Anesthetic induction: overview

Contributor(s): Jo Murrell, Sheilah Robertson

Introduction

  • General anesthesia: a state of unconsciousness produced by controlled, reversible intoxication of the central nervous system during which the patient neither perceives nor recalls noxious stimuli.
  • Anesthetic agent: a substance which produces loss of consciousness in a controllable manner.
  • Anesthetic induction: the state achieved when anesthetic agent concentration in the brain is high enough.
  • Induction can be achieved using (alone or in combination):
    • Injectable agents administered intravenously or intramuscularly.
    • Volatile agents inhaled with a carrier gas.
