Graded hypercapnia and cerebral autoregulation during sevoflurane or propofol anesthesia.
BACKGROUND Hypercapnia abolishes cerebral autoregulation, but little is known about the interaction between hypercapnia and autoregulation during general anesthesia. With normocapnia, sevoflurane (up to 1.5 minimum alveolar concentration) and propofol do not impair cerebral autoregulation. This study aimed to document the level of hypercapnia required to impair cerebral autoregulation during pr...
متن کاملCerebral state index may reflect electrical brain activity during propofol or isoflurane anaesthesia in rabbits.
Approach Eighteen New Zealand white rabbits, undergoing surgical catheterisation of the bilateral carotid and internal jugular vein, were used in this study. In group I (propofol), anaesthesia was maintained with an intravenous (iv) infusion of propofol at a rate of 0.7 mg/kg/min and interval iv fentanyl. In group II (isoflurane), the end-tidal concentration was adjusted to 1.0 minimum alveolar...
متن کاملComparative Evaluation of the Cerebral State Index Tm and Bispectral Index Tm Monitoring during Propofol -remifentanil Anesthesia for Open Heart Surgery
Objective: The Cerebral State index (CSI) is a new index based on electroencephalogram to monitor depth of anesthesia. Transferring guidelines for titration of the Bispectral index (BIS) to the CSI depends on their compatibility. We compared the relationship between BIS and CSI values during propofol-remifentanil anesthesia. Methods: Forty one adult patients about to have open heart surgeries w...
متن کاملComparative evaluation of the cerebral state index and the bispectral index during target-controlled infusion of propofol.
BACKGROUND Cerebral state index (CSI) has recently been introduced as an intra-operative monitor of anaesthetic depth. We compared the performance of the CSI to the bispectral index (BIS) in measuring depth of anaesthesia during target-controlled infusion (TCI) of propofol. METHODS Twenty Chinese patients undergoing general anaesthesia were recruited. CSI and BIS, and predicted effect-site co...
متن کاملPatient State Index: titration of delivery and recovery from propofol, alfentanil, and nitrous oxide anesthesia.
BACKGROUND The Patient State Index (PSI) uses derived quantitative electroencephalogram features in a multivariate algorithm that varies as a function of hypnotic state. Data are recorded from two anterior, one midline central, and one midline posterior scalp locations. PSI has been demonstrated to have a significant relation to level of hypnosis during intravenous propofol, inhalation, and nit...
