DYSFUNCTION
Chapter 25
Christine Limann Dyer, RN, MSN, CPN
GASTROINTESTINAL SYSTEM
Upper portion is responsible for nutrient intake
(ingestion)
Includes:
Mouth
Esophagus
Stomach
DIGESTION
Required to convert nutrients into usable energy
Performs excretory function and detoxification
Mechanical digestion
Chemical digestion
GASTROINTESTINAL SYSTEM
Lower portion is responsible for remainder of
digestion, absorption & metabolism
Includes:
Small intestine
Large intestine
Rectum
Anus
ABSORPTION
Principally from small intestine
Osmosis
Carrier-mediated diffusion
Active energy-driven transport (“pump”)
Large intestine
Absorption of water
Absorption of sodium
Role of colonic bacteria
GASTROINTESTINAL SYSTEM
Accessory Structures:
Liver
Gallbladder
Pancreas
INGESTION OF FOREIGN SUBSTANCES
Pica
Food picas
Nonfood picas
Foreign bodies
Nursing
considerations
DEVELOPMENTAL ASPECTS
(EACH DEVELOPMENTAL STAGE CONTRIBUTES TO THE
PROMOTION OF THE HEALTH OF THE CHILD)
Infant:
Prevent choking
Suck-swallow
Frequent feedings
Carefully introduce foods about 1 year of age
DEVELOPMENTAL ASPECTS
Toddler:
Weight gain (5-6 lbs/year)
Deceased caloric needs
Food “jags”
DEVELOPMENTAL ASPECTS
Preschooler:
Eats a full range of food
Appetite fluctuation
School-age:
GI tract stable (digestive system is adult sized)
Stools well formed
STRUCTURAL
GASTROINTESTINAL DISORDERS
UMBILICAL HERNIA
Signs & Symptoms:
Soft midline swelling
in the umbilical area
Complications:
Incarcerated
(strangulated)
Nursing Care:
Most resolve
spontaneously by 3-5
yrs of age
Surgery (pre-post
operative care)
Discharge instructions
ANORECTAL MALFORMATIONS
Signs & Symptoms:
Complications:
Rectal atresia (closure) and
stenosis (constriction or
narrowing of a passage)
Depends on the defect and
accompanying multisystem
involvement
Nursing Care:
Extensive treatment depending
on defect and associated organ
involvement
Preoperative care (caregiver
education & IV fluids)
Postoperative care (pain control,
s/s of infection, good skin care,
NG tube, oral feedings resumed)
Discharge instructions
OBSTRUCTIVE
GASTROINTESTINAL DISORDERS
HYPERTROPHIC PYLORIC STENOSIS
CONSTRICTION OF THE PYLORIC SPHINCTER WITH
OBSTRUCTION OF THE GASTRIC OUTLET
HYPERTROPHIC PYLORIC STENOSIS
Signs & Symptoms:
Typically: healthy, male infant: new onset non-bilious vomiting
progressing to projectile vomiting
Diagnosis:
Palpating the pyloric mass (olive-shaped)
Nursing Care:
Surgery (Ramstedt pyloromyotomy)
Assess dehydration, changes is VS, weight loss & discomfort
Preoperative care (NPO, NG tube,)
Postoperative care ( maintain fluids & electrolyte balance,
feedings, infection, keeping the wound clean & pain relief)
Discharge instructions (care of incision, s/s infection, response to
feedings)
INTUSSUSCEPTION
Telescoping or invagination of one portion of
intestine into another
Signs & Symptoms:
Acute abdominal pain, currant jelly stools, fever,
dehydration, abdominal distention, lethargy and
grunting due to pain
Diagnostic evaluation
Therapeutic management
Prognosis
Nursing considerations
ILEOCOLIC INTUSSUSCEPTION
MALROTATION AND VOLVULUS
Malrotation is due to abnormal
rotation around the superior
mesenteric artery during
embryonic development
Volvulus occurs when intestine
is twisted around itself and
compromises blood supply to
intestines
May cause intestinal
perforation, peritonitis,
necrosis, and death
Complications:
Shock (signs include; tachycardia,
tachypnea, hypotension & cool,
clammy or cyanotic skin)
INFLAMMATORY DISORDERS
IRRITABLE BOWEL SYNDROME (IBS)
Identified as cause of
recurrent abdominal
pain in children
Classified as a
functional GI disorder
Alternating diarrhea
and constipation
Therapeutic
management
Nursing
considerations
INFLAMMATORY BOWEL DISEASE (IBD)
Two types
Crohn’s Disese
Ulcerative Colitis
ULCERATIVE COLITIS (UC)
Pathophysiology –inflamation in colon and
rectum
Clinical manifestations – ulceration, bleeding,
anorexia, anemia
CROHN’S DISEASE
Pathophysiology-Crohn's disease is an
inflammatory bowel disease (IBD)
Clinical manifestations-abdominal pain, severe
diarrhea and even malnutrition
Extraintestinal manifestations-arthritis, skin
problems, fever, anemia
Therapeutic management
Medical- corticosteriods,
Remicade for remission, 6-MP
Surgical
Nursing considerations – nutritional support,
education
APPENDICITIS
Signs & Symptoms:
Earliest symptom; periumbilical
pain, vomiting
Followed by: right lower quadrant
pain (classic sign)
Clinical Alert:
Children who respond yes to being
hungry most likely do not have
appendicitis
Nursing Care:
Surgery
Postoperative care (monitor intake
& output, wound care, pain control,
NPO until peristalsis returns,
discharged home in 2-3 days)
If perforate appendix intravenous
antibiotics are given, NPO with NG
tube until bowel function returns
OMPHALITIS
Signs
& Symptoms:
Redness & edema of the
soft tissue
Diagnosis:
Culture obtained to
confirm diagnosis
Nursing
Care:
Prevention by good
perinatal care & caregiver
education
Intravenous broadspectrum antibiotics
MECKEL DIVERTICULUM
Most common congenital
