Transcutaneous bilirubinometry. I. Correlations in term infants

Area of Science:

• Neonatal Medicine
• Medical Devices
• Pediatricaundice

Background:

• Neonatal jaundice is a common condition requiring monitoring.
• Transcutaneous bilirubinometry offers a non-invasive method for jaundice assessment.

Purpose of the Study:

• To evaluate the accuracy and reproducibility of the transcutaneous bilirubinometer (TcB) in diverse infant populations.
• To determine the impact of phototherapy on TcB measurements.

Main Methods:

• Evaluated TcB in 43 white and 8 black infants without phototherapy.
• Assessed TcB reproducibility over 5 and 100 repetitions.
• Included 9 white infants undergoing phototherapy.

Main Results:

• High correlation (0.90) between TcB index and serum bilirubin in non-phototherapy infants.
• Phototherapy significantly decreased TcB accuracy.
• TcB demonstrated good reproducibility in healthy infants.

Conclusions:

• Transcutaneous bilirubinometry is a valuable screening tool for hyperbilirubinemia in healthy term infants.
• TcB is not recommended for monitoring infants receiving phototherapy due to reduced accuracy.
