The premature infant brain has been thoroughly studied by sonography, and normal standards for ventricular size have been established. Whether these apply to normal full-term infants is uncertain. Fifty-three healthy full-term infants were electively examined by real-time sonography through the anterior fontanelle on the first to sixth days of life. Nine(More)
BACKGROUND Amplitude-integrated electroencephalography has become an important tool for assessing cortical status noninvasively. Newer units have the additional feature of visualizing the raw electroencephalogram, which has resulted in the identification of frequent artifacts. OBJECTIVE To highlight the problem of artifacts and to introduce caution when(More)
Using passive tipping to a 45 degrees head-up position, an attempt was made to elicit reflex vasoconstriction in 13 non-distressed preterm infants and 27 infants with hyaline membrane disease, all between 26 and 38 weeks gestation. An increase in vascular tone associated with a significant reduction in peripheral blood-flow was found in 11 of the 13(More)
Respiratory pattern and heart rate were studied in 28 pre-term infants and four full-term infants during the first weeks of life. Sleep state was identified by standard neurological and EEG criteria. Apneic spells lasting 10 seconds or more were most frequent in the least mature infants, and their frequency tended to diminish with increasing maturity. When(More)
