Changes in Maternal-Fetal Blood Flow Velocity Wave Forms with Ritodrine Tocolysis in Preterm Labor.

Objective: To evaluate the effects of ritodrine on the maternal and fetal blood flow. Material and Methods: Eighty-six women in the 28-35 week of pregnancy were included in the study. Doppler wave forms were recorded from maternal uterine and fetal umblical and middle cerebral artery before and after the treatment with ritodrine. Results and Conclusion: Ritodrine infusion caused a decrease in S/D ratio of uterine and umblical artery Doppler. There was no effect on the middle cerebral artery. Key words: Preterm labor, Tocolysis, Doppler.
