Intrathecal Pain Pump

Posted by duckski44 @duckski44, Jun 21 5:02pm

I’ve have an intrathecal pain pump for many years, just trying to connect with others that have this device to chat with people about effectiveness and drug therapies.

@heisenberg34 I’ve had the pump for 8 years and just had it replaced with the 40ml unit. The Medtronic rep at my first implant didn’t have any 40’s, so I got a 20. And monthly refill trips. My trial was with morphine. After the 6 week dry out. She injected 250 mcg. (A 1/4 of a milligram!) within minutes, I was dancing in the hallway with my cane like Gene Kelly singing in the rain. The trial dropped my pain from a 9 to a 1 ! When I went for my first refill it was 275 mcg. And that wore off pretty fast. 8 years later, I’m on 12.1 mg./day. Four 2.5 bolus’s and 1.97 continuous. I went from 8 to 6. How I long for a level 4. My first doc was very conservative and it took over 18 months to be titrated properly. I have a high tolerance for morphine and pain. But my 6 turns to a 7+ at night and a strong 8 on rainy days with a low pressure barometer. At the time I got it, hydromorphone was not acceptable in a pump. But at 40x the strength of morphine I’m going to ask my doctor to plan on switching meds. The best part for me is now I have a full 2 months between refills! And I’m in PT which has to hurt before it helps. If he won’t change to the Dilaudid then it’s another 15% increase in 6 months. Unfortunately I live in the MS/TN border and all health care is in Memphis and it’s awful.

@bilt4pain That’s great information. I wish I had done more research prior to getting the trial. I would have asked all those important questions regarding how much I was getting. I was on the verge of getting the pump removed until I started looking into all those amounts. That was when I discovered how low I was even after sixteen months. So, going up again. Not sure what my current level is. At my last refill, the nurse told me that I was at about 1.9 mg. I guess that’s per day. I’ve had it increased by ten percent and fifteen percent a few times so I don’t know where I am currently.
I have seen others on this site way up there, so I’m not too worried about going higher. I guess I’m fortunate to be able to get my output adjusted every two to four weeks.
Let’s try and keep each other updated if I can remember. lol. Thanks again!

I’m curious, which joint was replaced 7 times? I’ve had my L hip replaced 7 times due to dislocation issues and muscular instability, the final result is a stable joint now, but terrible muscle pain issues, my pump is maxed out with dilaudid, so my Dr also gives me oral dilaudid which makes life tolerable.

I had 7 different joints done. Neck front and back, lumbar spine, both knees and both hips and the grand finale right shoulder replacement. Whew!

1.9 X 24 hours = this would be your daily dose.
You are still at a fairly low dose per day.

Do pain pumps cause weight gain? With a pain pump, is there any feeling like you've just taken a pill, like a warm hug? I mean does it go to your head at all?

REPLY

How does it make your head feel? How large is incision to implant pump? If you don't mind, of course.

@dasunbehagen The medication is delivered into the intrathecal space around the spinal cord. Literature states that the med does not pass the blood/brain barrier (it doesn't go into the general body systems), so no real side effects. I have not experienced any weight gain. Most pumps are implanted inside the abdomen just under the skin. This is so the port can be easily accessed for refilling(about every two to three months). The pump is about the size of a hockey puck, so a small incision 1-2" is made on your front, side abdomen. Tubing is fished around to your back where a small incision is made in order to place a catheter(needle) into the spinal canal and then attached to the tubing. Hope that answers your questions.

Archie here:

When I first had my pump implanted in 2007 in DC, I also had an infection which resolved into a large seroma (fluid filled sack) around the pump. The surgeon was apologetic as he removed many 100.s of cc's from my body., but it solved the issue. I'm now 80, and my Adhesive Arachnoiditis has progressed and for whatever reason is more active right now. I have a 40ML PUMP, SO PLENTY OF ROOM FOR MEDICATION. I get over 6.8 on continuous flow daily (I'll look ups exactly if you need it) but also have the choice of 5 boluses /day. This flexibility precludes the necessity of oral meds. Bottom line, I'm very happy with the Medtronic 40 that I have.

As an aside, I recently had a consult with the head of Neurology at Mayo's in Jacksonville, and he told me again the AA is progressive and that it was UNREASONABLE for me to expect the pump to cover all the pain issues I am having, That was a real kick in the butt, and he recommended getting a spinal cord stimulator as an adjunct to the pump. For me, that has been a big mistake. I've gone through months of healing, testing various treatment protocols--all to no avail--it just doesn't help me. So be aware that it may not be for everyone. I've had AA since 1978, so I do have some perspective on the disease and treatment modalities.. I wish you good luck.
Best, Archie

@archie2 I have a spinal cord stimulator since 2021. It worked for about a year and then stopped. I think the problem was that my stimulator moved. It is now sticking out of my back instead of being flat against my back. I am now looking at a pain pump. The first trial was unsuccessful. It took many hours for the medication to work, but I still had to take OxyContin that night. I will be having another pain pump trial in the near future and I’m hoping it will work better. In other words I would give the stimulator a chance.

@ukdebcat Sounds a lot like my experiences. My SCS lasted about two and a half years before it also just stopped one day. No warning. Tried another, different battery. No luck. Two years later I had my pain pump trials. Both were done by injection. First one used morphine. No help. Two weeks later they injected hydromorphone(Dilaudid). Within ten minutes it dropped my pain from an eight down to about a two. It was great. Two and a half years later I am still in the process of having it adjusted. Initially I had it increased, but after about a year I stopped and considered having it removed. But, after some research and with help from the great commenters here on Mayo Clinic Connect, I discovered that I was still at a relatively low amount. So, I began having it increased again. Except for ONE DAY(!) I have not gotten any pain relief, so "Up< Up, and Away" for now. I will certainly keep everyone in the loop. My daily total output is 1.75 mg. Good day and God's blessings to you all!

I have had Medtronic pump, it was first implanted in 2012. I used the smallest dose available and in 13 years have had 3 minor bump ups (increased dose). In 2026, I will receive a new pump and have been totally satisfied with its performance, without I can barely get out of bed. I have had 7 joint replacements, but the pump is for failed back surgery of my lumbar spine. I was in the care of a neurosurgeon who rebuilt my neck and attempted to repair my lumbar spine. I have DDD and every disk is affected by arthritis, as well as all my joints. A friend of mine afflicted with rheumatoid arthritis similar to my condition and I say you don't make the decision is made by your pain. If you've tried every other treatment to no avail, what have you got to lose? Sometimes there are no "cards' left in the deck. Good luck to all seeking relief.

@morkat I just came across your post regarding your pain pump. Looks like you are pretty happy with it. I've been trying to get relief from mine for over two years. Can you tell me what your total, daily output is? Also, do you have any boluses? Do you use them? Thanks for sharing. I apologize if I have reached out before and just forgot.

Don't apologize I get sidetracked so easily I understand. I have to find my folder and I can answer your questions then, okay?
