Comparative StudyAdditional value of two-channel amplitude integrated EEG recording in full-term infants with unilateral brain injury.
Amplitude integrated electroencephalography (aEEG) is a valuable tool for evaluating neonatal encephalopathy and identifying electrographic seizures. ⋯ Although there were no major differences found between seizure detection with one-channel or two-channel aEEG, in a subgroup of infants with a predominantly unilateral brain lesion, two-channel recording did provide additional information with identification of more seizure patterns on the affected side, sometimes also associated with a difference in BGP. To improve early diagnosis of unilateral lesions and improve seizure detection in these infants, routine use of two-channel recordings is recommended.

Accuracy of amplitude integrated EEG in a neonatal cohort.
To determine the sensitivity and specificity of amplitude integrated electroencephalogram (aEEG) compared to simultaneous standard electroencephalogram (sEEG) for seizure detection and background discontinuity. ⋯ Background abnormalities were detected with fair accuracy by aEEG but aEEG criteria alone would result in the overdiagnosis of neonatal seizures. Therefore seizures noted on aEEG require sEEG confirmation prior to implementing anticonvulsant therapy for neonatal seizures.

Changes in heart rate in the first minutes after birth.
The normal range of heart rate (HR) in the first minutes after birth has not been defined. Objective To describe the HR changes of healthy newborn infants in the delivery room (DR) detected by pulse oximetry. Study Design All inborn infants were eligible and included if a member of the research team attended the birth. ⋯ Conclusions The median HR was <100 bpm at 1 min after birth. After 2 min it was uncommon to have a HR <100 bpm. In preterm infants and those born by caesarean section the HR rose more slowly than term vaginal births.

Regional tissue oxygenation in association with duration of hypoxaemia and haemodynamic variability in preterm neonates.
To assess the effect of the duration of spontaneous hypoxic episodes and variations in haemodynamic parameters on cerebral and renal tissue oxygenation (rSo(2)C and rSo(2)R) in clinically stable preterm infants. ⋯ Prolongation of hypoxaemia contributes to the severity of the deoxygenation (systemic and regional) and development of bradycardia. In stable preterm neonates, mild decreases in MBP independently affect the renal but not cerebral tissue oxygenation and oxygen utilisation.
