Brief Summary

Preterm labor is defined as regular contractions of the uterus resulting in changes in the cervix (effacement and dilatation) that start before 37 weeks of pregnancy. (1) Although preterm labor constitutes only 10% of total labors, yet 70% of infant's mortality is related to prematurity. It is therefore one of the international indices in assessment of health condition worldwide. Human Chorionic Gonadotropin (H.C.G.) is a heterodimeric glycoprotein produced primarily in the placenta and has multiple endocrines, paracrine and immunoregulatory actions. (3) The importance of H.C.G. in maintenance of early pregnancy has been widely accepted, reports have highlighted a potential role of H.C.G. in maintaining uterine quiescence in the third trimester. H.C.G. exerts a potent concentration dependent inhibitory effect on human myometrial contractions. (4) Recent data suggests that H.C.G. might have a role as an endogenous tocolytic agent in normal pregnancy. A significant decrease in serum H.C.G. level was found 2-3 weeks before the spontaneous onset of labour. This might contribute to increasing the contractility in the uterine muscle and gradually initiating the onset of labour. (5)

Outcome Measures

Primary Outcomes (1)

  • Tocolysis

    Tocolysis will be considered successful when contractions ceased and delivery will be delayed by 48 hrs giving time to the administered corticosteroids to accelerate fetal lung maturation

    48 hours

Study Arms (2)

HUMAN CHORIONIC GONADOTROPIN (HCG) Group

ACTIVE COMPARATOR

H.C.G. will be given in Group A and in a dose of 5000units intramuscular injection followed by a drip of 10,000 units in 500ml of dextrose 5%, at the rate of 20 drops per minute. Half hourly assessment of uterine contractions, maternal vital signs, fetal heart rate monitoring will be done.

Drug: human chorionic gonadotropin (hCG)

Magnesium Sulphate(MgSO4) Group

ACTIVE COMPARATOR

4gm of MgSO4 will be given in Group B as intravenously as continuous dose followed by 2gm/hr till uterine quiescence is achieved.

Drug: Magnesium sulfate

Interventions
