Abstract
Concerning the recirculation of an inhalation anesthetic in a closed or semiclosed anesthetic system, the object of the invention is removing carbon dioxide gas from the exhalation of the patient under inhalation anesthesia by using an absorbent which hardly causes decomposition of the anesthetic remaining in the exhalation. The object is accomplished by using a magnesium compound such as magnesium oxide, magnesium hydroxide or magnesium hydroxycarbonate as the principal material of the absorbent to absorb carbon dioxide gas. It is preferred to use magnesium hydroxide with addition of a small amount of water.
