Comparative Study Serum and Cutaneous Total Bilirubin among Newborns with Hyperbilirubinemia in Khartoum State

الملخص

The standard methods used in measuring serum bilirubin require blood specimens taken by heel pricks or intravenous blood sampling but transcutanse bilirubin is a new method for measuring bilirubin in neonate. So this study was conducted to compare the estimates of serum bilirubin using a recently introduced device called (MBJ20), which is TransCutaneous Bilirubinometer (TCB) index with the standard direct spectrophotometric measurement of Total Serum Bilirubin (TSB). This cross-sectional study was conducted in neonatal intensive care unit at Soba University Hospital, where one hundred and fifty three, newborns with hyperbilibrubina were enrolled. Both TSB and, TCB readings were evaluated.

According to the date of jaundice onset 91.9% developed jaundice during period of 2-7 days; 5.9% in the first day and 2.6% after a week. TSB level among jaundiced neonates less than 12 mg/dL was found in (29.4%), 12 – 2 mg/dL were detected in (67.9%), and More than 20 mg/dL was recorded in (2.6%). On the other hand TCB level was less than 12 mg/dL found in (20.9%), 12 – 2 mg/dL was detected in (77.1%) and more than 20 mg/dL cited for (1.9%). At P≤0.05 there were no significant differences in TSB and TCB before phototherapy with Mean (13.40±2.83, 13.49±3.00) mg/dL for TSB and TCB respectively (P value .539). And after photo therapy Mean of TSB and TCB index were (13.00 ±4.40, 13.06±2.57) mg/dL respectively (P value 0.769). Neonatal birth weight showed extremely low birth (2.6%), low birth weight in (54.9%), normal weight (37.3%) and Macrosomic (5.2%). The Gestational age of jaundiced neonates showed pre-term (48.4%), term (49%) and Post-term (2.6%). The study revealed that TCB was an accurate method, as TSB before and after phototherapy. No difference when TCB was used for measuring TSB in term or preterm babies. So TCB device could be used in every Nursery as reliable.
