What is transcutaneous Bilirubinometry?
Transcutaneous bilirubin (TcB) measurement is a non‐invasive method for measuring serum bilirubin level (Dai 1997). Transcutaneous bilirubinometry works by directing light into the skin and measuring the intensity of the wavelength of light that is returned (Boo 2007).
How much does a transcutaneous Bilirubinometer cost?
There are two types of transcutaneous bilirubinometers (JM and BiliCheck meter) that are commonly used for estimation of serum bilirubin in neonates. The direct cost for the JM meter costs about US$3995 and requires no additional supplies.
How accurate is Bilirubinometer?
The accuracy of using TcB values to detect neonates who required phototherapy was 92.5%. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 78.3, 94.2, 62.1, and 97.3%, respectively.
What is a BiliCheck?
The Bilicheck®, a new transcutaneous bilirubinometer, is considered as a more accurate measurement of bilirubin compared to the previous bilirubinometers courtesy of its advanced technology.
What level bilirubin causes brain damage?
Kernicterus, or bilirubin encephalopathy, is bilirubin-induced neurological damage, which is most commonly seen in infants. It occurs when the unconjugated bilirubin (indirect bilirubin) levels cross 25 mg/dL in the blood from any event leading to decreased elimination and increased production of bilirubin.
How does Bilirubinometer work?
High correlation between cutaneous bilirubin and TSB form the basis of Transcutaneous Bilirubinometry. These meters work by directing light into the skin of the neonate and measuring the intensity of specific wavelength that is returned. These are analyzed by a microprocessor to generate a serum bilirubin value.
How does a Bilirubinometer work?
How do you use a Bili meter?
Place the Bili-meter’s sensor head on the infant’s abdomen (if supine) or back (if prone) and aim toward the center of the phototherapy light. Press the “READ” button and record reading in microwatts per square centimeter per nanometer. For example, if the display reads 7, the reading is recorded as 7 µw/cm2/nm.
What is transcutaneous bilirubinometry and how does it work?
High degree of correlation between cutaneous bilirubin and TSB is the basis of transcutaneous bilirubinometry. Simply stated, transcutaneous bilirubinometer measures the yellowness of the skin by analyzing the spectrum of light reflected by the baby’s skin.
What is the best bilirubin meter?
Currently there are two transcutaneous bilirubin meters that have been validated through extensive study, 5–7 BiliChek (Philips Respironics) and the Drager Jaundice Meter JM-103 (Drager Medical). The devices work by transmitting a light source into the skin of the subject and measuring the reflected light.
How do you measure bilirubin levels in phototherapy?
Transcutaneous bilirubin measurements can only be used to monitor efficacy of phototherapy when the Medela Bilibed � (Fischer & Paykel) is in use. This method of phototherapy does not expose the forehead to therapeutic light. Take two single TcB readings � if there is a difference in readings of less than � 60�mol/L document the higher reading.
What is the history of bilirubin measurement?
In 1980, Yamanouchi et al 4 and the Minolta Camera Company developed one of the first clinically applicable transcutaneous bilirubin meters. Since then, there have been numerous technological advances that have led to improved accuracy and reliability when assessing jaundice with TcB.
