Altered Bowel Elimination in human being
- 1.
- 2. Introduction • Elimination ofthe waste products of digestion from the body is essential to health. The excreted waste products are referred to as feces or stool. • Defecation is the expulsion of feces from the anus and rectum. • It is also called a bowel movement. • The frequency of defecation is highly individual, varying from several times per day to two or three times per week.
- 3. Factors affecting Defecation •Development
- 4. Factors affecting Defecationcont.….. Diet • Sufficient bulk (cellulose, fiber) in the diet is necessary to provide fecal volume. • Inadequate intake of dietary fiber contributes to the risk of developing obesity, type 2 diabetes, coronary artery disease, and colon cancer. • It is important to drink plenty of water because fiber works best when it absorbs water. • Foods that may influence bowel elimination include the following: • Gas-producing foods, such as cabbage, onions, cauliflower, bananas, and apples • Laxative-producing foods, such as chocolate and alcohol • Constipation-producing foods, such as cheese, pasta, eggs, and lean meat
- 5. Factors affecting Defecationcont.….. Fluid Intake and Output • Even when fluid intake is inadequate or output (e.g., urine or vomitus) is excessive for some reason, the body continues to reabsorb fluid from the chyme as it passes along the colon. • The chyme becomes drier than normal, resulting in hard feces. • Reduced fluid intake slows the chyme’s passage along the intestines, further increasing the reabsorption of fluid from the chyme. • Healthy fecal elimination usually requires a daily fluid intake of 2000 to 3000 mL. • If chyme moves abnormally quickly through the large intestine, however, there is less time for fluid to be absorbed into the blood; as a result, the feces are soft or even watery
- 6. Factors affecting Defecationcont.….. Activity • Activity stimulates peristalsis - facilitating the movement of chyme along the colon. • Weak abdominal and pelvic muscles are often ineffective in increasing the intra abdominal pressure during defecation or in controlling defecation. • Weak muscles can result from lack of exercise, immobility, or impaired neurologic functioning. Ex: Patients confined to bed are often constipated.
- 7. Factors affecting Defecationcont.….. Psychologic Factors • individuals who are anxious or angry experience increased peristaltic activity and subsequent nausea or diarrhea. • individuals who are depressed may experience slowed intestinal motility, resulting in constipation. Defecation Habits • Early bowel training may establish the habit of defecating at a regular time. • Many individuals defecate after breakfast due to the gastrocolic reflex (increased peristalsis of the colon after food has entered the stomach). • If an individual ignores this urge to defecate - water continues to be reabsorbed, making the feces hard and difficult to expel. • When the normal defecation reflexes are inhibited or ignored - reflexes tend to be progressively weakened. • Habitually ignored - the urge to defecate is ultimately lost. • Adults may ignore these reflexes because of the pressures of time or work. • Hospitalized clients may suppress the urge because of embarrassment about using a bedpan, because of lack of privacy, or because defecation is too uncomfortable.
- 8. Factors affecting Defecationcont.….. Medications • Some drugs have side effects that can interfere with normal elimination. • Some cause diarrhea; others, such as large doses of certain tranquilizers and repeated administration of opioids, cause constipation because they decrease gastrointestinal activity through their action on the central nervous system. • Iron supplements act more locally on the bowel mucosa and can cause constipation or diarrhea. • Some medications directly affect elimination. Ex: Laxatives are medications that stimulate bowel activity and so assist fecal elimination. • Certain medications suppress peristaltic activity and may be used to treat diarrhea. Ex: Imodium
- 9. Factors affecting Defecationcont.….. Diagnostic Procedures • Before certain diagnostic procedures, such as visualization of the colon (colonoscopy or sigmoidoscopy), the client is restricted from ingesting food or fluid. • The client may also be given a cleansing enema prior to the examination. • In these instances normal defecation usually will not occur until eating resumes
- 10. Factors affecting Defecationcont.….. Anesthesia and Surgery • General anesthetics cause the normal colonic movements to cease or slow by blocking parasympathetic stimulation to the muscles of the colon. • Patients who have regional or spinal anesthesia are less likely to experience this problem. • Surgery that involves direct handling of the intestines can cause temporary stoppage of intestinal movement. • This condition, called ileus, usually lasts 24 to 48 hours. • Listening for bowel sounds that reflect intestinal motility is an important nursing assessment following surgery
- 11. Factors affecting Defecationcont.….. Pathologic Conditions • Spinal cord injuries and head injuries can decrease the sensory stimulation for defecation. • Impaired mobility may limit the client’s ability to respond to the urge to defecate and the client may experience constipation. • a client may experience fecal incontinence because of poorly functioning anal sphincters
- 12. Factors affecting Defecationcont.….. Pain • Clients who experience discomfort when defecating (e.g., following hemorrhoid surgery) often suppress the urge to defecate to avoid the pain. • They can experience constipation as a result. • Clients taking opioid analgesics for pain may also experience constipation as a side effect of the medication.
