Study summary

Prolonged rupture of membranes has been associated with increased risk of chorioamnionitis and endometritis. In this study the investigators will investigate whether an early intervention to augment labor with oxytocin is superior to expected management for spontaneous delivery (up to 24 hours).

Read the detailed description

Prelabor rupture of the membranes (PROM) refers to rupture of the fetal membranes prior to the onset of regular uterine contractions.

PROM at term can be managed actively by induction of labor or expectantly by waiting for the onset of a spontaneous labor. Several studies have shown an association between expectant management and higher rates of maternal and neonatal adverse outcomes, especially infections. Furthermore, expectant management has been shown to increase the risk for cesarean deliveries (CD), chronic lung disease, cerebral palsy and neonatal mortality. It is suggested that the risk for those complications increase proportionally with the longer the duration of ruptured membranes. Others disagree with those associations.

In this study the investigators will investigate whether early administration of oxytocin is superior to expectant management of 24 hours in patients with PROM at term, in terms of time to delivery and maternal and neonatal adverse outcomes, regardless of bishop score.

Study arms

  • Experimental
    Immediate oxytocin infusion

    Once the patient will arrive at the maternity ward with prelabor rupture of membranes, she will receive oxytocin for augmentation of labor.

    Drug: Oxytocin

  • Experimental
    Expectant management for 24 hours

    Once the patient will arrive at the maternity ward with prelabor rupture of membranes, we will wait for spontaneous delivery to occur. After 24 hours of rupture of membranes, the woman will receive oxytocin for augmentation of labor.

    Drug: Oxytocin

Interventions

  • The drug wil be adminisrate for augmentation of labor at admission.

    Also known as: pitocin
