  11. 11. Types of Gastric Surgeries <ul><li>Gastroduodenostomy (Billroth I): A subtotal gastrectomy w/ removal of distal stomach; anastomosis to duodenum </li></ul><ul><li>Gastrojejunostomy (Billroth II): A subtotal gastrectomy w/ removal of distal stomach and antrum; anastomosis to jejunum. </li></ul><ul><li>Total gastrectomy: Removal of entire stomach </li></ul><ul><li>Vagotomy: Resection of vagus nerves; may be done to reduce gastric acid secretion in selected segments of the stomach. </li></ul><ul><li>Pyloroplasty: Incision made into the pylorus to enlarge the outlet and relax the muscle; may be done w/ vagotomy to produce less gastric acid and promote gastric emptying. </li></ul>
  12. 12. Postoperative Complications: Nursing Considerations <ul><li>Keep client NPO as ordered </li></ul><ul><li>Use of NG suctioning for 2-3 days as ordered: keeps the operative area clean & eliminates pressure from accumulated fluids </li></ul><ul><li>Keep NGT patent at all times. Irrigate the NGT as ordered (usually w/ approximately 20mL NS): irrigating the NGT incorrectly could disrupt the suture line </li></ul><ul><li>Assess NG drainage carefully. It may be tingged w/ bright-red blood at first. Report if the amount of red blood increases or remains bright red: it is a sign of hemorrhage. The NG fluid should progress towards a normal greenish-yellow color. </li></ul><ul><li>Keep the client in semi-fowler’s position to facilitate drainage. </li></ul><ul><li>Monitor chest tube drainage and chest tube suction: the chest may be opened during the surgery, necessitating the use of test tube & suction postoperatively. </li></ul><ul><li>Provide routine postoperative care, including attention to mouth care and to early ambulation. </li></ul>
  13. 13. Nursing Consideration <ul><li>Include deep breathing & incentive spirometer exercises. Encourage the client to cough gently. Support the incision with a small pillow. </li></ul><ul><li>Monitor & control post-surgical pain. Give pain medications as prescribed. The client may be reluctant to breathe deeply or cough because of incisional pain. Medications facilitate exercise, w/c decreases to postoperative complications. </li></ul><ul><li>Assess dressings for excess drainage. Reinforce dressings as needed. Usually the surgeon observes the incision & does the first dressing change. Excess drainage indicates infection or a rupture of the suture line. </li></ul><ul><li>Give clear liquids when bowel sounds are present. The diet progresses as tolerated. </li></ul>

  16. 16. Abdominal Paracentesis <ul><li>“ abdominal tap” is a procedure that may be necessary for diagnostic purposes or to relieve ascites. </li></ul><ul><li>It is considered diagnostic when fluid is withdrawn for microscopic study or culturing when bleeding or infection is suspected. </li></ul><ul><li>Therapeutic abdominal tap is done when the client is distended with ascitic fluid. </li></ul><ul><li>The abdominal cavity is punctured to obtain a specimen for analysis or to drain excess fluid. </li></ul><ul><li>Because the client also may have difficulty breathing, removal of this fluid will frequently relieve the condition. </li></ul><ul><li>US may be utilized to guide the aspiration of fluid from the abdomen with a large syringe and needle. </li></ul><ul><li>Sometimes a catheter is inserted into the abdominal cavity for continuous drainage. </li></ul>

  21. 21. Candidiasis <ul><li>Known as thrush or moniliasis , is a fungal infection caused by the organism Candida albicans , w/c is part of the normal flora of the oral cavity. </li></ul><ul><li>It is common in newborns, immunosuppressed clients, & clients w/ chronic debilitating diseases such as HIV/AIDS, DM, or alcoholism </li></ul><ul><li>ATB therapies also can lead to candidiasis </li></ul><ul><li>The infection appears as small, white patches on the mucous membranes of the mouth or tongue & may extend into the entire GI tract. </li></ul><ul><li>Oral pharyngeal cultures are recommended when this infection is suspected </li></ul><ul><li>Prophylactic treatment of high-risk clients is indicated </li></ul><ul><li>Treatment consists of nystatin (Mycostatin), saline, & hydrogen peroxide mouth rinses, or vaginal suppositories </li></ul>
  22. 22. <ul><li>Candidiasis </li></ul><ul><li>Known as thrush or moniliasis, is a fungal infection caused by the organism Candida albicans, w/c is part of the normal flora of the oral cavity. </li></ul><ul><li>Herpes Simplex Infection </li></ul><ul><li>Cold sores or fever blisters are painful vesicles that occur on the face, lips, perioral (around the mouth) area, cheeks, & nose. </li></ul><ul><li>Usually caused by herpes simplex virus type 1 (HSV-1) & can be precipitated by stress. </li></ul>
  23. 23. Cancer of the Mouth <ul><li>Many cancers of the mouth are asymptomatic until they have spread. </li></ul><ul><li>Mouth cancer can be treated successfully if discovered early. </li></ul><ul><li>Those who ingest large amounts of ETOH, or engage in risky behaviors such as smoking or using forms of smokeless tobacco (leaf, plug, or snuff), have an increased risk for developing oral cancer. </li></ul><ul><li>Many people tend to ignore sores or irritations in the mouth because they think such symptoms are insignificant. </li></ul>

