Filter by:This is an observational study of pregnant persons in threatened labor. The study device will record electromyography signals, then the signals will be examined to determine who is in true labor and who is in threatened labor. The two goals are: - To establish the thresholds for the Contraction Synchronization Index (CSI) and the False Labor Index (FSI) to be used by the Labor Status Monitor to diagnose in-Labor or Not-in-Labor for preterm patients with threatened labor - To obtain feedback from subjects and providers to assist with enhancing patient comfort and provider training.
Currently, transvaginal cervical length measurement is used to screen in asymptomatic pregnant women with a history of PTB. In symptomatic women, presenting with threatened PTB cervical length in combination with the fibronectin test is used to identify women at high risk to deliver preterm. However, the predictive capacity of transvaginal cervical length measurement is limited. In pregnant women with a history of PTB, it only identifies a proportion of women who will have recurrent PTB. For symptomatic women, 30-60% of these women admitted to the hospital, do not deliver within seven days, leading to overtreatment of these women. Cervical softening is precursor of cervical shortening, effacement and dilatation and therefore cervical softening is a promising new marker that is based on tissue elasticity. However, the predictive value of cervical softening and the relation with spontaneous PTB still has to be determined. With the newly developed Pregnolia® System cervical softness could be measured on a standardized and safe manner. This study could help to improve care for women with a history of spontaneous PTB.
Objective: This trial is designed to compare between the effectiveness of nifedipine plus magnesium sulfate (MgSO4) and MgSO4 alone for tocolysis in women with threatened preterm labor. Patient Population: The population will include pregnant women at gestational age between 28 and 31 weeks who are 18 years old or older and have signs of threatened preterm labor. Study Design: This is a single-center, prospective, randomized controlled clinical trial. A total of 264 women pregnant between 28 and 31 weeks having threatened preterm labor will be enrolled and randomized into two parallel treatment arms. Patients in the group A will receive nifedipine plus MgSO4, while patients in group B will MgSO4 only. Treatment: All patients will be randomized on the day of enrollment. Patients with threatened preterm labor will receive the respective tocolysis in each group. All patients will receive corticosteroids for lung maturity according to the local protocol. Primary outcome: Number of women not delivered within 48 hours of starting tocolytic therapy. Secondary outcomes: perinatal mortality, a composite of adverse neonatal outcomes, birth weight, days on ventilation support, length of admission in neonatal intensive care, prolongation of pregnancy more than 7 days, delivery after 37 weeks of gestation, number of days till delivery, maternal mortality, maternal infection, and harm to mother from intervention.

Threatened preterm labor (TPL) is defined by cervical changes and regular and painful uterine contractions occurring between 24 and 36 + 6 weeks of gestation that may or may not lead to premature labor and delivery. There is no reliable way to predict preterm delivery. The study's hypothesis is that the Premaquick® test can improve the prediction of preterm delivery. The investigators also want to compare this test with the Partosure® (Placental alpha microglobulin-1) test.
