“…We can compare results in prematures with those obtained in our earlier studies on full-term newborns, because, except for the treatment of REMs, we used similar analytic methods. However, we cannot easily compare our results with those of Parmelee et al (1967) who considered each period of 20 sec separately without reference to what occurred before and after; or with those of Schulte et al (1969) who disregarded periods of variations shorter than 3 min, since we disregarded variations lasting less than I min. We have also differentiated between body and localized motility and diffuse jerks, and have indicated the limits of the regular respiratory rate, both of which have not been generally done.…”

Unite' de rech erches b io logiq u es n do-na tales (INSERM)Maternite ' Port-Royal, C The ontogenesis of sleep was studied in prematures from 32 t o 41 weeks of gestational age The characteristics of the EEG, the patterns and rate of respiration, the cardiac rate, body motility comprised of localized and diffuse movements, localized and diffuse jerks, clonic movements and electromyographic activity of the chin, as well as periods of total quietness were observed and correlated with the progressive organization of behavior in these infants. The data obtained at each gestational age, i.e., at 32-34 weeks, 35-37 weeks, and 38-41 weeks, were compared to those obtained in full-term newborns. The relationships between the different events and the features of the EEG and of the respiratory patterns were ascertained and compared to similar data obtained in the full-term newborn. This comparison shows that the premature at 40 weeks of gestational age has not attained a level of organization as high as that of the full-term newborn. An hypothesis suggesting a possible mechanism of this discrepancy is presented.premature infant ontogenesis sleep cycle polygraphic study

RESUMO -Analisamos o exame video-polissonográfico de 26 recém-nascidos de termo (RNT) com 24 horas de vida. Os RN tinham exame neurológico e ultrassonográfico cerebral normais e apresentaram período perinatal isento de complicações. Foram subdivididos em dois grupos, um controle constituído de 11 RNT com peso adequado para a idade gestacional; e um grupo de 15 RN com peso abaixo do esperado para o termo (RNT-PIG). Do segundo grupo, 13 RN apresentaram algum tipo de alteração ao exame video-polissonográfico. As alterações mais frequentes foram na arquitetura do sono, 11 casos, e no comportamento, em que oito RN apresentaram número excessivo de sobressaltos ("startle") em relação ao grupo controle e dois RN uma atividade motora reduzida. Os resultados deste estudo demonstram a utilidade da video-polissonografia quando aplicada a RNT-PIG. O exame mostrou-se sensível em detectar diferenças no comportamento, arquitetura do sono e padrão eletrencefalográfico dos RNT-PIG quando comparados ao grupo controle. PALAVRAS-CHAVE: polissonografia neonatal, RNT-PIG, EEG neonatal. Video-polygraphic-EEG study in the full-term newborn with low birthweight for their gestational ageABSTRACT -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 videopolygraphic-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.

“…Studies in the human newborn have dem onstrated abnormalities in sleep patterns in infants of diabetic mothers [13], in small for AGA infants of toxemic mothers [14], and in infants whose mothers were alcoholic [15]. Documentation of active and quiet periods of fetal activity in the normal appropriate for gestational age fetus may provide not only a baseline with which to compare specific groups of fetuses at risk, such as the diabetic, hypertensive and drug-abusing patient, but may also provide a basic for beginning stud ies on the origin of human behavioral matu ration.…”

Cyclic patterns of active and quiet fetal activity were evaluated in 36 clinically normal gravidas between 27 and 42 weeks of gestation. All infants were subsequently delivered between 37 and 42 weeks of gestation, were clinically normal and of appropriate weight for gestational age. Active-quiet cycles occurred less frequently and were of longer duration with increasing gestational age. Regression analysis of the number of active-quiet cycles with gestational age yielded a correlation coefficient of 0.52 (p < 0.01). The similarity of fetal active-quiet cycles and active and quiet sleep cycles observed after birth is noted.
