Background: There are limited data about the proper transcutaneous bilirubin measuring time to detect levels that are close to serum bilirubin levels after ending the phototherapy treatment. Objectives: To compare the transcutaneous bilirubin and total serum bilirubin levels, and to evaluate the reliability of transcutaneous bilirubin measurements after phototherapy treatment of newborns because of hyperbilirubinemia. Methods: The study included 105 late preterm and term newborns consisting of 56 females (53.3%) and 49 males (46.6%), with gestational age 350/7 - 416/7 weeks who were treated with phototherapy. A Bilicheck (M&B-MBJ20) device was used for transcutaneous bilirubin measurements. The average of three measurements on the skin in the mid-sternal area were obtained. Correlations between transcutaneous bilirubin and venous bilirubin levels were evaluated 6 and 12 hours after phototherapy. Transcutaneous bilirubin measurements were performed simultaneously with blood collection or within a maximum ± 15 minutes time difference for total serum bilirubin. Results: The average phototherapy time was 10 ± 2 (range, 8 - 12) hours. The average difference between transcutaneous bilirubin and venous bilirubin levels post phototherapy was 2.61 mg/dL after 6 hours and 0.8 mg/dL after 12 hours. The hematocrit levels of the patients ranged between 40 - 66% with an average of 53% ± 4.8, the median level was 51%. Correlation coefficients according to hours after treatment were high for the 6th hour (r = 0.76) and very high for the 12th hour. Conclusions: Jaundice scanning with transcutaneous bilirubin measurements 6 - 12 hours after the end of phototherapy is reliable and may be helpful in preventing additional blood collection from the heel.

Background The gold standard for diagnosis of neonatal jaundice is total serum bilirubin (TSB) measurement. This method, however, is invasive, painful, and costly in terms of workload, time, and money. Moreover, repeated blood sampling may lead to significant blood loss, which is of particular concern in preterm infants. To overcome these drawbacks, non-invasive methods of bilirubin measurement have been proposed. Transcutaneous bilirubinometry (TcB) determines the yellowness of the subcutaneous tissue of a newborn infant by measuring the difference between optical densities for light in the blue and green wavelength regions.Objective To evaluate the accuracy of transcutaneous bilirubinometry for estimating TSB levels in neonatal jaundice.Methods Subjects were infants aged < 28 days with jaundice who had never been treated with phototherapy or exchange transfusion. The study was done from February to July 2016 in Mohammad Hoesin Hospital. Subjects underwent transcutaneous bilirubin (TcB) and TSB assays, with a maximum interval of 15 minutes between tests.Results One hundred fifty patients were included in this study. The TcB values > 5 mg/dL were correlated to TSB > 5 mg/dL, with 100% sensitivity and 83.3% specificity. This cut-off point was obtained from a receiver-operator characteristic (ROC) curve with AUC 99.3% (95%CI 97.9 to 100%; P< 0.001).The correlation coefficients (r) for TSB and TcB measurements on the forehead were 0.897 (P<0.001).Conclusion Transcutaneous bilirubinometry can be used to accurately estimate TSB levels in neonatal jaundice, and may be useful in clinical practice as a non-invasive method to reduce blood sampling.

The accuracy of transcutaneous bilirubin meters has been assessed in newborns from various ethnic backgrounds. However, there are limited data on Greek newborns. Our study examined the accuracy of transcutaneous bilirubin measurements in clinically jaundiced healthy-term Greek newborns, using total serum bilirubin as the reference standard, in order to re-evaluate our local guidelines about neonatal jaundice. Clinically jaundiced newborns requiring total serum bilirubin level estimation were recruited prospectively. 368 pairs of total serum bilirubin/transcutaneous bilirubin measurements were taken in 222 newborns, using a direct spectrophotometric device and the BiliCheck device, respectively. The level of agreement between the obtained transcutaneous bilirubin and total serum bilirubin values was assessed. Our data were analysed using the Stata/SE 12.0 (StataCorp LP, USA) statistical programme. The mean (± SD) TSB was 225.4 ± 25.4 μmol/l and the mean (± SD) TcB was 237.9 ± 21.0 μmol/l. The correlation between the values was poor (Pearson’s correlation coefficient 0.439; Lin’s concordance coefficient 0.377 [95% CI 0.301 to 0.453]; P<0.001). The Bland-Altman analysis demonstrated that transcutaneous bilirubin measurements tended to overestimate the total serum bilirubin value (mean difference 12.5 ± 24.9 μmol/l), with wide 95% limits of agreement (–36.2 μmol/l to 61.3 μmol/l). Transcutaneous bilirubin values did not correlate well with total serum bilirubin values, being often imprecise in predicting the actual total serum bilirubin levels. This permits us to continue estimating total serum bilirubin in clinically jaundiced newborns according to our local guidelines, in order to safely decide the appropriate care plan.

