CTZ, Chemoreceptor trigger zone; GI, gastrointestinal. Clinical Manifestations • Nausea – Subjective complaint – Usually accompanied by anorexia • Vomiting – Dehydration can rapidly occur when prolonged. – Water and essential electrolytes are lost. – Metabolic alkalosis—from loss of gastric HCl – Metabolic acidosis—from loss of bicarbonate if the contents from the small intestine are vomited Collaborative Care • Differentiate among vomiting, regurgitation, and projectile vomiting • Regurgitation – Partially digested food slowly brought up into stomach • Projectile vomiting – Forceful expulsion of stomach contents without nausea • Fecal odor and bile indicate a lower intestinal obstruction. • Color of emesis aids in determining presence and source, if bleeding. Collaborative Care • Drug therapy – Antiemetics act on CNS to block chemicals that trigger nausea and vomiting. – Examples • Anticholinergics – Scopolamine transdermal (Transderm-Scop) • Antihistamines – – – – Dimenhydrinate (Dramamine) Promethazine (Phenergan) Meclizine (Antivert) Hydroxyzine (Vistaril) • Phenothiazines – Prochlorperazine (Compazine) • Chlorpromazine (Thorazine) – Common side effects include • • • • • Dry mouth Hypotension Sedative effects Rashes GI disturbances Esophageal Disorders • Gastroesophageal reflux disease (GERD) (discussed in another PowerPoint) • • • • • • Hiatal hernia Esophageal cancer Esophageal diverticula Esophageal strictures Achalasia Esophageal varices Gastroesophageal reflux disease (GERD) Description • Not a disease but a syndrome, secondary to reflux of gastric contents into lower esophagus Etiology and Pathophysiology Esophagitis with esophageal ulcerations. Etiology and Pathophysiology • Predisposing factors – Hiatal hernia – Incompetent lower esophageal sphincter (LES) • Antireflux barrier – Decreased esophageal clearance – Decreased gastric emptying • HCl acid and pepsin secretions reflux—cause irritation and inflammation • Intestinal proteolytic enzymes and bile salts add to irritation. – Primary factor in GERD • • • • • • • Results in ↓ in pressure in distal portion of esophagus Gastric contents move from stomach to esophagus. Can be due to certain foods (caffeine, chocolate) and drugs (anticholinergics) Obesity is a risk factor. Pregnant women are at increased risk. Cigarette and cigar smoking can contribute to GERD. Hiatal hernia is a common cause of GERD. Clinical Manifestations • Symptoms of GERD – Heartburn (pyrosis) • Most common clinical manifestation • Burning, tight sensation felt beneath the lower sternum and spreading upward to throat or jaw • Felt intermittently • Relieved by milk, alkaline substances, or water – Dyspepsia • Pain or discomfort centered in upper abdomen – Hypersalivation – Noncardiac chest pain • More common in older adults Clinical Manifestations • Most individuals have mild symptoms. – Heartburn after a meal – Occurs once a week – No evidence of mucosal damage • Individual may also report – – – – – – – – Wheezing Coughing Dyspnea Hoarseness Sore throat Lump in throat Choking Regurgitation Clinical Manifestations • Regurgitation – Effortless return of food or gastric contents from stomach into esophagus or mouth – Described as hot, bitter, or sour liquid coming into the mouth or throat – Can mimic angina • Related to direct local effects of gastric acid on esophageal mucosa – Esophagitis • • • • Inflammation of esophagus Frequent complication Other risk factors include hiatal hernia, chemical irritation.

