简要总结
The goal of this randomized controlled trial is to examine the efficacy of combining castor oil ingestion with extra-amniotic single balloon catheter for cervical ripening on time from induction to delivery in multiparous women.
The main question it aims to answer are:
Does the addition of the use of castor oil to extra-amniotic single balloon reduce the time until birth? Does the addition of the castor oil affect other perinatal outcomes during childbirth? Are the side effects of the castor tolerated by the mothers? Participants will be randomly divided into 2 groups: the study group will drink a mixture of 60 ml of castor oil mixed with 140 ml of orange juice. Thirty minutes later, extra-amniotic single balloon catheter will be inserted above the internal cervical os and filled with 60 mL of normal saline.
In the control group, the catheter will be inserted into cervical canal without ingestion of castor oil.
详细描述
The rate of labor induction has increased up to 25.7% in 2018 for several demographic and obstetric reasons.
Various methods are used to induce labor worldwide, including natural, mechanical and pharmacological agents. of all methods balloon catheters were proven to cause fewer adverse perinatal events.
Though induction is considered a safe and effective procedure, it may lead to a prolonged labor which is associated with complications such postpartum hemorrhage, infection, and operative delivery.
Based on these data several studies have examined the combinations of balloon catheters with other pharmacological agents on labor durations. The results were inconsistent, and several reports showed that the combination reduced significantly the length of labor. Nevertheless, pharmacological agents may be associated with adverse events including uterine hyperstimulation, placental abruption, and postpartum hemorrhage, though the overall risk is small.
Castor oil, extracted from the seeds of Ricinus communis plant, is a natural effective substance for induction of labor. it's considered a safe and inexpensive though the exact mechanism by which it induces labor is still unclear.
