Active clinical trials for "Obstetric Labor, Premature"

Placement of a vaginal pessary reduces significantly the rate of spontaneous preterm birth in pregnant women with short cervical length after an episode of threatened preterm labour.

The purpose of this study is to determine efficacy of vaginal and oral progesterone after tocolytic therapy in threatened preterm labor

The investigators study objective is to investigate the effectiveness of vaginal micronized progesterone in prolonging pregnancy after an episode of preterm labor which responded to tocolytic treatment. Furthermore, the investigators aim is to study the mechanisms of actions of progesterone supplementation by examining its effect on the two components of parturition: cervical ripening and myometrial contractility. The investigators will utilize transvaginal ultrasound to assess the changes in the cervical tissue, and non-invasive trans-abdominal uterine EMG to assess the uterine muscle activity. The investigators will also look at the effect of progesterone on contraction frequency by tocodynamometer (TOCO), though EMG is expected to provide much more information.

The aim of this study is to investigate the possible use of calcium channel as a neuroprotectant in cases with PTL. This will be done by comparing the effect they have on cerebral blood vessels with the already established MgSo4. They have been proven superior to magnesium sulphate in tocolysis, and they possess the mechanism of action that would allow for their theoretical use as neuroprotective agents.

The purpose of this study is to determine whether a combination of evidence-based strategies can improve intrapartum and newborn care in facilities to reduce mortality among preterm infants. This will be a cluster randomized implementation science study across 23 facilities in Eastern Uganda and Western Kenya. Selected interventions will be supported in facilities to measure impact during the study period. These interventions are: a) data strengthening and data use activities; b) implementation of a modified WHO Safe Childbirth Checklist with an emphasis on preterm labor and preterm babies; c) simulation-based provider training and mentoring on key existing evidence-based practices to improve newborn outcomes; d) support of Quality Improvement (QI) cycles to identify and resolve facility-specific issues and bottlenecks. A two-stage design will be used where all study facilities will receive some aspects of the intervention initially, namely data strengthening and the modified checklist. Subsequently, the remaining interventions (QI cycles and simulation training of providers) will be rolled out to a randomly selected half of the facilities in the first stage. At a second stage, the remaining half of the facilities will receive the remaining interventions.

This is a pilot study to evaluate the tolerability and effects of maintenance gabapentin therapy on the rate of premature birth in women who have had preterm labor.

Pregnant women who have a shortened cervix and have previously had a premature baby are at increased risk for having another premature baby. This study will determine whether reinforcing the cervix with a surgical stitch can reduce the chance of a premature birth.

Membrane sweeping is a routine procedure in obstetrics in term patients. It has been shown to be effective in decreasing post term gestation and in increasing rate of spontaneous vaginal delivery when used in setting of induction of labor in nulliparous patients. The goal of this study is to determine if membranes sweeping in early labor is effective in improving delivery outcomes including decreasing rate of cesarean section.

The aim of our study is to assess the effect of vaginal progestrone on fetal and maternal doppler indices

It is already known that the risk of preterm labor in twin pregnancy before 37 week is 8-9 fold higher compared to singletons, and progesterone supplementation can decrease the incidence of preterm labor in singleton pregnancy. There were studies that used 200mg vaginal progesterone with no effect on the result So this study aims To examine the effect of prophylactic vaginal progesterone 400mg v.s 200mg for prevention of preterm birth in twin pregnancies
