Clinical Trial Summary

Can transcutaneous bilirubin (TcB) measurements be utilised to assess rebound hyperbilirubinaemia following phototherapy in neonates?


Clinical Trial Description

Jaundice is common in the newborn and may result in the need for babies to be readmitted from home for phototherapy, with associated increased costs and significant family distress. As well as prolonged hospital stay, neonates on phototherapy require multiple blood tests (SBR), generally acquired via heel prick testing. These cause the baby discomfort and samples may be insufficient or haemolyzed and require repeating. There is also a delay of one to two hours at best in results being received and actioned. Jaundice measurements can also be obtained using non-invasive, cheap and reliable meters (TcB) that give almost immediate results. The meter takes one to two minutes to get a result and can be used at the cotside. TcB causes the baby no significant discomfort. TcB meters are commonly used before phototherapy but are not routinely used during or after stopping phototherapy. Jaundice commonly worsens after stopping phototherapy due to release of bilirubin from tissues and so measuring a "rebound" SBR twelve hours after stopping phototherapy and before the baby can go home is routine practice. TcB meters tend to underestimate SBR in the first eight hours after stopping phototherapy but there is some evidence that thereafter they may provide reliable results. If TcB measurements can be used as a reliable predictor for SBR twelve hours after phototherapy, this will reduce blood sampling and costs, causing less distress to the baby and their mother, with potential for earlier discharge home. The NICE guideline for neonatal jaundice suggests that new research is needed to evaluate the accuracy of different transcutaneous bilirubinometers in comparison to serum bilirubin levels in all babies. ;
