Q

Causes of IBD

A

exact cause is unknown but has been linked to genetic predisposition, environmental conditions, and defects in immune regulation

  • the genetic predisposition may manifest as an overactive immune response to bacteria located in the GI Tract; it may then be triggered by an environmental response such as infection, medication, or smoking
  • whereas the immune system usually attacks foreign invaders, in people with IBD, the immune response has an inappropriate response in the intestinal tract causing inflammation; this inflammation affects the ability to absorb nutrients resulting in diarrhea and weight loss in some patients

Q

Crohn’s Disease

A

can affect any portion of the GI tract from mouth to anus, but more common in terminal ileum and colon
-affects small bowel and malabsorption is most common in this disorder
-it is transmural, affecting all layers of the bowel
-not uniform in appearance, noted for having skip lesions with normal-appearing bowel between lesions
-the lesions cause deep ulcerations between layers of edematous tissue, creating a cobblestone appearance
-with each exacerbation, the intestine becomes more scarred, which then leads to less ability to absorb nutrients
-diarrhea is less severe than in ulcerative colitis
-stools are typically soft or semiliquid and do not usually contain blood unless there has been a perforation
-nutritional deficits arise from the inability to absorb nutrients, and electrolyte disturbances are common
-abdominal pain is usually worse in the RLQ
>no known cure for Crohn’s disease

Q

Because Crohn’s Disease is transmural, what complications does this lead to?

A

it may actually penetrate the bowel wall, leading to complications such as fistulas, abscesses, and peritonitis
-strictures and adhesions are also common

Q

Ulcerative Colitis

A

affects the large intestine and involves only the mucosa and submucosa
-disease spreads uniformly beginning at the rectum and spreading upward toward the cecum
-diarrhea is common, often with more than 20 stools per day with losses of several liters of fluid per day
-blood, mucus, and pus are common with ulcerative colitis
-abdominal pain and tenderness that is worse in the LLQ
-patients may manifest tenesmus; which involves spasms of the anal sphincter and persistent desire to empty the bowel
-a lesion called a crypt abscess releases secretions that result in a purulent discharge from the bowel mucosa
-abscesses may form in ulcerated areas
-scar tissue is common, interfering with absorption of nutrients
>total colectomy is surgical cure for ulcerative colitis

