Labor and delivery following successful external cephalic version

Area of Science:

• Obstetrics
• Maternal-Fetal Medicine
• Perinatal Outcomes

Background:

• External cephalic version (ECV) is a procedure to turn a fetus from a breech to a cephalic presentation.
• Concerns exist regarding potential adverse effects of successful ECV on labor progression and delivery route.
• Understanding the impact of ECV on labor and delivery is crucial for informed clinical decision-making.

Purpose of the Study:

• To investigate whether successful external cephalic version is associated with prolonged labor.
• To determine if successful ECV increases the likelihood of operative delivery (vaginal or cesarean).
• To compare intrapartum variables and neonatal outcomes between successful ECV cases and controls.

Main Methods:

• Retrospective case-control study matching 38 successful ECV cases with 114 controls delivering spontaneously vertex fetuses.
• Matching criteria included gestational age, labor onset, prior vaginal delivery, and cervical dilation.
• Analysis of maternal demographics, intrapartum events, neonatal outcomes, and delivery route using Student's t-test and Fisher's exact test.

Main Results:

• No significant differences were observed in labor duration between successful ECV cases and controls (10.8 vs. 10.1 hours).
• The rates of operative vaginal delivery (3/38 vs. 1/114) and cesarean delivery (4/38 vs. 8/114) were similar in both groups.
• Neonatal outcomes, including Apgar scores and NICU admissions, did not differ between the groups.

Conclusions:

• Successful external cephalic version does not appear to prolong labor.
• The procedure does not increase the risk of operative vaginal or cesarean deliveries compared to spontaneous vertex presentations.
• ECV is a safe intervention with no adverse effects on labor duration or delivery route.
