Elective Inductions in Women with Histories of Fast Labor Prove for Quicker Deliveries

SAN DIEGO, Cali., May 2, 2012 – Women with histories of fast labor who elect inductions have faster delivery times, delivering their previous pregnancies in about half the time. For women with such histories, an elective induction may not be warranted, avoiding cost and morbidity risk, according to researchers at Summa Health System in Akron, Ohio.   

“We believe that women with histories of fast labors should be properly educated about elective inductions and the costs and risks associated with the procedure,” said OB Informatics Administrator Tiffany H. Kenny, RN, of Summa Health System. “Though a shorter labor duration may draw women to elective inductions, those in labor with previous fast deliveries may want to consider the potential risks before inducing.”

Researchers looked at women who underwent elective inductions from January 2005 to June 2011. Two indications, including “fast” and “psychosocial,” served as the controls.

A total of 479 inductions with 801 previous deliveries were evaluated – 150 with histories of fast labor (Fast) and 651 psychosocial (PS) deliveries. Fast had a median previous total labor length of 5.5 hours (CI: 4.5-6), which was significantly shorter than PS (median 10 hours; CI 9-10.5; p<0.001). Subsequent delivery time from start to expulsion was significantly shorter (P<0.001) for Fast (6.8 hrs CI: 6-8) vs. PS (9.1 hrs CI: 9-9.7). Fast had a shorter time from induction start to labor onset (Fast median=3.5 hrs CI: 3-4.8; PS median= 6.8 hrs CI: 6.3-7.6), but a similar second stage (Fast median=18 minutes CI: 13-22; PS median= 20 minutes CI: 18-22).

The research titled “Induction of Labor in Women with a History of Fast Labor,” was selected for a poster presentation at the 60th Annual Clinical Meeting of the American College of Obstetricians and Gynecologists in San Diego from May 5 to 9. Bradford W. Fenton, M.D., Ph.D., Erica L. Melrose, D.O., and Tiffany H. Kenny, RN, are the authors.

The poster will be on display from 3 p.m. to 4 p.m. on May 8 in Exhibit Hall H of the San Diego Convention Center at station 54. A representative from Summa will be available to answer questions or interviews can be arranged before, after or during the conference with the authors.
