Induction of labor in twin compared with singleton pregnancies

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Reproductive Health

Background:

• Induction of labor is a common obstetric intervention.
• Twin pregnancies present unique considerations for labor management.
• Comparative data on labor induction outcomes in twin versus singleton gestations are crucial.

Purpose of the Study:

• To compare the likelihood of cesarean delivery in twin pregnancies versus singleton pregnancies undergoing labor induction.
• To evaluate the length of labor in twin pregnancies compared to singleton pregnancies when labor is induced.

Main Methods:

• Retrospective cohort study involving 100 twin pregnancies and 100 singleton pregnancies undergoing induction of labor.
• Data collected from a maternal-fetal medicine practice between 2005 and 2012.
• Primary outcome measured was the mode of delivery (vaginal or cesarean).

Main Results:

• No significant difference in cesarean delivery rates between twin (19%) and singleton (21%) pregnancies (P=.724).
• Labor duration to vaginal delivery was comparable: median 9.7 hours for twins versus 10.4 hours for singletons (P=.255).
• Twin pregnancy was not an independent risk factor for cesarean delivery upon adjusted analysis.

Conclusions:

• Induction of labor in twin pregnancies is associated with similar rates of cesarean delivery as in singleton pregnancies.
• The duration of labor following induction is comparable between twin and singleton gestations.
• These findings support the safety and efficacy of labor induction for selected twin pregnancies.
