What is a noted side effect of ketamine?

• A. Decreased blood pressure
• B. Respiratory depression
• C. Vivid dreams and illusions
• D. Prolonged sedation

Answer: (C)

Ketamine is known for its unique properties as an anesthetic agent, often used for its dissociative anesthetic effects. One notable side effect is the occurrence of vivid dreams and illusions, which is a result of ketamine's action on the central nervous system. This side effect typically arises during and after administration when patients may experience altered perceptions, including hallucinations and vivid imagery. Such experiences can be categorized under dissociative effects that patients report when waking from anesthesia. The phenomenon of vivid dreams and illusions is significant because it underscores the importance of preoperative counseling for patients regarding what they may experience during recovery. This preparation can help alleviate any confusion or anxiety about these unexpected sensory experiences. Other potential side effects of ketamine do exist, but they tend to differ in nature. For example, while respiratory depression can occur, it is less common with ketamine compared to other anesthetic agents, as ketamine generally maintains respiratory function. Decreased blood pressure and prolonged sedation also do not capture the hallmark psychological effects associated with ketamine; they are more frequently noted with other agents or circumstances surrounding anesthesia. Thus, the defining characteristics of ketamine's effects make vivid dreams and illusions the most noted side effect.
