Transcutaneous Jaundice Meter Pay Attention to Project of Healthy Pregnancy and Scientific Nurture Hyperbilirubinemia is a common condition in newborn infants and may cause kernicterus if not properly managed. Therefore, jaundice in the newborn should be dynamically observed so as to diagnose and treat timely. However, repeated blood sampling for measuring sérum bilirubin is painful and is a cause for distress to the infant, increases the workload of the nursery staff, and not readily accepted by parents. KJ-8000 transcutaneous jaundice meter is first produced in China, It utilizes fiber, photoelectric, electronic and information processing technologies. It is small and light. You just press the probe lightly on the forehead of the baby and the bilirubin concentration in the skin tissue is immediately Application Scope ' A TcO -av be hjMUjassl lof NJli Ncar cxJwlenli a Hilti i% caefe-ed NKH - Nfin'uital wnn hi aubin TcB - Ifanuiitannou* tu ai**» KJ-8000 transcutaneous jaundice meter is widely used in newborn nursery, newborn outpatient clinic, newborn intensive care unit (NICU),children health care department, etc. Diagnostic Criteria of Pathological Jaundice (For référence only. Spécifie ciagnoses is made by doctors according to clinical conditions) Pathological jaundice occurs in terni infants if sérum bilirubin concentration at 24 hours after birth is higher than 6mg/dl, sérum bilirubin concentration at 24-48 hours is higher than 9mg/dl, sérum bilirubin concentration at more than 48 hours is higher than 12.9mg/dl. Jaundice is more serious at lewer bilirubin levels in preterm infants. Sérum conjugated bilirubin concentration is higher than 34umol/l Sérum bilirubin increases more than 8bumol/l (bmg/dl) every day. Jaundice duration is long, mo'e than 2-4 weeks, or becomes more serious. Occurs late but is incurable, or rises again after régression. The gold standard for measuring bilirubin is high performance liquid chromatography (HPLC). However it requires expensive equipment and is available in a few centers. According to a study by the University of Michigan in the USA, transcutaneous bilirubin (TcB) has similar, if not better. sensitivity and specificity as total sérum bilirubin (TSB) when Because most newborn babies are being discharged early, jaundice may not appear until they are at home. For this reason, many hospitals in developed countries have adopted TcB as a routine measurement prior to discharge from the newborn nursery and plotting the resuit on the bilirubin nomogram. Such practice has saved many babies from complications of hyperbilirubinemia. Researchers at the University of Pennsylvania in the US, following adopting routine pre-discharge TcB, concluded: "Our data demonstrate the accuracy and reproducibility of the predischarge TcB measurements in term and near-term newborn infants of diverse races and ethnicities. Infants with predischarge TcB values above the 75th percentile of hour-specific TSB values on the bilirubin nomogram may be considered to be at high risk for subséquent excessive A similar study at the University of Florence Médical School in Italy had a similar conclusion: "Transcutaneous bilirubin detector" could be used not only as a screening device but also as a reliable substitute of total sérum bilirubin (TSB) détermination. At higher levels of TSB, in which phototherapy and/or exchange transfusion might be considered, TcB performed slightly better than the laboratory^. " Measurement of bilirubin with "transcutaneous technique" is rapid and simple, and it is easy to perform repeated measurements over time, thus reducing the likelihood of error. TcB measurements with the jaundice meter should obviate the need for most sérum bilirubin levels in newborn infants > or =35 weeks of gestation, although sérum bilirubin measurements are still required when treatment with phototherapy or exchange transfusion is being considered4." A French study also concluded that transcutaneous bilirubin (TcB) "may be used to monitor bilirubin in term neonates at 48 hours of life even with a weight loss. Clinidans have however to be conscious of the limit of the précision of the measures both for theTcB and the laboratory methods (TSB) 5." 1. University of Michigan Health System.
