- Pain control
- IV fluid therapy

post-operative complications following surgery to correct peptic ulcer disease (PUD)

- dumping syndrome
- post-prandial hypoglycemia
- bile reflux gastritis

dumping syndrome

a condition whereby food moves too rapidly from the stomach into the small intestine; may see post-prandial hypoglycemia because rush of insulin is released to try to counteract bolus of chyme

S/S dumping syndrome

post eating weakness, sweating, palpitations, dizziness, abdominal cramps, borborygmi, urge to defecate

treatment for dumping syndrome

- usually self limiting
rest and reassurance
- best diet to decrease hyperosmolor composition and amount of chyme is 6 small dry feedings
- avoid fluid with meals
- low refined sugar
- low CHO
- moderate fat and PRO
-lay down after eating for 30 minutes (

post-prandial hypoglycemia

variant to dumping syndrome; bolus of high CHO fluid into small intestine results in excessive insulin secretion

S/S of post-prandial hypoglycemia

Secondary hypoglycemia 2 hours after eating, usual S/S

interventions for post-prandial hypoglycemia

treat hypoglycemia (increase blood sugar with carbs or glucagon), same diet interventions as dumping syndrome

bile reflux gastritis

a disabling postgastrectomy condition characterized by abdominal pain, bilious vomiting, and weight loss. The syndrome appears to be caused by free enterogastric reflux of bile and other proximal small bowel constituents

danger of bile reflux gastritis

can cause ulcer recurrence

treatment of bile reflux gastritis

two forms of inflammatory bowel disease (IBD)

1. Crohn's disease
2. Ulcerative colitis

common characteristics of inflammatory bowel disease

- Chronic illnesses with alternating periods of exacerbations and remissions
- Characterized by recurrent inflammation of the intestinal tract, diarrhea, and abdominal pain
- Extraintestinal manifestations common

Who is at high risk for inflammatory bowel disease (IBD)?

- Most commonly diagnosed in adolescents and young adults
- Highest rates among North Americans and Northern Europeans
- Etiology Unknown, many speculations
- Suspected genetic predisposition

disease distribution: Crohn's disease (CD) and ulcerative colitis (UC)

CD: disease can be anywhere in the GI tract; however, it is most commonly seen in distal small intestine
UC: disease limited to the colon (large intestine)

inflammation: Crohn's disease (CD) and ulcerative colitis (UC)

CD: skips lesions that affect all layers of the bowels
UC: travels from rectum upwards (mostly mucosa layer damaged)

In which IBD do we typically see more weight loss and malnutrition?

more common in Crohn's because the damaged small intestine is where nutrients are typically absorbed

carcinogenesis with IBD

increased risk of cancer in both Crohn's and ulcerative colitis

surgery: Crohn's disease (CD) and ulcerative colitis (UC)

CD: try not to perform surgery with Crohn's because it is a progressive condition in which it is important to maintain as much healthy bowel as possible (can't afford to be taking out portions of the bowel); if surgery performed, elevated risk of short bo

Strictures, fistula, and perianal disease: Crohn's disease (CD) and ulcerative colitis (UC)

CD: strictures more commonly seen because all layers of GI tract affected
UC: toxic megacolon

fistula

abnormal passageway between two organs or between an internal organ and the body surface

significance of fistula

- If infected fistula perforates into abdominal cavity, it may lead to sepsis
+ Immediate surgery may be necessary
+ May require temporary colostomy

Fistulous disease of ano-perineal area

+ drainage and stool may seep through fistula in between bowel movements
+ May lead to social isolation
+ May require temporary colostomy

toxic megacolon

complication in which the colon dilates and becomes atonic and vulnerable to perforation; seen more commonly with ulcerative colitis

extra-intestinal manifestations of inflammatory bowel disease (IBD)

- Mouth: Aphthous ulcers
- Musculoskeletal: Arthritis/arthralgias, Ankylosing Spondolytis (arthritis of the spine), Osteoporosis
- Liver: Primary Sclerosing Cholangitis
- Skin: Erythema Nodosum (red lumps on skin), Pyoderma Gangrenosum, Perianal lesions
-

episcleritis

looks like pink eye but not drainage; inflammation of the outermost layers of the sclera

pyoderma gangrenosum

deep ulcerative cutaneous condition, unknown etiology, poor wound healing; seen with inflammatory bowel disease

Does ulcerative colitis surgery resolve extra-intestinal manifestations of condition?

no

common nursing diagnoses for inflammatory bowel disease

- Biological therapy
- Antimicrobials

function of aminosalicylates in IBD patients

To induce and/or maintain a remission in mild to moderate disease by controlling inflammation

types of aminosalicylates

1. With sulfapyridine (azulfadine): component that helps the medication travel to where it needs to be; however, it has side effects
2. Without sulfapyridine (mesalamine, olsalazine, balsalazide): newer agents

How are aminosalicylates delivered?

- Acts locally
- PO, suppository, enema forms

function of corticosteroids in IBD patients

used to induce a remission (given for short-term use)

types of corticosteroids given to IBD patients to induce a remission

- Oral Prednisone (need to take with calcium supplements)
- IV steroids (methylprednisolone)
- Budesonide (has high local activity if there is a growth concern)

function of immune modulators in IBD patients

to maintain remission after corticosteroids are administered (more of a long-term option) for severe disease

types of immune modulators used in IBD patients

- 6-mercaptoprine
- Azathioprine
- Methotrexate (not helpful for U.C.)

care management of IBD patient taking immune modulators

- Monitor blood counts (may cause bone marrow suppression)
- Increased risk of infection
- Encourage fluids (to protect kidneys)
- Not immediately effective

function of biological therapy for IBD patients

Used to induce and/or maintain remission in moderate to severe disease (used in combination with immune modulators); therapy is costly and puts patient at an increased risk for infection

What is it important to remember when administering biological therapy?

-Have to check for latent TB, hepatitis, and opportunistic cancer before administration
- Immunogenic: do not discontinue then restart (if you start and stop, the body may produce antibodies against therapy, causing a reaction if restarted)

What additional medications may be needed if disease in the terminal ilium?

Cobalamin
Cholestyramine

goals of nutritional management in IBD patients

Goals are (1) to provide adequate nutrition without exacerbating symptoms, (2) to correct and prevent malnutrition, (3) replace fluid and electrolyte losses, and (4) to prevent weight loss.

diet therapy for IBD patients

- Low in residue, roughage, and fat; high in calories and protein, with vitamin and iron supplements
- Milk and milk products may need to be excluded
- Elemental diet may be needed during acute exacerbations and can be used to assist in maintaining remiss

characteristics of a low residue diet

Avoid the following:
- Whole grains
- Raw and dried fruits
- Raw and cruciferous vegetables
- Nuts, seeds, beans and lentils

characteristics of elemental diet

high in calories and nutrients; lactose-free; it is usually composed of amino acids, fats, sugars, vitamins, and minerals

function of total parenteral nutrition in IBD patients
