  2. 1. Utility of bispectral index (BIS) monitoring during general anesthesia

    Author : Maj-Lis Lindholm; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The possibility to objectively measure effects from anesthetics on the level of consciousness has since long been desired. General anesthetics cause changes in brain electrical activity, seen as changes in the electroencephalogram (EEG). READ MORE

  4. 2. Analysis of regional seismic data by means of higher-order spectra

    Author : Leif Persson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Abstract : The use of higher-order statistical and spectral estimators as complementary analysis for conventional regional seismic data processing is studied. The issues addressed are; the properties of the complex bispectrum of regional seismic phases, the experimental detection performance of higher-order statistical detectors, discrimination between local earthquakes and explosions, statistical tests and bicoherence, biphase and spatial bispectrum analysis of regional P-, S, and Lg-phases.

  5. 3. Pharmacometric Models in Anesthesia and Analgesia

    Author : Marcus Björnsson; Ulrika Simonsson; Mats Karlsson; Leonid Gibiansky; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacometrics; Anesthesia; Analgesia; Dropout; NONMEM; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

    Abstract : Modeling is a valuable tool in drug development, to support decision making, improving study design, and aid in regulatory approval and labeling. This thesis describes the development of pharmacometric models for drugs used in anesthesia and analgesia. READ MORE

  6. 4. Hypnosis monitoring during general anaesthesia : with focus on awareness

    Author : Andreas Ekman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Hypnosis monitoring; electroencephalogram; BIS; AAI; neuromuscular block;

    Abstract : An objective measure of the hypnotic component of general anaesthesia has been sought for decades. The electroencephalogram (EEG) was early recognized as a possible useful intraoperative monitor when the effects of anaesthetic drugs on human EEG recordings were noted. READ MORE

  7. 5. Patient-controlled sedation in procedural care

    Author : Andreas Nilsson; Lena Nilsson; Folke Sjöberg; Eva Uustal; Lars I. Eriksson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The need for procedural sedation is extensive and on the increase in numbers of patients. Minor treatments or diagnostic procedures are being performed with inadequate sedation or even without any sedatives or analgesics. READ MORE