malformation of the GI tract
Band connecting small intestine to
umbilicus
Signs & Symptoms:
Abdominal pain, painless rectal
bleeding, stools (bright or dark
red with mucus)
Complications:
If undetected severe anemia &
shock can occur
Nursing Care:
Surgical removal of the
diverticulum or pouch
Postoperative antibiotics
Correct fluid & electrolyte
imbalances
Monitor for shock & blood loss
Provide rest
Fluid replacement & NG tube
FUNCTIONAL
GASTROINTESTINAL CONDITIONS
INFANTILE COLIC
Signs & Symptoms:
Persistent, unexplained crying –
younger than 3 months
Episodes occur at the same time
each day
Diagnosis:
Based on symptoms occurring for
more than 3 weeks, for 3 days (2-3
hours a day)
Nursing Care:
Rule out acute conditions
Management strategies (see Box
25-1)
ACUTE DIARRHEA
Signs & Symptoms:
Increased frequency & fluid content of the stools with or without
associated symptoms
Additional Symptoms:
Caregiver asked about vomiting, fever, pain, number of wet
diapers in previous 24-hours)
Nursing Care:
Hydration & dietary needs
Pharmacology treatment not ordered
IV fluids essential with impaired circulation and possible shock
CHRONIC DIARRHEA
Signs & Symptoms:
Reflective of underlying pathology
History of the diarrhea; frequency & appearance
Additional Symptoms:
Abdominal distention or tenderness, hyperactive bowel sounds,
dehydration & condition of the perineal area
Nursing Care:
Treat the underlying cause
Enteral or TPN is provided for the child who is unable to
maintain adequate oral intake
Caregiver educated on prevention
VOMITING
Signs & Symptoms:
Assessment includes description of onset, duration quality, quantity,
appearance, presence of undigested food and precipitating event
Additional Symptoms:
Fever, diarrhea, ear pain, headache
Nursing Care:
Treatment of the cause & prevent of complications
Bowel is allowed to rest
Rehydration
Bland solids reintroduced
Antiemetic drugs
Dehydration, monitor fluid intake & output
Oral hygiene
CYCLIC VOMITING SYNDROME
Signs & Symptoms:
Recurrent episodic vomiting, usually lasts 24-48 hours.
Vomiting occurs at regular intervals, usually every two to
four weeks
Diagnosis:
Rule out other conditions
Nursing Care:
Supportive care: fluid replacement, rest, pharmacotherapy
& psychiatric evaluation
Calm stress-free environment
CONSTIPATION
An alteration in the
frequency, consistency, or
ease of passage of stool
May be secondary to other
disorders
Idiopathic (functional)
constipation—no known
cause
Chronic constipation—may
be due to environmental or
psychosocial factors
NEWBORN PERIOD
First meconium should be passed within 24 to 36
hours of life; if not assess for:
Hirschsprung disease, hypothyroidism
Meconium plug, meconium ileus (CF)
INFANCY
Often related to diet
Constipation in exclusively breastfed infant
almost unknown
Infrequent stool may occur because of minimal
residue from digested breast milk
Formula-fed infants may develop constipation
Interventions
- adding cereals, fruits and vegetables may help
(after 4 months)
CONSTIPATION IN CHILDHOOD
Often due to environmental changes or control
over body functions
Encopresis: inappropriate passage of feces, often
with soiling
May result from stress
Management
NURSING CONSIDERATIONS
History of bowel patterns, medications, diet
Educate parents and child
Dietary modifications (age appropriate)
Case Study
2 week old Joey is brought into the clinic by his mom because he hasn’t had
a bowel movement in two days. He is not eating and has abdominal
distention. She states that he didn’t pass meconium until the day after his
birth.
1. Describe the structural anomaly associated with Hirshbrung’s disease.
2. How is Hirshbrung’s diagnosed?
3. List 2 actual NANDA and 1 risk
4. If Joey is diagnosed with Hirsbrung’s Disease, what is the likely surgical
intervention?
5. What are possible complications for an older child?
HIRSCHSPRUNG DISEASE
Also called congenital
aganglionic megacolon
Mechanical
obstruction from
inadequate motility of
intestine
Incidence: 1 in 5000
live births; more
common in males and
in Down syndrome
Absence of ganglion
cells in colon
HIRSCHSPRUNG DISEASE
Signs & Symptoms:
Failure to pass meconium within the first 48 hours of life, failure to
thrive, poor feeding, chronic constipation, & Down syndrome
Complications:
Entercolitis is the most ominous presentation (abrupt onset o foul
smelling diarrhea, abdominal distention & fever. Rapid progress may
indicate perforation & sepsis
Nursing Care:
Surgical resection (colostomy)
Preoperative care (fluid & electrolyte status, NPO, NG tube, IV
fluids)
Postoperative care (maintain NG tube, monitor for abdominal
distension, assess for bowel sounds)
Teach caregiver how to car for colostomy, s/s of complications)
CLINICAL MANIFESTATIONS
OF HIRSCHPRUNG DISEASE
Aganglionic segment
usually includes the
rectum and proximal
colon
Accumulation of stool
with distention
Failure of internal
anal sphincter to relax
Enterocolitis may
occur
DIAGNOSTIC EVALUATION
X-ray, barium enema
Anorectal manometric exam
Confirm diagnosis with rectal biopsy
THERAPEUTIC MANAGEMENT

