Emergence delirium from ketamine is typically treated with which medication?

• A. Midazolam (Versed)
• B. Fentanyl
• C. Sodium thiopental
• D. Propofol

Answer: (A)

Emergence delirium after ketamine is best addressed with a short-acting sedative that provides anxiolysis, sedation, and amnesia. Midazolam fits this role well: it quickly quiets agitation caused by dissociative anesthesia, reduces the dissociated, psychomimetic experience, and can be easily titrated in the recovery area. Its benzodiazepine action enhances GABA-A signaling, which dampens CNS hyperexcitability that ketamine can provoke during emergence. This makes midazolam a preferred first-line option for this scenario. Fentanyl focuses on analgesia and doesn’t reliably curb delirium; it may even complicate the picture by adding sedation without addressing the dissociative symptoms. Sodium thiopental is a longer-acting barbiturate with less controllable sedation and drug recovery, not ideal for treating emergence delirium. Propofol can calm agitation but carries a risk of deeper sedation and respiratory depression, making midazolam the more practical initial choice for targeted management of ketamine-induced emergence delirium.
