Filter by:This study compares safety and efficacy between repetitive hourly dose of oral misoprostol and two hourly dose oral regimens for cervical ripening and labor induction.
Labour induction is a frequent obstetric intervention (~20%). Prostaglandins (PGs) are effective agents, but gastrointestinal (GI) intolerance has limited use to non-oral routes. The traditional oxytocin "drip" requires intravenous (IV) use and discourages mobility. Misoprostol, a PG analogue, is marketed for oral treatment of GI disorders, but initiates uterine contraction, an undesirable GI side effect. Recently, there has been a research "boom" on vaginal misoprostol use in pregnancy to induce term labour drawing on this "side effect:". The principal investigator has led one of three groups worldwide which has published on oral misoprostol to study effectiveness, GI tolerance, and safety for mother/baby in term labour induction. Cost per patient has been less then one percent that of other PGs, even less than IV oxytocin.
Nowadays, more and more women embark on pregnancy with previous Caesarean scar. One in five pregnancies requires induction of labour. The use of non-pharmacological methods (methods without using medication) has been gaining popularity for women who are not good candidates, such as women with previous Caesarean scar, for an induction with medications such as prostaglandin. Labour induction with prostaglandin carries higher risk of uterine rupture and thus it is not routinely offered to women with previous Caesarean delivery in Sibu Hospital. Non-pharmacological methods of induction of labour appear to be safe in women with previous Caesarean delivery. However, various methods are available and the efficacy among them remain in doubt. In Sibu Hospital, membrane sweeping, which is a type of non-pharmacological method, is routinely offered to women with previous Caesarean delivery who require induction of labour. However, membrane sweeping may not exert its labour induction effect immediately and the delivery may be delayed by up to 8 days. This may render a proportion of women to resort to repeated Caesarean section for failed induction. Transcervical Foley catheter insertion is another non-pharmacological methods for labour induction. Foley catheter, which is made from latex rubber, is inserted into the womb. The balloon will be inflated and this put pressure on the cervix and encourages dilatation. This method may successfully stimulates labour and the catheter falls out once the cervix dilates to 3 centimeters. The benefits of the Foley catheter: - A favourable and safe option for mothers who are hoping for a vaginal birth after Caesarean. It is estimated that 4-7 in 10 women with previous Caesarean undergoing labour induction with Foley catheter will have successful vaginal births. - Cause the cervix to mechanically open without involving medication. - Reduced risk of uterine rupture compared to induction with prostaglandin. - Less risk of fetal distress compared to induction with prostaglandin. The risks of Foley catheter: - Vaginal bleeding (1.8%) - Pain requiring removal of catheter (1.7%) - Baby moving from head down to breech (1.3%) - Fever (1%) which is lower than induction with prostaglandin. - The risk of uterine rupture is similar to women undergoing spontaneous vaginal birth after Caesarean. The aim of this study is to compare the effectiveness of two types of non-pharmacological methods, ie. membrane sweeping and transcervical Foley catheter for induction of labour in women with previous Caesarean delivery.
It is currently unknown if there is a way to decrease the risk of cesarean delivery when undergoing cervical ripening and induction of labour. Some research suggests a Foley catheter placed through the cervix and filled to 80cc may decrease this risk. We wish to run a large scale trial to see if Foleys filled to 80cc decrease the risk of Cesarean section compared to the commonly used medication for cervical ripening, prostaglandins. Before we can undertake a large trial, we need to do a pilot to see if women will agree to participate in this type of study. As well, a pilot will help with trouble shooting prior to a large trail, to improve the chances of successfully answering this clinically important question.
The purpose of this study is to compare pharmacokinetics of two formulations of misoprostol following single dose administration in adult women being given misoprostol for cervical ripening and induction of labour.
