In medical research, rats are widely used as common research objects. In more medical and zoological research, rat anesthesia is required first, and some special disciplines such as pharmacy, neuroscience, anesthesiology, etc. The focus of research is often on the effects of anesthesia or the anesthetic itself on rats. Inhalation anesthesia refers to anesthesia in which the anesthetic is inhaled through the respiratory tract, resulting in depression of the central nervous system, causing the patient to temporarily lose consciousness and not feel pain around the body. The method is the main method of general anesthesia. The depth of anesthesia is related to the partial pressure of the drug in the brain tissue. When the anesthetic is excreted from the body or metabolized in the body, the patient gradually regains consciousness without any sequelae. Inhalation anesthesia is in the body.
