How long does it take for the umbilical cord to fall off in premature infants?

The umbilical cord of a premature infant usually falls off about one week after birth, although the exact timing may vary.

In most cases, the umbilical cord of a premature infant naturally falls off around one week after birth. This is a common occurrence. After birth, the umbilical cord of most premature infants begins to gradually dry up and shrivel, completing the detachment process within approximately one week. This timeframe is generally similar to that of full-term infants, reflecting the common pattern of umbilical cord separation in newborns. While most premature infants' umbilical cords fall off within about a week, there are also some cases where a longer duration may be required.

Keeping the umbilical area clean and dry is fundamental and one of the most important steps. Gently wipe the umbilical stump and surrounding skin daily with 75% alcohol to ensure the area remains dry, which helps the umbilical stump dry up and fall off more quickly. Apart from necessary cleaning, touching the umbilical cord should be minimized, and other products should be avoided to prevent infection or delayed healing. Each infant's umbilical cord detachment time varies, and premature infants may take longer. Parents should be patient and avoid taking improper measures out of concern.

Parents should closely monitor the umbilical cord condition of premature infants to ensure it separates smoothly within the expected timeframe.