- 13. Fecal Elimination Problems •Four common problems are related to fecal elimination: • constipation • diarrhea • bowel incontinence • flatulence
- 14. Constipation • Defined asfewer than three bowel movements per week. • This infers the passage of dry, hard stool or the passage of no stool. • It occurs when the movement of feces through the large intestine is slow, thus allowing time for additional reabsorption of fluid from the large intestine. • Associated with difficult evacuation of stool and increased effort or straining of the voluntary muscles of defecation. • The individual may also have a feeling of incomplete stool evacuation after defecation. • To define constipation it is important to identify the individual’s regular elimination pattern. • Because some individuals normally defecate only a few times a week; others defecate more than once a day. • Careful assessment of the client’s habits is necessary before a diagnosis of constipation is made.
- 15. Common Characteristics of Constipation •Decreased frequency of defecation • Hard, formed stools • Straining at stool; painful defecation • Reports of rectal fullness or pressure or incomplete bowel evacuation • Abdominal pain, cramps, or distention • Anorexia, nausea • Headache
- 16. Factors contribute toconstipation • Insufficient fiber intake • Insufficient fluid intake • Insufficient activity or immobility • Irregular defecation habits • Change in daily routine • Lack of privacy • Chronic use of laxatives or enemas • Irritable bowel syndrome (IBS) • Pelvic floor dysfunction or muscle damage • Poor motility or slow transit • Neurologic conditions (e.g., Parkinson’s disease), stroke, or paralysis • Emotional disturbances such as depression or mental confusion • Medications such as opioids • Habitual denial and ignoring the urge to defecate
- 17. Diarrhea • Diarrhea refersto the passage of liquid feces and an increased frequency of defecation. • Rapid passage of chyme reduces the time available for the large intestine to reabsorb water and electrolytes. • The individual with diarrhea finds it difficult or impossible to control the urge to defecate. • Often, spasmodic cramps are associated with diarrhea. Bowel sounds are increased. • With persistent diarrhea, irritation of the anal region extending to the perineum and buttocks generally results. • Fatigue, weakness, malaise, and emaciation are the results of prolonged diarrhea. • It can create serious fluid and electrolyte losses in the body. • The irritating effects of diarrhea stool increase the risk for skin breakdown.
- 18.
- 19. Bowel Incontinence • Theloss of voluntary ability to control fecal and gaseous discharges through the anal sphincter. • The incontinence may occur at specific times, such as after meals, or it may occur irregularly. • Fecal incontinence is generally associated with impaired functioning of the anal sphincter or its nerve supply, such as in some neuromuscular diseases, spinal cord trauma, and tumors of the external anal sphincter muscle
- 20. Management of bowelincontinence • modifying the diet (e.g., decreasing alcohol, caffeine, greasy or spicy food, gas-producing vegetables) • Weight loss improves continence by removing weight on the pelvic muscles. Pelvic muscle function is also enhanced by exercises. • A regular defecation schedule can also help • Several surgical procedures are used for the treatment of fecal incontinence. repair of the sphincter and bowel diversion or colostomy
- 21. Flatulence • Three primarysources of flatus (1) action of bacteria on the chyme in the large intestine (2) swallowed air (3) gas that diffuses between the bloodstream and the intestine • Large amounts of gas accumulation in the stomach - gastric distention • Flatulence - presence of excessive flatus in the intestines and leads to stretching and inflation of the intestines (intestinal distention). • It can occur in the colon from a variety of causes, such as foods (e.g., cabbage, onions), abdominal surgery, or opioids. • If the gas is propelled by increased colon activity before it can be absorbed, it may be expelled through the anus. • If excessive gas cannot be expelled through the anus, it may be necessary to insert a rectal tube to remove it
- 22. Nursing Process –[Assessment] • Assessment of fecal elimination includes 1. taking a nursing history 2. performing a physical examination of the abdomen, rectum, and anus 3. inspecting the feces • The nurse also should review any data obtained from relevant diagnostic tests.
- 23. Nursing Process –[Assessment] • DEFECATION PATTERN • When do you usually have a bowel movement? • Has this pattern changed recently? • DESCRIPTION OF FECES AND ANY CHANGES • Have you noticed any changes in the color, texture (hard, soft, watery), shape, or odor of your stool recently? • FECAL ELIMINATION PROBLEMS • What problems have you had or do you now have with your bowel movements (constipation, diarrhea, excessive flatulence, seepage, or incontinence)? • When and how often does it occur? • What do you think causes it (food, fluids, exercise, emotions, medications, disease, surgery)? • What have you tried to solve the problem, and how effective was it? • FACTORS INFLUENCING ELIMINATION • PRESENCE AND MANAGEMENT OF OSTOMY
- 24. Nursing Diagnoses • Constipationrelated to low-fiber diet and inactivity (as evidenced by infrequent, hard stools; painful defecation; abdominal distention) • bowel incontinence r/t……………. • Diarrhea r/t ……………………………… • Potential for decreased fluid volume or potential for altered electrolytes related to prolonged diarrhea • Potential for developing altered skin integrity related to prolonged diarrhea or bowel incontinence • Impaired self esteem related to fecal incontinence • Lack of knowledge (bowel training, ostomy management) related to lack of previous experience.