  25. 25. Treatment… <ul><li>Surgery </li></ul><ul><li>Radium implants </li></ul><ul><li>Deep x-ray therapy </li></ul><ul><li>Combination therapies w/ chemotherapy are also common </li></ul><ul><li>If possible, the malignancy is removed with as wide an excision as necessary to remove all affected structures & lymph nodes </li></ul><ul><li>NG or gastrostomy feedings might be indicated </li></ul><ul><li>The operation is often followed by reconstructive surgery to correct facial defects. </li></ul>
  26. 26. Nursing Considerations… <ul><li>Caring for the client pre & post operatively </li></ul><ul><li>Before surgery, design communication techniques, because the client may be unable to speak as he or she did before surgery </li></ul><ul><li>Postoperatively, observe for hemorrhage & airway obstruction caused by facial edema or aspiration. </li></ul><ul><li>Suction secretions & elevate the head of the bed to make breathing easier. </li></ul><ul><li>As you support the client’s head by placing your hands on either side, instruct the client to breathe deeply & to use the incentive spirometer </li></ul><ul><li>Do not encourage coughing unless congestion is present </li></ul><ul><li>These measures are needed to prevent hypostatic pneumonia </li></ul><ul><li>An emergency airway should be available at the client’s bedside. </li></ul><ul><li>Give mouth care carefully to improve the client’s comfort & prevent odor. </li></ul><ul><li>Take great care to prevent disruption of the suture line </li></ul><ul><li>Give liquids through an NG tube until the client is able to swallow </li></ul><ul><li>Self-care is the goal. </li></ul>

  28. 28. Esophageal Varices
  29. 29. Hiatal Hernia The presence of  a hiatal hernia does not cause any symptoms. Hiatal hernia may increase acid reflux and may worsen GERD and cause esophageal ulcers. Lifestyle changes and dietary changes are very effective in the management of hiatal hernia. Avoiding caffeine, stopping smoking and avoiding alcohol use are all very important. Eating small meals, not wearing tight clothing are also effective. Going to bed with an empty stomach( not eating or drinking for at least 3 hours before bed time ) is also advocated SURGERY is very rarely recommended. Maria Nelson

  31. 31. GERD: Gastro Esophageal Reflux Disease <ul><li>Gastroesophageal reflux disease, or GERD, occurs when the lower esophageal sphincter (LES) does not close properly, and stomach contents splash back, or reflux, into the esophagus. The LES is a ring of muscle located at the far end of the esophagus as it leads into the stomach. It's normal function is to act as a physical barrier between the esophagus and the stomach, protecting the esophagus from harmful gastric acid, and preventing food from being regurgitated. It does this by involuntary tonic contraction. When one eats, food is propelled into the esophagus toward the stomach. It is during swallowing that the LES relaxes and allows passage of food and liquids into the stomach. </li></ul><ul><li>When refluxed stomach acid touches the lining of the esophagus, it causes a burning sensation in the chest or throat called heartburn. The fluid may even be tasted in the back of the mouth, and this is called acid indigestion. Occasional heartburn is common but does not necessarily mean one has GERD. Heartburn that occurs more than twice a week may be considered GERD, which can eventually lead to more serious health problems. </li></ul>Sophia Alvarado
  32. 32. <ul><li>Typical symptoms include a burning sensation in the chest, and regurgitation of food. These symptoms are general, and not necessarily specific for reflux disease. For instance, patients may experience chest pain or burning as a result of a primary cardiac problem, or they may be a manifestation of another primary esophageal disorder. It is imperative that the cause of the symptoms be clearly delineated by your physician so the proper therapy may be instituted. Regurgitation is also a relatively common complaint. </li></ul><ul><li>Atypical symptoms of GERD include: </li></ul><ul><ul><li>asthma; chronic sinusitis; </li></ul></ul><ul><ul><li>chronic hoarseness; difficulty swallowing (dysphagia); </li></ul></ul><ul><ul><li>vomiting; choking sensation at night time; </li></ul></ul><ul><ul><li>pneumonias; excessive salivation </li></ul></ul>Sophia Alvarado

MEDICATIONS <ul><li>CAN DECREASE LES PRESSURE </li></ul><ul><ul><li>oral contraceptives nitrates theophllyine narcotics calcium channel blockers ß-adrenergic agonists a-adrenergic agonists diazepam dopamine nicotine patch </li></ul></ul><ul><li>CAN DIRECTLY INJURE ESOPHAGEAL LINING </li></ul><ul><ul><li>aspirin NSAIDS (i.e.: ibuprofen) quinidine tetracycline potassium iron </li></ul></ul>Sophia Alvarado
  35. 35. GERD: TREATMENT <ul><li>Treatment for GERD may involve one or more of the following lifestyle changes, medications, or surgery. </li></ul><ul><li>The goals of therapy for GERD include - - - </li></ul><ul><ul><li>Symptomatic relief </li></ul></ul><ul><ul><li>Resolution of esophagitis (inflammatory changes of the esophagus as a result of abnormal acid exposure) </li></ul></ul><ul><ul><li>Prevention of complications. </li></ul></ul>Sophia Alvarado
  36. 36. Barrett’s Esophagus… <ul><li>Barrett's esophagus is a premalignant condition in which the normal stratified squamous epithelium of the esophagus is replaced by a metaplastic columnar epithelium as a complication of chronic gastroesophageal reflux disease (GERD). The metaplastic epithelium of Barrett's esophagus is variously called &quot;Barrett's metaplasia&quot;, &quot;specialized columnar metaplasia&quot; or &quot;intestinal metaplasia&quot;. This metaplasia predisposes to the development of esophageal adenocarcinoma and adenocarcinoma of the gastric cardia. </li></ul><ul><li>Endoscopy with biopsy is therefore recommended in patients who have long-standing or frequent GERD symptoms to determine whether or not Barrett's esophagus has developed. If Barrett's esophagus is detected, the patient should be enrolled in a program of endoscopic surveillance for the detection of cancer when it is early and curable. Only about 5-10% of patients with Barrett's esophagus will progress to cancer, but esophagectomy is recommended for those who do. Surgery is the standard of care for patients who develop an early adenocarcinoma in Barrett's esophagus because it has a high cure rate and removes the residual premalignant metaplasia. </li></ul>Sophia Alvarado

