Antenatal preparation classes offer essential resources for approaching this experience and the first days with your baby. They include exercises for managing pain and explanations of childbirth from a physiological perspective. The co-parent is also invited to certain sessions to support the mother-to-be.
Vaginal birth with medical intervention (forceps, ventouse)
During a vaginal birth, the medical team may need to use instruments. Instrumental delivery is considered by the obstetrician when labour has been ongoing for many hours without progressing, but also to prevent exhaustion in the mother-to-be and foetal or maternal distress. In France, approximately 12% of births require instrumental intervention via the vaginal route (7).
By definition, instrumental delivery is therefore "the assistance of a baby's birth through the natural passages using an appropriate instrument, in response to an unexpected and more or less urgent situation, requiring the patient's active participation following informed consent” (7).
The decision to perform an instrumental delivery is made at the end of labour and as an urgent measure, during the pushing stage, and is generally carried out under epidural anaesthesia. Certain conditions must be met before resorting to instrumental delivery: the waters must have broken, the cervix must be fully dilated (open to 10 cm), and the baby's head must be engaged. Three instruments may be used: forceps (a grasping instrument), spatulas (a propulsion instrument), and the obstetric ventouse (a traction instrument). The choice of instrument depends on the obstetric situation, and only the obstetrician present can make this decision at the moment the indication arises.
Foetal or maternal complications are rare, and instrumental delivery does not in itself increase the rate of episiotomy. The risk of vaginal, perineal, or anal sphincter tears is increased, linked to the use of forceps or spatulas, but is also related to the presentation, the baby's size, and the indication for delivery. The obstetrician present will decide at the time whether an episiotomy is necessary to protect the maternal perineum.
Once an instrumental vaginal birth is complete, pain is managed by the medical team. The postnatal recovery period will be longer if there has been a tear or an episiotomy. Some professionals recommend booking a few osteopathy sessions to reposition the pelvic bones.
Vaginal birth after caesarean: what do the studies say?
The belief that having a caesarean section necessarily means having one every time afterwards is no longer current thinking (8)! If the reasons for your previous caesarean are not related to an irreversible anatomical issue, there is no reason not to attempt a vaginal birth. Recommended by the French National Authority for Health, today more than one third of women give birth vaginally after a caesarean (9)!
The success of a vaginal birth after caesarean (VBAC) depends above all on the reasons that led to the first caesarean and on how the current pregnancy has progressed. Several factors are associated with successful VBAC: a maternal age under 40, a normal body mass index, a gestational age under 40 weeks, and a gap of at least 2 years between births.
To minimise complications during childbirth, there are contraindications to vaginal birth after caesarean. A previous high vertical uterine incision, placenta praevia, multiple pregnancy, a history of caesarean sections, or a previous uterine rupture are risk factors that your doctor will take into account (10). Whilst VBAC is not recommended if the mother has a history of uterine rupture (11), the risk of uterine rupture following a VBAC remains low, at under 0.5% (12,13).
The use of epidural anaesthesia during a VBAC is subject to debate — whilst it offers the significant benefit of pain relief, the oxytocin injection required to restart labour increases the risk of uterine rupture. It may be possible togiving birth without an epidural.
Ultimately, choosing between VBAC and a repeat caesarean is not straightforward. The decision on the method of birth following a previous caesarean should be discussed in consultation with a doctor, taking into account each mother's individual circumstances.
