estimated weight of the foetus.

EFFECT: method enables diagnosing foetal tobacco syndrome prenatally by creating an algorithm for ultrasonic diagnosis of foetal tobacco syndrome in a third ultrasound screening of pregnant as a result of ultrasonic signs of foetus damage in tobacco dependence of a pregnant woman with various duration and intensity of smoking during pregnancy.
