Is fentanyl being sold separately now or is it just being used as a cut? I had some education on work about conscious sedation last night. Dilaudid is between 5-7 times more potent than morphine. I've known that one for a while. You ready for this... Fentanyl is 75-125 times more potent than morphine. Sometimes we use it fur ventilator sedation. Max rate is 200 micrograms/hr. That is 0.2 milligrams an hour. At that rate, the Fucking person is out cold and you can turn their body side to side and get no reaction. Unless they have a tolerance related to opioid abuse.
