Outcome Measures

Primary Outcomes (1)

  • delaying labor

    for more than 48 hours after starting treatment

Secondary Outcomes (3)

  • drugs side effects

    within the first 48 hours after treatment

  • obstetrical (number of days to delivery, gestational age at delivery, mode of delivery)

    within 24 hours after delivery

  • neonatal (Apgar score, sepsis, IVH, NEC, RDS, DEATH)

    within 30 days from delivery

Study Arms (2)

1

EXPERIMENTAL
Drug: Atosiban

2

EXPERIMENTAL
Drug: Nifedipine

Interventions

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.

1

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

Sexfemale
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

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
