Vacuum extraction is a medical procedure used during childbirth to assist in delivering a baby. It involves placing a soft cup on the baby's head and using a vacuum device to create suction. This helps guide the baby out of the birth canal when labor is not progressing effectively or if the baby is in distress. The procedure is typically performed by an obstetrician or midwife and is considered when certain conditions are met, such as the mother being fully dilated. While generally safe, vacuum extraction can carry some risks, including minor injuries to the baby or mother.