  85. 85. IBS: Treatment… <ul><li>Explore lifestyle patterns & emotional stressors </li></ul><ul><li>Counseling may be needed, along w/ biofeedback & relaxation training, w/c has proven helpful for people w/ IBS; High-fiber diet & agents that add bulk = help to promote an even and consistent stool to pass through the bowel; adequate oral fluids & regular meal patterns </li></ul><ul><li>Medications: sedatives or tranquilizers; Xanax (alprazolam) = help to quiet the bowel’s activity & provide relaxation; dicyclomine Hcl (Bentyl) + hyoscyamine (Donnatal) = antispasmodic that can relieve pain & cramping </li></ul><ul><li>Common S/E: dry mouth, blurred vision, & dizziness; some clients require occasional antidiarrheal agents (loperamide-Immodium) </li></ul>
  86. 86.

  87. 87. CONSTIPATION <ul><li>A condition in which the client has infrequent, hard bowel movements accompanied by mucus. </li></ul><ul><li>May be acute or chronic; the client may have a fecal impaction with loose, watery stool & mucus traveling around the constipated stool. </li></ul><ul><li>Dehydration, cancer, chemical dependency, or mechanical obstruction may cause this condition; it also may be a psychomatic disorder. </li></ul>Ben Mayunga
  88. 88. Constipation… <ul><li>Warn client not to strain while having a stool </li></ul><ul><li>Encourage to avoid worrying about constipation because undue concern can compound the problem </li></ul><ul><li>Teach client to drink a great deal of fluids, drink prune juice or eat bran, ↑ dietary bulk, exercise, & follow a regular schedule for defecation. </li></ul><ul><li>Explain the importance of evacuating the bowel whenever the client feels the urge; postponing the act desensitizes the bowel to the presence of feces. </li></ul><ul><li>Enemas for diagnostic tests/procedure; alleviate symptoms of constipation or distention, or to administer specific medications & fluids </li></ul><ul><li>Digital removal of fecal impaction may be necessary for severely constipated or paralyzed clients – only done after stool softeners & enemas failed </li></ul><ul><li>CAUTION: </li></ul><ul><ul><li>Loose, watery stools may not be diarrhea; they may signify severe constipation with leakage of water around the blockage; assess the client for fecal impaction </li></ul></ul>Ben Mayunga

  91. 91.
  92. 92. Diagnosis… <ul><li>If chronic and not self-limiting, diarrhea symptoms must be evaluated for possible causes (particularly before the client self-medicates). </li></ul><ul><li>Diarrhea that continually awakens a client from normal sleep often indicates intestinal pathology. A bacterial infection and IBS should be ruled out. </li></ul><ul><li>Stool tests, including cultures, occult blood tests, & O&P smears, are performed. </li></ul><ul><li>Hematology studies indicate infection or inflammatory processes. </li></ul><ul><li>Lower GI barium exams are done to rule out pathologic causes </li></ul>Ben Mayunga
  93. 93. Therapeutic Interventions… <ul><li>Give antidiarrheal drugs as ordered.Most antidiarrheal drugs suppress GI motility, thus allowing for more fluid absorption. </li></ul><ul><li>Withhold food for 24 hours during the first 24-hour period of diarrhea. It allows & promote bowel rest & relaxation & avoidance of irritation. </li></ul><ul><li>Provide the following alterations as allowed - - - </li></ul><ul><ul><li>Bulk fiber (ie, cereal, grains, Metamucil) </li></ul></ul><ul><ul><li>“ Natural” antidiarrheals (ie, pretzel, matzos, cheese) </li></ul></ul><ul><ul><li>Avoidance of stimulants (ie, caffeine, carbonated beverages) Stimulants may ↑ GI motility & worsen diarrhea </li></ul></ul><ul><li>Check for fecal impaction by digital examination. Liquid stool (apparent diarrhea) may seep past a fecal impaction. </li></ul>Ben Mayunga
  94. 94. <ul><li>Encourage fluids; consider nutritional support. Fluids compensate for malabsorption & loss of nutrients. </li></ul><ul><li>Evaluate appropriateness of physician’s radiograph protocols for bowel preparation on basis of age, weight, condition, disease, and other therapies. Elderly, frail, or those patients already depleted may require less bowel preparation or additional intravenous (IV) fluid therapy during preparation. </li></ul><ul><li>Assist with or administer perianal care after each bowel movement (BM). This prevents perianal skin excoriation. </li></ul><ul><li>For patients with enteral tube feeding, employ the following: </li></ul><ul><ul><li>Change feeding tube equipment according to institutional policy, but no less than every 24 hours. Contaminated equipment can cause diarrhea. </li></ul></ul><ul><ul><li>Administer tube feeding at room temperature. Extremes of temperature can stimulate peristalsis. </li></ul></ul><ul><ul><li>Initiate tube feeding slowly. </li></ul></ul><ul><ul><li>Decrease rate or dilute feeding if diarrhea persists or worsens. This prevents hyperosmolar diarrhea. </li></ul></ul>Ben Mayunga
  95. 95. Medications for Treating Diarrhea <ul><li>Motility reduction: loperamide (Imodium), diphenoxylate (Lomotil) </li></ul><ul><li>Bile salt-binding agent: cholestyramine (Questran) </li></ul><ul><li>Antibiotics: to treat bacterial/microbial diarrhea </li></ul><ul><li>Nursing Considerations </li></ul><ul><ul><li>Meds C/I in poisoning until the poison is removed from the digestive tract. </li></ul></ul><ul><ul><li>Loperamide & diphenoxylate have the potential for drug dependence, they may cause sedation, dizziness, constipation, & drying of mucous membranes </li></ul></ul><ul><ul><li>Diphenoxylate is not recommended for use in pregnancy </li></ul></ul><ul><ul><li>Cholestyramine may cause constipation, nausea, bloating, abdominal pain, and rash. To administer, sprinkle powder on surface of liquid or wet food; carbonated beverages may foam excessively. Do not administer with other medications because it blocks their absorption </li></ul></ul>Ben Mayunga
  96. 96. Inflammatory Bowel Disease (IBD) <ul><li>a general term for ulcerative colitis & Crohn’s disease. </li></ul><ul><li>research suggests that environmental, immunologic, hereditary, age, & cultural factors influence this disease. </li></ul><ul><li>the causes & cure, however, are unknown </li></ul><ul><li>Ulcerative colitis involves inflammation & ulceration of mucosa & submucosa (colon’s lining). It can span the entire length of the colon, but most frequently begins in the rectum & distal colon. </li></ul><ul><li>a chronic ulcerative colitis (CUC) implies long-standing disease.

