简要总结
This randomized controlled trial will compare two methods of induction of labour in women with term pregnancy: concurrent use of a Foley catheter and PGE2 vaginal pessary versus sequential use of the two methods. The study will assess whether using both methods concurrently is more effective and safe than using them sequentially. The primary focus is the rate of vaginal delivery within 24 hours after initiation of induction. Participants will be women with term pregnancy (37-42 weeks) admitted for induction of labour without significant comorbidities.
详细描述
Induction of labour is commonly performed when continuation of pregnancy is considered less beneficial than delivery. This randomized controlled trial will compare the effectiveness and safety of two approaches to cervical ripening and induction of labour in women with term pregnancy.
Eligible participants will have a gestational age of 37-42 weeks and will be admitted to the hospital for induction of labour without significant comorbidities. Gestational age will be confirmed using a dating scan or last menstrual period, and baseline fetal monitoring will be performed using cardiotocography (CTG) before induction.
Participants will be randomly allocated to one of two treatment groups.
In the concurrent group, a PGE2 vaginal pessary and a Foley catheter will be inserted concurrently. The Foley catheter balloon will be inflated with 30 mL of normal saline.
In the sequential group, the Foley catheter will be inserted first, followed by insertion of the PGE2 vaginal pessary 12 hours later.

入选标准
- •Pregnant women aged 18-40 years with a singleton cephalic fetus between 37 and 42 weeks of gestation who require induction of labour, with BMI 20-35 kg/m², intact membranes, and reassuring cardiotocography (CTG), will be included.
排除标准
- •Women with meconium-stained liquor, antepartum haemorrhage, low-lying placenta defined as placental edge less than 2 cm from the internal os on ultrasonography, pre-eclampsia, fetal growth restriction, previously scarred uterus, estimated fetal weight greater than 4 kg on ultrasound, cephalopelvic disproportion, or liquor abnormalities will be excluded.
研究组 & 干预措施
Concurrent Induction of Labour
Participants will receive concurrent cervical ripening with a PGE2 vaginal pessary and insertion of a Foley catheter. The Foley catheter balloon will be inflated with 30 mL of normal saline. Both interventions will be initiated concurrently at the start of induction of labour.
干预措施: Foley Catheter (Device)
Concurrent Induction of Labour
Participants will receive concurrent cervical ripening with a PGE2 vaginal pessary and insertion of a Foley catheter. The Foley catheter balloon will be inflated with 30 mL of normal saline. Both interventions will be initiated concurrently at the start of induction of labour.
干预措施: PGE2 Vaginal Pessary (Drug)
Sequential Induction of Labour
Participants will receive sequential cervical ripening with a Foley catheter followed by insertion of a PGE2 vaginal pessary 12 hours later. The Foley catheter will be inserted first, followed by the PGE2 vaginal pessary after 12 hours.
