A. True. Guedel described four stages of anaesthesia. The second stage is known as the excitement or uninhibited response stage.
B. False. Air exchange in theatre does reduce pollution from inhalational agents, but the recommended turnover is 20 cycles per hour.
C. False. Central core disease is associated with susceptibility to malignant hyperthermia. Volatile agents may precipitate malignant hyperthermia in susceptible individuals.
D. True. Heavy smoking is associated with upper airway irritability, which may be aggravated by inhalational agents.
E. True. Reduced salivary secretions will make airway management easier. Also, deep volatile anaesthesia may cause bradycardia, which may be prevented by using an anticholinergic (e.g. glycopyrronium).
