Active clinical trials for "Pregnancy, Prolonged"

This randomized clinical trial will examine if there are any differences between post-dates inductions (inductions after 40 weeks of pregnancy) begun in the morning compared to the evening for first-time mothers. Sleep and fatigue measures will be measured to see if they differ by time of induction. Other measures will include the rate of births within 24 hours of admission, length of labor, use of labor analgesics, and method of delivery.

Meconium constitutes the bowel contents of the fetus and is normally expelled only after birth. However, it may be secreted into the amniotic fluid of 20% of all fetuses. Meconium Stained Amniotic Fluid had been recognized from ancient times as an obstetric hazard which complicates delivery and is associated with increased newborn morbidity and mortality. At present there is no viable diagnostic test for Meconium prior to the onset of labor and the rupture of membranes. The system developed for the detection of Meconium, based on recognizing a characteristic fluoroscopic spectral pattern emitted by Meconium under light excitation at a specific wavelength. The diagnostic test being developed does not require penetration into the amniotic sac and is safe, painless and simple to perform.

To evaluate the value of measuring cervical length as a predictor of vaginal birth after induction of labor with prostaglandins in pregnancies with 41 weeks of gestation.

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.

Doppler measurements in the Middle Cerebral Artery (MCA) is a part of the assessment for assessing fetal well-being in complicated pregnancy, including Intra Uterine Growth Retardation and Fetal Anemia. The use of this Doppler measurement in uncomplicated term pregnancies is not a common practice due to lack of information. However, several studies use the MCA Pulsatility Index (PI) as part of the Cerebro-Placental-Ratio (CPR) measurment at term. The purpose of this trial is to assess MCA Doppler variability in term, uncomplicated pregnancy.

Pregnant Women beyond the date of birth. will be followed while coming to routine monitoring. physiological parameter of cervical length will be measured as the differential predictor to determine their due date. the cervical length will be measured as part of routine gynecologic examination to women who come for routine over due date follow up. additional medical data will be collected from the patient medical record.- demographic data, and all the routine prenatal medical care the women will receive up to the delivery.and delivery outcomes.
