CLOSTRIDIAL MYOSITIS: NEVER GIVE A BANAMINE SHOT INTO THE MUSCLE


Monday, August 12th, 2013 | Filed under Medical




Many of us have seen this photo around FaceBook…

I’d like to expand on it a bit so we understand what the photo means.

Horse suffering from Clostridial Myositis:  gas gangrene.

Horse suffering from Clostridial Myositis: gas gangrene.

Basically, if you take the risk of giving a shot of Banamine into the muscle, you have the probability of infecting your horse with Clostridial Myositis – gas gangrene – which is most often fatal, FAST.

MALCOLM’S STORY

I found the original article about Malcolm and his battle with Clostridial Myositis (and the update) originally posted here.

HYPERBARIC CHAMBER

I did see that one treatment is a Hyperbaric Chamber.  I’m not sure why this wasn’t mentioned in the above articles… but I added a snippet here.  Good to know.

Clostridial Myositis and Myonecrosis (Gas Embolism)

      Clostridial myositis and myonecrosis is an acute, rapidly progressive infection of the soft tissues commonly known as “gas gangrene.”  The infection is caused by one of several bacteria in the group known as “clostridium.”  While over 150 species of clostridium have been identified, only a few commonly cause gas gangrene.  The infection typically spreads from a discrete focus of clostridium within the body.  The original source can actually be within the body, as clostridium normally live in the gastrointestinal tract.  Alternatively, the infection can originate outside the body, such as when infection results from contamination of wounds during trauma (e.g. motor vehicle accidents).

      Gas gangrene infection is severe and can advance quickly.  Besides replicating and migrating, the organisms which cause gas gangrene produce poisons known as exotoxins.  Exotoxins are capable of liquefying adjacent tissue and inhibiting local defense mechanisms which might normally contain a less virulent infection.  As such, the advancing infection of gas gangrene may simply destroy healthy tissue in its path and spread over the course of hours.

      Clostridium bacteria are “anaerobic,” meaning that they prefer low oxygen concentrations to grow.  If clostridium are exposed to high amounts of oxygen, their replication, migration, and exotoxin production can be inhibited.  This is the rationale for the use of hyperbaric oxygen in the treatment of gas gangrene.  Repeated treatment in the hyperbaric chamber has the potential to slow the progress of the infection while the two primary therapies, antibiotics and surgical resection of infected tissue, control it.

      The advantages of hyperbaric oxygen treatment in gas gangrene are two-fold.  First, it may be life-saving because exotoxin production is rapidly halted and less heroic surgery may be needed in gravely ill patients.  Second, it may be limb and tissue-saving, possibly preventing limb amputation that might otherwise be necessary.

    While a bacterial infection can occur following any intramuscular injection, it is particularly risky when injecting Banamine because it devitalizes the muscle tissue. Necrotic tissue is the perfect playground for bacteria because there is no blood supply to carry white blood cells to fight the infection. Irritating substances like Banamine should be injected intravenously instead.

    Read the information, yes it is rare and yes we have all given thousands of banamine shots IM but it DOES happen and it is truly awful and expensive! Despite clean needle, clean site, it happened. It only takes once for you to be cured, but why wait for that one time on your precious horse, find an alternative. Smugness might just bite you in the butt some day! FYI, many are saying to use the liquid orally, just be aware it is irritating and may cause mouth ulcers so if you need to use it more than once orally, go get the paste. If your horse quits eating after the IM Banamine is given orally, that might be why.

    I have give thousands banamine in the muscle never had anything happen until the other day I had this happen it was crazy I always heard this but never had anything close happen

    I agree that it’s not the banamine itself, but how the shot is given. My student had a horse that ended up with severe abscess in the neck and could’ve easily have had this happen because the prior owner, just a day before my student took the horse, gave him either banamine or another shot and our vet was sure it was that she didn’t use a clean needle/syringe etc. It isn’t the first time I’ve seen this happen. The other time a horse yanked away while being given the shot and ended up with infection/abscess also. So the key is to have a very experienced person giving the shots, always make sure to use a new/sterile needle, wash hands and clean the horses skin/hair beforehand, and if the horse is a nervous type about shots then do it another way(oral etc). I’m sure sometimes this is possible for this infection posted above to happen anyway and maybe a result of the drug used but probably very very rare and I’d say in general it is HOW the drug is administered not the drug itself. It’s common sense to be careful about giving your horse any shot. Take the time to really clean your stuff well and do what each individual horse needs. I have horses great with shots that I can do without my vet & I have some there’s no way I’d try to shoot them up with anything without out my vet present.

