What is the typical small bolus dose of fentanyl?

• A. 5-10 mcg
• B. 100-150 mcg
• C. 1-5 mcg
• D. 25-50 mcg

Answer: (D)

Fentanyl is a highly potent, rapid-acting opioid used in anesthesia to provide analgesia and blunt autonomic responses with a relatively short duration. A small IV bolus should be large enough to be effective but not so large that it causes prolonged respiratory depression or chest wall rigidity. Doses in the 25-50 microgram range hit that balance well for opioid-naive adults: they provide meaningful analgesia and hemodynamic stability without the excessive risks that come with higher amounts. Smaller doses like 1-5 or 5-10 micrograms are typically too modest to achieve adequate analgesia, while 100-150 micrograms would be considered a large dose with greater risk of respiratory suppression and delayed recovery.
