EV pregnancy refers to a pregnancy where External Cephalic Version (ECV) is considered or performed. External Cephalic Version (often abbreviated as ECV or EV) is a procedure used to manually turn a baby from a breech position (feet or buttocks first) to a head-down position in the uterus before labor begins.
Here's a breakdown:
-
Breech Presentation: A breech presentation occurs when the baby is positioned in the uterus with their buttocks or feet facing the birth canal instead of their head.
-
External Cephalic Version (ECV): ECV is a manual procedure where a healthcare provider applies pressure on the mother's abdomen to encourage the baby to turn to a head-down (cephalic) position. This is usually attempted after 36 weeks of gestation.
-
EV Pregnancy Context: The term "EV pregnancy" isn't a formal medical term. Instead, it describes a pregnancy where the baby is breech, and ECV is a considered or attempted management strategy. Ideally, a head-down position is preferred for vaginal delivery.
Why is ECV performed?
The goal of ECV is to increase the chances of a vaginal delivery. Vaginal delivery is generally considered safer for both the mother and baby than a Cesarean section (C-section), but only when the baby is in the cephalic or head-down position.
What happens during an ECV procedure?
- Preparation: The mother will be monitored, and an ultrasound will be performed to confirm the baby's position, assess the amount of amniotic fluid, and check the baby's well-being.
- Medication: Sometimes, a medication called a tocolytic is given to relax the uterus.
- Procedure: The healthcare provider will use their hands to gently guide the baby into a head-down position by applying pressure to the abdomen.
- Monitoring: The baby's heart rate will be monitored throughout the procedure.
Is ECV always successful?
No, ECV is not always successful. The success rate varies, but it is often around 50-70%. Factors that can influence the success of ECV include the baby's position, the amount of amniotic fluid, whether the woman has had previous pregnancies, and the skill of the healthcare provider.
Risks of ECV:
While generally safe, ECV does carry some risks, including:
- Premature labor
- Placental abruption (separation of the placenta from the uterine wall)
- Uterine rupture (rare)
- Fetal distress
Alternatives to ECV:
If ECV is unsuccessful or not recommended, a Cesarean section may be planned.
