AIM: To determine whether moderate hypothermia, applied after a hypoxic-ischaemic insult in neonatal rats, reduces cerebral damage. METHOD: Unilateral hypoxic-ischaemic brain damage was induced in 7 day old rats by left carotid ligation, followed by

To evaluate the frequency content of the electroencephalogram (EEG) during recovery after a severe hypoxic insult in newborn piglets.EEG was continuously monitored in nine newborn piglets exposed to a severe hypoxic period. Power spectra in five freq

Excitatory amino acids (EAAs) have been implicated to play a part in the development of hypoxic-ischemic brain injury in the neonate. The aim of the present study was to follow changes of intra- and extracellular (microdialysis) amino acids in the ce

A novel measure of spectral distance is presented, which is inspired by the prediction residual parameter presented by Itakura in 1975, but derived from frequency domain data and extended to include autoregressive moving average (ARMA) models. This n

Hypoxia/ischaemia is the most common cause of brain damage in neonates. Thousands of newborn children suffer from perinatal asphyxia every year. The cells go through a response mechanism during hypoxia/ischaemia, to maintain the cellular viability an

In the search for how neonatal EEG is affected by asphyxia it is of importance to find reliable estimates of EEG power spectra. Several spectral estimation methods do exist, but since the true spectra are unknown it is hard to tell how well the estim

OBJECTIVE: To investigate whether very low EEG frequency activity can be recorded from post asphyctic full term neonates using EEG equipment where the high pass filter level was lowered to 0.05 Hz. METHODS: The time constant of the amplifier hardware

OBJECTIVE: To investigate whether the periodic EEG patterns seen in healthy and sick full term neonates (trace alternant and burst suppression, respectively) have different frequency characteristics. METHODS: Burst episodes were selected from the EEG

Publisher Summary In an intensive care, a number of physiologic parameters are monitored. Therefore, many different pieces of equipment, each concerned with one or a few measurements are employed. Ideally, a monitoring system should be able to handle
