Highndry the Cochrane Center is a global independent network of researchers, professionals, patients, carers, and people interested in health. Many of the contributors are world leaders in their fields - medicine, health policy, research methodology, or consumer advocacy - and their groups are situated in some of the world's most respected academic and medical institutions.
As such it was a review of research that utilized Randomised controlled trials that met the selection criteria and from the review of the literature/research they produced their findings:
1. The use of an enema does not lessen or increase the infection rates for mothers or babies.
2. It does not shorten labour.
3. It does not ensure that an episiotomy wound doesn't break if the mother needs to pass a large bowel movement after the delivery.
Prior to publishing their findings :
Enemas were commonly believed to:
1. Speed up labour ( help with inducing contractions and helping to bear down ( pushing))
2. Make the delivery cleaner for those caring for the mother in labour
3. Diminish the newborn's and mother's chances of picking up infections
4. Reduce the discomfort of passing a large bowel movement soon after giving birth
5. Minimise the chances of breaking open an episiotomy wound from passing a large bowel movement soon after the delivery
