[Diagnosis and therapy of hemodynamic disorders. A contribution to the management of pregnancies with threatened premature labor].
114 pregnant women (without multiple pregnancies) with premature labour were examined in a randomized prospective study. Pulsatility index (PI) in the uterine artery and fetal thoracic aorta was the parameter we used for the examination, the determination of which was done with doppler sonography at the time of hospital admission. Therapy with beta-sympathomimetics alone or additionally either Oxygen inhalation therapy or transcutaneous dorsal nerve stimulation were conducted and the pulsatility index was controlled at intervals of one and two weeks after initiation of the aforementioned therapy. The negative correlations which we determined between pulsatility index and prolongation of duration of pregnancy, gestational age at the time of delivery and birth weight were significant. This confirms the clinical importance of maternal perfusion already at the time of admission for the clinical end-results. Similarly significantly negative correlations between pulsatility index of uterine vessels, weight percentile of the corresponding newborns and antenatal CTG scores (Fischer) verify the close connections between the hemodynamic, nutritional and respiratory partial functions of the fetoplacento-maternal unit. The clinical results after normalization of an impaired perfusion were found to be improved significantly after a combined therapy with beta-sympathomimetics and transcutaneous dorsal nerve stimulation (TNS) as compared with beta-sympathomimetic therapy alone. These results justify the recommendation that doppler sonographic measurements of utero-placental perfusion can be used for the diagnostic and therapeutic concept in pregnancies with premature labour.
