An umbilical cord clamp may be used to hold the cord in place when a cut is made to separate a newborn baby from the placenta.his procedure usually first involves clamping the cord. The umbilical cord clamp thus refers to the devices used to hold the cord in place when the cut is made, and the clamp may stay on for several days while the remaining cord attached to the baby dries.
The clamp can be removed when the cord is completely dry. The cord falls off by itself in about two to three weeks. Because the umbilical cord may be a place for infection to enter the baby's body, it is important to care for it properly.ithin a few minutes after birth, the cord is clamped and cut close to the navel. The clamp helps stop bleeding from the three blood vessels in the umbilical cord--two arteries and one vein. A medication is sometimes applied to the cord as part of a baby's first care.
