We assessed the effects of a familiar odor during routine blood draws in healthy preterm newborns. Infants were observed as they were undergoing either a capillary puncture on the heel (heelstick) or a venous puncture on the hand. During the procedure, one third of the infants were presented with an odor they had been familiarized with prior to the(More)
The maternal administration of betamethasone and thyrotropin releasing hormone (TRH) to accelerate the maturation of the fetus is an increasingly adopted strategy to prevent neonatal morbidity in preterm infants. The effect of this prenatal treatment on the neural maturation of the infant was assessed by measuring somatosensory evoked potentials (SEP) in(More)
This study was aimed at assessing by EEG recording and cranial imaging the cerebral function of 29 full term newborns presenting with hypoxic-ischemic encephalopathy and at establishing a correlation between the results and the neurological outcome. A correlation between the Sarnar's classification and the neurological outcome was observed, except for the(More)
Thirty-nine preterm infants were studied to compare the predictive value of somatosensory evoked responses (SEPs) following median-nerve and posterior tibial-nerve stimulation with the predictive value of cranial ultrasound. With regard to the SEP, a normal median-nerve response was by no means a guarantee of a normal outcome. A normal posterior(More)
Somatosensory evoked potentials (SEPs) were performed between 31 and 49 weeks postmenstrual age on 33 neonates with extensive cystic leukomalacia. 27 had periventricular leukomalacia (PVL), while six had deep white matter lesions. All but two of the 27 infants with PVL had a reproducible potential at discharge, being delayed in 11 and within the normal(More)
One hundred and twenty six preterm infants, with a gestational age of 34 weeks or less, were studied to compare the predictive value of somatosensory evoked potentials (SEPs) with that of cranial ultrasound. A normal N1 latency was no guarantee of a normal outcome, nor did a persistently delayed N1 latency always correlate with a poor outcome. As a(More)
INTRODUCTION Neonatal traumatic head injuries (NTHI) can be life-threatening and require aggressive treatment. The indications, techniques, and results of brain decompression are not well defined in the literature. METHODS We studied prospectively cases of NTHI with intracranial traumatic lesions; skull fractures without underlying lesions were not(More)
In order to further evaluate both the maturation as well as the prognostic value of the somatosensory evoked potentials (SEPs) with regard to neurodevelopmental outcome, SEPs were performed after the first week of life in 56 small-for-gestational age (SGA) preterm neonates. Twenty-five had a prolonged N1 latency while 30 had a normal N1 latency around(More)
The data reported in the literature and our own findings have shown, that evoked potentials (EPs) can be performed at the bedside and provide additional information about the integrity of the central nervous system. Auditory brainstem responses (ABRs) are especially useful for early identification of audiological problems and whenever possible, at risk(More)
