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.
Most colonoscopy preparation instructions donât tell you to follow a special diet two days before the exam. However, carefully choosing what you eat during this time can make the day before the exam a little easier. Two days before your colonoscopy, drink plenty of water and try to eat lightly. Avoid bulky, fibrous, sugary, and fatty foods such as: A lot of raw vegetables, beans, peas, and lentils. Wheat bran cereals and bread. Sweets such as cakes, pies, and cookies. Fatty meats such as fried chicken, sausage, and bacon.
