METHOD FOR ASSESSING FOETUS RESISTANCE TO OBSTETRIC HYPOXIA Russian patent published in 2014 - IPC A61B8/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to obstetrics and gynaecology, and can be used in delivery. That is ensured by localising predominantly a placenta in the uterus and a place of umbilical cord attachment with an ultrasound detector in a projection of the above place on a woman's stomach. A foetus image is visualised simultaneously with the uterus and placenta under the detector in a cross section with a front or side the predominant localisation of the placenta in the uterus. The detector is fixed, and dynamics of foetus's physical activity, uterine wall thickness, ultrasonic echogenicity of the uterus, placenta, thickness of their blood vessels and pulsation amplitude are controlled continuously. If observing constant thickness and ultrasonic echogenicity of the uterus and placenta, thickness and pulsation amplitude of their vessels and continuous weak contraction and relaxation of the muscular groups of all foetus's body parts that are represented by image vibrations on the screen, the foetus's condition is considered to be good with no labours. If observing regular reductions of the thickness of uterine walls, vessel and pulsation amplitude, ultrasonic echogenicity of the uterus and placenta coinciding with the periods of a foetus's rest in a position with legs and arms pressed tightly to the body and with hands clenched, an excellent foetus resistance to hypoxia in labour is stated. If the foetus shows respiratory rib movements, multiple flexion-extension movement of the limbs and opening hands before the period of reduction of uterine wall thickness, ultrasonic echogenicity of the uterus and placenta, thickness and pulsation amplitude of the blood vessels is completed, the length of the rest period is started with the above period. If the length tends to zero testifies to bad foetus resistance to hypoxia in labour.

EFFECT: method provides the well-timed preparation of the pregnant woman fort the delivery by improving accuracy and safety of detecting uterine and placental ischemia periods and assessing the foetus's state under the conditions preventing the uncontrolled intensification of the hypoxic foetus involvement.
