When the vacuum is applied to the infant's head, the tension creates a difference in pressure between the atmosphere and the infant's scalp that causes the soft tissue layers of the scalp to fill inside the suction cup. [5] [6] Subsequently, interstitial fluid and small hemorrhages build up, causing the head to swell and forming a localized edema.
Caput succedaneum is a benign neonatal condition involving a serosanguinous (containing blood and serum), subcutaneous, extra-periosteal fluid collection with poorly defined margins caused by the pressure on the presenting part of the fetal scalp by the vaginal walls and uterus as the infant passes through a narrowed cervix during delivery.
