Ultrasonic predictors of a condition of a fetus and newborn for the pregnant woman with insulin-dependent diabetes mellitus

Abstract

For 140 pregnant women were conducted an ultrasonic fetometry and research of a fetus hemodynamics. The following results were obtained in different firms of gestation we have found the changes of umbilical artery blood flow velocity in 92% of cases and in a fetal aorta - in 80% of cases and these values exceeded on 15-30% of the control values.

For 140 pregnant women were conducted an ultrasonic fetometry and research of a fetus hemodynamics. The following results were obtained in different firms of gestation we have found the changes of umbilical artery blood flow velocity in 92 °/o of cases and in a fetal aorta - in 80% of cases and these values exceeded on 15-30% of the control values. By most typical predictors (p=0,004) for birth of newborn in a mean gravity condition were: systolic-diastolic ratio in umbilical artery > 2,8, systolic-diastolic ratio in fetus aorta > 5,6. Glycemia level within 6 weeks before research was <8,0 mmol/L and the level of a glucosuria exceeded 22 g/day. Characteristic (p=0,0014) predictors for birth infants in heavy condition were: fetus BPD < 30 percentile level of a population and/or systolic-diastolic ratio in umbilical artery, systolic-diastolic ratio in fetus aorta > 5,6, thus the level of a glycemia exceeded 8,9 mmol/L. In group with decreasing of BPD < 20 percentile and DA < 30 percentile level and detection of a zero or negative diastolic component of blood velocity in fetus aorta we Have observed perinatal loss of a fetus or newborn, in 83% cases (p=0,006). Thus, ultrasonic dynamic control and compensation of hyperglycemia can help to improve perinatal results with early predicting of poor fetal outcome.
