GIT

  1. 1. Gastrointestinal Assessment<br />Physical Exam<br />1<br />
  2. 2. Health History and Clinical Manifestations<br />1. Complete history focusing on GI dysfunction.<br /><ul><li>Pain - major symptom of GI disease
  3. 3. Note the character, duration, pattern, frequency, location, distribution and time of the pain.
  4. 4. Aggravating factors – meals, rest, defecation, and vascular disorders may directly affect the pain
  5. 5. Indigestion - upper abdominal discomfort or distress associated with eating.
  6. 6. Most common symptom of patients with GI dysfunction.
  7. 7. Gastric peristaltic movements may or may not relieve the pain
  8. 8. Can result form disturbed nervous system control of the GI tract or elsewhere in the body
  9. 9. Fatty foods tend to cause discomfort as well as coarse vegetable and highly seasoned foods.</li></li></ul><li>
  10. 10. Health History and Clinical Manifestations<br /><ul><li>Intestinal gas – accumulation of gas in the GI tract.
  11. 11. May result to belching or flatulence
  12. 12. Complain of bloating, distention or being “full of gas”
  13. 13. Excessive flatulence – maybe symptom of gallbladder disease or food intolerance.
  14. 14. Nausea and vomiting - Another major symptom of GI disease.
  15. 15. Vomiting (emesis) is usually preceded by nausea
  16. 16. Can be triggered by odors, activity or food intake.
  17. 17. Vomitus may vary in color and content
  18. 18. May contain undigested food particles or blood (hematemesis)
  19. 19. When vomiting occurs soon after hemorrhage – bright red
  20. 20. If blood has been retained in the stomach – coffee-ground appearance because of digestive enzymes
  21. 21. Hematemesis – Vomiting of blood</li></li></ul><li>Health History and Clinical Manifestations<br /><ul><li>Changes in bowel habits – a signal of colon disease</li></ul>Diarrhea – abnormal increase in frequency and liquidity of the stool or daily stool weight or volume.<br /><ul><li>Occurs when contents move so rapidly through the intestine and colon with inadequate time for absorption of GI contents.
  22. 22. Sometimes associated with abdominal pain or cramping and nausea and vomiting</li></li></ul><li>Health History and Clinical Manifestations<br />Constipation – decrease in the frequency of stool or stools that are hard, dry and smaller volume than normal.<br />- May be associated with anal discomfort and rectal bleeding<br /><ul><li>Stool characteristics
  23. 23. Normally light to dark brown
  24. 24. Indigestion of certain foods and medications can change the appearance of stool.</li></li></ul><li>Foods and Medications That Alter Stool Color<br />COLOR<br />Dark brown<br />Green<br />Red<br />Dark red or brown<br />Yellow<br />Black<br />Milky white<br />ALTERING SUBSTANCES<br />Meat protein<br />Spinach<br />Carrots and beets<br />Cocoa<br />Senna<br />Bismuth,iron,licorice & charcoal<br />Barium <br />

  101. 101. ENDOSCOPIC PROCEDURESEGD<br />After the patient is sedated, the endoscope is lubricated with a water-soluble lubricant and passed smoothly and slowly along the back of the mouth and down into the esophagus.<br />Biopsy forceps to obtain tissue specimens or cytology brushes to obtain cells for microscopic study can be passed through the scope.<br />Patients may experience nausea, choking or gagging.<br />
  102. 102. ENDOSCOPIC PROCEDURESEGD<br />Use of oral anesthetics and moderate sedation makes it important to monitor and maintain the oral airway during the after the procedure.<br />Monitor oxygen saturation by means of pulse oximeters, and supplemental oxygen may be administered if necessary<br />
  103. 103. ENDOSCOPIC PROCEDURESEGD: Nursing Interventions<br />The patient should not eat or drink for 6 to 12 hours before the examination.<br />Help the patient spray or gargle with a local anesthetic.<br />Administer a sedative such as midazolam intravenously just before the scope is introduced.<br />The nurse may also administer atropine to decrease secretion, and glucagon to relax smooth muscle.<br />
  104. 104. ENDOSCOPIC PROCEDURESEGD: Nursing Interventions<br />Position the patient on the left side to facilitate saliva drainage and provide easy access for the endoscope.<br />Instruct the patient not to eat or drink until the gag reflex returns.<br />Place the patient in the Simms position until he or she is awake, and then place the patient in the semi-Fowler’s position until ready for discharge<br />
  105. 105. ENDOSCOPIC PROCEDURESEGD: Nursing Interventions<br />After gastroscopy, observe for signs of perforation: bleeding, unusual dysphagia, fever.<br />Monitor the pulse and blood pressure for changes that can occur with sedation.<br />Test the gag reflex. <br />Relieve minor throat discomfort by giving lozenges, saline gargle and oral analgesics<br />

