General Anesthesia

A type of anesthesia that causes complete loss of sensation and consciousness throughout the entire body, usually induced by inhalational or intravenous drugs.

Stage 1 of General Anesthesia

Characterized by amnesia and analgesia; the patient is conscious but pain perception diminishes. Breathing and reflexes are maintained.

Stage 2 of General Anesthesia

Delirium stage; patient loses consciousness, exhibits struggling movements, irregular breathing, and dilated pupils.

Stage 3 of General Anesthesia

Surgical anesthesia stage; the patient is deeply unconscious and suitable for surgery with regular breathing and decreased reflexes.
