Official title:
Can Fentanyl Lead to Opioid-induced Hyperalgesia in Healthy Volunteers? A Prospective, Randomized, Double-blinded Crossover Study
The purpose of this study is to examine whether two clinically sensible dose regimen of
fentanyl (low dose vs. high dose) lead to different pain scores as measured by the nonverbal
rating scale (NRS) in healthy volunteers at 4.5 to 6.5 hours after fentanyl application.
Pain modalities tested will include transdermal electrical stimulation and cold pressor
pain.
The investigators hypothesize that the high dose fentanyl group will have an increase of
approximately 20% in the NRS.