Etiology and Pathophysiology • The longer the passage of blood through intestines, the darker the stool color caused by breakdown of Hb—release of iron • Cause of bleeding is not always easy to determine. – Variety of areas in GI tract may be involved. Nursing Management • Nursing assessment – LOC – VS • Orthostatic • Every 15 to 30 minutes – – – – – Appearance of neck veins Skin color Capillary refill Abdominal distention, guarding, peristalsis Signs/symptoms of shock • • • • • Low BP Rapid, weak pulse Increased thirst Cold, clammy skin Restlessness Nursing Management • Nursing diagnoses – Deficient fluid volume – Ineffective tissue perfusion – Anxiety – Ineffective coping – Risk for aspiration – Decreased cardiac output Nursing Management • Planning: Overall goals – No further GI bleeding – Cause of the bleeding identified and treated – Return to normal hemodynamic state – Minimal or no symptoms of pain or anxiety Nursing Management • Health promotion – Patient with a history of chronic gastritis or peptic ulcer disease is at high risk. – Patient who has had one major bleeding episode is more likely to have another. – Patient with cirrhosis or previous UGI bleed is also at high risk. – Nurse education • Disease process and drug therapy • Avoidance of gastric irritants – Alcohol – Smoking – Prevent or decrease stress-inducing situations. • Take only prescribed medications. • Methods of testing vomitus/stools for occult blood – Patient teaching • Potential adverse effects related to GI bleeding • Prompt treatment of upper respiratory infection in patient with esophageal varices • If aspirin must be prescribed, enteric-coated tablets can be substituted for regular tablets. • Taking the medications with meals or snacks lessens the potential irritating effects. Nursing Management • Acute intervention – – – – – Approach in calm, assured manner to decrease anxiety. Use caution when administering sedatives for restlessness. Warning sign of shock may be masked by drugs. IV maintenance Accurate I/O record • • • – Urine output hourly At least 0.5 mL/kg/hr indicates adequate renal perfusion. Urine-specific gravity should be measured.

Gradual introduction of food follows as tolerated – Monitor laboratory studies. • • Hb and Hct every 4 to 6 hours BUN assessed – Oxygen management Nursing Management • Ambulatory and home care – Patient teaching • Patient/family taught how to avoid future bleeding episodes • Made aware of consequences of noncompliance with diet and drug therapy • Emphasis that no drugs other than those prescribed should be taken • No smoking, alcohol • Need for long-term follow-up care • Instruction if an acute hemorrhage occurs in future Nursing Management • Evaluation – Have no further GI bleeding – Maintain normal fluid volume – Experience return to normal hemodynamic state – Experience absence of or tolerable levels of pain and be comfortable – Understand potential etiologic factors, and make appropriate lifestyle modifications Audience Response Question When teaching a patient with a history of upper GI bleeding to check the stools for blood, the nurse informs the patient that: 1. If vomiting of bright red blood occurs, stools will not be black and sticky. 2. Blood is never obvious in stools and must be detected by fecal occult blood testing. 3. Acute bleeding in the upper GI tract will result in bright red blood in the stools. 4. Stools that are black and tarry occur with prolonged bleeding from the stomach or small intestine. Peptic Ulcer Disease • Erosion of GI mucosa resulting from digestive action of HCl acid and pepsin • Ulcer development can occur in – Lower esophagus – Stomach – Duodenum Peptic Ulcers Peptic ulcers, including an erosion, an acute ulcer, and a chronic ulcer. Both the acute ulcer and the chronic ulcer may penetrate the entire wall of the stomach. Peptic Ulcer of the Duodenum Etiology and Pathophysiology • Develops only in the presence of an acid environment • Excess of gastric acid not necessary for ulcer development • Pepsinogen is activated to pepsin in presence of HCl acid and at pH of 2 to 3. • Stomach normally protected from auto digestion by gastric mucosal barrier • Surface mucosa of stomach is renewed about every 3 days. Mucosa can continually repair itself, except in extreme instances. • Water, electrolytes, and water-soluble substances can pass through barrier. • Mucosal barrier prevents back diffusion of acid and pepsin from gastric lumen through mucosal layers to underlying tissue. • Mucosal barrier can be impaired, and back diffusion can occur. – Cellular destruction and inflammation occur. – Release of histamine • Vasodilation • Increased capillary permeability • Secretion of acid and pepsin Etiology and Pathophysiology • Destroyers of mucosal barrier – Helicobacter pylori • Produces enzyme urease – Mediates inflammation, making mucosa more vulnerable – Aspirin and NSAIDs • Inhibit syntheses of prostaglandins – Cause abnormal permeability – Corticosteroids • ↓ rate of mucosal cell renewal – ↓ protective effects – Lifestyle factors • Alcohol, coffee, smoking, psychologic stress Clinical Manifestations • Pain high in epigastrium • 1 to 2 hours after meals • “Burning” or “gaseous” • Food aggravates pain as ulcer has eroded through gastric mucosa. • Duodenal ulcer pain • • • • • Midepigastric region beneath xiphoid process Back pain—if located in posterior aspect 2 to 5 hours after meals “Burning” or “cramplike” Tendency to occur, then disappear, then occur again Complications • Three major complications include – Hemorrhage – Perforation – Gastric outlet obstruction • All considered emergency situations Complication of peptic ulcer disease Perforation develops from erosion of – Granulation tissue found at base of ulcer during healing – Ulcer through a major blood vessel – Sudden, dramatic onset – Severe upper abdominal pain spreads throughout abdomen. – Tachycardia, weak pulse – Rigid, board-like abdominal muscles – Shallow, rapid respirations – Bowel sounds absent – Nausea/vomiting – Bacterial peritonitis may occur within 6 to 12 hours. – Difficult to determine from symptoms alone if gastric or duodenal ulcer has perforated Gastric Outlet Obstruction • Predisposition to gastric outlet obstruction includes – Ulcers located in • Antrum and prepyloric and pyloric areas of stomach • Duodenum – – – – – Edema Inflammation Pylorospasm Fibrous scar tissue formation All contribute to narrowing of pylorus. Gastric Outlet Obstruction • Early phase: Gastric emptying normal • Over time, ↑ contractile force needed to empty stomach – Hypertrophy of stomach wall • After long-standing obstruction – Stomach dilates and becomes atonic. • Clinical manifestations – Usually long history of ulcer pain – Pain progresses to generalized upper abdominal discomfort. Gastric Outlet Obstruction • Clinical manifestations (cont’d) – Pain worsens toward end of day as stomach fills and dilates. – Relief obtained by belching or vomiting – Vomiting is common. – Constipation is a common complaint. • Dehydration, lack of roughage in diet – – – – Swelling in stomach and upper abdomen Loud peristalsis Visible peristaltic waves If stomach grossly dilated, may be palpable Collaborative Care • Medical regimen consists of – – – – – – – – – • Adequate rest Dietary modification Drug therapy Elimination of smoking and alcohol Long-term follow-up care Stress management Aim of treatment program Reduce degree of gastric acidity Enhance mucosal defense mechanisms Generally treated in ambulatory care clinics – Ulcer healing requires many weeks of therapy. – Pain disappears after 3 to 6 days. • Complete healing may take 3 to 9 weeks. – Should be assessed by means of x-rays or endoscopic examination • • Aspirin and nonselective NSAIDs may be stopped. Smoking cessation Drug Therapy H2R blockers. Ex: Cimetidine, Ranitidine ,Famotidine PPIs proton pump inhib. Ex: Esomeprazole,Omeprazole Antibiotics. Ex: Ranitidine bismuth citrate (Tritec) with clarithromycin (Biaxin) Antacids . Ex:Effects on empty stomach 20 to 30 minutes; If taken after meals, may last 3 to 4 hours Therapy Related to Complications • Perforation – Immediate focus: • Stop spillage of gastric or duodenal contents into peritoneal cavity. • Restore blood volume. – NG tube is placed into stomach. • Continuous aspiration • Placement of tube near to perforation site facilitates decompression. – Circulating blood volume: Replaced with lactated Ringer’s and albumin solutions • Blood replacement in form of packed RBCs may be necessary. Central venous pressure line inserted and monitored hourly • Indwelling urinary catheter inserted and monitored hourly • ECG—if history of cardiac disease – Broad-spectrum antibiotics – Pain medication – Open or laparoscopic repair Therapy Related to Complications • Gastric outlet obstruction – – – – – Decompress stomach. Correct any existing fluid and electrolyte imbalances. Improve patient’s general state of health. NG tube inserted in stomach, attached to continuous suction Continuous decompression allows • Stomach to regain its normal muscle tone • Ulcer to begin to heal • Inflammation and edema to subside – After several days, NG clamped and residual volumes checked • Common to clamp tube overnight for 8 to 12 hours and measure residual in morning – When aspirate below 200 mL • Within normal range • Oral intake of clear liquids can begin – Watch patient carefully for signs of distress or vomiting. – As residual ↓, solid foods added and tube removed Nursing Implementation • Hemorrhage – Changes in vital signs, ↑ in amount and redness of aspirate • Signal massive upper GI bleeding – ↑ amount of blood in gastric contents – ↓ pain because blood neutralizes acidic gastric contents – Maintain patency of NG