Have you all been using multimodal anesthesia? If so, what? My current choices are listed below.

In pre-op holding:
  • Acetaminophen 975 mg PO
  • Celebrex 400 mg PO
  • Gabapentin 600 mg PO

At the start of anesthesia:
  • 50 mg/kg MgSO4 IV


On certain cases I will add 10 mg dexamethasone to the bupivacaine for the local.

Patients complained about nausea when I've used OxyContin pre-op so I stopped.

I think what's made the most noticeable drop in post-op pain has been the addition of the MgSO4. The last several bunionectomies, hallux rigidus repairs, and neuroma excisions have said they only took one or two opioids but had minimal pain.

What's been your experience?

Excellent question for a guy who works part time!! Seriously, anesthesia at the hosptial where I bring cases have suggested various protocols to reduce opioid use. However, I’m old school and have never had an issue with patients needing narcotics post operatively.

Yes, I do prescribe a limited amount of a narcotic post op, and in all my years of practice I renewed a narcotic RX once for a post op patient.

Many years ago, I noticed a few foot and ankle orthopedists patients seemed to have more post op pain than my patients or the other docs in the practice. Then I realized that most orthopedists do not use local blocks, but use general anesthesia and may inject some local before bandaging.

And THAT is the issue. Even if you are using general anesthesia in a case, ALWAYS inject the local before the incision. Yes, I know that sounds intuitive and basic but it’s a point that will make a huge difference in your post op patients.

The pain process begins at the incision. Performing a block after the procedure will result in significantly more post op pain, even if the surgery was under general.

Using a long acting local before the incision is paramount in limiting post op pain. The patient doesn’t experience that “breakthrough pain”.

Two factors often overlooked include surgical time and tissue handling. Over the years I became much more efficient with my movements in the OR. Without compromising quality, I was in and out quickly. I made sure everything I needed was up and ready and that the power equipment was functioning prior to tourniquet inflation. I also had minimal tension free retraction. Those two factors alone decrease post op pain. The shorter the tourniquet time the less pain patients experience. Overly tight or awkward dressings also contribute to post op pain.

Excluding any contra indications, I often give an injection of Toradol in recovery. I’m a huge believer in ice 20/min an hour when not contraindicated and also have patients take an NSAID (when not contraindicated) for 1-2 weeks. I know the bad press regarding NSAIDs and cardiac issues, and discuss this with the patient and PCP.

I believe strongly in this regimen and over the years kept a log regarding post op pain meds. 85% of my patients took less than 5 narcotic doses in the entire post op period and 90% of those 85% took 0-2 doses.

I only used in dwelling catheter anesthetic for heavy duty cases.

And I believe that patient confidence in their doctors makes a huge difference. I always assure patients NOT to expect a lot of pain and encourage them to call me at any time with any concerns. And I always call my post op patients within 24 hours to see how they are doing and reassure them I’m there if needed. When you reduce anxiety you reduce their concern of pain.

Although I always call within 24 hours (me, not my staff), in my opinion the most effective time to call is that evening. It makes the patient feel at ease and let’s the patient know you care.

This formula has worked for me for over 25 years, without any fancy or elaborate pre op or intra op or post op medication protocol.

Yep, it’s simple and it’s common sense. But it’s often overlooked.

Thanks for the lengthy response. I like your approach and I've done very similar for years.

I've found that adding the Dexamethasone to the Bupivacaine at the pre-incision local block extends anesthesia by several hours, but I don't use it when an osteotomy or arthrodesis is involved as I wouldn't want anyone pointing that direction were there to be a non-union.

Also, I stopped using post-op Toradol awhile back. About 12 or 13 years ago there was a local orthopedic case that resulted in patient death in which the use of Toradol was implicated. It made the local news so everyone in town was scared at the time and the surgeons stopped using it. Although it was a long time ago and patients have forgotten about it, I just never got back into the habit of ordering it.

