Abstract: A method for facilitating postoperative awakening of patients from anesthesia does not depend on the experience of anesthesiologists. Also provided are an anesthesia arousal composition for use in this method and a preparation containing a bicarbonate ion that facilitates awakening from anesthesia. Specifically, the anesthesia arousal composition is provided in the form of infusion fluid. The method for controlling and facilitating awakening from anesthesia involves administering the anesthesia arousal composition. The present invention preferably provides an anesthesia arousal composition or an acidosis-correcting composition containing sodium bicarbonate as a major component that serves as a source of the bicarbonate ion, along with each or a combination of another electrolyte, glucose and an amino acid.
