Flexible neonatalscope.

Since the introduction of small flexible fiberoptic scopes for the examination of airways, efforts have been made to reduce their size to fit the smallest patients. The first practical scope of this type was the 3.9-mm nasopharyngolaryngoscope introduced in 1975. Modifications over the years have led to the development of the 1.7-mm neonatalscope, primarily designed for the examination of intubated neonates. This neonatalscope has been of great help in determining placement of endotracheal and tracheotomy tubes, as well as in localizing areas of obstruction within the tubes. By means of a special adapter the scope may be used while the patient is on a respirator. Introduction of this new generation of flexible scopes will undoubtedly lead to other valuable and interesting applications of this instrument.
