[The characteristics of the fetal-maternal-placental blood flow in habitual abortion]. / Osobennosti plodovo-matochno-platsentarnogo krovotoka pri privychnom nevynashivanii beremennosti.

Dopplerometry of uterofetoplacental blood flow in 59 women at pregnancy terms of 24 to 40 weeks with a history of habitual abortions revealed disordered blood flow in approximately 60% of cases. Pathologic shifts first develop in a fetus as a rule. Moderate disorders of the uterofetoplacental blood flow in women with a history of habitual abortions do not result in the majority of cases in chronic disorders of fetal status, whereas marked disorders of blood flow often lead to fetal intrauterine suffering.

[Diagnostic value of Doppler ultrasonography in the evaluation of the status of uterine blood flow in puerperium]. / Diagnosticheskoe znachenie dopplerometrii v otsenke sostoianiia matochnogo krovotoka v poslerodovom periode.

A study of 118 puerperants+ revealed that Doppler metry objectively evaluated the artery blood flow in the postpartum uterus. There was a progressive increase in uterine vascular resistance in the uncomplicated postpartum period following spontaneous labour, whereas there was a reduction in peripheral resistance in the endometritis-complicated period, which caused a rise in the end-diastolic blood flow. Postpartum uterine blood flow following cesarean section displayed low peripheral resistance in the presence or absence of an inflammatory process.

Examination of 80 women in their third trimester with chronic fetal abnormalities has shown that movement of the amniotic fluid in the fetal trachea can be detected during fetal respirations. The pattern of amniotic fluid velocity is significantly affected by chronic fetal stress. Evaluation of pneumodopplerographic findings enables identification of 90% of satisfactory and 80% of poor fetal conditions.

[Changes in cardiotocographic indicators in fetal hypotrophy]. / Izmenenie kardiotokograficheskikh pokazatelei pri gipotrofii ploda.

The investigation of 220 females with the third trimester of pregnancy revealed that ++cardiotocographic values naturally varied with developing fetal hypotrophy. For instance, hypotrophy, stage I, corresponded, as a rule, to the initial manifestations of fetal chronic disorders whereas hypotrophy, stages II and III, corresponded to the moderate and, occasionally, severe health status.

A total of 351 females with physiological pregnancies repeatedly (1928 examinations) underwent ultrasonic fetometry. The investigations revealed clear-cut correlations between the term of gestation and biometric parameters such as the mean diameter of the fetal head, abdomen, heart as well as the length of its foot, femur and humerus. The average mistake in the identification of pregnancy terms which was performed on the basis of simultaneous analysis of the parameters considered was 5.73 days in all terms of gestation.
