title: [Uterine-placental-fetal blood flow and fetal cardiac activity during the ginipral treatment of premature labor].
abstract: Effects of intravenous and oral hinipral on the uteroplacentofetal blood flow and fetal heart work were studied in tocolytic therapy of preterm labor in 27 pregnant women at terms 25-35 weeks. Intravenous infusions of hinipral resulted in a significant reduction of the systolic-diastolic ratio in the umbilical artery, with the blood flow in the uterine arteries persisting stable, and in a significant reduction of the fetal heart rate and increase of fetal heart rhythm variability, as evidenced by cardiotocogram. In oral tocolysis the reduction of the umbilical artery was related to the pregnancy term; fetal heart rate and heart rhythm variability were within the normal range over the course of the investigation. The results evidence no negative effects of the drug on the uteroplacentofetal blood flow and fetal cardiovascular system both in oral and parenteral forms of tocolysis.