Signs & symptoms… <ul><li>Acute attack - begins with progressively severe generalized abdominal pain, which later localizes as pain & tenderness in the right lower quadrant midway between the umbilicus & the crest of the ilium (McBurney’s point). An attack may subside and recur. </li></ul><ul><li>Ultrasound can often diagnose an enlarged appendix </li></ul><ul><li>Rebound tenderness usually present; the quality of tenderness relates to the exact location of the appendix; or relief of pain when palpation pressure applied to RLQ followed by pain on pressure release. </li></ul><ul><li>Nausea, vomiting, a mild to moderate fever, and an increase in leukocytes accompany the pain. </li></ul><ul><li>A ruptured appendix will result in more severe symptoms associated with peritonitis </li></ul>Imelda de los Sanstos
  107. 107. PERITONITIS <ul><li>An inflammation of the peritoneum, the membrane that lines the abdominal cavity and covers the abdominal organs </li></ul><ul><li>It usually results from perforation of the intestine or appendix, through which intestinal contents escape into the abdomen. </li></ul><ul><li>Intestinal tract + bacteria = perforation, inflammation, & peritoneal infection </li></ul><ul><li>Most common causes - - - </li></ul><ul><ul><li>Appendicitis; ulcer, IBD; abscessed diverticula; cancer </li></ul></ul><ul><ul><li>Infected uterine tube </li></ul></ul><ul><ul><li>Ruptured tubal pregnancy </li></ul></ul><ul><ul><li>Ruptured uterus </li></ul></ul><ul><li>May be generalized, extending throughout the peritoneum, or it may be localized as an abscess </li></ul>Steven Dorn

  111. 111. Cancer of the Small Intestine <ul><li>CA occurs rarely in the small intestine. However, an ↑’d risk of CA accompanies ulcerative colitis; if it does occur in the small intestine, the person’s prognosis is usually poor because the disease is difficult to discover in its early stage; usually it’s asymptomatic </li></ul><ul><li>As the cancer advances, pain may be present; diarrhea, anorexia, nausea, & vomiting; perforation or obstruction may occur </li></ul><ul><li>Portion of the bowel containing the tumor may be removed & the ends of the bowel joined; such anastomosis is impossible if malignancy is extensive </li></ul><ul><li>Suction relieves distention; IV fluids; ATB’s </li></ul><ul><li>postoperative nursing care is routine </li></ul>Jessica Barrientos

