Popis: | 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. |
