Every year, millions of Americans are able to experience a painless surgery with the help of anesthesia, even though most don’t really know how anesthesia works. Each day, Steel City Anesthesia helps administer anesthesia to Ambulatory Surgery Centers, and hospitals and doctors’ offices across Pennsylvania, Ohio, and West Virginia. Although it is extremely common and vital to the world of medicine, there is constant research to find out exactly how anesthesia works. The most common theory is that anesthetics block neural function by disrupting fat molecules in the cell membranes. However, new research from a study done by Weill Cornell Medicine may have debunked a century-old theory of how anesthesia works. Co-researcher Dr. Hugh Hemmings, chair of the Department of Anesthesiology at Weill Cornell Medicine, discusses the new findings saying they have debunked a century-old theory of how anesthesia works and, “Finally have proof that these anesthetics must have a direct effect on integral membrane proteins – and not an indirect effect on proteins through the lipid bilayer – to put patients in a coma-like state, allowing them to undergo painful procedures with no memory or pain.” This new evidence supports the idea that anesthesia does not affect the lipid bilayer, which is the part of the cell membrane that is made up of fat. The new findings show rather than interacting indirectly through the membrane itself, anesthetics interact directly with membrane proteins, which inhibit electrical communications between neurons, which triggers unconsciousness. Researchers in this study reconstructed a model cell surrounded by thin membrane in order to determine the biological mechanism behind anesthesia. Thirteen different anesthetic agents were tested using a technique developed by by Dr. Olaf Andersen, a professor of physiology and biophysics at Weill Cornell Medicine, and Dr. Helgi Ingólfsson, Ph.D. The results showed that none of the anesthetics tested affected the lipid bilayer properties. “That was a very surprising result,” said Dr. Andersen. “When we started conducting the experiments I was convinced we would see some effect on the bilayer. The fact that the results are as clean as they are was to me really amazing.” While there is still more research to be done on this topic, these results are groundbreaking in the world of anesthesia. Researchers are always hoping to learn more, and this study may have just “debunked” a century old theory of how anesthesia works. As we focus on patient care and achieving industry leading satisfaction ratings, having a better understanding of the mechanisms behind anesthesia can lead to the development of new anesthetic agents with less undesirable side effects.
Getting a colonoscopy? Are you worried about the procedure? Check out this informative and entertaining video on colonoscopies. We promise it will make you smile!
March is National Colorectal Cancer Awareness Month. Cancer of the colon or rectum is the second leading cause of cancer-related deaths in the US. It affects both men and women and is one of the most commonly diagnosed cancers in the US. Chances of developing colorectal cancer increase with age with more than 90% of cases occurring in people aged 50 or older. If you are age 50 or older, one of the best things you can do to protect yourself against colorectal cancer is get screened on a routine basis. It is estimated that 60% of colorectal cancer deaths could be prevented if individuals were screened routinely. These screenings detect colorectal cancer early, when treatment is most effective. Individuals that have a close relative that has had colorectal polyps or colorectal cancer, or those with inflammatory bowel disease should also consider getting tested earlier than age 50 and more often than others. There are several tests used to screen for colorectal cancer. One of the more popular and effective of these is the colonoscopy. It is a procedure used to see inside the colon and rectum for detection of inflamed tissue, ulcers and abnormal growths. A colonoscopy is recommended every 10 years. This is one of the most common procedures our experienced CRNAs at Steel City Anesthesia put patients under for. Your doctor will provide you a detailed set of instructions on how to prepare for a colonoscopy; this is called bowel prep. All solids must be emptied from the gastrointestinal tract followed by a clear liquid diet. This allows the physician conducting your colonoscopy to thoroughly examine your colon without any obstructions. Throughout the procedure, you will be under a sedative to keep you relaxed and as comfortable as possible. How Can You Support Colorectal Cancer Awareness? You can spread awareness by wearing a colon cancer ribbon. The colon cancer ribbon is a small piece of dark blue ribbon folded into a loop. By wearing a ribbon, you show your support for colon cancer patients that have fought the disease to return to a normal life. You also spread knowledge about colon cancer and how it can be prevented. If a ribbon isn’t your thing, there are also rubber bracelets, T-shirts, pins and other items you can wear. Learn more on the Colon Cancer Alliance website.
