An episiotomy is a cut made to widen the opening of the vagina. It is done toward the end of labor to keep the vaginal tissues from tearing as the baby is born. Sometimes an episiotomy can also help the doctor to deliver the baby quickly if the baby is in distress.
Usually, the doctor or midwife attending the birth decides whether to do an episiotomy. An episiotomy may be done when:
As the crown of the baby's head pushes through the vaginal opening, an anesthetic is injected in the mother's perineum to numb it. The perineum is the skin area between the vagina and anus. A cut 2 to 3 inches long is made there. After the baby is born and the placenta is delivered, the cut is stitched up.
