Q: What is the dose of Fentanyl in blunting the sympathetic response to laryngoscopy and intubation?

Answer: 3 mcg/kg

Recommended doses for pretreatment for intubation is 3 mcg/kg to avoid hypotension in patients dependent on sympathetic tone. Fentanyl has been described to cause thoracic and abdominal muscular rigidity but the incidence is extremely low and usually only happens when doses higher than 15 mcg/kg are used.
