Women having a non-emergency caesarean birth have double the risk of illness or even death compared to a vaginal birth, according to a study from Latin America published today on bmj.com.
However, the researchers found caesarean delivery prevented deaths in breech born babies.
The risks linked to caesarean births (whether chosen by the woman or her clinicians) are higher, regardless of variables such as demographics, medical and pregnancy history, gestational age of the foetus, pregnancy complications, where the baby is born and the skills of those helping to deliver the baby.
Researchers randomly selected eight Latin American countries and from those, 120 also randomly selected health facilities provided complete data on 97,307 deliveries of babies during a three-month study period. These data came from the Latin American component of the WHO Global Survey on Maternal and Perinatal Health, specifically carried out for this study in 2005.
They wanted to compare the risks and benefits of caesarean delivery compared to vaginal delivery. Of the 97,307 cases, 33.7% were caesarean and 66.3% vaginal. Overall, perinatal outcomes were good in these 120 hospitals, not far from those in developed countries.
They found that a woman having a caesarean delivery had twice the risk of illness and mortality (including death, hysterectomy, blood transfusion and admission to intensive care) as a woman having a vaginal delivery.
There was a five times higher risk of having to have antibiotic treatment after birth for women who had a caesarean delivery (elective or decided by clinicians) than those who had a vaginal delivery.
Risk of having to stay in a neonatal intensive care unit for newborn babies who were born head-first was doubled after a caesarean delivery compared to a vaginal birth.
The authors also found that the risk of neonatal death was also significantly increased (mo