- 25. Planning • The majorgoals for clients with fecal elimination problems are to: 1. Maintain or restore normal bowel elimination pattern. 2. Maintain or regain normal stool consistency. 3. Prevent associated risks such as fluid and electrolyte imbalance, skin breakdown, abdominal distention, and pain.
- 26. Implementation • Promoting RegularDefecation • Teaching About Medications • Decreasing Flatulence • Administering Enemas • Digital Removal of a Fecal Impaction • Fecal Incontinence Pouch • Bowel Training Programs
- 27. Implementation • Promoting RegularDefecation The nurse can help clients achieve regular defecation by attending to (a) the provision of privacy (b) timing (c) nutrition and fluids (d) exercise (e) positioning
- 28. nutrition and fluids ForConstipation • Increase daily fluid intake, and instruct the client to drink hot liquids, warm water with a squirt of fresh lemon, and fruit juices, especially prune juice. Include fiber in the diet, that is, foods such as raw fruit, bran products, and wholegrain cereals and bread. For Diarrhea • Encourage oral intake of fluids and bland food. Eating small amounts can be helpful because small amounts are more easily absorbed. Excessively hot or cold fluids should be avoided because they stimulate peristalsis. In addition, highly spiced foods and high- fiber foods can aggravate diarrhea. See Client Teaching for details about managing diarrhea. For Flatulence • Limit carbonated beverages, the use of drinking straws, and chewing gum—all of which increase the ingestion of air. Gas-forming foods, such as cabbage, beans, onions, and cauliflower, should also be avoided.
- 29. Positioning • Although thesquatting position best facilitates defecation, on a toilet seat the best position for most individuals seems to be leaning forward • If the patient have difficulty sitting down and getting up from the toilet, an elevated toilet seat can be attached to a regular toilet. A bedside commode, bedpan
- 30. Bowel Diversion Ostomies •An ostomy is an opening for the gastrointestinal, urinary, or respiratory tract onto the skin. • There are many types of intestinal ostomies. • gastrostomy - opening through the abdominal wall into the stomach • jejunostomy - opens through the abdominal wall into the jejunum, • ileostomy - opens into the ileum (small bowel) • colostomy - opens into the colon (large bowel) • Gastrostomies and jejunostomies are generally performed to provide an alternate feeding route. • The purpose of bowel ostomies is to divert and drain fecal material.
- 31. Bowel Diversion Ostomies •Bowel diversion ostomies are often classified according to (a) status as permanent or temporary (b) their anatomic location (c) the construction of the stoma, the opening created in the abdominal wall by the ostomy - single, loop, divided or double-barreled colostomies • A stoma is generally red in color and moist. • Initially, slight bleeding may occur when the stoma is touched and it is considered normal. • The client does not feel the stoma because there are no nerve endings in the stoma
- 33. anatomic location • Thelocation of the ostomy influences the character and management of the fecal drainage. • An ileostomy produces liquid fecal drainage • A descending colostomy produces increasingly solid fecal drainage.
- 34. Ostomy Management Nursing Interventionsinclude, • Physical interventions of stoma assessment • Application of an appliance to collect feces and protect skin • Promotion of self-care
- 35. Ostomy Management cont.…. DietaryConsiderations • Stomal blockages can be avoided by informing clients to chew well and increase their hydration. • The usual changes in diet are focused on minimizing gas and odor. • Foods that produce gas include broccoli, carbonated liquids, and alcohol. • Odor-producing foods include onions, vegetables, eggs, and fish. • Foods that provide a natural deodorizer include yogurt, parsley, and buttermilk
- 36. Ostomy Management cont.…. Stomaand Skin Care • Care of the stoma and skin is important for all clients who have ostomies. • The fecal material (effluent) from a colostomy or ileostomy is irritating to the peristomal skin, with the resulting moisture-associated skin damage being the most common cause of peristomal skin problems. • This is particularly true of stool from an ileostomy, which contains digestive enzymes.
- 37. Stoma and SkinCare cont.…. • Any irritation or skin breakdown needs to be treated immediately. • The skin is kept clean by washing off any excretion with water and drying thoroughly. • If soap is used, it should not contain cream or lotion that may leave a residue, which can interfere with the skin barrier adhesive.
