Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at 100 pregnant women with a single baby who are experiencing preterm labor between 24 and 34 weeks. Researchers aim to find which factors help predict whether a short course of tocolysis (medication to delay labor) can postpone delivery by at least 48 hours. The goal is to better understand who is most likely to benefit from this treatment.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could help doctors identify which women are most likely to benefit from tocolysis, potentially improving preterm labor management.
What could go wrong
This is an observational study, not a treatment trial. It identifies associations, not causes, and results may not apply to all populations.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

All participants will receive short-term tocolytic therapy according to the unit protocol. * The choice of tocolytic agent (., Magnesium sulphate ) will be determined by the treating physician. * Tocolysis will be administered for a maximum duration of 48-72 hours. * Antenatal corticosteroids (Betamethasone amp 12mg once daily for 2days) will be administered to eligible participants to enhance fetal lung maturity. * Failure documented when there is efficient uterine contractions more 4/10mins each one lasts more than 40 seconds, and there was progressive cervical dilatation more 3cm

Inclusion Criteria: * Age from 18 to 45 years old. * Singleton Pregnancy * Gestational age between 24 and 34 weeks, confirmed by last menstrual period and/or first-trimester ultrasound. * Diagnosis of preterm labor, defined as Regular uterine contractions (≥4 in 20 minutes recorded in CTG) with a documented change in cervical dilation (e.g., from\<1 cm to ≥2 cm) or, in nulliparous women, a dilation of ≥2 cm * Intact membranes at the time of presentation. Exclusion Criteria: Established preterm labor (efficient uterine contractions 4/10mins each one lasts more than 40 Seconds recorded in CTG, with cervical changes (dilatation\>4cm, effacement\>80%)). * Evidence of chorioamnionitis or intrauterine infection. * Preterm premature rupture of membranes (PPROM). * Maternal medical disorders contraindicating tocolysis, such as severe preeclampsia, significant cardiac disease, or uncontrolled diabetes mellitus. * Contraindications to continuation of pregnancy, including placental abruption or placenta previa with bleeding. * Vaginal bleeding of unknown origin" as a specific exclusion criterion, as it may indicate abruption or other pathologies.
