on scalp blood, such as measurement of lactate concentration, do not appear to improve diagnostic accuracy. Results of direct intrapartum monitoring of the neurological state of the fetus by electroencephalogram recordings'8 19 are difficult to interpret and once again probably identify only severe fetal distress. Against a background of slow technical progress there has been an increasing dema...

Psychological status monitoring with cerebral blood flow (CBF), EEG and EOG measurements are attempted. Through experiments, it is confirmed that the proposed method for psychological status monitoring is valid. It is also found correlations among the amplitudes of peak alpha and beta as well as gamma frequency of EEG signals and EOG as well as cerebral blood flow. Therefore, psychological stat...

Rett syndrome is a neurodevelopmental disorder that almost exclusively affects females. The clinical course as well as the electroencephalogram pattern are characteristic and have been correlated to the clinical stages of the disease. Sixty to 70 percent of the patients develop epilepsy. The aim of this retrospective study was to investigate the correlation between clinical stages and electroen...

Propofol is an emulsion formulation of 2,6 diisopropylphenol developed in 1975. Widely recognized, it offers beneficial effects compared with other sedative drugs. Propofol is used in several clinical situations including multiple surgical procedures and critical-care medical conditions. Since technological advances over recent years have allowed an ever-increasing number of patients undergoing...

A 47-year-old man presented with tonic-clonic seizures characterized by convulsions. He repeatedly exhibited despite treatment four anti-seizure medications. During the titration process of perampanel (PER), paradoxically increased in intensity and frequency, resulting trauma. Video electroencephalogram monitoring revealed interictal rapid rhythms generalized spikes documented atonic seizures. ...

799 April 2014 O VER the last decade, scores of different algorithms have been proposed which extract some number from the raw electroencephalogram purporting to estimate some sort of “depth of anesthesia”—and more specifically—whether the patient is conscious or not. All of these algorithms seem to be correct approximately 65 to 85% of the time. In this issue of AnEsthEsIology, schneider et al...
