Hot Chili Peppers to Tame Surgical Pain
The anticipated pain of surgery, and even post-operative pain is to maintain a large number of patients go for much needed treatment. Although anesthesia has been effective to keep a patient asleep, immobile, and pain during surgery — hardly complicated can avoid repeating the pain once the patient is awake.
Due to the limitations of anesthesia, medical and research community has been seeking a replacement or appropriate alternatives. Recently, scientists have conducted experiments on substances that are used to make hot sauce. Surgeons have tried to use the product chemical that makes chili peppers their "heat" as an experimental anesthetic directly pouring the substance into open wounds during knee replacement and a few other highly painful operations. The experiments made use of an ultra-purified version of capsaicin to avoid infection. The volunteers were under anesthesia so they do not feel the initial burn.
The treatment of surgically exposed nerves with a high dose of capsaicin was numb for weeks, so that patients suffer less pain and require fewer narcotic painkillers as they heal. According to Dr. Eske Aasvang, a pain specialist in Denmark who is testing the substance, "We wanted exploit this numbness. "
For centuries, hot peppers have been part of folk remedy and heat-inducing capsaicin creams are a cure for family pharmacy muscle spasms. Today, however, the species is also commercially "hot" because it shows how capsaicin pain research objectives detection key cells in a unique way. In addition to the California-based Anesiva Inc. 's attempt to harness that burn for more focused pain relief, Harvard University researchers also are mixing capsaicin with another anesthetic drug in hopes of developing epidurals that are not confined to women to bed during childbirth, or dental injections that do not numb the whole mouth. At the National Institutes of Health, scientists hope that by next year, which may begin the test in patients with advanced cancer, a variant of the capsaicin that is 1,000 times more powerful, to see if it can zap their intractable pain.
Nerve cells sense that a type of long-term throbbing pain contain a receptor called TRPV1. Capsaicin binds to this receptor and works to produce an analgesic in pain receiving specific fibers.
These so-called C neurons also sense heat, so capsaicin burn. But when TRPV1 opens, allows calcium further inside the cells until the nerves become overloaded and shut down. That's the numbness. "It just requires a new vision … stimulation of this receiver, in turn, the findings in a search for cellular therapy, "says Dr. Michael Iadarola NIH.
At a meeting of the American Society of Anesthesiologists, Aasvang reported that forty-one men were examined and underwent open hernia repair. Capsaicin recipients experienced significantly less pain during the first three days after surgery. Another U.S. study of 50 knee replacements, half were treated with capsaicin used less morphine in 48 hours surgery and experienced less pain for two weeks. Several ongoing studies that are experimenting with larger doses in more patients to see if the effect is real.
"There is a huge need for better postoperative pain relief," said Dr. Eugene Viscusi, director of acute pain management at the University Thomas Jefferson in Philadelphia, Pennsylvania, one of the test sites. "Morphine and its relatives, so-called opioid painkillers, surgery is expected. While Essential medicines are, have serious side effects that limit their use. "
