Background. Interscalene nerve block refers to the technique of anesthetizing the roots or trunks of the brachial plexus in the neck between the anterior and middle scalene muscles.The procedure was first well described and popularized by Alon Winnie in 1970.pence et al compared the effectiveness of an injection between the middle scalene muscle and brachial plexus sheath (periplexus) with an injection within the brachial plexus sheath (intraplexus) in 170 patients. There was no difference between the 2 groups in block onset times or block quality.
It's worth the hassle. Colonoscopy can spot small colon cancers while they are treatable and before they have spread to other parts of the body. It can also detect and remove polyps, small growths that can develop into colon cancer.
TWO-THREE Days BEFORE THE COLONOSCOPY - Do not eat beans, peas, corn, nuts, popcorn, okra, or tomatoes 2-3 days prior to your colonoscopy, as the seeds of these foods may adhere to the intestinal wall and may not flush out with bowel prep (start now if your colonoscopy is scheduled within the next 3 days).