  114. 114. Hemorrhoids <ul><li>Swollen (varicose) veins of the anus or rectum; external hemorrhoids protrude as lumps around the anus; painful, esp. if the client is constipated & strains to have a BM; they may alternately appear & disappear </li></ul><ul><li>S/sx: usually external hemorrhoids do not bleed, but they may become large, painful, & itchy; uterine pressure on the rectum during pregnancy, intra-abdominal tumors, constipation, diarrhea, obesity, CHF, & portal HTN are major causes; internal hemorrhoids may bleed, unlikely to be painful – always protrude on defecation & clients can push it back w/ a finger; Proctoscope allows the provider to inspect inside the rectum, to visualize hemorrhoids, & take a biopsy sample </li></ul>Milton Marino
  115. 115. Milton Marino
  116. 116. Treatment . . . <ul><li>Sometimes disappear w/o treatment </li></ul><ul><li>Warm sitz baths, anesthetic, ointments, or witch hazel compresses (Tucks) </li></ul><ul><li>Keeping stools soft through proper diet & stool softeners; correcting constipation can prevent & eliminate hemorrhoids </li></ul><ul><li>If surgery is necessary, the veins are tied off & excised or cauterized; Sometimes a solution is injected to shrink (sclerose) the tissues </li></ul><ul><li>Occasionally, hemorrhoidectomy must be done if the hemorrhoid is thrombosed, causing vascular obstruction </li></ul><ul><li>This situation is not life-threatening; surgery is done to relieve pain </li></ul>Milton Marino
  117. 117. Nursing Considerations … <ul><li>Cleansing enema night before surgery – given “until returns run clear” the morning of the operation </li></ul><ul><li>Cleanse rectal area & shave it </li></ul><ul><li>Position patient on the side or abdomen post-surgery to relieve pressure on the operative area </li></ul><ul><li>Give analgesics as ordered </li></ul><ul><li>Liquid diet permitted for the 1 st meal post surgery; thereafter, a full-diet is allowed </li></ul><ul><li>Emphasize early ambulation </li></ul><ul><li>Allow client to sit-up – rubber ring or flotation pad under buttocks helps relieve pressure on the operative area </li></ul>Milton Marino
  118. 118. ANAL FISSURE <ul><li>An ulcer in the skin of the anal wall </li></ul><ul><li>Causes severe pain on defecation & sometimes slight bleeding </li></ul><ul><li>Client may dread the pain so much that he or she delays defecation & becomes constipated </li></ul><ul><li>Sitz baths & local anesthetic ointments are commonly used to treat this problem </li></ul><ul><li>Stool softeners are given </li></ul><ul><li>The only cure for this condition is surgical removal of the ulcer </li></ul>
  119. 119. Anal Abscess & Anal Fistula <ul><li>Anal abscess is caused by infected tissue around the rectal area; painful & may be accompanied by fever & chills; abscess is usually incised & drained, or it may rupture spontaneously </li></ul><ul><li>Anal fistula usually develops as a result of an anal abscess; small tunnel forms in the tissues that discharges pus & feces through one or more opening onto the skin </li></ul>
  120. 120. Treatment … <ul><li>Surgery is necessary to open fistulous tract; </li></ul><ul><li>Medication-impregnated packing is inserted to keep the wound’s edges apart = allow the tissues to heal by granulation, thus eliminating the fistula; </li></ul><ul><li>The fistula must heal inside out, or another abscess will form </li></ul>
  121. 121. Nursing Considerations … <ul><li>Generally, nursing care is similar to that for any client after rectal surgery, w/ the following differences - - - </li></ul><ul><ul><li>Pack the fistula wound w/ petroleum gauze & change the dressing every day </li></ul></ul><ul><ul><li>Drainage from the abscess is profuse, purulent, & foul smelling – need to change the dressing on the wound frequently </li></ul></ul><ul><ul><li>Dispose of dressings properly & wear gloves to prevent the spread of disease </li></ul></ul><ul><ul><li>Keep fistula draining – if it stops draining before the entire area is filled in with granulation tissue, another abscess will form </li></ul></ul>
  122. 122. Cancer of the Rectum <ul><li>Exact cause is unknown </li></ul><ul><li>Risk factors: family hx of colon or rectal cancer, hx of rectal polyps, hx of IBD, & a diet high in fat & protein & low in fiber </li></ul><ul><li>Symptoms: rectal pain, alternating constipation & diarrhea, feeling of incomplete evacuation after a BM,bloody stool, & tenesmus </li></ul><ul><li>Rectal is not common as colon cancer </li></ul><ul><li>Diagnosis is made by sigmoidoscopy with biopsy of polyps </li></ul>
  123. 123. Treatment … <ul><li>Growth upper part of rectum = can be removed w/o removal of the rectal sphincter; ultimately the bowel will function normally </li></ul><ul><li>If tumor involves rectal opening, a dual operation is necessary through the abdomen from above (including a colostomy) & through the perineum below = surgery called abdominal-perineal resection </li></ul><ul><li>W/ staplers & other newest instruments, some surgeons have successfully retained the rectal sphincter, performing a low resection & anastomosis to eliminate the need for a permanent colostomy </li></ul>
  124. 124. Nursing Considerations… <ul><li>Carefully assess vital signs </li></ul><ul><li>Check dressings for bleeding at regular intervals </li></ul><ul><li>The danger of shock after the surgery is great </li></ul><ul><li>Colostomy care; administering parenteral fluids (including blood transfusion); NG suctioning, caring for bladder drainage (a FC is usually inserted in the bladder), & irrigating & caring for drainage from the perineal wound </li></ul><ul><li>Turn client frequently to prevent respiratory complications & thrombophlebitis; finding a comfortable position may be difficult </li></ul><ul><li>Encourage to ambulate usually w/in 2 days </li></ul>

