INTERFERENCES WITH ELIMINATION

CONGENITAL OBSTRUCTIVE INTERFERENCESAnorectal MalformationsDefinition: malformation of anus and/or rectum minor to severe forms-rectal atresia -imperforate anus

Assessment May Include:

- failure to pass meconium stool ( imperforate anus)

- stools in urine ( fistula)

- ribbonlike stools (anal stenosis)

Inspection of perineal area for abnormalities

Insert lubricated rectal thermometer short distance(check protocol of agency)

Interventions- corrective surgery (anoplasty)- perform manual dilation as ordered- instruct parents in proper technique- prevent infection keeping anal area as clean as possible

HIRSCHSPRUNGS DISEASE:AGANGLIONIC MEGACOLON

Definition/Pathophysiology autonomic parasympathetic ganglion cells absent in part of the large colon resulting in decreased motility, causing mechanical obstruction

-familial disease, more common in boys and associated with Down’s syndrome

Diagnosis: - history of bowel patterns

- radiographic contrast studies

- rectal biopsy to check for ganglion cells

AssessmentNewborns: failure to pass meconium, refusal to suck, abdominal distention and bile stained emesisOlder Child: failure to gain weight and delayed growth, abdominal distention, constipation alternating with diarrhea and vomiting

Treatment/InterventionsSurgical removal of aganglionic bowel with a temporary colostomy (in severe cases)

Milder case: dietary modification ( low residue), stool softeners-isotonic irrigations to prevent impactions

Nursing ManagementIdentify early through history

Monitor fluid & lyte balance; nutrition

Patient education- teach ostomy care if needed- teach how to perform irrigations- teach how to prevent skin breakdown- teach proper nutrition

Post op care/measures: monitor for infection,pain control, measure abdominal circumference,maintain hydration

VOLVULUS

Definition/Pathophysiology: bowel twists upon itself causing obstruction and necrosis

Assessment: nausea, vomiting, no bowel sounds,severe gripping pain and a tense distended abdomenConfirmed by x-ray

Treatment/Interventionssurgical intervention with a bowel resection follow with post op care

INTUSSUSCEPTIONDefinition/Pathophysiology:

- telescoping of the bowel into itself

- usually at the ileocecal valve

- causes inflammation and edema

-blood flow becomes decreased

- commonly in boys (2 months to 5 yrs old) -associated with cystic fibrosis and celiac disease

Assessment: abrupt onset with acute abdominal pain, vomiting and the passage of brown stool

- as condition worsens stools become red andresemble currant jelly

- possibly a palpable mass in R upper quadrantor mid upper abdomen

Diagnosis: history of child and radiography, ultra-sound of abdomen and/or barium enema

Treatments

-Barium Enema can reduce telescoping by hydro-static pressure

-Surgery to reduce invaginated bowel and removenecrotic tissue

Nursing Management for Intussusception

IV’s started immediatelyPost Op -monitor VS, bowel sounds -monitor abdominal distention -check for S&S of infection-manage pain- maintain NGT patencyPATIENT EDUCATION

Omphalocele Definition/Pathophysiology: -congenital malformation where intra- abdominal contents

herniate through the umbilical cord -covered by translucent sac-peritoneum

-may have other congenital anomalies

Nursing Management-cover with NS soaked gauze & cover with plastic-monitor VS especially temp-NPO with IV’s to maintain fluid & lyte balance

Post Op Care

prevent infection

maintain fluid & lytes

control pain

ensure adequate nutritional intake

support parents in dealing with crisis

Hernias Definition: -protrusion of viscus from its normal

cavity through an abnormal openingTypes: Reducible: can be manually placed back into

abdominal cavity

Irreducible: cannot be placed back into cavity

Inguinal: weakness of abdominal wall- spermatic cord emerges in males- round ligament in females

Strangulated: irreducible with blood flow cut off

Treatment/Interventionsmanual reductionuse of supports (TRUSS)surgery for strangulated hernia repair

Nursing Interventions -Post op prevent bladder distention splint incision site deep breathe Q 2 HR (avoid coughing) ice to scrotal area & support avoid heavy lifting 4-6 weeks report pain or difficulty urinating

INFLAMMATORY INTERFERENCES

Necrotizing Enterocolitis -inflammatory disease of the intestinal tract r/t intestinal ischemia, infection, gut immaturity - primarily in premature infants

Assessment -feeding intolerance ( vomiting, abdominal distention, irritability)

-bloody diarrhea - possible sepsis

Diagnostics-X-rays showing free peritoneal gas-bowel wall thickening

Interventions: - NPO and maintain IV’s - NGT to suction - antibiotics

- bowel resection- possible ileostomy, colostomy

NURSING MANAGEMENT

• ID early (monitor feedings)• Maintain fluid & lyte balance• Comfort infant (holding, pacifier to meet

sucking needs)• Patient Education post op

APPENDICITISDefinition

- inflammation of the vermiform appendix preventing mucus from passing into the cecum

-untreated can cause ischemia, gangrene, rupture and peritonitis (may be caused by mechanical obstruction or anatomical defect)

Assessment - low grade fever - Rt. Lower quadrant pain (McBurney’s point) - vomiting, diarrhea, constipation

- rebound tenderness - Rovsing’s sign: palpate Lt. abdomen, pain felt on Rt.

