简要总结
This is a randomized study evaluating the impact of pre-hospital cervical ripening with a transcervical Foley balloon before labor induction in full-term pregnancies on the length of inpatient labor induction and maternal satisfaction with the labor induction process. The investigators hypothesize that women who receive pre-hospital cervical ripening will have a shorter duration of inpatient labor induction as compared to women without pre-hospital cervical ripening.
详细描述
Labor induction is a common procedure among pregnant patients at term. This process involves a period of cervical preparation ("ripening") for women who have an "unfavorable" cervical examination at the time labor induction is scheduled. Cervical ripening may take place with pharmacologic or mechanical strategies, which at this time are traditionally administered on an inpatient basis. This process can 24 or more hours, resulting in a lengthy hospitalization with the associated costs and frustrations for both patients and L&D staff.
The proposed study is a randomized, controlled trial to explore the following research question: Among women with full-term pregnancies requiring labor induction, does pre-hospital, outpatient cervical ripening reduce the amount of inpatient time needed to achieve delivery as compared to no pre-hospital cervical ripening? As a secondary objective, we also wish to explore if outpatient cervical ripening is acceptable to patients.
This study will involve randomizing eligible and consenting women who have been scheduled for labor induction by their obstetrical providers into a pre-hospital cervical ripening (intervention) group or a no pre-hospital ripening (control) group. A trans-cervical Foley balloon (TCFB) will be used for outpatient pre-hospital cervical ripening in women randomized to the intervention group. No pre-hospital ripening will be performed for women in the control group. Both groups will be admitted for induction as scheduled and will undergo labor induction according to a specified, Bishop-score based induction protocol, which may or may not include a TCFB. We will compare the duration of inpatient stays from admission until delivery between the groups as well as satisfaction with the pre-hospital period and labor and delivery experience. Maternal and neonatal outcomes will also be compared between the two groups.
