The brachial plexus at the interscalene level is seen lateral to the carotid artery, between the anterior and middle scalene muscles (Figures 2, 3, and 4). Prevertebral fascia, superficial cervical plexus and sternocleidomastoid muscle are seen superficial to the plexus.he goal of the continuous interscalene block is similar to the non-ultrasound-based techniques: to place the catheter in the vicinity of the trunks of the brachial plexus between the scalene muscles.
A colonoscopy is similar to a sigmoidoscopy, but a longer flexible viewing tube called a colonoscope is used to examine the entire colon and (if necessary) the lower portion of the small intestine. It is typically performed to detect colorectal cancer and to determine the causes of rectal bleeding, chronic diarrhea, chronic constipation, or abdominal pain.
A routine colonoscopy can save your life. Colonoscopy is one of the procedures used for prevention and early detection of colorectal cancer when it's most treatable. Colonoscopy is a diagnostic procedure that allows the physician to examine the entire large intestine.olorectal cancer is preventable. Colorectal cancer, cancers of the colon and rectum, is the third most common cancer diagnosed in both men and women in the United States. It strikes more than 140,000 Americans and kills about 50,000 every year. But early detection can make all the difference.
