Abstract:

Goal: Yellowness is a physiological condition caused by the common hyperbilirubinemia in the newborn period. But when not followed and treated, serious hyperbilirubinemia can cause kernicterosis, a serious condition that leads to neurological problems. In our study, we aimed to investigate whether it would be safe to use the TcB measurement instead of taking blood for yellow assessment by comparing the total serum bilirubin (TSB) measurement values, which is the standard method of transcutan bilirubin (TcB) measurement. MATERIAL AND METHOD: 105 babies were taken to study with gestational ages between 37 and 42 weeks. In TcB measurement, the MBJ20 transcutaneous bilirubin measurement device was used. TcB measurement was made from the sternum and the sternum. To evaluate the relationship between TcB measurements and TSB measurements, we implemented the Bland-Altman analysis, which we assessed the differences between pearson correlation, Spearman correlation, linear regression analysis and average measurements. Results: TcB take and there was a very good level and statistically meaningful correlation in the positive direction between TSB measurements and TcB sternum and TSB measurements (p<0.001). Linear regression analysis found that there was a linear relationship between TSB measurements (R2=0.85) and TcB sternum and TSB measurements (R2=0.87) (+). TSB and TcB take measurement methods (medial difference: 0.39±1.46, 95% CI: (-2.47)-(3.26)) and between TSB and TcB sternum measurement methods (medial difference: 0.49±1.32% 95 CI: (-2.1)-(3. In Bland-Altman analysis, we found a good harmony between the two methods. As a result of our study, we found that TcB measurement can be used safely instead of taking blood for yellowness assessment. (SETB 2020-01-08)
