Vacuum extraction (VE), also known as ventouse, is a method to assist delivery of a baby using a vacuum device. It is used in the second stage of labor if it has not progressed adequately. It may be 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.
[3] [27] There have also been developed practices to minimize the impact of vacuum-assisted delivery on the neonatal head. Such a method is to use a proper vacuum cup to apply pressure up to 0.8 kg/cm 2 and rhythmically sync the vacuum with uterine contractions in order to both expedite the delivery process and minimize traction-induced scalpel ...
Operative vaginal delivery, also known as assisted or instrumental vaginal delivery, is a vaginal delivery that is assisted by the use of forceps or a vacuum extractor. [ 1 ] Operative vaginal delivery is required in times of maternal or fetal distress to assist in childbirth as an alternative to caesarean section . [ 2 ]
The first model of the device was created by sewing a sleeve onto a cloth bag and was tested using a doll inserted into a glass jar to simulate the use of the device in the delivery process. [1] In complicated deliveries, the device is positioned against the baby's scalp and the lubricated sleeve is gently inserted around the baby's head.
Use the middle finger to identify the posterior fontanelle, then move the finger forward along the sagittal suture approximately 3 cm / 1 inch.; With the finger on the flexion point and palmar surface in a superior direction, note where the back of the finger makes contact with the fourchette (this is used to determine how far the ventouse cup must be inserted).
However, a skilled midwife or obstetrician a complication-free vaginal birth may be achievable through movement and positioning of the mother, and patience and allowing the baby to move through the pelvis and moulding of the skull during the birthing process. Other options include the use of vacuum-assisted delivery and forceps.

Low forceps delivery, when the baby's head is at +2 station or lower. There is no restriction on rotation for this type of delivery. Midforceps delivery, when the baby's head is above +2 station. There must be head engagement before it can be carried out. High forceps delivery is not performed in modern obstetrics practice. It would be a ...