tube. • Prevent blood clot blockage. • If blocked, distention results. Nursing Implementation • Perforation – Sudden, severe abdominal pain unrelated in intensity and location to pain that brought patient to hospital • Possibility of perforation – – – – – – Indicated by a rigid, board-like abdomen Severe generalized abdominal and shoulder pain Shallow, grunting respirations Bowel sounds diminished or absent Vital signs every 15 to 30 minutes Stop all oral, NG feeds/drugs until health care provider notified. IV fluids may be increased to replace volume lost. – Ensure any known allergies are reported on chart. • Antibiotic therapy is usually started. Surgical or laparoscopic closure may be necessary if perforation does not heal spontaneously. Nursing Implementation • Gastric outlet obstruction – Can occur at any time • Likely in patients whose ulcer is located close to pylorus – Gradual onset – Constant NG aspiration of stomach contents may relieve symptoms. – If occurs during treatment of acute exacerbation • Regular irrigation of NG tube • Repositioning from side to side – IV fluids for hydration – Accurate I/O – Surgery may be performed if conservative treatment not successful Ambulatory and Home Care • Patient teaching – Disease • Teach basic etiology/pathophysiology. – Drugs – Actions, side effects, danger of taking any medication without health care provider approval – Lifestyle changes • Appropriate changes in diet – Regular follow-up care • Discuss medications. • Encourage compliance with plan of care. • Importance of immediate reporting of N/V, epigastric pain, bloody emesis, or tarry stools Surgical Therapy • Uncommon because of anti secretory agents • Indications for surgical interventions – Unresponsive to medical management – Concern about gastric cancer Billroth I: Gastroduodenostomy Partial gastrectomy with removal of distal 2/3 stomach and anastomosis of gastric stump to duodenum Billroth II: Gastrojejunostomy Partial gastrectomy with removal of distal 2/3 stomach and anastomosis of gastric stump to jejunum Surgical Therapy A, Billroth I procedure (subtotal gastric resection with gastroduodenostomy anastomosis).

Surgical Therapy • Surgical therapies (cont’d) – Vagotomy • Severing of vagus nerve • Can be total or selective – Pyloroplasty • • • • Surgical enlargement of pyloric sphincter Commonly done after vagotomy ↓ gastric motility and gastric emptying If accompanying vagotomy, ↑ gastric emptying Postoperative Complications • Most common – Dumping syndrome – Postprandial hypoglycemia – Bile reflux gastritis Postoperative Complications • Dumping syndrome – 20% of patients experience after surgery. – Direct result of surgical removal of a large portion of stomach and pyloric sphincter – ↓ ability of stomach to control amount of gastric chyme entering small intestine • Large bolus of hypertonic fluid enters intestine • ↑ fluid drawn into bowel lumen – Occurs at end of meal or 15 to 30 minutes after eating – Symptoms include • Weakness, sweating, palpitations, dizziness, abdominal cramps, borborygmi, urge to defecate • Last no longer than an hour Postoperative Complications • Postprandial hypoglycemia – Result of uncontrolled gastric emptying of a bolus of fluid high in carbohydrate into small intestine • ↑ blood sugar • Release of excessive amounts of insulin into circulation – Secondary hypoglycemia occurs with symptoms ~2 hours after meals. – Symptoms include sweating, weakness, mental confusion, palpitations, tachycardia, and anxiety. Postoperative Complications • Bile reflux gastritis – Surgery can result in reflux alkaline gastritis. • Prolonged contact of bile causes damage to gastric mucosa. • May result in back diffusion of H+ ions through gastric mucosa • Peptic ulcer disease may reoccur. – Continuous epigastric distress that ↑ after meals – Administration of cholestyramine (Questran) relieves irritation. Nutritional Therapy Postoperatively • Start as soon as immediate postoperative period has successfully passed. • Patient should be advised to reduce drinking fluid (4 oz) with meals. • Diet should consist of – – – – – Small, dry feedings daily Low carbohydrates Restricted sugar with meals Moderate amounts of protein and fat 30 minutes of rest after each meal. The dietitian usually gives dietary instructions, and the nurse needs to reinforce them. • Location: ulcer on stomach=Gastric Ulcer ulcer on upper intestine=Duodenal Ulcer ulcer on esophagus=Esophageal Ulcer Gastric Ulcer Duodenal Ulcer 30 to 60 min after meal 1.5 to 3 hr after meal Rarely occurs at night Often occurs at night Pain worsens with food ingestion Pain relieved by food ingestion •Peptic ulcer disease can be differentiated between gastric, duodenal, and stress ulcers. •Silent ulcers may occur with pts with diabetes, NSAID users such as aspirin and ibuprofen. •If left untreated, complications may occur such as