Your patient has cirrhosis with well controlled ascites, HE, and unfortunately comes in with MSK back pain from raucously cheering in vain 4 the Winnipeg Jets.
They ask for advice/treatment. In addition to stretching/PT, you recommend...
This is prob ok in (short term) -ONLY IF they don’t have portal HTN
NSAIDs can
1. trigger diuretic resistance(fig1)
2. Provoke variceal bleed(fig2)
3. precipitate HRS(Throback2 )
So:🚫nsaids if ascites/varices

Patient: tylenol isn't cutting it. What else do you have for me?
Data:
1st, r they safe?
Fig1: Dame Sherlock gave morphine 2 ppl w/'impending HE' (BAD IDEA)
Fig2: But later study suggest NO EEG change s/p morphine
Fig3: Patwardhan showed that morph metabolism is PRESERVED in #cirrhosis

#Cirrhosis takes what u know about PK/PD & FLIPS THE SCRIPT (Fig1-2)
Think u know CYPP450? Wrong!
Each CYP varies w/stage, etiology, & the presence of cholestasis(Fig3)
How about glucuronidation? Jacked!(Fig4))

Don’t use opioids if you can avoid them. But sometimes u need em (e.g.fractures, hcc w/mets)
Start low/go slo. Choose med w/care.

Whenever I have used it, I found it led to resentment, encephalopathy, or both.
What's up?
Nothing better can be said about this drug that is variably converted 2 SNRI & opioid than was said by @DavidJuurlink:
Review articles suggest it. But what evidence is cited for its safety/efficacy?
There is one study
Ref: ncbi.nlm.nih.gov/pubmed/18557166
Fig1: Details about the pts enrolled are lacking
Fig2: W/o such data, the PK/PD data is 🤷♂️

The opioid effect of tramadol depends on CYP2D6
1. CYP2D6 activity varies widely @ baseline ascpt.onlinelibrary.wiley.com/doi/full/10.10…
2. 2D6 activity may ⬇️in ESLD (⬇️opioid effect, Fig1)
3. Then again, 2D6 may in⬆️HCC(Fig2)
Unpredictable @ getgo, ESLD makes it worse

👍Tylenol (2g/d)
👎🚫nsaids if ascites/varices
If u reach for an opioid: choose wisely, low/slo, 🚫constipation
Cirrhosis makes pain control challenging, but we cant shy away. We can all do better when managing pain for persons w/#cirrhosis

There's lots more to this topic of course but I hope it starts a productive conversation
Lots of opportunity to improve care for #livertwitter's allstars of PallCare (👀@nneka_ufere, @ArpanPatelMD)!
