EXPERIMENTALInterventions
Atosiban group will receive an atosiban bolus (6.75 mg) over 1 min then an intravenous infusion of 300mcg/min for 3 h followed by 100mcg/min for another 45h. If contractions continue or recur within 48 hours or the dilatation of the cervix progresses by 1 cm or more within 48 hours, atosiban will be stopped and the women will receive nifedipine as a 2nd line (see arm 2). If the second line fails and gestational age is less than 28 weeks, indomethacin will be administered as a 3rd line.
Nifedipine group: the initial dose will be 20 mg (one tab) orally every 20 min for 3 doses. If the contractions is inhibited, a maintenance dose of 20 - 40 mg every 6 h up to 48 h will be followed. If contractions continue or recur within 48 hours or the dilatation of the cervix progresses by 1 cm or more within 48 hours, nifedipine will be stopped and the women will receive atosiban as a 2nd line (see arm 2). If the second line fails and gestational age is less than 28 weeks, indomethacin will be administered as a 3rd line.
Eligibility Criteria
You may qualify if:
- Gestational age between 24 to 34 weeks which had been documented by a definite LMP and sonography up to 20 weeks.
- All women fulfilled the criteria of preterm labor. The diagnosis of preterm labor required the presence of 4 uterine contractions or more over 30 minutes, each lasting at least 30 seconds, and documented cervical change. The cervical criteria were met when either of the following was present:
- Nulliparous women: a single cervical examination demonstrating dilatation of 0 cm to 4 cm and effacement of at least 50%
- Multiparous women: a single cervical examination demonstrating dilatation of 1 cm to 4 cm and effacement of at least 50%.
- Provision of written informed consent
You may not qualify if:
- Chorioamnionitis
- Preterm rupture of membranes
- Vaginal bleeding
- Major fetal malformations
- Severe hypertensive disorders
- Intrauterine growth restriction (\< 5th percentile).
- Non-reassuring fetal heart rate
- Maternal contraindications
- Chronic hypertension
- Systolic blood pressure \< 90 mmHg
- Cardiovascular disease
- Elevated hepatic enzymes
- Congenital or acquired uterine malformation