  127. 127. Liver Failure <ul><li>Hepatic coma is a failure of the liver cells to clear toxins – waste products build up in the body = diminished cerebral function </li></ul><ul><li>can be an acute or chronic condition </li></ul><ul><li>causes: extensive damage to liver cells, such as may occur after massive GI hemorrhage, as a complication of some surgical procedures, after massive infections, & following an overdose of certain drugs </li></ul><ul><li>also occurs in the client with alcoholic liver disease such as cirrhosis </li></ul>Martin Villamor
  128. 128. Signs & Symptoms: Liver Failure <ul><li>Tremors & mental changes (seizures, stupor, & coma) </li></ul><ul><li>Fulminant hepatic failure involves progressive multi system failure -massive liver cell death </li></ul><ul><li>Acute hepatitis B infections may be the initial causative agent </li></ul><ul><li>confused, somnolent, or comatose & usually have ascites, edema, coagulopathy, & a shrinking liver </li></ul><ul><li>Mortality rate - high, & care is supportive </li></ul><ul><li>Diagnosis is made by liver function tests; blood ammonia levels are ↑ because liver cell cannot convert ammonia to urea; ammonia, a by-product of protein metabolism, is toxic to the brain </li></ul>Martin Villamor
  129. 129. TREATMENT: Liver Failure <ul><li>Symptomatic, including control of bleeding, a low-protein diet, & careful management of f/e balance </li></ul><ul><li>Antibiotics may be given, and in some cases, corticosteroids </li></ul><ul><li>Client’s prognosis is guarded, & the possibility of successful treatment decreases w/ each episode </li></ul><ul><li>In Practice: Nursing Care Guidelines 87-4 pg 1453 for nursing care of the client with a liver failure </li></ul>Martin Villamor
  130. 130. CIRRHOSIS <ul><li>Cirrhosis is a disease in which the cells throughout the liver are progressively destroyed. The liver tissue is replaced by areas with normal new cells as well as scar tissue, which alters the structure of the organ. The flow of blood and lymph through the damaged liver is much less efficient, and eventually the liver fails. </li></ul>Chairat Sampanpaisal
  131. 131. Cirrhosis: Causes … <ul><li>Cirrhosis represents an attempt by the liver to rebuild itself and continue despite injury. The injury may be a sudden and massive infection, as in acute hepatitis, or it may occur in a less dramatic manner over a period of months or years, as in chronic active hepatitis or obstruction of the bile ducts within the liver. </li></ul><ul><li>The process of obstruction starts with inflammation and progresses to scarring and then closure of the ducts. A similar condition is caused by obstruction of the external bile ducts by a stone, scar, inborn defect, or tumor. The damage can also be caused, slowly and steadily, by alcohol abuse, which is by far the most common cause of cirrhosis. Other causes include the following: </li></ul><ul><ul><li>Use of certain medications </li></ul></ul><ul><ul><li>Inborn errors in physical or chemical processes of the body </li></ul></ul><ul><ul><li>Syphilis </li></ul></ul><ul><ul><li>Passive liver congestion, due to inability of the heart to accept a normal flow of blood from the liver or to obstruction of one of the drainage systems of the liver </li></ul></ul><ul><ul><li>Long-term infection with hepatitis B or C virus </li></ul></ul>Chairat Sampanpaisal
  132. 132. Cirrhosis: Symptoms … <ul><li>Frequently, because it imitates many other diseases, cirrhosis is not suspected until it is well advanced. </li></ul><ul><li>Many symptoms of cirrhosis are the result of high blood pressure in the portal vein, which brings blood from the intestinal area to the liver. In cirrhosis, the liver cannot handle a normal flow of blood, so the pressure in the portal vein rises. </li></ul><ul><li>One result is that fluid from the blood is lost into the abdominal cavity, a condition called ascites. The fluid may accumulate and press against the diaphragm (the muscular wall separating the abdominal and chest cavities) and interfere with breathing. Collateral blood vessels form to carry away the excess blood into the general circulation. There may be bleeding in the esophagus or stomach when these smaller collateral vessels burst under pressure. The patient may vomit blood. Serious, life-threatening hemorrhage may occur. </li></ul>Chairat Sampanpaisal
  133. 133. Symptoms: <ul><li>Symptoms include general weakness, a vague feeling of being unwell, loss of appetite, loss of weight, and a loss of interest in sex. </li></ul><ul><li>There may be a dull abdominal ache, nausea, constipation, or diarrhea. In a malnourished patient, the tongue may be inflamed. </li></ul><ul><li>The liver may be enlarged and firm or, in advanced cases, shrunken. </li></ul><ul><li>Other symptoms include an enlarged spleen, mottled redness of the mound at the base of the thumb, &quot;spider veins&quot; on the skin of the upper body, loss of hair from the chest and the pubic area, diminished size of the testes, and tingling sensations in the skin of the hands and feet. </li></ul>Chairat Sampanpaisal
  134. 134. Cirrhosis: Diagnosis … <ul><li>A liver biopsy is used to diagnose cirrhosis of the liver. A hollow needle is inserted through the skin and into the liver itself to obtain a tissue sample for analysis. Examination of tissue from a diseased liver reveals destruction of cells and scarring. </li></ul><ul><li>Other diagnostic procedures include nuclear medicine scanning, in which radioactive material is administered and its distribution to the liver is recorded on X-ray film. X-ray pictures are taken of the gallbladder and of bile ducts both inside the liver and leading from it. Important clues that may be found in blood and urine tests include the presence of high levels of bile pigments in the blood, a low red blood cell count (anemia), vitamin and mineral deficiencies, and low levels of protein in the blood </li></ul>Chairat Sampanpaisal
  135. 135. Chairat Sampanpaisal
  136. 136. Cirrhosis: Treatment … <ul><li>Treatment is aimed first at removing the cause of the original injury. For example, an alcoholic patient is told to stop drinking and is placed on a well-balanced diet. Often, thiamin (vitamin B1) and folate supplements are also given. </li></ul><ul><li>If a stone is obstructing an external bile duct, it can be removed. Fluids and salt are usually restricted, to prevent fluid buildup. </li></ul><ul><li>Liver transplantation is sometimes considered. </li></ul><ul><li>Good care includes getting plenty of rest and avoiding infection, which places stress on the liver. </li></ul><ul><li>Avoidance of alcohol intake is paramount in the treatment of cirrhosis and most other liver diseases. A physician should be consulted before any medication, including over-the-counter preparations, is taken. </li></ul>Chairat Sampanpaisal
  137. 137. Treatment … <ul><li>In the client with liver failure, at least 2 months are needed before improvements can be noted. </li></ul><ul><li>The treatment goal is to stop or delay the progression of symptoms. </li></ul><ul><li>The medication lactulose (Cephulac) will promote ammonia retention & excretion through the GI tract. </li></ul><ul><li>To relieve pressure from the fluid of ascites, abdominal paracentesis may be performed. </li></ul><ul><li>Providing a safe & controlled environment will prolong life & stabilize the condition. </li></ul><ul><li>Care must be taken to prevent complications associated with the client’s activity intolerance, such as pneumonia & thrombophlebitis. </li></ul>Chairat Sampanpaisal
  138. 138. Hepatitis <ul><li>An acute or chronic condition of liver inflammation that also may be accompanied by liver tissue damage. </li></ul><ul><li>Viruses are the most prevalent causes affecting several hundred million people throughout the world. </li></ul><ul><li>Alcohol, some drugs, & some autoimmune conditions also cause forms of hepatitis </li></ul>Pavel

