Which modality is specifically designed for continuous pain control rather than rapid relief in children?

• A. Transdermal fentanyl patches
• B. Nitrous oxide
• C. TAC
• D. EMLA cream

Answer: (A)

The idea being tested is using a method that provides steady, ongoing pain relief rather than a quick, temporary fix. Transdermal fentanyl patches fit this need because they release fentanyl slowly through the skin, producing a constant level of analgesia over several days. This makes them ideal for chronic or persistent pain in children when continuous control is more important than rapid onset. They do take time to reach effective levels and are typically used in opioid-tolerant patients, with careful monitoring for respiratory depression and other opioid effects; they are not for immediate, short-lived relief.

In contrast, nitrous oxide acts quickly but wears off rapidly, so it’s used for short procedures rather than ongoing pain control. EMLA cream is a topical anesthetic used to numb skin for minor procedures and has a limited, procedure-focused duration. TAC, another topical anesthetic approach, provides surface numbness with local effect and does not offer sustained systemic analgesia.
