Rapid detection of neonatal intracranial hemorrhage by transillumination.
Using transillumination and a sensitive cadmium sulfide light meter, 145 newborns were screened for the presence of intracranial hemorrhage. Intracranial hemorrhage (ICH) was suspected when the light meter could not detect any light passing through the anterior fontanel when the light beam was directed through the frontal eminence. ICH was confirmed by branial computed tomography or postmortem examination in all 17 infants not transmitting light. Spectrophotometry was performed on samples of cerebrospinal fluid (CSF) to demonstrate the mechanism through which blood in the CSF blocks light transmission.
