Estudo vídeo-polissonográfico em recém-nascidos de termo pequenos para a idade gestacional

video-polygraphic-eeg studies were performed in the first 24 life-hours of 26 healthy full-term newborns without perinatal injuries. the neurological examination and cranial ultrasonography were normal. the newborns were divided into two groups: one, with full-term appropriate - birth weight 11 newborns (control group ) and the other with full-term low-birth weight 15 newborns. thirteen newborns of the second group had video-polygraphic-eeg study abnormalities. the most frequent abnormalities were found in 11 cases, as far as sleep architecture is concerned. also, when compared with the control group, 8 cases of an excessive amount of startles and 2 cases of low behavior activities were found. the results demonstrate the usefulness of video-polygraphic-eeg study in the full-term newborns with intra-uterine growth retard. this examination was sensitive to detect behavior, sleep architecture and eeg standard differences in the low birth-weight newborns as to the control group.
