Dilaudid vs. Fentanyl?

I HAd surgery last Friday a repeat of a surgery I had lst Sept. It was a cervical disc de-compression. I checked into pre-op at 10:00 Am as directed. To make a long story short an emergency brain absess went before me. So I was stuck in pre-op for 8 hours. The gave me fentayl twice without results. I told them fentanyl never has worked for me. They then gave me demoral which worked fine. I awoke from surgery and they have me hooked up to PCA with fenanyl. Needless to say I suffered without pain relief for the next 12 hours without and sleeep or relief. I asked to see the charge nurse and explained that something needed to be done or I would just go home. The Doctor whows up 12 hours later and puts me on Demoral/vistiril with great results. I was released today. I for the lfie of can't understand how tis could happen. One nurse also gave me vistiril IV and it almost burned my arm off. Thank God the surgery went well.

The question asked of you as to the strength difference between Dilaudid and fentanyl is vague; and, ought to be restated into a concrete question such as: degree of pain relief? or, equianlgesic dose? or, drug onset? or, drug duration? Only then, could you give an accurate answer. Dilaudid (hydromorphone) and fentanyl (sublimaze) each potentially produces the same degree of pain relief. Dilaudid (hydromorphone) equianlgesic dose is 0.15 mg; whereas, fentanyl (sublimaze) equianlgesic dose is 10-25 mcg. The onset is different: Dilaudid (hydromorphone) 2-5 minutes; fentanyl (sublimaze) 1-2 minutes. The duration is different: Dilaudid (hydromorphone) 2-4 hours; fentanyl (sublimaze) 1-1.5 hours.
