ABSTRACT
Objective: To correlate umbilical coiling index (UCI) and perinatal outcome. Material & methods: Present prospective study was conducted on 582 antenatal mothers in second trimester with singleton live pregnancy in Kamineni Institute of Medical Sciences, Nalgonda. During growth scan UCI was measured. UCI between 10th - 90th percentile was considered as normocoiled, less than 10th percentile as hypocoiled and more than 90th percentile as hypercoiled. Then UCI was correlated with maternal and neonatal outcome. Results: Mean UCI was 0.24 ± 0.78 coils per cms. Maximum were normocoiled in 59 %, 22.5% were hypocoiled and 18.5% were hypercoiled. Abnormal UCI was associated with pregnancy induced hypertension, abnormal partogram, increased operative delivery, low APGAR scores, more NICU admissions and low birth weight which were statistically significant (p value <0.05). Conclusion: Abnormal UCI is associated with adverse perinatal outcome. Therefore it is good tool for identifying fetus at risk and thereby improving perinatal outcome by appropriate intervention. As it is done during growth scan, there will be no additional economical burden to patient.