25
What is used in the diagnosis of both Crohn's disease and Ulcerative Colitis?
colonoscopy, sigmoidoscopy, and barium enema
26
Colonoscopy Findings
assist in differentiating Crohn's disease and ulcerative colitis - Crohn's disease: the colonoscopy detects early mucosal changes including inflammation, stricture, and fistulae - Ulcerative Colitis: swollen, friable bowel mucosa with multiple ulcerations
27
Barium Enema Findings
may provide data regarding the depth of the disease involvement
28
Besides a colonoscopy, sigmoidoscopy and barium enema, what other diagnostic tests can you include?
CBC, serum electrolytes, serum albumin, and stool samples for pathogens
29
What type of management is crucial for the patient with Ulcerative Colitis?
Fluid and electrolyte management -when the bowel is inflamed, and the patient is exhibiting severe diarrhea, absorption of fluids and nutrients is compromised >patient is encouraged to rest frequently to decrease bowel motility
30
Nutrition: Malnutrition
malnutrition is common with IBD and can lead to many other complications such as poor wound healing, decreased muscle mass, and a decreased immune system -more common in Crohn's disease because it affects mostly the small bowel
31
Nutritional abnormalities can be caused by?
malabsorption, decreased food intake, medications, and/ or intestinal losses >patient may need to be hospitalized for bowel rest and receive total parenteral nutrition (TPN)
32
What may be necessary in patients with Crohn's disease who have the inability of the ileum to absorb this nutrient?
monthly B12 injections
33
Nutritional Deficits
zinc, potassium, magnesium, and vitamins >liquid vitamin preparations are usually necessary because tablets or capsules may be excreted intact because of the frequency of diarrhea -vitamin b12 injections may be necessary for patients with Crohn's disease
34
Albumin Levels
frequently used to determine nutritional status, but other factors may alter albumin levels such as inflammation, infection, or cancer
35
Foods to Avoid
milk, gluten, caffeine, cocoa, chocolate, citrus juices, cold or carbonated drinks, nuts, seeds, popcorn, and alcohol
36
Complementary and Alternative Medicines
patients often reluctant to mention this to provider for fear of being judged - marijuana, turmeric and curcumin, fish oil, probiotics, aloe Vera, Androphigus paniculata (e.g. India echinacea), Boswellia (e.g. frankincense), Tripterygium wilfordii Hook F (thunder god vine), wheat grass, and wormwood - acupuncture, moxibustion, mind-body therapies, and exercise
37
Exacerbations of IBD may occur when?
during times of emotional or physical stress -patients with IBD are concerned with how others view them; there may be a perceived, or actual, loss of independence, sense of control, privacy, body image, healthy self, peer relationships, self-confidence, productivity, and ways of expressing sexuality, therefore increasing risk of depression
38
Surgical Management: Crohn's disease
- Crohn's disease: is reserved for patients when medical management has failed and/ or who experience complications from the disease like strictures, abscesses, intestinal obstruction, perforation, hemorrhage, or cancer. - when a diseased portion of the bowel is removed, it frequently recurs in another section of the bowel; surgery does not cure Crohn's disease
39
Surgical Management: Ulcerative Colitis
for whom medical management has failed or who have experienced complications may undergo a colectomy and be cured of the disease but not of the extra-intestinal manifestations >standard procedure: is an ileal pouch anal anastomosis (IPAA); the entire colon and rectum are removed, a pouch is created to collect waste, and the patient is able to defecate normally
40
Standard Procedure In surgical Management of Ulcerative Colitis
Ileal Pouch anal anastomosis (IPAA) -the entire colon and rectum are removed, a pouch is created to collect waste, and the patient is able to defacate normally
41
Proctocolectomy with permanent ileostomy
patients with ulcerative colitis may undergo this procedure - includes the removal of the colon and rectum and permanent closure of the anus - the ileostomy is permanent
42
Proctocolectomy with a Kock or Koch Pouch
a continent ileostomy - patients with ulcerative colitis - a portion of the ileum is used to create a reservoir that can be catheterized to remove stool
43
Complications
- perineal abscesses and fistulas occurs in patients with Crohn's disease - strictures and fistulas more common in Crohn's disease - intestinal obstruction occurs secondary to inflammation and edema - fibrosis and scarring over time may also cause narrowing of the bowel, leading to an obstruction - malnutrition frequently develops because of malabsorption of nutrients, severe diarrhea, and anorexia due to the fear that eating may cause an exacerbation of symptoms - anemia from hemorrhage and malnutrition may lead to patients needing blood transfusions and patients are often prescribed iron supplements to treat anemia
44
Extraintestinal Complications
- joint swelling and pain - ankylosing spondylitis - osteoporosis - kidney stones - eye inflammation - mouth sores - skin lesions
45
During Inflammation, what may the patient experience?
- fever - anorexia - and malaise
46
Anal Fissures
tears in the anal wall | -develop secondary to severe bouts of diarrhea
47
Surgical Complications
anal canal strictures, pelvic sepsis, pouch failure, fecal incontinence, pouch dysplasia/cancer, sexual dysfunction, and female infertility
48
Chronic Pouchitis
complication associated with the IPAA procedure | -one probiotic preparation may be effective in the prevention of recurrent pouchitis (VSL #3)
49
Fistulas
more common in Crohns Disease -can often cause other complications such as sepsis, skin irritation, and malnutrition, dehydration, and fluid and electrolyte imbalances >Enterocutaneous Fistula (between skin and intestine) >Enteroenteral Fistula (between intestine and intestine) >Enterovesicular Fistula (between bowel and bladder) >Enterovaginal Fistula (between bowel and vagina)