Diagnostics - increased WBC count - CAT scan

TREATMENTS/INTERVENTIONS

Pre Op Post OpNPO check VS, monitor incisionIV’s IV’sAntibiotics antibioticsNGT (if peritonitis) coughing & deep breathingNo laxatives drain (penrose) if ruptured

Ruptured Appendix - fever - sudden relief of pain

-chills, pallor

NURSING MANAGEMENT-Promote comfort: Rt. Side lying, semi- fowler’s with knees bent, analgesics-Maintain hydration: I&O, skin turgor-Support respiratory function: cough, deep breathe / splint-Check for S&S of infection:

check incision, check drainage, change dressing, antibiotics

(deep fissures & ulcerations may develop between loops of bowel or nearby organs) - possible genetic association

Assessment - crampy abdominal pain (RLQ) - fever - diarrhea (weight loss )

- ileum involvement ( steatorrhea)

(prevalent in individuals of Jewish descent between the ages of 15- 25 yrs. old )

Diagnostics

- CBC: increased WBC, decreased H&H - increased ESR

- hypoalbumineria- abdominal tenderness- thrombocytosis- radiologic & biopsy examination- lower endoscopy (proctosigmoidoscopy)- barium study of UGI tract- CAT scan

ULCERATIVE COLITIS

Definition -chronic disease of colon/rectal mucosa

- can involve entire length of bowel -only involves mucosa/submucosa with ulcerations & inflammation

- emotional/psychosocial factors may have an effect-peak incidence 15 – 25 yrs & 55- 65 yrs. Old F>M

Assessment- bloody/mucus diarrheal stools- lower abdominal pain (cramping) -tenesmus- wt. loss (possible delayed growth & arthralgias)- ID nutritional deficiencies

Diagnostics -ID the extent of involved bowel - r/o any infectious process

(i.e. Shigella) - radiologic studies & endoscopy

with biopsy - decreased H&H, albumin -increased WBC

Treatment/ManagementMedications Salicylate Compounds: Sulfasalazine Corticosteroids: prednisone Immunosuppressants: cyclosporine Antidiarrheals: immodium Antibiotics : ciprofloxacilNutrition Therapy - low fiber diet - if poor appetite (high protein) -supplemental vitamins, iron, zinc & folic acid -TPN

GASTROENTERITIS (ACUTE DIARRHEA)Definition

- inflammation of the stomach and intestines

-may be accompanied by vomiting and diarrhea (bacterial or parasitic infections)Assessment

-mild, moderate or severe diarrhea (loose, watery stools) - irritabilty, cramping - nausea and vomiting - fluid & lyte balance - hx & physical exam of patient - stool examination (ova and parasite)

Treatments/Interventions-ID the causative factor-moderate: maintain fluid & lytes balance-oral replacement therapy

(pedialyte, gatorade) -no carbonated or sugar drinks

-severe: keep NPO; give IV fluids (NS/ RL) - start with clear liquids - monitor lytes especially potassium for

cardiac patients - antidiarrheals for adults

Nursing Interventions -Provide emotional support : allow pt. to talk

-Provide rest and comfort: quiet environment-Ensure adequate nutrition: BRAT diet

(bananas, rice, applesauce & toast)CRAM (complex carbohydrates

rice and milk)milk free for 48 hrs.; caffeine free

Discharge planning: teach parents S&S of dehydration

DIVERTICULITISDefinition/Pathophysiology: -a saclike outpouching of the lining of the bowel

(If bowel contents are retained in the sac, it becomes inflamed or infected)

Assessment: -chronic constipation-abdominal pain (especially LLQ)-fever-abdominal distention/tenderness

Diagnostics:- Ultrasonography-barium enema( not during acute phase)-increased ESR & WBC-decreased H&H-colonoscopy (after acute phase)

Complications:-possible peritonitis- abscess formation & bleeding

Treatment/ManagementDietary: -Severe stage: NPO, NGT, IV’s -During inflammation: low fiber clear liquids initially -After inflammation: high fiber -Avoid foods with seeds, nuts, alcohol -Rest

Medications-Broad spectrum antibiotics (Flagyl, Cipro)- Mild analgesics

- Anticholinergics (pro banthine)- Bulk forming laxatives (metamucil)

Surgical Managementperitonitis or abscess formations may require surgery - one stage: bowel resection - multistaged: bowel resected and temporary colostomy performed

Nursing Managementteach pt. about dietary modificationsteach pt. about the various medsteach pt. about ostomy care if needed

PARALYTIC ILEUSDefinition/Pathophysiology: paralysis of peristaltic movement due to effect of trauma or toxins on the nerves that regulate intestinal movement

Assessment-abdominal pain/distention: accumulation of gas/fluid above the obstruction-rigid abdomen: increased distention makes it rigid-vomiting: earliest sign of high obstruction; bile if lower obstruction- constipation-absent bowel sounds: no peristalsis with obstruction-shock: loss of fluid/lytes from the bloodstream into intestines

IRRITABLE BOWEL SYNDROMEDefinition: functional disorder of intestinal mobility with no irritation (spasms)

Assessment: symptoms range from mild to severe in intensity with constipation, diarrhea or both - pain, cramps (LLQ) - bloating, abdominal distention -more females than males

Treatment/ManagementDietary modifications: ID food intolerances

limiting caffeine and avoiding alcohol -dietary fiber and bulk help stools

Medications -bulk forming laxatives (metamucil) -antidiarrheal agents (Lomotil) -anticholinergic agents (Bentyl) -tricyclic antidepressants (Elavil)-5-HT4 (Zelnorm)

Stress Management

Diagnostics: CT scan, possible endoscopy
