Twin delivery

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Perinatology

Background:

• Twin pregnancy incidence has risen due to assisted reproductive technologies.
• Twin gestations present unique challenges in labor and delivery, with higher mortality rates than singletons.
• Existing research often prioritizes preterm birth and growth restriction over delivery management.

Purpose of the Study:

• To review and update guidelines for twin delivery management.
• To discuss indications for Cesarean section in twin pregnancies.
• To evaluate optimal delivery methods for the second twin, particularly non-vertex presentations.

Main Methods:

• Review of epidemiological data and clinical guidelines for twin gestations.
• Analysis of operative interventions and delivery techniques for the second twin.
• Discussion of evidence regarding elective Cesarean section versus vaginal delivery for non-vertex second twins.

Main Results:

• Vaginal delivery of vertex-presenting twins is safe when guidelines are followed.
• Internal version and breech extraction may be safer than external cephalic version for non-vertex second twins.
• Evidence for elective Cesarean section in specific scenarios, like low-birth-weight non-vertex twins, requires further randomized controlled trials.

Conclusions:

• Optimized management of twin labor and delivery is crucial for improving outcomes.
• Specific protocols for monitoring, operative interventions, and timing are essential.
• Further research is needed to establish definitive best practices for complex twin delivery scenarios.
