Which is a first-line analgesic for moderate to severe burn pain?

• A. NSAIDs
• B. Opioids (e.g., morphine, fentanyl)
• C. Regional anesthesia or local anesthetics as adjuncts
• D. Acetaminophen

Answer: (B)

Severe burn pain requires potent, controllable analgesia that can be titrated to match intense nociceptive input and the needs of wound care. Opioids provide strong, reliable pain relief by activating mu receptors in the central nervous system, which reduces both the perception of pain and the emotional response to it. This makes them the most appropriate first-line choice for moderate to severe burn pain, especially in the acute setting with dressing changes or procedures that provoke spikes in pain.

Nonopioid options like NSAIDs address inflammation and can help with mild to moderate pain, but they often aren’t strong enough on their own to control severe burn pain. Acetaminophen is useful as part of a multimodal approach, yet it typically doesn’t provide sufficient relief for intense burn pain when used alone. Regional anesthesia or local anesthetics are valuable adjuncts for specific procedures or to reduce pain in a particular area, but they don’t replace systemic opioid analgesia for widespread or ongoing severe pain.

In practice, a multimodal strategy combines opioids with nonopioid analgesics and, when appropriate, regional techniques to optimize pain control while minimizing opioid-related side effects.
