Dexmedetomidine is not commonly used for postoperative analgesia mainly because of which reason?

• A. Limited analgesic efficacy.
• B. Expense and the need for an IV.
• C. Prolonged duration causing delayed discharge.
• D. High risk of respiratory depression.

Answer: (B)

Dexmedetomidine can provide sedation with some analgesia, but its routine postoperative analgesia use is limited mainly by practical drawbacks: it is expensive and must be given as an IV infusion. That means keeping an IV line active, arranging continuous monitoring, and incurring higher drug costs for relatively modest analgesic benefit. In most postoperative pain strategies, cheaper options with easy administration (like acetaminophen, NSAIDs, regional techniques, or short-acting opioids) are preferred, making the need for IV infusion and the associated expense the primary reason it isn’t commonly used. Its minimal impact on respiratory depression is a benefit, but it doesn’t counterbalance the cost and IV requirements in typical practice.
