I had surgery about one year ago. Gastric Bypass including having my gallbladder taken out. My pain level was around 8 most of the time(I have never rated my own pain a 10, a kidney stone came close with a 9, just seems there are things much more horrible that could happen).Morphine did not make my pain worse, but it also did not make it any better at all. After 3 doses with no response, I was switched to Dilaudid. The Dilaudid PCA with 0.2 mg dose Q 6min and no lockout max, took some, but not all of the pain. However, I was so "high" I did not really care, and according to my wife was talking to our cat, who needless to say was not in the hospital room.
The last of my 3 days in the hospital I was switched to PO Oxycodone, which seemed to control the pain much better then the IV meds. Not sure if that was the case, or if the pain just coincidently got less as the meds were switched. All this stuff together gave me urinary retention and constipation, and made me nauseous. It is beyond me why anyone would want to take this stuff any longer then needed.
The response people have seems to be very much different from case to case. So far in patients, I have seen that fentanyl works best as far as pain control goes, with the fewest side effects. Demerol seems to work well also, but makes most patient vomit even if given with Phenergan. Dilaudid does much better then Morphine. Many patients report best pain relief if they are on either acetaminophen or motrin along with the narcotic. It seems that they require much less narcs, with greater overall pain relief.
PO wise it seems patients do best with Oxycodone for pain relief, while Hydrocodone leaves them being less drowsy, but more loopy. Methadone works well with long term pain issues. Again these are just observations I have made over a few years. Plain old Motrin is still one of the meds that all patients give the best feedback on, but causes the most gastrointestinal side effects and should not be taken without the docs closely monitoring for bleeds.
