[Selection of location for transcutaneous bilirubinometry in light therapy]

64 jaundiced neonates were measured with transcutaneous bilirubinometer for the jaundice index on the forehead and superciliary narch where was covered during photo therapy respectively. The result showed that the jaundice index in the uncovered place decreased greatly after the therapy was over, but the index went up again 12 hours later. The index on the covered place did not show this change. It is suggested that the covered place is a better site for measuring jaundice index because it can avoid the effect of phototherapy on the measuring result and make the result more accurate.
