title: [Simultaneous study of the placental, myometrial and cervical circulations (indium 113 and anemometric thermometry). 3). Double blind study of the action of intravenous ritodrine during normal pregnancy].
abstract: The authors measure the changes in placental and myometrial blood flow using an isotope technique with Indium 113. They calculate an index of the variation in placental blood flow (I.V. D.P.) and an index of variation of myomoetfrial blood flow (I.V.D.M.) after injecting Ritodrine or a placebo between the 28th and the 36th week of pregnancy. This study was carried out in 26 normal women. At the same time using Brotanek's technique changes in the cervical blood flow were registered. No change in the placental, myometrial or cervical blood flows were noted while Ritodrine was being transfused intravenously.
