What is the maximum fentanyl dose for post-intubation analgesia?

• A. 100 mcg
• B. 50 mcg
• C. 200 mcg
• D. 25 mcg

Answer: (A)

In post-intubation analgesia, the goal is to provide enough opioid relief without causing oversedation or respiratory compromise after airway management. Fentanyl is very potent and can depress ventilation and drop blood pressure, so many protocols set a strict limit on how much you can give in one dose.

The maximum single dose allowed for post-intubation analgesia is 100 micrograms. This cap helps balance effective analgesia with patient safety, reducing the risk of significant respiratory depression or hemodynamic instability. Doses smaller than that (like 50 or 25 mcg) may be insufficient in some patients, while a dose of 200 mcg would exceed the protocol’s safety limit. If more analgesia is needed, you would titrate per protocol rather than exceeding the 100 mcg per administration.
