A Test To Check The Large Intestine Biology Essay


Barium enema, or better known (GI) examination, is a test to check the large intestine (colon and rectum). The test is used to help diagnose diseases and other problems affecting the large intestine. To view the large intestine is filled with contrast material containing barium. It can highlight specific areas on the desired section and produce a clearer image. This test is done by inserting a contrast material through the tube into the anus. Barium will be out of the body with the stool. Enema Division is divided into 2 types, single and double Contras, or water Contras.

Double contrast or air contrast is the result of a combination of barium and air used to clean the colon wall that is seen clearly in the radiograph. It is also used to display the mucosal pattern is more detailed and more sensitive to detect polips and inflammatory bowel disease. Single contrast barium sulphate which is inserted into the rectum to obtain images of the large intestine is a technique often used for colon obstruction, acute diverticulitis, acute apendicitis or fistula.

In some cases, a single contrast studies may be used for certain medical reasons or for older patients who can not take a long time, but if the result is not satisfactory double contrast examination will be conducted.

Information that should be taken for identification purposes for the barium examination of the films.

- The name of the patient.

- In order to determine the correct sequence according to the following positions.

Early preparation

patients with early preparation to provide the abdomen, which can be given and the description of the intestine to facilitate detecting stones or tumors. This requires early detection studies (radiographic image) was taken after a colon cleansing before receiving the contrast media. This is to prevent scarring or wound in the intestines and colon that are sure to be tested completely clean. Patients should also be given early information about the procedure for patients can be prepared in advance and radiation tests can be conducted smoothly. Make sure the patient's medical history review, aims to ensure free patients undergoing intestinal surgery around the room. As an interpreter of x-ray, is a duty to remind the patient to fast for 8-9 hours before the procedure. Quantity of food intake in low-and high-fiber is allowed to prevent and reduce excessive gas due to the digestion process is also entitled to be supplied makanan.Pesakit saline enema / laxative (bowel drug) and instructed to eat the day before testing to remove all air and digestion / feces in the intestines and digestive organs and intestinal facilitate image can be seen clearly. Some interpreters x-ray of the opinion that smoking and chewing gum can stimulate the secretion of gastric fluids and saliva. Therefore, patients were also asked to stop smoking and chewing gum to prevent excess fluid from gathering in the stomach and the thicker barium sulfate.

- Has tests for barium digestion. Preparation barium enema usually involves cleaning the colon with very carefully because of the large intestine must be completely clean of dirt and impurities or gas . small gas may affect the accuracy of the test.

    A radiograph taken (prelim PA abdomen) is taken to assess the early stages of patient preparation, exposure and anatomical structures. The patient lay with both legs at the knee in flexion. Catheter was inserted into the rectum and attached with adhesive tape and connected to the equipment to include barium. IV Buscopan @ glucagon injections done. Fluroscopy done to see Barium. Patients lay in the position (supine). Barium added slowly, until the infusion is discontinued when the flexure spleenik. Strontium barium liquid is released. Generated air into the rectum to yield double-contrast images. Turning the patient's body from left to 'right anterior oblique' (RAO) to barium coating the mucosal wall.

Radiation protection:

      Ensure that patients are not pregnant and cut the power at fluoroscopy. Collimation is required to enter the area only to the radiation field. Using the image of a modern observer is more sensitive, (eg CSI) photocathodes and digital image processing is also using video recorders to replace cine camera during fluoroscopy, if possible. Implementing QA programs to optimize the performance of staff and equipment. Provide protection and give gonad explanations about the procedure to the patient, the patient can cooperate, then screening may be done without the need to be repeated many times.

Specific care should be given to patients in the following circumstances:

• Structure / refinements:

- Provide oversight of reflux occurred, and enter the respiratory tract.

• blockage / obstruction:

- Monitor the rate of admission to Barium Barium is not abundant in the respiratory tract.

• Fistula (opening between the anal canal and the skin that may develop in the rectum after the abscess had burst):

- Watch the fistula if there is any output from the fistula causes artifacts in the image.

• Diabetes (diabetes mellitus):

- Make sure that the normal kidney patients because if there is kidney failure, the possibility of barium can not excrete properly.

• Leaking anastomosis:

- Use of Gastrografin barium as possible going into the lungs and blocks breathing.

• Infants and children:

- Keep the movement ban will be because of the possibility of patient motion.

- The screening time must be limited to avoid moving the patient.

- The volume of barium must be correct based on the rate of children or infants.
