Ineffective Bowel Elimination-Diarrhea
Passage of blank or more loose stools/day indicates diarrhea.
How many days for acute, persistent, & chronic diarrhea?
3
Acute: 14 days or less
Persistent: more than 14 days
Chronic: more than 30 days
Ineffective Bowel Elimination-Diarrhea
What are 2 ways diarrhea is transmitted?
- Contaminated food or water
- Fecal-oral route
Ineffective Bowel Elimination-Diarrhea
What is the primary cause of diarrhea?
Infectious organisms
Ineffective Bowel Elimination-Diarrhea
What are some factors that makes one susceptible to diarrhea?
Age—older adult
Gastric acidity—proton pump inhibitors decrease stomach acid; organisms survive
Intestinal microflora—microbial barrier altered by antibiotics
* C. difficile infection (CDI)—most serious antibiotic—associated diarrhea
Immune status—immunocompromised due to disease or jejunal enteral feedings
Diarrhea - Manifestations
What are some common Upper GI tract, Lower GI tract, & Severe diarrhea manifestations?
Upper GI tract: Large-volume, watery stools; cramping, periumbilical pain; preceding nausea and vomiting; low grade or no fever
Lower GI tract: Small-volume bloody diarrhea; fever
Severe diarrhea: Dehydration (life-threatening), electrolyte imbalances (K+), and acid-base imbalances (metabolic acidosis)
Stool may contain leukocytes; blood, or mucus
C. Diff.—colitis and intestinal perforation
Diarrhea - Diagnostic Studies
What are the 7 diagnostic studies for diarrhea?
- Stool cultures—blood, mucus, WBCs, infectious organisms
- Blood cultures—sepsis or immunocompromised
- WBCs
- Anemia from iron and folate deficiencies
- BUN, creatinine ,electrolytes, pH, osmolality
- Stool fat, protein
- GI hormones
Diarrhea - Interprofessional Care
How is diarrhea treated?
Treatment: depends on cause
* Prevent transmission
* Replace fluid and electrolytes (Oral or IV)
* Protect the skin
* Antidiarrheals
Diarrhea - Interprofessional Care
What are the goals of diarrhea care?
- Cessation of diarrhea and resumption of normal bowel patterns
- Normal fluid, electrolyte, and acid-base balance
- Normal nutritional status
- No perianal/perineal skin breakdown
Diarrhea
What are some key nursing implementations for diarrhea?
- Consider all to be infectious until cause is known
- Meticulous hand hygien (soap & water)
- Flush vomitus & stool in toilet
- Teach pt. & caregiver
Diarrhea
What should the nurse teach the pt./caregiver about diarrhea?
- Principles of hygiene, infection control precautions, potential dangers of infectious illness; proper food handling, cooking and storage
- CDI—Isolation; gown and gloves for everyone
- Disinfect with 10% bleach or C.difficile sporicidal
Clostridium difficile Infection (CDI)
What is C.Diff and who is at risk?
Health care–associated infection (HAI)
Patients at risk: those receiving antimicrobial, chemotherapy, gastric acid-suppressing, or immunosuppressive agents
C. difficile spores—survive up to 70 days
Clostridium difficile Infection (CDI)
What kind of precautions are used for C.diff and what prophylaxis/adjunct therapy is used?
Contact precaution
* Strict infection control precautions
* Hand washing with soap and water
Prophylaxis or adjunct therapy—lactobacillus
* Given four times a day
CDI
What is the treatment for C.diff
Oral vancomycin or fidaxomicin for 10 days
* Alternate: metronidazole
* Complicated: vancomycin and IV metronidazole
* Ileus: vancomycin via enema
Stop nonessential antibiotics, stool softeners, laxatives, and antidiarrheals
Recurrent: fecal microbiota transplantation (FMT)
* Donor feces administered via enema, nasoenteral tube or colonoscopy; Concern: transmission of infection
Ineffective Bowel Elimination - Fecal Incontinence
What is the etiology & pathophysiology for fecal incontinence?
Involuntary passage of stool related to motor and/or sensory dysfunction.
Ineffective Bowel Elimination - Fecal Incontinence
What diagnostic studies are performed for fecal incontinence?
History and Physical (H&P)
Rectal examination
Anorectal manometry, ultrasound, or electromyography
Fecal Incontinence - Nursing Implementation
When is the best time to schedule elimanation for bowel training programs? What should be done if bowel training is ineffective?
30 minutes after breakfast
If ineffective:
* Administer bisacodyl, glycerin suppository, or small enema to stimulate anorectal reflex until pattern established
* Digital stimulation
* Tap water irrigation
Constipation
What are some characteristics of constipation? When is it acute/chronic?
- Difficult or infrequent bowel movements
- May require excessive exertion to defecate
- Feeling of incomplete evacuation
- Symptom, not a disease
Acute—less than 1 week
Chronic—greater than 3 months
Constipation
What are some risk factors of constipation?
Low-fiber diet
Decreased physical activity
Ignoring urge to defecate
Emotions, anxiety, depression
Constipation
What are some disease and drugs that induced constipation?
- Colonic:Affecting the colon (large intestine).
- Neurologic: Affecting the nervous system
- Systemic: Affecting the entire body
- Collagen vascular: Affecting connective tissue & blood vessels
Drug-induced - Opioids
- Cathartic colon syndrome
- Chronic laxative use results in dilated, atonic colon
Constipation - Interprofessional Care
What are some ways constaption is treated?
- Lifestyle Modifications (First-Line Approach: increase dietary fiber, fluid, & exercise
- Pharmacological Interventions: laxatives, enemas, & peripherally acting opioid receptor antagonists
- Other Interventions:
- Biofeedback: Helps patients learn to coordinate their pelvic floor muscles to improve bowel function.
- Colostomy, Ileostomy, Continent Fecal Diversion:
Constipation - Interprofessional Care
What are some nutritional therapy interventions/care for constipation?
- Dietary Fiber: Emphasizes the importance of incorporating fiber-rich foods like vegetables, fruits, and grains into the diet.
- Adequate Fluid: Reinforces the need for sufficient fluid intake (2 liters per day).
- Probiotics: May help improve gut health and regularity, although more research is needed.