Hepatitis A… <ul><li>Prevention </li></ul><ul><ul><li>Hepatitis A vaccine is the best protection. </li></ul></ul><ul><ul><li>Short-term protection against hepatitis A is available from immune globulin. It can be given before and within 2 weeks after coming in contact with HAV.  </li></ul></ul><ul><ul><li>Always wash your hands with soap and water after using the bathroom, changing a diaper, and before preparing and eating food. </li></ul></ul><ul><li>Vaccine Recommendations </li></ul><ul><ul><li>Vaccine is recommended for the following persons from 12 months of age and older; Travelers to areas with increased rates of hepatitis A </li></ul></ul><ul><ul><li>Men who have sex with men; Injecting and non-injecting drug users </li></ul></ul><ul><ul><li>Persons with clotting-factor disorders (e.g. hemophilia); Persons with chronic liver disease; Children living in areas with increased rates of hepatitis A during the baseline period from 1987-1997. </li></ul></ul><ul><li>Trends & Statistics </li></ul><ul><ul><li>Occurs in epidemics both nationwide and in communities </li></ul></ul><ul><ul><li>During epidemic years, the number of reported cases reached 35,000. </li></ul></ul><ul><ul><li>In the late 1990s, hepatitis A vaccine was more widely used and the number of cases reached historic lows. </li></ul></ul><ul><ul><li>One-third of Americans have evidence of past infection (immunity). </li></ul></ul>Pavel
  143. 143. Hepatitis B <ul><li>Hepatitis B is a serious disease caused by a virus that attacks the liver. The virus, which is called hepatitis B virus (HBV), can cause lifelong infection, cirrhosis (scarring) of the liver, liver cancer, liver failure, and death. </li></ul><ul><li>Hepatitis B vaccine is available for all age groups to prevent hepatitis B virus infection. </li></ul>Pavel
  144. 144. Hepatitis C <ul><li>Hepatitis C is a disease of the liver caused by the hepatitis C virus (HCV). You may be at risk for hepatitis C and should contact your medical care provider for a blood test if you: </li></ul><ul><ul><li>were notified that you received blood from a donor who later tested positive for hepatitis C. </li></ul></ul><ul><ul><li>have ever injected illegal drugs, even if you experimented a few times many years ago </li></ul></ul><ul><ul><li>have evidence of liver disease (e.g., persistently abnormal ALT levels) </li></ul></ul>Pavel
  145. 145. Hepatitis D <ul><li>Hepatitis D is a liver disease caused by the hepatitis D virus (HDV), a defective virus that needs the hepatitis B virus to exist. </li></ul><ul><li>Hepatitis D virus (HDV) is found in the blood of persons infected with the virus. </li></ul>Pavel
  146. 146. Hepatitis E <ul><li>Hepatitis E is a liver disease caused by the hepatitis E virus (HEV) transmitted in much the same way as hepatitis A virus. </li></ul><ul><li>Hepatitis E, however, does not occur often in the United States. </li></ul>Pavel
  147. 147. LIVER ABSCESS <ul><li>caused by the spread of infection from some part of the intestinal tract, perhaps the appendix or gallbladder, or by obstruction of the bile tracts. </li></ul><ul><li>Symptoms are chills, fluctuating temperature, extreme weight loss, n/v, abdominal distention, & right-sided pain in the abdomen & shoulder. Jaundice occurs frequently; pain over the liver is a later symptom. </li></ul><ul><li>If the abscess burst – scatters infection through the abdominal or chest cavity. </li></ul><ul><li>ATBs are given, & the outcome depends on how successful the person is at combating the infection. </li></ul><ul><li>Sometimes an attempt is made to establish drainage by surgery. </li></ul><ul><li>Standard Precautions help prevent the spread of infection </li></ul>
  148. 148. Liver Transplantation <ul><li>Life-threatening end-stage liver diseases have been treated with transplant. </li></ul><ul><li>The success of the transplant relates closely to the body’s acceptance of the foreign organ, technical difficulties, the hazards of immunusuppression, & the availability of a functioning liver for transplant. </li></ul><ul><li>The transplanted liver may be a total replacement or a liver segment. </li></ul><ul><li>During the surgical procedure, hemorrhage is likely and many units of blood are needed. </li></ul>

