Past medical history, present pregnancy events, and demographic/environmental characteristics can help the practitioner select ...
Kopelman J N - - 1989
We compared oral ritodrine and terbutaline for the prevention of recurrent preterm labor. Women between 20 and 35 weeks' gestation who successfully completed a course of intravenous tocolysis were eligible for inclusion. One hundred two patients were randomized to oral ritodrine (20 mg every four hours) or oral terbutaline (5 ...
Bry K - - 1989
According to the current view, the fetal membranes and the amniotic fluid are central in transmission of signals resulting in labor and delivery. It has also become increasingly evident that although preterm and term labor share common pathways in activation of uterine contractions, the regulatory aspects are fundamentally different. The ...
Spätling L - - 1989
The treatment of premature labor with beta-adrenergic substances is complicated by side effects. Although most human control mechanisms are pulsatile, therapy is usually administered continuously. We designed a microprocessor-controlled pump to allow pulsatile tocolytic infusion, hoping to reduce the total dose and thus the side effects. In 33 patients pulsatile ...
