CLASSIFICATION OF ANESTHETIC AGENTS
As mentioned in Lesson 1, anesthesia is a partial or complete loss of sensation,
with or without loss of consciousness, as a result of a disease, an injury, or
administration of a drug. Inhalation anesthesia has been classified as the most popular
because of its controllability. The intake and elimination of the agent is, in large
measure, affected by pulmonary ventilation. The three classifications of anesthetic
agents are general, regional or block, and local.
