Transillumination of the chests of neonates1 has been used in our neonatal intensive care unit now on approximately 200 neonates with pneumothorax (PT) or pneumomediastinum (PM) using the Minilight illuminator* without any deleterious effects.
Even though the fiberoptic probe tip remains cool when exposed to air indefinitely, we still wished to test for the build-up of heat beneath the rubber-sheathed probe tip of the Minilight and the Chun Gun
when these were held tightly against the skin.
