What we have learned about scheduling elective repeat cesarean delivery at term.

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Perinatal Outcomes

Background:

• Optimal timing for delivery, especially for elective repeat cesarean deliveries, is a frequent clinical question.
• Recent research and redefinition of "term" (early, full, late, post) highlight outcome variations.
• Existing guidelines recommend full-term delivery for elective repeat cesareans.

Purpose of the Study:

• To review available data supporting the recommendation for full-term delivery in elective repeat cesarean cases.
• To analyze evidence regarding the optimal timing of delivery for women undergoing repeat cesarean procedures.
• To inform obstetric providers on best practices for timing elective repeat cesarean deliveries.

Main Methods:

• Review of existing literature and data on delivery timing for elective repeat cesarean.
• Inclusion of contributions from the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) Maternal-Fetal Medicine Units (MFMU) Network.
• Analysis of outcomes based on the redefined "term" gestational age categories.

Main Results:

• Growing consensus favors elective repeat cesarean delivery at full-term (39-40 weeks) over early-term.
• Data suggests heterogeneity in outcomes across different "term" designations.
• Evidence supports the American College of Obstetricians and Gynecologists' recommendation for full-term delivery.

Conclusions:

• Elective repeat cesarean delivery should ideally be performed at full-term to optimize outcomes.
• Understanding the nuances of "term" delivery timing is crucial for clinical decision-making.
• Further research and adherence to guidelines are important for improving maternal-fetal health.