bleeding, perforation, penetration or the obstruction of the digestion tract. Gastroenteritis • Definition - Gastroenteritis is a condition that causes irritation and inflammation of the stomach and intestines (the gastrointestinal tract). Diarrhea, crampy abdominal pain, nausea, and vomiting are the most common symptoms. • Causes: - Viral infection - Bacterial infection (Salmonella) - Parasites - Food-borne illness (such as shellfish) can be the offending agent. Causes of Gastroenteritis • Viruses and bacteria are very contagious and can spread through contaminated food or water. Gastroenteritis caused by viruses may last one to two days. Bacterial cases can last for a longer period of time. Virus e.g. Norovirus, Rotavirus Bacteria e.g Staphylococci, E. Coli, Shigella, Salmonella, Campylobacter. Clostridium Difficile. Parasite – Giardia (Giardiasis) • Improper handwashing following a bowel movement or handling a diaper can spread the disease from person to person. • Gastroenteritis that is not contagious to others can be caused by chemical toxins, most often found in seafood, food allergies, heavy metals, antibiotics, and other medications. Sign and Symptoms Common symptoms may include: • Low grade fever to 100°F (37.7°C) • Nausea with or without vomiting • Mild-to-moderate diarrhea • Crampy, painful abdominal bloating More serious symptoms: • Blood in vomit or stool • Vomiting more than 48 hours • Fever higher than 101°F (40°C) • Swollen abdomen or abdominal pain • Dehydration - weakness, lightheadedness, decreased urination, dry skin, dry mouth and lack of sweat and tears are characteristic findings. • Signs and symptoms of both include pain, cramping, belching, nausea, and vomiting. Severe cases may include hematemesis. Diarrhea may occur with gastroenteritis. Exams and Diagnostic Tests • Blood and stool tests to determine the cause of the vomiting and diarrhea. • Physical examination. • Complete Blood Count • Ask if other family or friends have similar exposure or symptoms. Ask about the duration, frequency, and description of the patient's bowel movements and whether they are vomiting. • Travel history: Travel may suggest E. coli bacterial infection or a parasite infection from something that client ate or drank. • Exposure to poisons or other irritants: Swimming in contaminated water or drinking from suspicious fresh water such as mountain streams or wells may indicate infection from Giardia - an organism found in water that causes diarrhea. • Diet change, food preparation habits, and storage. Tests for Gastroenteritis • In general, symptoms caused by bacteria or their toxins will become apparent after the following amount of time: Staphylococcus aureus in 2-6 hours Clostridium 8-10 hours Salmonella in 12-72 hours • Medications: If the patient has used broadspectrum or multiple antibiotics recently, they may have antibiotic-associated irritation of the gastrointestinal tract. Other conditions associated with Gastroenteritis • Physical examination will provide reasons for symptoms that may not be related to infection. • If there are specific tender areas in the abdomenappendicitis, gallbladder disease, pancreatitis, diverticulitis, or other conditions that may be the cause of the patient's symptoms. • Other noninfectious gastrointestinal diseases like Crohn's disease or ulcerative colitis must also be considered. Treatments for Gastroenteritis • Antibiotics are not usually prescribed until bacteria have been identified. • Antibiotics may be given for certain bacteria, specifically Campylobacter, Shigella, and Vibrio cholerae, if properly identified through laboratory testing. Otherwise, using any antibiotic or the wrong antibiotic can worsen some infections or make them last longer. • Infections, like salmonella, are not treated with antibiotics. Supportive care of fluids and rest, the body is able to resolve the infection without antibiotics. • For adults, medications to stop vomiting (antiemetics) such as promethazine (Phenergan, Anergan), prochlorperazine (Compazine), or Ondansetron (Zofran). These medications are prescribed as a suppository. • IV fluids • Most common antidiarrheal agents for people older than three years are over-the-counter medications such as diphenoxylate atropine (Lomotil, Lofene, Lonox) or loperamide hydrochloride (Imodium). Nursing Care • Gastritis may be caused by a chemical, thermal, or bacterial insult ( alcohol, aspirin, and chemotherapeutic agents;hot, spicy, rough, or contaminated foods). • Management involves symptomatic treatment measures after removal of the causative agent. • Stop all P.O. intakes until symptoms subside. • Assess the client's symptoms and administer the prescribed symptomatic relief medications such as antacids and antiemetics. • Monitor intake and output. • Administer IV to replace lost fluids. • Weigh daily. • Encourage the prescribed diet.
