OBJECTIVES Our aim was to characterize cerebral event-related responses, which index the detection of auditory stimuli during postoperative sedation. METHODS We monitored auditory event-related potentials (ERPs) before and after elective cardiac operation in 29 patients. Sedation levels, induced with propofol, were evaluated clinically with Ramsay score(More)
PURPOSE Appropriate treatment of generalized convulsive refractory status epilepticus (RSE) requires general anesthesia in the intensive care unit (ICU) with continuous electroencephalography (cEEG) monitoring. During out of office hours and weekends, cEEG monitoring is not always available. The Bispectral Index (BIS) monitor can be used to assess the(More)
We compared the primary metrics of the Spectral entropy M-ENTROPY™ module and BIS VISTA™ monitor—i.e., bispectral index (BIS), state entropy (SE), and response entropy (RE) in terms of agreement and correlation during general anesthesia for cardiac surgery. We also evaluated responsiveness of electroencephalogram (EEG)-based and hemodynamic parameters to(More)
OBJECTIVES Midlatency auditory-evoked potentials (MLAEPs) may provide an objective measure of depth of sedation. The aim of this study was to evaluate MLAEPs for measuring sedation in cardiac surgery patients. DESIGN Prospective study. SETTING Intensive care unit of a university hospital. PARTICIPANTS Twenty-two patients scheduled for elective(More)
We report on the EEG monitoring of a patient who suffered an episode of postoperative ventricular fibrillation (VF) following coronary artery bypass grafting (CABG). VF initially caused a considerable suppression and slowing of the EEG. The recovery of cerebral function was evaluated by recording both EEG and auditory event related potentials (ERPs). Six(More)
OBJECTIVE To investigate whether levosimendan, an inotrope with cardioprotective properties, increases postoperative bleeding after cardiac surgery. DESIGN Retrospective analysis of a randomized, prospective clinical study. SETTING Post-anesthesia care unit (PACU) and surgical ward in a university hospital. PARTICIPANTS Two hundred heart valve surgery(More)
BACKGROUND Remifentanil, an ultra-short-acting opioid, provides intensive analgesia without prolonged respiratory depression and is widely used in cardiac surgery. Diminished dosing may also offer stable hemodynamics, even during sternotomy and sternal retraction. However, increased postoperative pain and induced opioid tolerance after remifentanil dosing(More)