A general surgeon turned me on to the mag sulfate. Before I started using it patients reported taking about 5-6 post-op pain pills but that quantity has dropped to almost none with the MgSO4. A few recent patients said they actually took zero pain pills and kept waiting for pain to occur but it never did. I've been pretty impressed. It's apparently a cheap drug and readily available.

I usually call the patient the next day since historically that's when they've been most likely to have issues but I like your idea of calling the same evening. Maybe I'll try that. Thanks again.

Calling that evening gives a comforting reassurance to the patient. It’s also an excellent way to reinforce the post op instructions to assure the patient starts doing things correctly immediately and not tomorrow. Remember, the patient is recovering from anesthesia and may not recall anything you said post op regarding instructions, how things went in the OR, etc.

The patients are always extremely grateful for the call.
 
Doesn’t dexamethasone near the surgical incision cause would healing problems?

Yes, it can. You only want to inject it mixed in with the local proximal to the surgery site, not around the incision.

You can also have anesthesia inject it via IV but it might prevent your patient from falling asleep (so they can lay awake thinking about whether or not their foot hurts — lovely). I had 8mg decadron IV once and didn’t sleep for two days!

Do you have a burner phone to call them from? Or a google voice number?
 
Always use a burner then destroy the card. That’s what they do in the movies.
 
If your hospital offers a regional anesthesia team you should consider using them. For my bigger cases ( ankle fusion, TTC, Triple, etc) i'll request a pop/saph ropiv on Q pain pump. These guys do great post op with pain. I still have a low dose cocktail (nsaid,norco) of medications ill give them post op, but for very very short duration. For more simple cases, a single shot pop/saph block does quite well. I don't mess with dex or any steroid injection pre or post op. Just haven't seen convincing evidence for it or for other things like magnesium, gaba, etc.

I prefer my surgery center to the hospital so there’s no anesthesia “team” per se but I’ve had the anesthesiologist to do a popliteal block. It does provide good anesthesia for the case.

After that general surgeon told me about the MgSO4 I found some literature then talked to a local anesthesiologist who does chronic pain medicine. Apparently it’s “a thing” in the anesthesia/pain management world. It was convincing enough for me to try it and like I said earlier it seems to have made a difference in my patients’ opioid use.

Thanks for your input.

In case anyone was looking for MgSO4 literature, here’s a start:

Magnesium: a versatile drug for anesthesiologists

[Effect of intra and postoperative magnesium sulphate infusion on postoperative pain]. - PubMed - NCBI

I use a shoe phone (you young guys probably don’t even remember the show “Get Smart”).

Depending on the patient, if I call after office hours, I often use the *67 feature to block my number. There are certain patients I trust not to abuse my cell number and I’ll give them that number. In all the years, no patient has taken advantage of having my number.

One caution about using *67. You have to let your patients know you may be calling and to answer the phone even if the caller ID says “blocked”. Most people are so tired of phone solicitations that they automatically ignore calls that say “blocked”.

I tell my patients this and it’s on my very specific post op instruction form the patient receives.

By the way, in my opinion that’s also an overlooked detail. Create your own very detailed post op instructions, and that alone will reinforce compliance and decrease the number of post op calls you receive.
 
Know a practice where the after hours office phone message gives out the docs cell phone number to post-op patients (though anyone that calls could get it just by listening)...and patients would call, and text, etc the doc at all hours. The only patient that has my cell phone number is a guy I operated on with a lot of land and a lot of hogs on said land. I would never let my office give out my cell and I wouldn't give every patient I operated on my cell either. That's the only reason I ask.
 
I never considered having a hog farmer exemption. I don't think I know any hog farmers though.

A few years ago one patient got my cell # and she'd text me random foot questions now and again. I had to put a stop to that.

I have several patients who were a friend first before they became a patient. A few of them will ask me questions via facebook so I have to tell them I can't reply or else the HIPAA cops will get me.
