Abstract

Background: The objective assessment of the severity of neonatal jaundice is Total Serum Bilirubin (TSB) determination, which requires multiple blood sampling. This has inherent problems, including risks of anaemia and infection. Transcutaneous Bilirubinometry (TcB) is a reliable, non-invasive alternative, however there is paucity of data on its performance in black preterm neonates.
Objectives: To evaluate the correlation between transcutaneous bilirubin (TcB) and total serum bilirubin (TSB) among Nigerian preterm neonates, and to determine the parameters affecting the relationship.
Method: Jaundiced preterm neonates delivered between 28 and 36 weeks of gestation admitted at the Irrua Specialist Teaching Hospital (ISTH), Nigeria were recruited . The TSB levels were determined by spectrophotometry while the corresponding TcB levels were obtained using Jaundice Meter (JM-103). The neonates were stratified into gestational age and birth weight groups.
Results: A total of 189 paired TcB and TSB levels were obtained from 60 neonates. The Mean (sd) TcB level of 11.4 (3.1) mg/dl was significantly higher than the mean TSB level of 10.2 (2.8)mg/dl (p= 0.028). The overall correlation coefficient between TcB and TSB was 0.98 and it was not significantly affected by the gestational age, birth weight and bilirubin levels.
Conc lusion: Transcutneous bilirubin strongly correlates with total serum bilirubin levels among Nigerian preterm neonates, irrespective of gestational age, birth weight and the degree of jaundice.
