Since the mid-1990s, the number of twin births which has been delivered via caesarian section method in the US have rose dramatically. This new study conducted by researchers from Calfornia have said that while at some times, the positions of the babies during the delivery or other delivery complications make a normal spontaneous delivery impossible and dangerous, there is also a large increase in the case of caesarean sections for those mothers who are healthy, and whose babies are well positioned, calling for a normal spontaneous delivery.
“There seems to be a very liberal approach to cesarean section with twins that has evolved over the last decade,” noted Dr. Mark Landon, the head of obstetrics and gynecology at Ohio State University in Columbus. “The numbers are pretty dramatic in terms of the fact that three-quarters of twins undergo cesarean section now,” According to Dr. Landon who was not involved in the study.
In 2008, there has been a recorded 75% increase in the incidence of caesarean sections of healthy moms as compared to just 53% last 1995. This adds up to a five percent yearly increase in the proportion of twins which are born via C-section at a national level.
The trend couldn’t be explained with the increase in complications, mothers with harmful conditions or unsafe position of the babies in the stomach, i.e. breech position wherein the feet of the babies are at the lower part of the uterus, instead of the head.
The rate of performing c-section has also been noticed to increase eve in healthy women with a very low risk of delivery complication, and even among women with correctly positioned babies. The increase rose from about a third to almost half at the end of the body. According to Landon, “in those cases, “there is really no evidence that cesarean delivery confers a benefit to either the mother or the infant.”
According to the findings published in Obstetrics and Gynecology, the results are also congruent to other research findings which suggest that the rate for babies delivered via c-section has also been climbing even for non-twin pregnancies. Today, C-section deliveries account for about one-third of all births in the U.S.
Researchers are not sure why such incidence is happening. Some people have suggested that obstetricians may be giving up on vaginal deliveries and switched to c-sections, or women may be requesting c-sections so that they can have greater control over their babies when their babies are born. However, experts noted that having caesarean section is riskier than normal delivery since it gives rise to risks of bleeding, infection, as well as bowel and bladder problems. The procedure also relates to higher hospital costs and longer hospitalization.
“We know that sometimes they’re appropriate and going to be beneficial… but in some instances there’s no clear reason for them and it can potentially cause problems for the mother or baby,” according to Dr. Henry Lee from the University of California, San Francisco, who is part of the research group.
Dr. Lee also concluded that “It’s a priority in our country now to decrease the cesarean rate overall.”
