title: Transcutaneous Bilirubin Nomogram for Healthy Term and Late Preterm Neonates in First 96 Hours of Life.
abstract: BACKGROUND
  To develop nomogram of Transcutaneous Bilirubin among healthy term and late-preterm neonates during first 96 hours of age.
  
  
  METHODS
  Longitudinal observational study.
  
  
  METHODS
  Neonatal unit of a tertiary care Hospital of Central Gujarat, India.
  
  
  METHODS
  1075 healthy term and late preterm neonates (≥35weeks).
  
  
  METHODS
  Six-hourly transcutaneous bilirubin was obtained from birth to 96 hour of life using Drager JM 103 Transcutaneous Bilirubinometer.
  
  
  METHODS
  Main outcome measures: Nomogram of Transcutaneous Bilirubin with percentile values was obtained, rate of rise of bilirubin was calculated and predictive ability of normative data was analyzed for subsequent need of phototherapy.
  
  
  RESULTS
  The age-specific percentile curves and nomogram were developed from the transcutaneous bilirubin readings of 1,010 neonates. Rate of rise in first 12 hour was 0.2 mg/dL and was 0.17 mg/dL in 12 to 24 hour of life which decreased on second day of life. Neonates who required phototherapy had consistently higher readings of transcutaneous bilirubin and also higher rate of rise in first 48 hrs.
  
  
  CONCLUSIONS
  Neonates whose transcutaneous bilirubin is above the 50th percentile should be monitored for the development of significant hyperbilirubinemia.
