Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Objectives- To compare changes in labour-associated maternal and fetal hormone levels during breast stimulation, balloon induction and spontaneous labour. To compare efficacy and safety of labour induction methods in women with previous caesarean section.

Design- Participants were randomized to undergo induction of labour by breast stimulation or intracervical balloon compared to spontaneous labour (controls).

Setting- A single tertiary hospital Population- women at term, with previous caesarean section

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Maternal serum levels of oxytocin, prostaglandin F2α, prostaglandin E2, prolactin, estradiol and cortisol levels were analyzed at 0, 3 and 6 hours post induction initiation, including the two groups catheter balloon and breast stimulation and controls in spontaneous labor. Fetal umbilical cord hormones were measured in the three mentioned above groups. Clinical outcomes were documented in the two induction groups.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

induction of labour by breast stimulation

women at term with previous cesarean section and an indication to induce labor. In order to induce labour by breast stimulation, an electrical pump was used. The cup was alternated between the nipples every 15 minutes, with a pause of 15 minutes after each 30 minutes, with a total induction time of 6 hours.

Group Type ACTIVE_COMPARATOR

induction of labor by breast stimulation

Intervention Type DEVICE

induction of labour by catheter balloon

women at term with previous cesarean section and an indication to induce labor. In the catheter balloon group, a 16-F Foley catheter was inserted into the cervical canal and inflated with 60 cc sterile saline solution and was kept in place for 12 hours.

Group Type ACTIVE_COMPARATOR

Intervention Type DEVICE

spontaneous labour

women in latent phase of spontaneous labour .