  108. 108. Fiberoptic Colonoscopy<br />Usually performed while the patient is lying on the left side with the legs drawn up toward the chest.<br />Discomfort may result from instillation of air to expand the colon or from insertion and moving of the scope.<br />Potential complications include cardiac dysrhythmias and respiratory depression resulting from the medications administered, vasovagal reactions and circulatory overload or hypotension as a result of under- or over hydration.<br />
  109. 109. Fiberoptic Colonoscopy<br />Adequate colon cleansing provides optimal visualization and decreases the time needed for the procedure.<br />Patient should limit the intake of liquids for 24 to 72 hours before the examination.<br />Prescribe laxatives for two nights before the examination and a Fleet’s or saline enema until the return runs clear on the morning of the test.<br />Clear liquid diet starting at noon the day before the procedure.<br />
  110. 110. Fiberoptic Colonoscopy<br />Patient ingests lavage solutions orally at intervals over 3 to 4 hours.<br />Cardiopulmonary clearance prior to test for patients with known or suspected cardiac and pulmonary conditions, and in patients over the age of 40 years.<br />NSAIDs, aspirin, ticlopidine and pentoxifylline must be discontinued before the test and for 2 weeks after the procedure.<br />Informed consent must be obtained. <br />
  111. 111. Fiberoptic Colonoscopy<br />NPO after midnight before the test.<br />Monitor for changes in oxygen saturation, vital signs, color and temperature of the skin, level of consciousness, abdominal distention, vagal response and pain intensity during the test.<br />After the procedure, patients who were sedated are maintained on bed rest until fully alert.<br />Abdominal cramps are common as a result of increased peristalsis stimulated by air insufflated into the bowel during the procedure<br />
  112. 112. Fiberoptic Colonoscopy<br />Immediately after the procedure, observe the patient for signs and symptoms of bowel perforation.<br />If midazolam was used, the nurse should explain its amnesic effect; it is important to provide written instructions, because the patient may be unable to recall verbal information.<br />Instruct the patient to report any bleeding to the physician.<br />
  113. 113. Flexible Fiberoptic Sigmoidoscopy<br />
  114. 114. Anoscopy, Proctoscopy and Sigmoidoscopy<br />Visualize the lower portion of the colon to evaluate rectal bleeding, acute or chronic diarrhea, or change in bowel patterns, and to observe for ulceration, fissures, abscesses, tumors, polyps, or other pathologic processes.<br />Rigid or flexible fiberoptic scopes can be used.<br />Anoscopes are rigid scopes that are used to examine the anus and lower rectum.<br />Proctoscopes and sigmoidoscopes are rigid scopes used to inspect the rectum and sigmoid colon.<br />
  115. 115. Anoscopy, Proctoscopy and Sigmoidoscopy<br />For rigid scopes, the patient assumes the knee-chest position at the edge of the bed or examining table.<br />Keep the patient informed about the progress of the examination and to explain that the pressure exerted by the instrument will create the urge to have bowel movement.<br />
  116. 116. Anoscopy, Proctoscopy and Sigmoidoscopy<br />For flexible scope procedures, the patient assumes a comfortable position on the left side, with the right leg bent and placed amteriorly.<br />It is important to keep the patient informed throughout the examination and to explain the sensations associated with the examination.<br />These examinations require only limited bowel preparation, including a warm tap water or Fleet’s enema until returns are clear.<br />
  117. 117. Anoscopy, Proctoscopy and Sigmoidoscopy<br />Dietary restrictions usually are not necessary, and sedation usually is not required.<br />Monitor the vital signs, skin color and temperature, pain tolerance and vagal response during the procedure.<br />After the procedure, the nurse monitors the patient for rectal bleeding and signs of intestinal perforation.<br />On completion of the examination, the patient can resume regular activities and dietary practices.<br />

