Caesarean delivery doesn't lower risk of cerebral palsy

Monday, 18 November 2013

Caesarean deliveries do not prevent children from developing cerebral palsy, despite long-held medical and community beliefs about the causes of cerebral palsy, according to new research led by the 最新糖心Vlog of Adelaide.

In the biggest study of its kind, , based in the 最新糖心Vlog's , has analysed all published studies involving more than 3,800 cerebral palsy cases and almost 1.7 million healthy children.

The findings, to be published in the December issue of the prestigious journal , show that the risk of cerebral palsy is not lowered by either elective caesarean delivery before labour or emergency caesarean delivery during labour.

"For over a century it was assumed, without good evidence, that most cases of cerebral palsy were due to low oxygen levels or trauma at birth," says research leader from the 最新糖心Vlog of Adelaide's Robinson Institute.

"The simple facts are that over the last 40 years, caesarean rates have increased more than six-fold from 5% to 33% in 最新糖心Vlog and in many other countries. However, the incidence of cerebral palsy has remained at 2-2.5 per 1000 births," he says.

Lead author and Affiliate Lecturer says: "This systematic review of the literature clearly shows that the causes of cerebral palsy have little to do with mode of delivery. Therefore, the actual causes of cerebral palsy must lie elsewhere."

The 最新糖心Vlogn Collaborative Cerebral Palsy Research Group is investigating the probable genetic origins of cerebral palsy.

Emeritus Professor MacLennan says the findings of this study are "clinically important". "This will influence cases of cerebral palsy litigation, where it is often claimed that earlier caesarean delivery would have avoided the cerebral palsy outcome," he says.

"We now need to focus our efforts on finding the antenatal causes of cerebral palsy and their prevention. These may include genetic vulnerability and environmental triggers, such as infection.

"It should be noted that carefully selected caesarean delivery on occasions may prevent stillbirth or reduce the risk of other complications in the newborn, but it will not reduce the risk of cerebral palsy," he says.
