Double-balloon catheter versus dinoprostone insert for labour induction: a meta-analysis

Area of Science:

• Obstetrics and Gynecology
• Reproductive Medicine

Background:

• Labor induction is a common obstetric procedure.
• Cervical ripening is a critical step in labor induction.
• Various methods exist for cervical ripening, including pharmacologic and mechanical approaches.

Purpose of the Study:

• To compare the efficacy and safety of a double-balloon catheter versus a dinoprostone insert for labor induction.
• To evaluate key outcomes such as vaginal delivery rates, cesarean section incidence, and neonatal well-being.

Main Methods:

• A systematic review and meta-analysis of randomized controlled trials (RCTs) were conducted.
• Searched major databases (PubMed, MEDLINE, Embase, etc.) from 1985 to April 2018.
• Included RCTs comparing double-balloon catheter and dinoprostone insert for labor induction in singleton pregnancies.

Main Results:

• Five RCTs involving 603 women were analyzed.
• No significant difference in vaginal delivery within 24 hours or cesarean section rates was found.
• The dinoprostone insert group required less oxytocin but had higher rates of excessive uterine activity and concerning neonatal umbilical cord pH levels.

Conclusions:

• Both double-balloon catheter and dinoprostone insert demonstrate comparable efficacy for labor induction.
• The double-balloon catheter may be a safer option due to a lower incidence of adverse neonatal outcomes.
