Capsaicin Tested On Surgical Wounds

Posted by kdawson on Tue Oct 30, 2007 10:48 PM
from the that-smarts dept.
Ponca City, We Love You writes "Bite a hot pepper, and after the burn your tongue goes numb. The Baltimore Sun reports that Capsaicin, the chemical that gives chili peppers their fire, is being dripped directly into open wounds during highly painful operations, bathing surgically exposed nerves in a high enough dose to numb them for weeks. As a result patients suffer less pain and require fewer narcotic painkillers as they heal. 'We wanted to exploit this numbness,' says Dr. Eske Aasvang, a pain specialist who is testing the substance. Capsaicin works by binding to C fibers called TRPV1, the nerve endings responsible for long-lasting aching and throbbing pain. Experiments are under way involving several hundred patients undergoing various surgeries, including knee and hip replacements using an ultra-purified version of Capsaicin to avoid infection. Volunteers are under anesthesia so they don't feel the initial burn."

        If a Jalapeno hurts you then you better not eat a 'hot' pepper. On the Scoville scale a Jalapeno is only about 5000 scoville units. A Cayenne is about 30,000. A Habanero is rougly 350,000. And the new record holder is the Naga Jookla at around 1,000,000. Go eat a Naga and see how you feel afterwards, wimp. :)

            "As all hot pepper eaters should know, it's not the heat in the pepper, it's the juice".

            Actually this is not true. It is the Capsicain Oil that makes a pepper hot and not the 'juice' (which I take it you mean the watery part of a pepper). The saying that 'hurts going in hurts going out' (referring to going poopy) is pretty much true. But if you eat as much pepper extract as I do it hurts when you pee as well. I admit I take it to the extreme. I use Mad Dog 357 Collector's edition sauce with a 650,000 scoville rating at least 2 or 3 days a week (all meals for those days) and often poor WAY too much in it and think to myself..what the fuck did i just do?! However, even after the wonderfull pain I end up adding even more.

            1 lb of hamburger meat
            1.5 packets of Ortega Taco seasoning .5 packet of fajita seasoning
            1 full teaspoon of Mad Dog 357 Collector's edition

            Cook, eat and get ready for some insane heat and one of the most painful tinkles you ever dreamed of. =) Damn I love it HOT!!!

            Actually, it is the membranes that hold the seeds that contain most of the "heat".

            "Capsaicin (pronounced cap-SAY-iss-in) is a powerful chemical present in hot peppers that irritates certain nerves in the human nose and mouth. It is most highly concentrated in a hot pepper's central membrane, which holds the seeds."

              It was cheaper and faster to switch to prepackaged sauce versus the warmed-up sauce in the back (which frankly tasted better... not that Taco Bell is "good"). The preparers don't have to manage the sauce in the back any more and can crank out however many items they need faster.

      I had a mild case of Poison Oak this past summer. I wasn't getting any relief from the normal treatments, so I poured some Cayenne pepper powder on the rash. It almost immediately relieved the itching and the area felt cool. I think it also sped up the healing. The powder was too messy so I got some capsaicin cream that was intended for arthritis. It worked almost as well.

    they use a mix of anesthetic and the capsaicin so that you'r not in horrible pain. The nerves are over-stimulated in a way, this leads to them being numbed [like after eating too many spicy peppers] and it has already been used as a topical treatment for pain, I think there's even one pain treatment available to the public already based on this.

    Very interesting. I can say as a doctor I've never seen this used before though, but it reminded me of a few things:

    During surgery the patient is unconscious, and thus feels no pain, but good surgeons recognize that local anesthesia is still necessary. It's a bit counterintuitive, and I remember being puzzled back in medical school that the surgeons would still numb the area before doing any work despite the patient being unresponsive regardless. The thought is that nerves are damaged and there are changes / responses to the painful stimulus that persist despite the individual being unconscious; in a way, you still have neuronal pain signals if you don't give local anesthesia. It also prevents the patient from waking up with pain in the operative site before you can give other types of painkillers.

    Lidocaine (and capsaicin to some degree) would prevent the nerves from ever signaling -- they block the sodium channel that is necessary for nerves to fire. No firing -- no pain, *and* no no neuronal changes, and hopefully no long term pain. Lidocaine wears off after 2 hours or so, while it seems that capsaicin has much longer densitization effects.

    Of note, capsaicin is also used in "pepper spray" self-defense products advertised to women in particular. I wonder if one could become numb to this after repeated sprayings. Hmmm, anybody on slashdot may be able to answer this from experience? :)

      Speaking as an ex-law enforcement officer, I can say that there are numerous reports of frequent fliers (if you get my meaning) being relatively insensitive to the effects of being sprayed. Although I can't cite personal experience with such a phenomenon, that it was included in official training sessions suggests at least a modicum of truth. Rather more anecdotally, I've heard some officers claim that individuals who habitually consume large quantities of spicy foods are also less susceptible to the effects of OC spray, although the blinding/irritation effect seemed unchanged. I'm not sure I give much credence to the latter notion, however.

      cheers.

      Capsaicin mixed with a lidocaine derivative produced an anesthetic that affected only pain transmitting neurons, without affecting motor neurons. The lidocaine derivative was unable to penetrate nerve cells on its own, but the capsaicin opened pores that are only present in pain neurons.

      I can personally attest to the effects of the sichuan pepper, having eaten dishes made with this pepper in the Hubei region of China. I have enjoyed hot peppers of a variety of types in many of the foods I have eaten over time and consider myself to be a real lover of hot foods. The sichuan peppers really threw me for a loop though because they are the only peppers that have ever had a numbing effect on my mouth. Sure they are hot, but not noticeably hotter than alot of other peppers; but they have a slightly peculiar secondary flavor, and a strong numbing effect.

      The food in the Hubei province is really, really, REALLY good. Having travelled throughout many parts of China and enjoyed the diverse food in all the places I went, Hubei food was definitely at the top of my list. The sichuan peppers weren't the reason for that; they were OK but nothing special. It was the type of food, the zestiness of it, the really unique ingredients (beans in Chinese food? How weird!). There is a chain of Hubei food restaurants in Beijing called Jiu Tou Niau (not sure about the spelling there), which means "nine headed bird", and they are just awesome.

    Capsaicin is sold as ground chili pepper in capsule form at health stores, and seems to work very well at stimulating cardiac functions in general, as well as unclogging arteries in the long run. Plus, considering that it's natural, with none of the weird side effects that come with most pharmaceuticals, Capsaicin pills work as a supplement to standard medical treatments.

    I'm sure they'll find new properties of Capsaicin as time goes on. However, the corporate rub is that Capsaicin, like hemp, is a naturally occurring substance and therefore cannot be patented... unless (bite your tongue) they 'modify' the current laws.

      Nope, you haven't seen it before. That non-dupe is about a completely different anesthesia-related use of capsaicin. The purpose there is to enable the distribution of an anesthetic that only works from the inside into the cells.

      The purpose here is to give the nerve endings such an intense blast of pain that they go numb for days or weeks. This would be horrendously agonizing to the patient, but they're already under anesthetic and so don't notice it. Then, those nerve endings being numb for a few weeks reduces the need for post-surgery narcotics.
