Titration of propofol for anesthetic induction and maintenance guided by the bispectral index: closed-loop versus manual control: a prospective, randomized, multicenter study.
BACKGROUND This report describes a closed-loop titration of propofol target control infusion based on a proportional-differential algorithm guided by the Bispectral Index (BIS) allowing induction and maintenance of general anesthesia and compares this to manual propofol target control infusion. METHODS One hundred sixty-four patients scheduled to undergo elective minor or major surgery were p...
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 کاملComparison of the effects of different anesthetic techniques on electrocorticography in patients undergoing epilepsy surgery – A bispectral index guided study
AIM It is well known that general anesthetics suppress/alter electrocorticography (ECoG) activity. However there are no randomized studies available, comparing various anesthetic techniques as regards their effects on ECoG. METHODS The following is a double blind, randomized cross over study to compare the effects of isoflurane and propofol with or without nitrous oxide on electrocorticograph...

Background & Aims: This study was aimed to investigate whether BIS monitoring can improve recovery from propofol anesthesia and decrease the propofol requirement or no. Materials & Methods: In a randomized, prospective design, 20 patients received propofol, at target dose 100 µg/kg/min and intraoperative anesthetic management was blinded to BIS values, whereas in 20 patients propofol was titra...
