Active clinical trials for "Obstetric Labor, Premature"

Ritodrine is the conventional and the only approved tocolytics in Korea(by KFDA), although it was withdrawn from the US market more than 10 years ago. As already known well, ritodrine has many side effects such as tachycardia, hyperglycemia, pulmonary edema and so on. When such complications of ritodrine appears, clinicians consider of using MgSO4 as substitute, but its use is off-the-label yet in Korea. Facing this discrepancy, the investigators want to compare the efficacy and safety of MgSO4 with ritodrine and prove that MgSO4 is not inferior to ritodrine as tocolytics. For the singleton and twin pregnancies between 24+0weeks and 34 completed weeks whose uterine contraction is more than 4 during 20 minutes period with their cervical ripening is more than 25%, the investigators randomise them in Ritodrine group or MgSO4 group. Then, the investigators will check the change of their interval of uterine contraction, degree of pain and the appearance of any side effects or treatment failure sign.

Preterm birth (PTB) is a major cause of perinatal morbidity and mortality. Worldwide, about 15 million babies are born too soon every year, causing 1.1 million deaths, as well as short- and long-term disability in countless survivors. Different strategies have been studied for prevention of spontaneous PTB (SPTB) in randomized controlled trials (RCTs), including progesterone, cerclage, cervical pessary, as well as lifestyle modification, such as smoking cessation, diet, aerobic exercise, and nutritional supplements. Most successful effort to reduce the incidence of SPTB have focused on asympatomatic women with risk factors, such as prior SPTB or short cervix. However, most SPTB occur in symptomatic women, i.e. women with preterm labor (PTL). Women with arrested PTL are at increased risk of SPTB. The cervical pessary is a silicone device that has been used to prevent SPTB. The leading hypotheses for its mechanisms are two: that the pessary helps to keep the cervix closed, and that the pessary changes the inclination of the cervical canal so that the pregnancy weight is not directly above the internal os. The aim of the study is to assess the efficacy of pessary in reducing preterm birth in women with arrested preterm labor

In France, threatened preterm labour concerns 6.5% of pregnancies and is associated with a premature birth in 25.4% of cases. After 48 hours effective tocolysis, patients do not receive any further treatment while their risk of premature birth has risen from 6.5% to 25%. A pessary is a silicone ring encircling the cervix. It was initially used as medical treatment of genital prolapse but studies were also conducted for pregnant women in 2 high-risk premature birth situations: cervical incompetence and twin pregnancies. The multicenter PECEP trial conducted by Goya and al. in asymptomatic short cervix patients between 18 and 22 weeks of gestation showed a significant reduction of premature birth before 34 and 37 weeks of gestation. Thereby, the investigator assume that use of pessaries in patients presenting a resolutive threatened preterm labor will also be effective. To evaluate this hypothesis, the investigator designed a randomized prospective single-center open clinical trial comparing pessary associated with standard care (1st group) versus standard care only (2nd group) in patients experiencing an episode of resolutive threatened preterm labor.

Patients diagnosed with arrested pre-term labor following tocolytics at 24-34 gestational weeks will be randomly allocated to receive either vaginal micronized progesterone 400 mg/day or no treatment.

The focus of this work is to improve antenatal care (ANC) and postnatal care (PNC) at the health center level in five districts in Rwanda (Bugesera, Burera, Nyamasheke, Nyarugenge, and Rubavu). 36 health centers in these districts are included in this cluster randomized control trial (RCT) of group ANC and PNC care to measure this alternative model's effects on gestational age at birth, survival of preterm and low birth weight infants at 42 days of life, and ANC and PNC coverage. To improve antenatal assessment of gestational age, nurses will be trained in obstetric ultrasound at 18 health centers. These facilities will also incorporate pregnancy testing with urine dipstick to be performed by community health workers in charge of maternal health to facilitate early entry into ANC. This trial will test the hypothesis that women who participate in this alternative model of group ANC will experience increased gestational age at birth, as compared to women who receive standard focused ANC. This study is a collaboration with the University of Rwanda, the Rwandan Ministry of Health (MOH), the Rwanda Biomedical Center, and UCSF. The group care model used in this study is Rwanda-specific model developed by a Rwandan technical working group. The model includes an individual clinical visit for the first antenatal visit, followed by three group visits spaced about 8 weeks apart throughout pregnancy and a postnatal group visit at approximately 6 weeks after birth. Women will be grouped into stable groups of approximately 8-12 women with similar due dates. A community health worker (CHW) and a health center nurse will work together as co-facilitators to lead each of the groups. Each group visit includes clinical assessment, education, and treatments as appropriate for the women who attend. The model is founded on facilitative leadership of the groups, in which the co-facilitators allow women's experiences and interests to drive the content and women are encouraged to help one another cope with obstacles to optimal health. Facilitators will be supported by master trainers who will visit health centers to observe group sessions and offer supportive feedback. Data collected in this trial will include measures of the satisfaction of both women and providers with the group care, content of care differences between standard and group care, and perinatal outcomes such as gestational age at delivery and 42-day preterm and low birth weight infant survival.

The purpose of this study is to investigate the efficacy and the safety of nifedipine compared to atosiban for treating preterm labor.

The purpose of this study is to investigate the efficacy of Indomethacin compared to Magnesium Sulfate (MgSO4) in reducing neonatal morbidity through a prospective double blind randomized clinical trial. The specific aim of the project is to test the hypothesis that Indomethacin, compared to MgSO4, will decrease the proportion of neonates diagnosed with major complications or death.

This study evaluates the addition of oral dydrogesterone to standard treatment in the treatment of preterm labor. Half of participants will receive oral dydrogesterone and standard treatment, while the other half will receive oral placebo and standard treatment.

The purpose of this research study is to determine the best medication to stop preterm labor. Recent studies have identify nifedipine and indomethacin as the two medications that are most likely to delay delivery for 48 hours, decrease maternal side effects and decrease some complications related to preterm delivery to the neonate. Both of these medications are commonly used to stop pre-term labor, therefore it has become our institution's standard to use these two medications in the setting of preterm labor. There have been limited studies comparing these two medications directly. A total of 450 participants will be asked to participate across all study sites.

Preterm birth remains a major health concern affecting up to 12% of all live births prior to 37 weeks gestation. As preterm birth can often be associated with infection our proposal is to evaluate in a randomized fashion antibiotics for women with advanced cervical exams.
