Epileptiform electroencephalogram during mask induction of anesthesia with sevoflurane.
BACKGROUND Sevoflurane is suggested as a suitable anesthetic agent for mask induction in adults. The authors recently found that hyperventilation during sevoflurane-nitrous oxide-oxygen mask induction is associated with cardiovascular hyperdynamic response. We tested the hypothesis that the hyperdynamic response can be explained by electroencephalography (EEG) findings. METHODS Thirty women w...
متن کاملPermutation Entropy for the Characterisation of Brain Activity Recorded with Magnetoencephalograms in Healthy Ageing
The characterisation of healthy ageing of the brain could help create a fingerprint of normal ageing that might assist in the early diagnosis of neurodegenerative conditions. This study examined changes in resting state magnetoencephalogram (MEG) permutation entropy due to age and gender in a sample of 220 healthy participants (98 males and 122 females, ages ranging between 7 and 84). Entropy w...
متن کاملEpileptiform Activity Patterns in Coupled Neuronal Networks
We evaluate occurrence of seizure-like activity in computational network models based on the histology of mammalian cortex. In the simulations, seizure onset activity in a network (active patch) is connected to a larger patch of cells (passive patch). The following scenarios were investigated: (1) the activeand passive patches are contiguous with all connectivity intact; (2) active and passive ...
متن کاملPermutation entropy of the electroencephalogram: a measure of anaesthetic drug effect.
BACKGROUND It would be useful to have an open-source electroencephalographic (EEG) index of gamma-amino-butyric acid (GABA)-ergic anaesthetic drug effect that is resistant to eye-blink artifact, responds rapidly to changes in EEG pattern, and can be linked to underlying neurophysiological and neuropharmacological mechanisms that control the conscious state. METHODS The EEG waveform can be des...
متن کاملPermutation entropy
Permutation entropy is computationally efficient, robust to outliers, and effective to measure complexity of time series. We used this technique to quantify the complexity of continuous vital signs recorded from patients with traumatic brain injury (TBI). Using permutation entropy calculated from early vital signs (initial 10~20% of patient hospital stay time), we built classifiers to predict i...
