19659007] Pregnant women are more likely to have complications during labor and cesarean deliveries than during vaginal births, and a new study offers fresh evidence that older mothers are at risk.
Cesarean delivery rates, or C-sections, have survived in developed world at more than 20 percent of births, although the World Health Organization recommends this operation for nearly 10 to 15 percent of cases if the firstborn or baby is at risk. While C-sections can be life-threatening, these procedures carry risks such as infection, excessive bleeding, damage to reproductive organs and blood clots.
For current study, researchers want to get a clearer picture of how often complications are the result of surgery compared to the underlying medical problems that mothers may be able to get operation. To do so, they analyzed data on 1,444 women who experienced serious complications after delivery that were unrelated to existing health problems. They are also looking at a team comparing 3,464 women without complications.
Women with C-section are 80 percent more likely to have complications than those delivered vaginally, researchers report on the CMAJ journal. And women at age 35 with C-section are almost three times more likely to have serious complications.
"Generally, delivery is safe," said senior study author Dr. Catherine Deneux-Tharaux of INSERM in Paris by email. "However, in a minor case, serious complications can occur in the mother at or soon after delivery. This occurs in about 1.5 percent of the delivery and the main cause is the primary hemorrhage . "
As women age, uterine muscle loses the ability to contract well, and it can contribute to heavy bleeding after the C-section of older women, Deneux-Tharaux said
"The physiological stop at bleeding after birth involves a contraction of the uterus;
About 85 percent of the complications are bleeding after delivery.
Nearly 36 percent of women with serious complications delivered by the C-section, compared with 18 percent of mothers without complications.
Women of all ages have had a higher risk of complications in the C sections performed after mothers work, a decision that is often done because of medical issues that arise for women or For their babies.
Mothers under 25 years of age have C-section done after that Beginning with labor is 60 percent more likely to have complications than their counterparts with vaginal delivery.
Pregnant women 35 or older with C After-labor sections are four times more likely to have complications than mothers over 35 with births.
For C-sections scheduled before women went to work, however, the oldest women in the study had increased risk of complications. Mothers 35 and older with C-sections without first effort are five times more likely to have serious complications than mothers with births.
Study is not a controlled experiment designed to prove how or how C-sections can cause complications or to determine how the timing of these operations is related to the start of labor may affect the risk. Researchers also recognize that they can not count on every situation when a pre-existing problem or complication may be the reason that a C-section is performed.
However, the results should give women another reason to be careful about scheduling a C-section unless they are definitely necessary, said Laura Schummers, a researcher at the University of British Columbia in Vancouver who is not involved in the study.
"The risks of cesarean delivery accumulate in a woman's life, with the first cesarean increase in risk of subsequent pregnancies, increasing the likelihood of a second C-section, and increasing complications in the second cesarean , "Schummers said via email. "As more women permit pregnancy at age 35 or more, this study emphasizes the importance of good decision-making in the C-section, especially for women in this group who older people will have additional pregnancies.
