title: [Laser spectroscopy in the newborn infant--initial experiences].
abstract: Equipment for near-infrared laserspectroscopy for clinical application is newly available. By this technique noninvasive monitoring of biochemical parameters is achievable. We report on our first experience with a Radiometer prototype for such NIR laserspectroscopy during measurements in 5 neonates. Laserdiodes provide emission at a wavelength of 775, 805, 845 and 904 nm. The registered signals are computerized aiming at a calculation of relative changes of saturated and unsaturated hemoglobine, changes in blood volume and cytochrome aa-3. In this article graphical display of the parameters give insights in the redoxstate and the hemodynamics of the biological sample. The near-infrared laserspectroscopy has the potential of becoming an instrument for the study of biophysical and biochemical alterations in the newborn.
