Overview
Brief Summary
The target population for our study is women who present for induction of labor. If there is a decision by the obstetrical team to place a mechanical dilator for cervical ripening, the obstetrical team will notify the research staff so that the patient may be screened for the study. If the subject is eligible for the trial, written informed consent will be obtained by person-to-person contact. The PI, study coordinator, or a collaborator will be responsible for the informed consent procedure. After informed consent is obtained and Dilapan-S is placed, the patient will be randomized to the Outpatient or the Inpatient group.
Detailed Description
Group Assigned to Outpatient Cervical Ripening After Dilapan-S® placement, subject will be monitored for at least 30 minutes. If no contraindications, such as tachysystole, active vaginal bleeding, rupture of membranes or nonreassuring fetal testing (defined as minimal or absent variability, abnormal baseline, or presence of decelerations) evidence of labor, or other serious medical conditions deemed by the clinical staff or the attending physician to preclude outpatient cervical ripening develop after insertion, the subjects will be randomized. After randomization subject will record the pain she experienced during insertion in the patient's survey (see Appendix 3). Those subjects randomized to outpatient ripening will be given the option to either return home or to stay in a hotel if transportation is an issue. The cost for the hotel will be covered by the study budget. Subjects will be allowed to ambulate, shower and perform regular activity during that period. "Nothing per vagina" will be allowed (incl. intercourse, tampons etc.). Group Assigned to Inpatient Cervical Ripening Subjects randomized to inpatient management will be admitted to L\&D unit and standard clinical protocol will be initiated for cervical ripening and labor induction. During the period of 12 hours of cervical ripening subject is to remain "nothing per os" (NPO), "nothing per vagina" and undergo continuous fetal heart rate monitoring. No other interventions are to occur during this period of 12 hours, unless clinically indicated. Labor Induction and Labor Management of the subject after the initial 12 hours of pre-induction or following the earlier removal or spontaneous expulsion of the dilator will be the same for both groups and at the discretion of the clinical team. Additional ripening (mechanical or prostaglandins) and/or oxytocin may or may not be needed. If needed, duration, type and dose of additional ripening agents and oxytocin will be documented. Routine intrapartum care will be provided and relevant data collected by the subject's managing obstetrical team.
