Cardiovascular System:Fentanyl can cause bradycardia (slow heart rate) and hypotension, though it is generally considered more cardiovascularly stable than morphine.

Musculoskeletal System:An unique side result of quick, high-dose fentanyl administration is "wood chest syndrome" (skeletal muscle rigidness), which can make mechanical ventilation tough.
