Premature Rupture of Membranes at 34 to 37 Weeks' Gestation

Study Overview
=================
Brief Summary
-----------------
Prelabour rupture of membrane is deﬁned as rupture of membranes prior to the onset of labour. Approximately 8% of pregnant women at term experience PROM, but the decision as to how term PROM should be managed clinically remains controversial, and there is wide variation in practice with no clear consensus on what constitutes optimal treatment. Although for the majority of women labour will start spontaneously within 24 hours following term PROM, up to 4%of women will not experience spontaneous onset of labour within seven days.

Primary Purpose: Prevention
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: conservative group<br>patient assigned to the observation group will be assessed in the labor and delivery suite for 2 to 4 hours with continuous external fetal heart rate monitoring and tocodynamometry. In the absence of non reassuring fetal status , initiation of labor , or infection , these women will be transferred to antepartum room where maternal vital signs. Patients will be restricted to bed rest with bathroom privileges and remained hospitalized until delivary . | Procedure: follow up<br>* hospitalization and antibiotics<br>|
| Experimental: active group<br>Patients assigned to active management will receive induction of labour with intravenous oxytocin with use of controlled infusion pump Oxytocin will be administered by continuous intravenous infusion beginning at 0.5 mU/min , doubling the dose every 30 minutes to 2mU/min , and then increasing by 2 mU/min every 30 minutes there after until a satisfactory labor pattern is achieved. | Procedure: induction of labor<br>* oxytocin intravenous drip<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| the percentage of patients with chorioamnionitis | Clinical chorioamnionitis is defined in the absence of other causes of hyperpyrexia by a temprature of >38 C with either uterine tenderness , leucocytosis , maternal or fetal tachycardia , or foul smelling vaginal discharge | 24 hours |
