Changes in Resting Neural Connectivity during Propofol Sedation
BACKGROUND The default mode network consists of a set of functionally connected brain regions (posterior cingulate, medial prefrontal cortex and bilateral parietal cortex) maximally active in functional imaging studies under "no task" conditions. It has been argued that the posterior cingulate is important in consciousness/awareness, but previous investigations of resting interactions between t...
متن کاملChanges in Effective Connectivity by Propofol Sedation
Mechanisms of propofol-induced loss of consciousness remain poorly understood. Recent fMRI studies have shown decreases in functional connectivity during unconsciousness induced by this anesthetic agent. Functional connectivity does not provide information of directional changes in the dynamics observed during unconsciousness. The aim of the present study was to investigate, in healthy humans d...
متن کامل[Dexmedetomidine/propofol association for plastic surgery sedation during local anesthesia.].
BACKGROUND AND OBJECTIVES Dexmedetomidine is a new alpha2-adrenergic receptor agonist with potentially useful characteristics for anesthesia. This comparative study aimed at evaluating the effects of dexmedetomidine on propofol requirements and cardiovascular/respiratory stability during plastic surgery sedation under local anesthesia. METHODS Participated in this study 40 female patients age...
متن کاملPropofol and fospropofol sedation during bronchoscopy.
We read with interest the excellent editorial by Michael Jantz (January 2009) 1 that nicely summarized the existing data on the safety of propofol for pulmonary endoscopy. We would like to add that propofol also has an excellent record of safety for GI endoscopy. A recently published study documented the safety of propofolassisted sedation in . 500,000 patients undergoing various GI endoscopies...

relationship between plasma concentration and effect. We would agree that the assumption of first-order intercompartmental drug transfer is a simplification of what must obtain in the muscle in vivo, and it may be that further refinement of the link model will bring closer agreement between observations and model predictions. Such refinement would add further model parameters, and, in our view,...
