Auditory processing during deep propofol sedation and recovery from unconsciousness.
OBJECTIVE Using evoked potentials, this study investigated effects of deep propofol sedation, and effects of recovery from unconsciousness, on the processing of auditory information with stimuli suited to elicit a physical MMN, and a (music-syntactic) ERAN. METHODS Levels of sedation were assessed using the Bispectral Index (BIS) and the Modified Observer's Assessment of Alertness and Sedatio...
متن کاملThalamus, Brainstem and Salience Network Connectivity Changes During Propofol-Induced Sedation and Unconsciousness
In this functional magnetic resonance imaging study, we examined the effect of mild propofol sedation and propofol-induced unconsciousness on resting state brain connectivity, using graph analysis based on independent component analysis and a classical seed-based analysis. Contrary to previous propofol research, which mainly emphasized the importance of connectivity in the default mode network ...
متن کاملThe Effect of Sedation on Heart Rate Variability during Transesophageal Echocardiography: a Comparison of Hypnotic Sedation with Medical Sedation
Background: There is no ideal sedation technique that can be used during Transesophageal Echocardiography (TEE) and the data concerning the effects of available sedation techniques on Heart rate variability(HRV) are limited. Our study aimed at comparing the effects of sedation through hypnotherapy with medical sedation achieved by midazolam on HRV. Methods: We recruited 76 patients with an indi...
متن کاملWhen there are no good choices: illuminating the borderland between proportionate palliative sedation and palliative sedation to unconsciousness.
BACKGROUND Despite state-of-the-art palliative care, some patients will require proportionate palliative sedation as a last-resort option to relieve intolerable suffering at the end of life. In this practice, progressively increasing amounts of sedation are provided until the target suffering is sufficiently relieved. Uncertainty and debate arise when this practice approaches palliative sedatio...
متن کاملAnesthesia and neuroimaging: investigating the neural correlates of unconsciousness.
In the past 15 years, rapid technological development in the field of neuroimaging has led to a resurgence of interest in the study of consciousness. However, the neural bases of consciousness and the boundaries of unconscious processing remain poorly understood. Anesthesia combined with functional neuroimaging presents a unique approach for studying neural responses as a function of consciousn...