Background Although phototherapy has been used in clinical practice for 40 years, there is still much debate on how to provide the most efficacious phototherapy. Phototherapy with white reflecting curtains may increase the average spectral irradiance provided, as well as decrease serum bilirubin concentrations at a faster rate in neonates with jaundice.Objective To determine if adding low cost, white, reflecting curtains to a standard phototherapy unit can increase the effectiveness of phototherapy for neonatal jaundice.Methods A randomized, controlled, open trial was conducted at H. Adam Malik and Pirngadi Hospitals, Medan, from May to December 2009. The criteria for inclusion in the study were full term newborns with neonatal jaundice presenting in their first week of life. Single phototherapy with white curtains hanging from the sides of the phototherapy unit (study group, n=30) was compared to single phototherapy without curtains (control group, n=30). The primary outcomes measured were the mean difference in total serum bilirubin levels and average spectral irradiation levels measured at baseline, and after 12 hours and 24 hours of phototherapy.Results The sum of average spectral irradiance in the curtained phototherapy unit was significantly higher than that of the standard phototherapy unit without curtains (P < 0.05). The decrease of total serum bilirubin levels after 12 and 24 hours of phototherapy was significantly greater in the study group (3.71 and 9.7 mg/dl, respectively) than in the control group (0.1 and 3.8 mg/dl, respectively), both P <0.05.Conclusion White, reflecting curtains in phototherapy units was significantly more effective than phototherapy without curtains for treatment of neonatal jaundice.

Background: Hyperbilirubinemia is a common problem in newborn. Most of the cases are benign but severe hyperbilirubinemia can lead to kernicterus and brain damage which is preventable. The gold standard to asses neonatal hyperbilirubinaemia is serum bilirubin measurement. Unfortunately, this procedure is invasive, painful and time consuming. As the consequence of missing severe hyperbilirubinemia is serious, there is a constant search to find out a safe method to detect jaundice. Transcutaneous bilirubinometry offers objective method of assessing degree of jaundice reducing subjectivity of clinical assessment.Objective: To evaluate the relationship between transcutaneous bilirubin (TcB) and total serum bilirubin (TSB) and assess whether transcutaneous bilirubinometry can be used as a valid screening method for detecting jaundice in term and late preterm babies.Method: A prospective cross-sectional study was performed in well baby nursery of United Hospital Limited, Dhaka from January 2013 to December 2013. Healthy term and late pre term newborn of ?35 wk gestation with clinical evidence of jaundice were included in the study. Total serum bilirubin was measured by Dichlorophenyl Diazonin method and transcutaneous bilirubinometer (JM-103) was used to measure transcutaneous bilirubin (TcB) level.Result: A total of 116 paired samples were analyzed and found strong correlation between TcB and TSB (correlation coefficient 0.8, mean difference 0.83, SD± 1.96 and 95% CI 0.6 to 1.06). Post natal age has significant association with TcB (p value 0.01) and TSB (p value 0.031). Requirement of phototherapy in both group were also significant (p value <0.001). TcB value of 11 mg/dl was chosen as cut off point corresponding TSB level 13 mg/dl with sensitivity 90% and specificity 71%. Above this level indicate need for blood sampling to take appropriate therapeutic measure.Conclusion: Transcutaneous billirubinometry is a non-invasive and valid screening tool for assessing jaundice in newborn.Bangladesh J Child Health 2015; VOL 39 (3) :116-122

Objective. To determine whether transcutaneous bilirubin measurements (TcB) before and during phototherapy taken from covered skin during phototherapy correlate with total serum bilirubin (TSB) levels.Study Design. In this prospective observational study, healthy term newborns who required TSB measurements were included. TcB measurements were taken from the forehead before starting and during phototherapy using the BiliChek device. Before starting phototherapy, part of the forehead was covered. Blood for TSB measurement was collected within 5 minutes of TcB measurements. Correlations and mean differences between TcB and TSB before and during phototherapy were calculated.Result. Paired TSB and TcB measurements before and during phototherapy in 151 newborns were performed. The mean gestational age was 38.8 weeks and birth weight was 3.1 kg; 53% were male. Before starting phototherapy, TSB and TcB were183.8±41.6and 190.5 ± 43 μmol/l, respectively. During phototherapy, TSB and TcB were191.8±39.4and187.8±45.3 μmol/l, respectively. Linear regression analysis showed a significant correlation between TcB and TSB before starting phototherapy and during phototherapy (r: 0.85;p<0.001andr: 80.0;p<0.001), respectively. Before starting phototherapy, the mean difference between TSB and TcB was6.2±23.2 μmol/l, with a 95% CI of −39.3 to 51.7 μmol. During phototherapy, the mean difference was −2.8±23.5 μmol/l, with a 95% CI of −48.9 to 43.3 μmol/l.Conclusion. TcB measurements from covered skin in jaundiced term infants during phototherapy correlate with TSB and can be used to monitor bilirubin levels during phototherapy.
