The induction of labor without a medical reason is associated with negative outcomes for mothers, including increased rates of cesarean sections, increased blood loss and longer hospital stay. Furthermore, the induction of no benefit to the newborn. The conclusion of research done by University of Rochester, USA.

As the number of scheduled deliveries continues to rise, it is important for doctors and mothers understand the risks associated with elective induction. The new findings only apply, however, the women have their first child.

"The benefits of a procedure must always outweigh the risks. If there are any medical benefits to induce labor, it is difficult to justify the habit of doing it electively when we know the increased risks to mother and baby," said Christopher Glantz The study's author and professor of Maternal Fetal Medicine at the Faculty of the University of Rochester.

In the last decade, scheduled deliveries have become common, with doctors who do elective inductions part of their routine obstetric care. The study's authors cite social reasons, such as requests for applications and convenience of patients, to the continuous increase in purely elective induction.

Doctors and patients believe that inducing labor is harmless, however, does not work as well as natural childbirth. From the birth of zero can increase the chances of problems.

"As a professional and mother, I know how it can be tempting to schedule labor and let life in order, but there is a reason for babies to remain in the uterus for some time," said Loralei Thornburg, an assistant professor specializing in maternal medicine to fetus. "Why put yourself and your child at risk need?"

The researchers found that about 34% of women who opted for elective induction of labor had to do a caesarean section, while only 20% of women who worked naturally underwent a cesarean section. Because elective induction, can be naively viewed as routine and without risk, when in fact it is a major surgery and like any surgery increases the risk of infection and respiratory complications, the need for additional surgeries, resulting in longer recovery time.

Furthermore, women who were induced had more bleeding - even after taking cesarean deliveries - and were in hospital longer than those who had vaginal delivery. The study authors estimate that for every 100 women who undergo elective induction, there is an additional expenditure of 88 days in hospital compared with the same number of women working spontaneously.

Besides the induction increase the risk to the mother, the researchers also found that it does not improve the health of newborns. In induced births, the babies were more likely to need oxygen immediately after birth. They were also more likely to require specialized care from members of the neonatal intensive care unit (NICU).

The study included 485 women who gave birth to her first child between January and December 2007, at Medical Center of Rochester.

Although elective inductions are not outside the standard of care, physicians should be aware of the risks and communicate them to women considering the procedure.

"Previous research has shown that premature labor was induced without a legitimate medical reason is risky, this study further confirms these results," said Thornburg.
