Objectives: The aim of the study is to determine the association between the length of the umbilical cord and the coiling index with the perinatal outcome. Methods: It’s a prospective study of 600 pregnant women from 28 to 40 weeks of gestational age. The umbilical cord length was measured from the placental insertion point to the foetal attachment of the cord. The coiling index was calculated by dividing the number of coils divided by the length of the cord. The coiling index was measured at the time of cord clamping in both vaginal and caesarean section. The cases were divided into three groups i.e., normocoiled, hypocoiled and hypercoiled and their association with the perinatal outcomes were assessed. Results: The mean umbilical coiling index(UCI) was found to be 0.57±0.18 coils per cm. Abnormal foetal heart patterns, oligo and polyhydramnios, hypertensive disorders, placental abruption, gestational diabetes mellitus, caesarean section rates, low birth weight and intrauterine foetal death had high correlation with hypocoiled and hypercoiled compared to normocoiled which is statistically significant (p-value of <0.001) in our study. Conclusion: Abnormal umbilical coiling index which is measured during both vaginal delivery and caesarean section is associated with adverse perinatal outcomes.