  169. 169. Anorexia Nervosa: Overview, Causes, & Risk Factors <ul><li>The exact cause of this disorder is not known, but social attitudes towards body appearance and family factors are believed to play a role in its development. The condition usually occurs in adolescence or young adulthood. It is more common in women, affecting 1-2% of the female population and only 0.1-0.2% of males. </li></ul><ul><li>Anorexia is seen mainly in Caucasian women who are high academic achievers and have a goal-oriented family or personality. Some experts have suggested that conflicts within a family may contribute to anorexia. It is thought that anorexia is a way for a child to draw attention away from marital problems, for example, and bring the family back together. </li></ul><ul><li>Other psychologists have suggested that anorexia may be an attempt by young women to gain control and separate from their mothers. The causes, however, are still not well understood. </li></ul>Aram Z
  170. 170. Anorexia Nervosa: S/S <ul><li>weight loss of 15% or greater below the expected weight </li></ul><ul><li>inappropriate use of laxatives, enemas, or diuretics (water pills) in an effort to lose weight </li></ul><ul><li>self-imposed food intake restrictions, often hidden </li></ul><ul><li>absence of menstruation </li></ul><ul><li>skeletal muscle atrophy </li></ul><ul><li>loss of fatty tissue </li></ul><ul><li>low BP </li></ul><ul><li>dental cavities may be present with self-induced vomiting </li></ul><ul><li>blotchy or yellow skin </li></ul><ul><li>depression may be present in addition to the eating disorder </li></ul><ul><li>most individuals with anorexia nervosa refuse to recognize that they have an eating disorder (denial) </li></ul>
  171. 171. Anorexia Nervosa: Treatment <ul><li>The biggest challenge in treating anorexia nervosa is having the patient recognize that their eating behavior is itself a problem, not a solution to other problems. This means that most individuals enter treatment when their condition is fairly advanced. </li></ul><ul><li>The purpose of treatment is first to restore normal body weight and eating habits, and then attempt to resolve psychological issues. Hospitalization may be indicated in some cases (usually when body weight falls below 30% of expected weight). </li></ul><ul><li>Supportive care by health care providers, structured behavioral therapy, psychotherapy, and anti-depressant drug therapy are some of the methods that are used for treatment. Severe and life-threatening malnutrition may require IV feeding. </li></ul>
  172. 172. Anorexia Nervosa: Complications <ul><li>The presence of any of these suggests a severe disease, and hospitalization may be required: </li></ul><ul><ul><li>severe dehydration, possibly leading to cardiovascular shock </li></ul></ul><ul><ul><li>electrolyte imbalance (such as potassium insufficiency) </li></ul></ul><ul><ul><li>cardiac arrythmias related to the loss of cardiac muscle and electrolyte imbalance </li></ul></ul><ul><ul><li>severe malnutrition </li></ul></ul><ul><ul><li>thyroid gland deficiencies which can lead to cold intolerance and constipation </li></ul></ul><ul><ul><li>appearance of fine baby-like body hair (lanugo) </li></ul></ul><ul><ul><li>bloating or edema </li></ul></ul><ul><ul><li>decrease in white blood cells which leads to increased susceptibility to infection </li></ul></ul><ul><ul><li>osteoporosis </li></ul></ul><ul><ul><li>tooth erosion and decay with self-induced vomiting </li></ul></ul><ul><ul><li>seizures related to fluid shifts due to excessive diarrhea or vomiting </li></ul></ul>Aram Z
  173. 173. BULIMIA <ul><li>Bulimia is an illness defined by food binges, or recurrent episodes of significant overeating, that are accompanied by a sense of loss of control. The affected person then uses various methods -- such as vomiting or laxative abuse -- to prevent weight gain. </li></ul><ul><li>Someone with bulimia may also suffer from anorexia nervosa, an eating disorder involving severe, chronic weight loss that proceeds to starvation, but many bulimics do not suffer from anorexia. </li></ul>Aram Z
  174. 174. Bulimia: Overview, Causes, & Risk Factors <ul><li>In bulimia, eating binges may occur as often as several times daily for many months. These binges cause a sense of self-disgust, which leads to compensatory behaviors like self-induced vomiting or excessive exercise. A person with bulimia may also abuse laxatives, diuretics or enemas in order to prevent weight gain. </li></ul><ul><li>Such behaviors can be quite dangerous and may lead to serious medical complications over time. For example, the stomach acid which is introduced into the esophagus (the tube from the mouth to the stomach) during frequent vomiting can permanently damage this area. </li></ul><ul><li>Women are much more commonly affected than men. The affected person is usually aware that her eating pattern is abnormal and may experience fear or guilt associated with the binge-purge episodes. Although the behavior is usually secretive, clues to this disorder include overactivity, peculiar eating habits or rituals, and frequent weighing. Body weight is usually normal, although the person may perceive themselves as overweight. If bulimia is accompanied by anorexia, body weight may be extremely low. The exact cause of bulimia is unknown, but factors thought to contribute to its development are family problems, perfectionist personalities, and an overemphasis on physical appearance. Bulimia may also be associated with depression and occurs most often in adolescent females. </li></ul>Aram Z
