A Polygraphic Study of Normal and Abnormal Newborn Infants

Abstract

Twenty-three low-risk full-term newborn infants were examined with polygraphic methods on their first and fifth day of life. Twelve of them were subjected to early clamping of the umbilical cord and eleven to late clamping. The physiological variables recorded were respiration, EKG, surface EMG, EOG and EEG. The recordings lasted six hours. Computer processing techniques were used in the working through of the analogue data.
