[A practicable method of polygraphic investigations in preterm and fullterm neonates (author's transl)].

Polygraphic recording techniques (simultaneous recording of several physiological variables) have been used earlier in investigations of normal newborn and preterm infants. The clinical value of prolonged polygraphic recordings in highrisk neonates is well-known. The main-purpose of this paper is to demonstrate a clinically practicable method of polygraphic recording technique, needing no more than two hours recording-time and its interpretation by means of visual analysis.
