Remifentanil is being used increasingly as one component of total intravenous anesthesia. Severe postoperative pain has occasionally been reported with discontinuation of remifentanil. This study was designed to determine the involvement of conventional protein kinase Cgamma (cPKCgamma) in the inhibitory action of lidocaine on remifentanil-induced hyperalgesia of rats after propofol-remifentani...

BACKGROUND For years, undivided attention during the presurgical "timeout" has been utilized as a precaution to ensure patient safety.

Here the impact of this practice change is analyzed. METHODS Th...
