Quantifiying the Depth of Oral Sedation Using Bispectral Index Monitoring
Purpose: To determine whether Bispectral Index Monitoring is an effective tool for quantifying sedation depth after the administration of oral drug regimens in children.Methods: This retrospective study reviewed the charts of 75 children who received oral conscious sedation for dental treatment. …

The Effect of Atropine on the Bispectral Index Response to Endotracheal Intubation during Propofol and Remifentanil Anesthesia
… intubation is accompanied by an increase in bispectral index (BIS). The purpose of this study was to evaluate the effect of atropine on the BIS response to endotracheal intubation during anaesthetic induction with propofol and remifentanil target controlled infusion (TCI). Fifty-six patients, …

Novel Incorportation Of Biomedical Engineering Algorithms (bispectral Index Guided Or Anesthetic Concentration Guided) In Real-Time Decision Support To Prevent Intraoperative Awareness Using An Electronic Anesthesia Information Mananagement System
… (EEG) monitoring using the bispectral index (BIS)] for the prevention of AWR. However, these trials were conducted in high risk populations, limiting generalizability.</p> <p>Research Hypothesis: Real-time decision support with Anesthesia Information Management System alerts …

L1-Adaptive Control for Anesthesia Delivery
… such that patients follow a prespecified Bispectral Index (BIS) profile. The controllers are then evaluated on their ability to reject the disturbances effects on the patients’ BIS trajectory that arise during the course of surgery. The controllers are designed using identification-based …

Electroencephalographic effects of general anaesthetics : a suite of clinical studies and theoretical models
… eye-movements, blinks, and frontalis EMG. 4) The Bispectral index (BIS) consisted of three subcomponents. The first two (BetaRatio and SynchFastSlow) probably reflected the loss of high-frequency activity that is associated with the transition from consciousness to unconsciousness. 5) The state of …

Pharmacokinetic and Pharmacodynamic Modelling to Advance Perioperative Anaesthesia and Analgesia
… electroencephalograph (EEG) response, using Bispectral Index (BIS), for multiple drug classes. I aimed to establish a model that could be used to simulate EEG response, as a cue of anaesthetic depth, in a human patient simulator (HPS). I developed a model for propofol-alfentanil BIS effects …

Feedback control of sedation and general anaesthesia
… aim was to add to the body of knowledge on the Bispectral Index (BIS). I also wrote a computer program (BISCLAN) that was used in all the studies as a BIS data management tool, and in some studies for manual or automatic control of a propofol infusion. Two studies did not involve feedback …

Measurements of adequacy of anesthesia and level of consciousness during surgery and intensive care
… subjects was studied, and the resistance of bispectral index (BIS) and Entropy to the signal artifacts was compared. The hypothesis was that in brain-dead subjects, most of the biosignals recorded from the forehead would consist of artifacts. The original EEG was recorded and State Entropy …
