METHOD OF DIAGNOSTICS OF PHYSIOLOGICAL COURSE OF PREGNANCY AND CHRONIC FETOPLACENTAL DEFICIENCY Russian patent published in 2008 - IPC A61B5/432 

FIELD: medicine; obstetrics.

SUBSTANCE: fetal cardiac rhythm is registered. Additionally cardiointervalography is performed with determination of spectral power density of maternal and fetal cardiac rhythm waves and selection of very low frequency VLF, low frequency LF and high frequency HF levels, regulator system tension index TI, cortizol and adrenaline level in maternal and fetal blood. Physiological pregnancy course is defined at adrenaline level of 28 ng/mol, cortizol level of 360 ng/ml, indices of VLF=120 relative units, LF=40 r.u., HF=20 r.u., TI=70 r.u., for the mother and at indices of VLF=25 r.u., LF=2 r.u., HF=1 r.u., TI=250 r.u. for the fetus; compensated form of chronic fetoplacental deficiency is detected at the adrenaline level of 46 ng/ml, cortizol level of 695 ng/ml, VLF=180 r.u., LF=50 r.u., HF=100 r.u., TI=160 r.u. for the mother and at VLF=45 r.u., LF=5 r.u., HF=1 r.u., TI=400 r.u. for the fetus; and decompensated form of chronic fetoplacental deficiency is detected at the adrenaline level of 2 ng/ml, cortizol level of 1003 ng/ml, VLF=900 r.u., LF=25 r.u., HF=10 r.u., TI=30 r.u. for the mother and at VLF=3 r.u., LF=1 r.u., HF=0 r.u., TI=700 r.u. for the fetus.

EFFECT: improved accuracy and information capacity of diagnostics of physiological pregnancy course and chronic fetoplacental deficiency forms.