50
Skin Irritation and Excoriation often occur because of what?
intestinal secretions being rich in enzymes; protection of the skin is of utmost importance -skin may become in contact with secretions through fistulas and ostomies (surgical openings in an organ), such as an ileostomy (opening in the ileum) and colostomy (opening in the colon) > the anus can also become irritated from frequent diarrhea
51
Toxic Megacolon
colonic dilation of greater than 5 cm - occurs more frequently in ulcerative colitis and requires emergency colectomy - bacterial overgrowth contributes to toxic megacolon
52
Short Bowel Syndrome
can occur if more than 100 cm of small bowel is removed because absorption is greatly affected - the jejunum is where most carbohydrate and protein absorption takes place, and the ileum is where absorption of fats, fat-soluble vitamins, and b12 takes place; if the jejunum is removed, the ileum assumes the function of fat absorption; the removal of the ileum accounts for more complications because it is responsible for the absorption of fats, vitamins, bile salts, and B12 - patients having 50% to 70% of the small intestine removed experience malabsorption but can usually be managed with dietary supplementation
53
Narcotic Bowel Syndrome
characterized as chronic, intermittent, and cramping abdominal pain associated with the effects of the narcotic analgesic wearing off
54
Nursing Management: Assessment and Analysis
assessment of intake and output and daily weight s will help determine nutritional status of patients with suspected IBD - frequent diarrhea leads to extreme losses of fluids and potassium, or hypokalemia - patients with IBD are often victims of social isolation because of the fear of incontinence in public or having the need to be close to a bathroom at all times - patients with IBD often report exacerbations as related to a stressful event - clinical manifestations: persistent diarrhea, abdominal pain or cramps, fever, weight loss, fluid imbalances, mouth ulcers, anemia, melena, - extraintestinal manifestations: uveitis, sclerosing cholangitis, nephrolithiasis, cholelithiasis, joint disorders, and skin disorders
55
Nursing Diagnoses
- Deficient fluid volume r/t diarrhea - Diarrhea r/t intestinal inflammation and malabsorption of nutrients - Imbalanced nutrition: less than body requirements r/t inability to absorb nutrients secondary to inflammation - Ineffective coping r/t chronic disease
56
Nursing Interventions: Assessment
- vital signs - nutritional intake - frequency and characteristics of stools and note any presence of blood - intake and output - daily weight - fluid and electrolyte status - psychosocial assessment and support systems
57
Assessment: Vital Signs
with significant fluid loss, the patient may develop signs of decreased fluid volume including a low-grade fever, elevated heart rate, and decreased blood pressure
58
Assessment: Nutritional intake
assisting the patient to maintain a intake diary will assist in monitoring nutritional status -frequent diarrhea is associated with malabsorption of nutrients
59
Assessment: Frequency and characteristics of stools and note any presence of blood
excessive losses result in complications such as fluid and electrolyte imbalances -blood may be noted in the stool of the patient with ulcerative colitis but is unusual in Crohn's disease
60
Assessment: Intake and Output
patients often do not attempt to eat or drink in fear of exacerbating clinical manifestations -urine output should be monitored for at least 30 mL/hr to provide information regarding renal perfusion
61
Assessment: Daily Weight
weight is the best measurement for nutritional needs
62
Assessment: Fluid and Electrolyte Status
patients tend to loose many electrolytes through diarrhea, particularly potassium and magnesium
63
Assessment: Psychosocial Assessment and support systems
the patient frequently is a victim of social isolation because of fears of incontinence and/or frequent trips to the bathroom
64
Nursing Actions
- encourage smaller frequent meals - encourage the patient to engage in mealtimes with family - encourage periods of rest - establish a therapeutic relationship - make appropriate referral to interprofessional team - pain management - provide meticulous skin care
65
Actions: Encourage smaller frequent meals
decreases gastric motility
66
Actions: encourage periods of rest
help decrease gastric motility and conserve energy
67
Actions: Establish a therapeutic relationship
helps develop trust between patient and healthcare provider
68
Actions: Make appropriate referrals to interprofessional team
inflammatory bowel disease is a complex disease and requires a team approach including a case manager, dietician, and any local support group
69
Actions: Pain Management
positioning and maintaining a quiet environment may promote comfort -pain medications may be ordered; if administered monitor for side effects like constipation
70
Actions: Provide meticulous skin care
having frequent diarrhea needs special attention to the rectal area because the feces contain enzymes that may cause excoriation to the skin surrounding the anus
71
Teachings
- importance of adequate nutrition - indications, actions and side effects of prescribed medications - importance of regular follow-ups and annual colonoscpy
72
Teachings: Importance of adequate nutrition
malnutrition due to malabsorption is common with IBD - adequate nutrition is required for healing and maintaining a stable weight - a daily multivitamin may be prescribed, but vitamins with iron may be controversial due to poor tolerance and may worsen symptoms - reducing fiber and fat intake during exacerbation, drinking plenty of fluids, and avoiding milk and milk products during exacerbations are important
