Which combination represents the three parts of anesthesia?

• A. Induction, Emergence, Recovery
• B. Induction, Maintenance, Emergence
• C. Onset, Duration, Recovery
• D. Sedation, Analgesia, Amnesia

Answer: (B)

General anesthesia is managed in three clinical phases: induction, maintenance, and emergence. Induction is the transition from awake to unconscious, using medications to rapidly achieve a controlled anesthetic state and secure the airway. Maintenance covers the intraoperative period, keeping the patient at a steady depth of anesthesia with ongoing airway management and monitoring. Emergence is the process of waking the patient from anesthesia, with return of consciousness and protective reflexes, followed by recovery in the immediate postoperative period. Recovery itself is postoperative care, not one of the intraoperative phases, which is why the combination of induction, maintenance, and emergence best represents the three parts of anesthesia. The other options mix pharmacologic terms or postoperative stages that don’t define the three-phase flow.
