Abstract
-
The umbilical cord length may be a reliable indicator of fetal activity during gestation because it grows in response to tensile forces related to fetal movement. But there has been little attention to normal range of the umbilical cord length. We analyzed the umbilical cord length of 2342 cases de1ivered in Seoul National University Hospital to determine mean values according to the gestational age. The umbilical cord length increased linearly from 15.5cm of 13 week to 50.6 cm of 44 week. After 42 week, the growth was nearly stopped. There was no difference by fetal sex. The length of umbilical cord was variable even within same gestational age.
