Transcutaneous bilirubinometry: variability of TcB measurements on the forehead with crying.
Acta Paediatr Jpn, 1991 Oct, 33:5, 655-7
We studied the effect of crying and facial expression on TcB readings at the forehead in 38 high-risk full-term newborn infants. Our study showed that crying and facial expression were significant factors affecting the TcB readings at the forehead. We recommend that TcB readings at the forehead should be obtained in a quiet condition.
