Neurologic changes during awakening from anesthesia.

abstract：BACKGROUND:Myocardial contractility is regulated by intracellular concentration of free Ca2+ ([Ca2'],) and myofilament Ca2+ sensitivity. The objective of this study was to elucidate the direct effects of thiopental on cardiac excitation-contraction coupling using individual, field-stimulated ventricular myocytes. METH...
