The ventouse method is a commonly used intervention in assisted vaginal birth. The ventouse is a vacuum extraction instrument that applies traction. It can be used as an alternative to forceps. The cup clings to the fetal scalp by suction and is used to assist maternal effort. It may be used when there is a delay in labour, when the cervix is not quite fully dilated. It may also be useful in the case of a second twin, when the head remains relatively high.
Prolonged traction will increase the likelihood of scalp abrasions, cephalhaematoma and subaponeurotic bleeding.
