A GESTATIONAL AGE RELATED STUDY OF LENGTH AND DIAMETER OF UMBILICAL CORD AND THEIR CORRELATION WITH BIRTH WEIGHT

Abstract
The umbilical cord connects the fetus to the placenta for gaseous exchange, waste elimination and nutrient uptake. The umbilical cord along with the placenta is disposed off as medical waste after birth. But, the umbilical cord can prove to be a marker of certain adverse prenatal conditions. A short cord may cause traction during delivery, placental abruptions, uterine inversion or cord herniations. Abnormally long cord may lead to conditions like true knots, cord prolapse and coiling of the cord around fetal parts. Thin cords are found to be associated with intrauterine growth retardation (IUGR), small for gestational age babies (SGA) and low birth weight (LBW). The present study of 500 umbilical cords recorded the length and diameter of umbilical cords and their relationship with gestational age group and birth weight. Important variations in umbilical cord length and diameter were observed in the study. The length of the umbilical cords was found to have a range of 32.50 to 76 cm with a mean of 54.66 ± 7.09 cm. The umbilical cord diameter had a range of 0.8 cm to 1.60 cm with an average of 1.23 ± 0.19 cm. There was no significant difference found either in the mean cord length or mean cord diameter among different gestational age groups. Umbilical cord length was found to have a significant positive correlation with birth weight. However, the study did not find statistically significant correlation between cord diameter and birth weight.
