New study on breech delivery in an upright position

I'm excited to announce the publication of the Frankfurt upright breech study, in which researchers compared upright versus dorsal maternal positioning. This study has been years in the making.

Objective:
To compare breech outcomes when mothers delivering vaginally are upright, on their back, or planning cesareans.

Methods:
A retrospective cohort study was undertaken of all women who presented for singleton breech delivery at a center in Frankfurt, Germany, between January 2004 and June 2011.

Results:
Of 750 women with term breech delivery, 315 (42.0%) planned and received a cesarean. Of 269 successful vaginal deliveries of neonates, 229 in the upright position were compared with 40 in the dorsal position. Upright deliveries were associated with significantly fewer delivery maneuvers (OR 0.45, 95% CI 0.31–0.68) and neonatal birth injuries (OR 0.08, 95% CI 0.01–0.58), second stages that were on average shorter (1 vs 1.75 hours), and nonsignificantly decreased serious perineal lacerations (OR 0.34, 95% CI 0.05–3.99). When upright position was used almost exclusively, the cesarean rate decreased. Serious fetal and neonatal morbidity potentially related to birth mode was low, and similar for upright vaginal deliveries compared with planned cesareans (OR 1.37, 95% CI 0.10–19.11). Three neonates died; all had lethal birth defects. Forceps were never required.

Conclusion:
Upright vaginal breech delivery was associated with reductions in duration of the second stage of labor, maneuvers required, maternal/neonatal injuries, and cesarean rate when compared with vaginal delivery in the dorsal position.
