Filter by:Recent studies show that EET and 20-HETE have important biological effects, particularly in the vascular system. The investigators studied the effect of eicosanoids on the gravid rat uterus. The results suggest that 20-HETE had an tocolytics effect on gravid uterus. In the previous study, we demonstrated that the enzymes of the pathway of EET were present in human uterine tissues. Moreover, the addition of an inhibitor of degradation of EET had an tocolytic effect on the human myometrium, as the exogenous addition of 8.9, 14,15-EET and 20-HETE. Objectives: Primary objective: To compare the balance of different metabolic pathways of arachidonic acid (AA) of the pregnant human myometrium in pathological situations (preterm labor, uterine atony, prolonged pregnancy). Specific objectives: i) To study the effect of derived from the AA on in vitro contractile activity of normal and pathological uterine tissues, and ii) detect and quantify the different sub-products of metabolism of AA in the uterine tissues (myometrium, fetal membranes and placenta). The management of uterine contraction is in the heart of modern obstetrics year, yet the progress made in other specialties, based on the study of smooth muscle have not yet been transposed in obstetrics. A better understanding of systems for regulating the contraction is important in terms of 1) new physiological knowledge, but it could also be the source of 2) modification of strategies to take care of premature delivery (new Tocolytic), or 3) improving the efficiency of uterine muscle during delivery or 4) for treatment of patients with prolonged pregnancy.
The purpose of this trial is to determine whether cervical ripening with isosorbide mononitrate reduce caesarean section in women with post term pregnancies.
Post term pregnancy is a risk pregnancy. Aim of the study was to investigate whether induction of labor at gestational age 289(41 weeks+2 days) reduces neonatal morbidity compared to expectant management. Secondary aims was to assess the effect on mode of delivery and maternal complications, as well as assess women's views and experiences. Our 0-hypothesis was that induction of labor at gestational age 41+2 did not result in better outcome of pregnancy, measured as perinatal morbidity. Following inclusion, women were randomly allocated to induction of labor or to monitoring of pregnancy every third day until delivery
The purpose of the study is to determine whether castor oil is effective in inducing labor.
It is debatable whether routine ultrasound scanning of pregnancies at about 20 weeks of pregnancy has substantive benefits for mothers and babies. Few studies have addressed this issue in poorly resourced settings. This trial will attempt to determine the benefits, if any, of a policy of routine ultrasound scanning of normal pregnancies versus a policy of no routine (only selective) scanning. This will be done by recruiting about 900 women in South Africa, and randomly allocating about half to routine scanning and half to selective scanning groups, and following up their pregnancies.
