Cards (94)

  • CONSTIPATION
    • Fewer than three bowel movements weekly
    or bowel movements that are hard, dry,
    small or difficult to pass.
    • Is a symptom, not a disease.

    • Lack of exercise
    • Stress
  • Classes of Constipation
    • Functional Constipation- normal transit mechanism of mucosal
    transport.
    • Slow-transit constipation- caused by inherent disorders of the motor
    functions of the colon, characterized by infrequent bowel
    movements.
    • Defecatory disorder- caused by dysfunctional motor coordination
    between the pelvic floor and anal sphincter.
  • Pathophysiology of Constipation

    1. The urge to defecate
    is ignored.

  • PERITONITIS
    Inflammation of the peritoneum, which is the serous membrane
    lining the abdominal cavity and covering the viscera.
  • Categories of Peritonitis
    • Primary
    Peritonitis
    (Spontaneous
    Bacterial
    Peritonitis)-
    Spontaneous bacterial infection of ascitic fluid.
    • Secondary Peritonitis- secondary to perforation of abdominal
    organs with spillage that infects the serous peritoneum.
    • Tertiary Peritonitis- result of a suprainfection in a patient who is
    immunocompromised.
  • Pathophysiology of Secondary Peritonitis
    1. Inflammation,
    Infection, Ischemia,
    Trauma or tumor
    perforation
    2. Leakage of contents
    from abdominal
    organs into the
    abdominal cavity
    3. Bacterial
    proliferation occurs
  • Assessment of Peritonitis
    • Diffused pain then becomes constant, localized and more intense
    • Pain aggravates by movement

    • Fever 37.8-38.3C, increased PR
    • Hypotension
    • Manifestation of septic shock and sepsis
  • Diagnostic Findings for Peritonitis
    • Elevated WBC (increased neutrophils)
    • Low hgb and hct if with blood loss.
    • Altered S. electrolyte levels (K, Na, Cl)
    • Abd. Xray- may show air and fluid levels as well as distended bowel
    loops
    • Abd. UTZ reveal abscesses and fluid collection
  • Serous peritoneum
    The outermost layer of the peritoneum
  • Tertiary Peritonitis
    Result of a suprainfection in a patient who is immunocompromised
  • Pathophysiology: Secondary Peritonitis
    1. inflammation, infection, ischemia, trauma or tumor perforation
    2. leakage of contents from abdominal organs into the abdominal cavity
    3. bacterial proliferation occurs

    • MRI may be used for diagnosis of intra-abdominal abscess
  • Medical Management of Secondary Peritonitis
    1. Fluid, colloid and electrolyte replacement
    2. Analgesic medication- pain
    3. Antiemetic- N&V
    4. Intestinal intubation and suction
    5. O2 therapy
    6. Antibiotic therapy (broad-spectrum antibiotic)
    7. Surgical treatment – excision, resection without anastomosis, repair and drainage
  • Nursing Management of Secondary Peritonitis
    1. Intensive care and monitoring
    2. Assess for subsiding peritonitis signs (decrease in temp., PR, softening of the abd., return of peristaltic sounds, passing of flatus and bowel movements)
    3. Increase fluid and food intake gradually
    4. Reduce parenteral fluid as prescribed
    5. Worsening clinical condition may indicate complication- PREPARE PATIENT FOR EMERGENCY SURGERY!!!
