High Quality Content by WIKIPEDIA articles! Ventouse is a vacuum device used to assist the delivery of a baby when the second stage of labour has not progressed adequately. It is an alternative to a forceps delivery and caesarean section. It cannot be used when the baby is in the breech position or for premature births. This technique is also called vacuum-assisted vaginal delivery or vacuum extraction (VE). The use of VE is generally very safe, but it can occasionally have negative effects on either the mother and the child.
