What is the intravenous induction dose range for fentanyl in adults?

• A. 0.5-1 mcg/kg
• B. 3-5 mcg/kg
• C. 5-7 mcg/kg
• D. 1-3 mcg/kg

Answer: (C)

Fentanyl is used during induction to provide rapid analgesia and blunt the sympathetic response to airway manipulation. Because it’s highly potent and has a rapid onset, a relatively large IV dose is given to achieve reliable analgesia and hemodynamic stability when the hypnotic agent is administered. A typical induction dose in adults is about five to seven micrograms per kilogram. This level reliably blunts the pressor response to laryngoscopy and intubation and adds analgesia during the early maintenance phase. Doses lower than this often don’t provide sufficient blunting or analgesia, while higher doses require close monitoring for respiratory depression and other opioid-related effects. In practice, clinicians tailor the dose to the patient’s age, cardiovascular status, and other concurrent medications, but five to seven mcg/kg is a commonly cited range for intravenous induction in adults.