    Thanks for the info. It is important for us horse owners to keep upto date on the issues concerning horse health. I am greatful that there are people out there that are awear of issues. I didnot know until recently that injectable banamine can be given orally ( into the horses mouth without a needle ofcourse) with the same effect as an injection and might act quicker as the oral mucosa absorbs the med and send it to the painful area quickly.

    I think what most of the comments are not taking into consideration is that bacteria is an evolving organism. Therefore, what you may have done before and gotten away with may be changing now. Take care if you are doing your own shots and read up on it. It could save your horses life. Some of these bacteria, just like in humans, are coming on strong and in strange forms.

    OMG this is awful. I gave my Horse a Banamine shot last year inter-muscular for an undiagnosed condition. He ended up just fine, I would have been beside myself if this had occurred. Just knowing this can happen I will not do that EVER again. !!! Thanx for the Info!!!

    I am the proud owner of a miracle horse! He, as well as many of my other horses, have had many Banamine injections over the years. I love what Banamine does. So much that we put it in gel caps and take it for inflammation when WE need it. However, this past year, I have had troubles with Banamine reactions with my miracle horse. I got some swelling at the injection sites and some heavy sweating or perspiring, some of which were 6 to 8 inches in length and about 2 inches wide. It’s scared me enough that I have been avoiding giving him Banamine. Then I saw your all’s article and it has confirmed that I need to inject in the vein even though it says safe for intramuscular use. So that’s what I will do from now on if I need to use Banamine. It’s not worth it to take a chance on something this awful happening to this fantastic horse. Your FB page is very informative. Thank you for all the information!!

    my horse was given a shoot of Banamine into the muscle of her neck three months ago after she jumped the fence and got a Tpost in the chest and she did fine and she is still doing good …. i do not thank it is the Banamine in the muscle of the horse that is the problem here ! i have never seen this happen to any horses of mine or any that i know , I thank there is something more here that is not being said

  10. Jen

    I have given several I injections of banamine, both IM and IV. This has never happened to anyone I know or have heard of.

  11. Robin Churchill

    Clostridial myositis is caused by bacterial contamination not by specific drugs. It can occur with any injection or penetrating soft tissue injury for that matter. What people need to be careful about is the proper handling of injectable medications particularly multi-use vials.

  12. Rikki

    If it’s due to a bacteria, why is it linked to specific drugs? This does not make sense actually. It seems that if it’s a bacteria, it could happen to any formulation that is injected into the muscle, unless banamine and the other drugs mentioned inherently contact this specific bacteria, which is unlikely. What is the specific link to banamine? Just curious…

    We have always used penicillin for this and it worked great!
    Also many soldiers died from this during World War 1 prior to penicillin.

    I am going to visit her today… I do not know how she is other than ‘stable’. My vet, Dr.E was also on vacation last week so my updates
    were very sterile from the other technicians there. In short, I don’t know how she is…

  15. Dawn Stephens

    Dawn,

    Thanks for the informative article. I read your blog religiously every morning. However, I think we’ve been extraordinarily patient this last week (loved hearing about your trip to RLazyS – we’re planning a trip there ourselves now after reading your reports). I think I speak for all of us – How is Mama Tess? It made tears come to my eyes reading the repost of your Hubby’s blog and his description of MT in it. I do pray that she is doing better and that the lack of information is not due to bad news.

    Love from all of us at TinaJo’sPromise!

    Dawn, Tina Jo and Nathaniel

    I just gave my horse a Banamine shot in her neck muscle last week. :-( I did see this on FB, but didn’t know how prevalent it was. I am going to print this detailed info that you have provided to talk with my vet. Thanks!
