Bispectral index-guided induction of general anaesthesia.
Editor—We read with great interest the recent article by Petrun and Kamenik regarding the use of a bispectral index (BIS) monitor as a guide to induce anaesthesia using an infusion technique with propofol compared with etomidate. This infusion technique is a plausible concept because of the BIS monitoring. Infusion techniques using propofol were performed many years ago, dating back to 1983–7 w...
متن کاملBispectral index monitoring during electroconvulsive therapy under propofol anaesthesia.
BACKGROUND The accuracy of the bispectral index (BIS) as a monitor of consciousness has not been well studied in patients who have abnormal electroencephalograms (EEG). METHODS We studied the changes in BIS, its subparameters, and spectral entropy of the EEG during 18 electroconvulsive treatments under propofol and succinylcholine anaesthesia. A single bifrontal EEG, and second subocular chan...
متن کاملEEG-based indices of anaesthesia: correlation between bispectral index and patient state index?
BACKGROUND AND OBJECTIVE Both the bispectral and the patient state indices are derived from the electroencephalogram and have been proposed as a measure of the same clinical target, the hypnotic component of anaesthesia. The present study evaluated whether there is concordance between the bispectral and the patient state indices with regard to end-points measured simultaneously in patients unde...
متن کاملA new closed-loop control system for isoflurane using bispectral index outperforms manual control.
BACKGROUND Automatic control of depth of hypnosis using the Bispectral Index (BIS) can help to reduce phases of inadequate control. Automated BIS control with propofol or isoflurane administration via an infusion system has recently been described, a comparable study with isoflurane administration via a vaporizer had not been conducted yet. Our hypothesis was that our new model based closed-loo...
متن کاملPAEDIATRIC ANAESTHESIA Performance of entropy and Bispectral Index as measures of anaesthesia effect in children of different agesy
Background. Entropy and Bispectral Index (BIS ) have been promoted as EEG-based anaesthesia depth monitors. The EEG changes with brain maturation, but there are limited published data describing the characteristics of entropy in children, and some data suggest that BIS is less reliable in young children. The aim of this study was to compare the performance of entropy as a measure of anaesthetic...
