Had a morbidly obese (500lb) patient last night with a femur fx. ED was giving 1mg of Dilauded IV without much effect on patients pain. Pt. stated the 1mg barely decreased the pain and was rating 8/10 on my assessment with evidence of pain response. Pt. appeared very uncomfortable.
ED doc wanted to give transfer orders of Dilauded 1mg q2hrs PRN. It wasn't making any sense to me to keep doing the same thing over and expecting a different result so I asked the nurse to see about having it changed to 2mg q1hr PRN of which the doc did. Transfer was a little over 2hrs.
So about 15mins into the transfer after I get everything situated patient is still having 8/10 pain that is being exacerbated by the dynamics of the ambulance transport so I give the 2mg Dilauded slow IVP as ordered. Within 10mins pain is slightly reduced, pt. getting sleepy but alert and oriented, hard to hold eyes open.... I'm thinking okay patient had long night, the narc is making her want to sleep. 10-15mins later... highly somnolent, decreased orientation, desaturating, decreased B/P, slight perioral cyanosis developing = NOT GOOD.
I don't want to hit her hard with Narcan so I decided to give 0.2mg Narcan IV... nothing. 5mins later another 0.2 which results in full reversal. Patient is back to baseline mental status and level 9 pain.... ok.. this sucks!
So I call MedComm and explain the case to the doc (who is very cool during the consult) to see what direction she wanted me to go for pain management. Orders are given for 50mcg fentanyl q20-30mins PRN. Patient get's 100mcg over 90mins which brings pain to a level 7 and is tolerable with no adverse effects.
POINTS FOR DISCUSSION:
- I was really surprised that 2mg of Dilauded in a 500lb patient would have the profound and negative effect that it did on this patient. Especially considering that 1mg was barely even scratching the surface.
- Anyone else have any cases like with involving Dilauded?
- I am a strong advocate for pain management for my patients and feel I did the right thing.
- Any other input is appreciated !
