Which stage features delirium and excitation, retching, and irregular respiration?

• A. Analgesia
• B. Disinhibition
• C. Surgical anesthesia
• D. Medullary depression

Answer: (B)

Guedel’s stages of anesthesia show a progression from light to deep anesthesia. The features described—delirium and excitation, retching, and irregular respiration—are characteristic of the second stage, often called the disinhibition or delirium/excitation phase. In this stage the patient is not fully conscious, may be agitated or restless, and autonomic activity is erratic, leading to irregular breathing and vomiting. This contrasts with the first stage (analgesia), where the patient is calm with analgesia and relatively normal respiration; the third stage (surgical anesthesia) involves deeper anesthesia with loss of reflexes but more regular and controlled respiration; and the fourth stage (medullary depression) features profound brainstem depression with apnea and potential cardiovascular collapse. So the described symptoms fit the disinhibition stage.
