Correlation of bispectral index with end-tidal sevoflurane concentration and age in infants and children.
BACKGROUND The bispectral index (BIS) has been evaluated as a tool for measuring depth of anaesthesia, but the use of BIS in a paediatric population is still controversial. This study was designed to evaluate the correlation of BIS with end-tidal sevoflurane concentration and age in infants and children. METHODS Eighty-one patients undergoing elective urology surgery were allocated into three...
متن کاملRelationships between Bispectral Index, Implicit Memory, Dream Recall and Minimum Alveolar Concentration in Blended Anaesthesia
The decreased responsiveness to stimulation defines the depth of anaesthesia which is a balance between effects of anaesthetic drugs and surgical stimulations. Awareness is a rare occurrence with an incidence of 0,1-0,2 %1, defined as postoperative recall of events occurring during general anaesthesia. This memory can be traumatic and may result in developing a chronic posttraumatic stress diso...
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 کاملThe correlation of bispectral index with endtidal sevoflurane concentration and haemodynamic parameters in preschoolers.
BACKGROUND Bispectral index (BIS) is a signal processing device that potentially is a pharmacodynamic measure of the effects of anaesthesia on the central nervous system. METHODS In this prospective blinded study, we investigated the pharmacodynamic relationship between BIS, haemodynamic changes during anaesthesia and endtidal nonsteady state concentrations of sevoflurane in 30 children, mean...
متن کاملRelationship between Sevoflurane Plasma Concentration, Clinical Variables and Bispectral Index Values during Cardiopulmonary Bypass
BACKGROUND Anesthetic administration is increasingly guided by electroencephalography (EEG)-based monitoring, such as the bispectral index (BIS). However, during cardiopulmonary bypass (CPB), factors other than the administered hypnotic agents may influence EEG signals, and their effects on BIS values are unknown. METHODS This report is a secondary analysis of data from a prospective, control...
