Anterior shift of the dominant EEG rhytham during anesthesia in the Java monkey: correlation with anesthetic potency.

abstract：BACKGROUND:Despite decreasing cardiac events, perioperative beta-blockade also increases perioperative stroke and mortality. Major bleeding and/or hypotension are independently associated with these outcomes. To investigate the hypothesis that beta-blockade limits the cardiac reserve to compensate for acute surgical an...
