Natural Delivery After a C-Section Often Successful: Study11/20/13
WEDNESDAY, Nov. 20, 2013 (HealthDay News) -- Nearly two-thirds
of women who had a cesarean delivery for their first child were
successful when they attempted a natural birth for their second
baby, British researchers found.
The study, published Nov. 20 in
BJOG: An International Journal of Obstetrics and
Gynaecology, used data on almost 144,000 British women who had
their first baby by C-section between 2004 and 2011. The
researchers found that 52 percent of them attempted a vaginal birth
for their second baby.
"This study shows encouraging results with the majority of women who attempted a natural delivery after a primary C-section being successful," journal deputy editor John Thorp said in a journal news release.
Of the women who attempted a vaginal birth for their second
baby, 63 percent had a successful delivery. Black women had a lower
success rate than white women (50 percent vs. 66 percent), and
women older than 34 had a lower success rate than those aged 24 and
younger (59 percent vs. 69 percent).
Women aged 24 and younger were more likely to attempt natural
delivery for their second child than women older than 34, the study
found. And Asian women and black women were more likely than white
women to attempt natural delivery for their second child.
The reason for a C-section in the first birth strongly
determined the likelihood of a successful vaginal delivery for the
second birth. Women with a history of failed induced labor were
almost twice as likely to be unsuccessful when attempting a vaginal
birth after previously having a C-section.
The researchers also found that the rates of attempted and
successful vaginal birth after an earlier C-section varied between
hospitals for reasons that could not be explained.
Study leader Hannah Knight said an informed discussion about
whether or not to attempt a vaginal delivery after a cesarean
section requires an assessment of the risk of emergency
"This paper provides valuable information both for women and the obstetricians and midwives caring for them," Knight, of the Royal College of Obstetricians and Gynecologists, said in the news release.
The majority of women with an uncomplicated first C-section are
candidates for a vaginal delivery the next time around, "but our
data found that only half of those women chose this option," she
