Intrapartum management of twin gestation

Area of Science:

• Maternal-Fetal Medicine
• Obstetrics
• High-Risk Pregnancy Management

Background:

• Increased incidence of multiple gestations due to widespread ultrasound use.
• Early diagnosis allows for placentation determination and fetal growth monitoring.
• Need for clear guidelines in intrapartum management of multiple gestations.

Purpose of the Study:

• To outline optimal intrapartum management strategies for multiple gestations.
• To address controversies regarding the route of delivery in twin gestations.
• To provide evidence-based recommendations for managing nonvertex second twins.

Main Methods:

• Antenatal assessment including ultrasound for placentation and fetal growth.
• Intrapartum evaluation with ultrasound for fetal presentation and size.
• Continuous fetal heart monitoring and maternal complication assessment (anemia, hypertension, polyhydramnios).

Main Results:

• Cesarean delivery is recommended for gestations with more than two fetuses.
• Vaginal delivery is generally favored for vertex-vertex twin pairs.
• Planned vaginal delivery of the mature nonvertex second twin is supported with appropriate monitoring and preparation.
• Elective cesarean section is advised for nonvertex second twins < 1800 gm.

Conclusions:

• Intrapartum management of multiple gestations requires a comprehensive antenatal and intrapartum approach.
• Current evidence supports planned vaginal delivery for carefully selected twin gestations, including nonvertex second twins.
• Individualized management based on fetal presentation, estimated weight, and maternal status is essential.
