Auditory information processing during adequate propofol anesthesia monitored by electroencephalogram bispectral index.
UNLABELLED Memory for intraoperative events may arise from inadequate anesthesia when the hypnotic state is not continuously monitored. Electroencephalogram bispectral index (BIS) enables monitoring of the hypnotic state and titration of anesthesia to an adequate level (BIS 40 to 60). At this level, preserved memory function has been observed in trauma patients. We investigated memory formation...
متن کاملARX-derived auditory evoked potential index and bispectral index during the induction of anesthesia with propofol and remifentanil.
UNLABELLED A new commercial auditory evoked potential (AEP) monitor (A-line AEP monitor) was developed to calculate an index (ARX AEP index; AAI) by automatically using the amplitudes and latencies of the AEP. We investigated 30 patients before spine surgery. AAI; bispectral index (BIS); relative (%) delta, theta, alpha, and beta; spectral edge frequency; median frequency; mean arterial blood p...
متن کاملCorrelation and agreement between bispectral index and state entropy of the electroencephalogram during propofol anaesthesia.
BACKGROUND Bispectral index (BIS) and state entropy (SE) monitor hypnosis. We evaluated the correlation and the agreement between those parameters during propofol anaesthesia and laryngoscopy with and without muscle relaxation. METHODS A total of 25 patients were anaesthetized with propofol. At steady state (SS: BIS 40-50), they randomly received rocuronium (R) or saline (S); 3 min thereafter...
متن کاملClonidine premedication decreases propofol consumption during bispectral index (BIS) monitored propofol-ketamine technique for office-based surgery.
BACKGROUND Propofol-ketamine anesthesia is a room air, spontaneous ventilation (RASV), dissociative intravenous (IV) sedation technique reported to have a near-zero postoperative nausea and vomiting (PONV) rate. Clonidine premedication has been reported to control blood pressure intra- and postoperatively, as well as to reduce the requirements for hypnotic agents. The bispectral index (BIS) mon...
متن کاملEffect of propofol titration v/s bolus during induction of anesthesia on hemodynamics and bispectral index.
BACKGROUND Propofol when given as 2 mg/kg IV bolus for induction of anesthesia is known to cause hypotension requiring vasopressors. The objective of our study was to compare Propofol 2 mg/kg single IV bolus (Precalculated group, PG) with the titration of Propofol (Titration group, TG) to clinical parameters as 10 mg IV increments every 3 seconds on hemodynamic Parameters and Bispectral Index (...
