• An improved method for placement of endotracheal tubes was investigated. A fiberoptic guide is used that transilluminates from within the tube's lumen, permitting one to relate the tube's position to skeletal landmarks. The procedure is safe and was 100% successful in 20 infants in whom the instrument was tried.