  155. 155. GASTRIC GAVAGE: Nursing Intervention<br />Feeding Methods:<br />Gravity<br />Drip-regulated (a Murphy drip is connected by tubing to a receptacle or Kelly flask) which hangs on an IV pole.<br />Motor pump<br />
  156. 156. GASTRIC GAVAGE: Nursing Intervention<br />Continuous Nursing Assessment<br />Recognize that even though nutritional deficits are corrected, some other problems may arise.<br />Cleanse all containers and tubings thoroughly.<br />Aspirate the tubing prior to feeding to verify that the tube is inside the patient’s stomach.<br />Avoid air bubbles in the system.<br />Provide oral and nasal hygiene before and after orogastric and nasogastric feedings for comfort or prevent infection.<br />
  157. 157. GASTRIC GAVAGE: Nursing Intervention<br />Continuous Nursing Assessment<br />Follow each feeding with water to flush tubing for cleansing and to promote fluid balance.<br />Monitor patient for signs of fluid and electrolyte imbalance.<br />Record amount of feeding and water; indicate patient’s participation and acceptance.<br />
  158. 158. GASTRIC GAVAGE: Nursing Intervention<br />Patient Education<br />Since tube should be changed every 2 to 3 days, the patient may be taught how to do it.<br />The patient should learn how to feed himself.<br />Skin requires special care.<br />

  191. 191. The ABDOMINAL examination<br />The sequence to follow is:<br />Inspection<br />Auscultation<br />Percussion<br />Palpation<br />103<br />
  192. 192. Most Common GIT Symptom<br />Abdominal Pain<br />Major symptom of GI disease.<br />Character<br />Duration<br />Pattern<br />Frequency<br />Location<br />Distribution of referred pain<br />Time of the pain<br />Is it?<br />Medical Abdomen?<br />Surgical Abdomen?<br />When to refer?<br />104<br />
  193. 193. Indigestion<br />Upper abdominal discomfort or distress associated with eating.<br />Most common symptom of patients with GI dysfunction.<br />Fatty foods tend to cause the most discomfort.<br />Coarse vegetables and highly seasoned foods can also cause considerable distress.<br />105<br />
  194. 194. Intestinal Gas<br />The accumulation of gas in the GIT may result in belching or flatulence.<br />Patients often complain of bloating, distention, or “being full of gas.”<br />106<br />
  195. 195. Nausea and Vomiting<br />Vomiting is usually preceded by nausea, which can be triggered by odors, activity, or food intake.<br />Emesis, or vomitus, may vary in color and content.<br />Hematemesis refers to bloody vomitus.<br />107<br />
  196. 196. Change in Bowel Habits and Stool Characteristics<br />These may signal colon disease.<br />Diarrhea (abnormal increase in the frequency and liquidity of the stool or in daily stool weight or volume) occurs when the contents move so rapidly through the intestine and colon.<br />Constipation (decrease in the frequency of stool, or stools that are hard, dry, and of smaller volume than normal) may be associated with anal discomfort and rectal bleeding.<br />108<br />
  197. 197. Change in Bowel Habits and Stool Characteristics<br />Stool is normally light to dark brown.<br />Ingestion of certain foods and medications, as well as the presence of blood, can change the appearance of stool.<br />Bulky, greasy, foamy stools that are foul in odor; stool color is gray with a silvery sheen (fat malabsorption).<br />Light gray or clay-colored stool (absence of urobilin).<br />Mucus threads or pus in stools (infection).<br />109<br />
  198. 198. Change in Bowel Habits and Stool Characteristics<br />Scybala (small, dry, rock-hard masses) often seen in narrowing of the colonic lumen.<br />Loose, watery stool that may or may not be streaked with blood (inflammatory conditions).<br />110<br />
  199. 199. PHYSICAL ASSESSMENT<br />Assessment of the mouth, abdomen and rectum.<br />Mouth, tongue, buccal mucosa, teeth and gums are inspected, and ulcers, nodules, swelling, discoloration, and inflammation are noted.<br />Patients with dentures should remove them during this part of the examination to allow good visualization.<br />111<br />
  200. 200. PHYSICAL ASSESSMENT: The Abdomen<br />Patient lies supine with knees flexed slightly for inspection, auscultation, palpation and percussion.<br />The nurse performs inspection first, noting skin changes and scars from previous surgery.<br />It is also important to note the contour and symmetry of the abdomen, to identify any localized bulging, distention, or peristaltic waves.<br />112<br />
  201. 201. Abdominal Assessment: Auscultation<br />Character, location and frequency of bowel sounds.<br />Assess bowel sounds in all four quadrants using the diaphragm of the stethoscope.<br />Categorize and document frequency of bowel sounds into normal (5 to 6/min), hypoactive (1 sound/min), hyperactive (5 to 6 sounds in less than 30 seconds), or absent (no sound in 3 to 5 minutes).<br />113<br />
  202. 202. Abdominal Assessment: Percussion and Palpation<br />Tympany or dullness.<br />Light palpation for identifying areas of tenderness or swelling.<br />Deep palpation to identify masses in all four quadrants.<br />If any area of discomfort is identified, the nurse can assess for rebound tenderness.<br />114<br />
