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.
Diet. A few days before the colonoscopy. Start a eating a low-fiber: no whole grains, nuts, seeds, dried fruit, or raw fruits or vegetables. The day before the colonoscopy.Don't eat solid foods. Instead, consume only clear liquids like clear broth or bouillon, black coffee or tea, clear juice (apple, white grape), clear soft drinks or sports drinks, Jell-O, popsicles, etc.n the day before your colonoscopy â when you're restricted to clear liquids â you can have popsicles, Jell-O, clear broth, coffee or tea (without milk or creamer), soft drinks, Italian ice, or Gatorade. But take nothing with red, blue, or purple dye.
