OBJECTIVE: To create a nomogram based on transcutaneous bilirubin values (TCB) in first week of life for term and late preterm (>34 weeks) neonates.
METHODS AND DESIGN: Prospective longitudinal study.
SETTING: Four tertiary-care teaching hospitals (one each in eastern and southern India, two in northern India) between February 2019 and March 2020.
PARTICIPANTS: A total of 2492 term and late preterm (>34 weeks) neonates.
INTERVENTION: Bilirubin was measured by transcutaneous bilirubinometer (Drager JM-105, Germany) in all neonates in pre-specified times of the day, 12 hourly every day since birth till discharge between 48 and 72 h, and data were recorded in epochs of 6 hourly intervals. Post-discharge, all neonates were called for review in next 48 h.
OUTCOME MEASURES: Primary-TCB in first week of life. Secondary-factors having significant association with significant hyperbilirubinaemia requiring phototherapy.
RESULTS: Total of 2492 neonates (males 1303 and female 1189), with a total of 14 162 TCB recordings were analysed and mean hourly bilirubin (TCB) at hourly intervals till 120 h and then daily bilirubin values on Days 6 and 7 were tabulated. We have constructed hour-specific bilirubin nomogram with percentiles as per gestational age in term and near-term Indian neonates till 120 h of life. Amongst the known risk factors, delayed cord clamping, primipara and breastfeeding jaundice had significant association for hyperbilirubinaemia needing phototherapy.
CONCLUSIONS: We have created gestation-specific nomogram of TCB levels in 6 hourly intervals for the first 120 postnatal hours, obtained from a large predominantly breast fed healthy, term and near-term Indian neonates.