Preoperative care
Postoperative care
Discharge care
Temporary ostomy
Second stage “pull-through” procedure
GASTROESOPHAGEAL REFLUX (GER)
Defined as transfer of gastric contents into the
esophagus
Occurs in everyone
Frequency and persistency may make it
abnormal
May occur without GERD
GERD may occur without regurgitation
GER

history/physical &
decrease in symptoms
with elimination of
lactose from the diet
Nursing Care:
Elimination of dairy
products or the use of
enzyme replacement

Nursing considerations
SHORT BOWEL SYNDROME (SBS)
A malabsorptive disorder
Results from decreased
mucosal surface area, usually
as result of small bowel
resection
Etiology and pathophysiology
Result of decreased mucosal
surface area, usually due to
extensive resection of small
intestine
Other causes
NEC, volvulus, gastroschisis,
Crohn disease in
THERAPEUTIC MANAGEMENT OF SBS

to thrive, pruritus, hepatomegaly, splenomegaly
Diagnosis:
Early diagnosis in the key to survival.
Nursing Care:
Primarily supportive & focuses on providing nutritional support
Surgical resection: correct obstruction & provide drainage of bile from the liver into
the intestines

HEPATITIS
Signs & Symptoms :
Headache, anorexia, malaise, abdominal pain, nausea & vomiting
Diagnosis:
Based on history of exposure, symptoms & serologic testing
Nursing Care:
Primarily supportive: no specific treatment
Provide rest to the liver, hydration, maintain comfort, adequate
nutrition, & prevent complications
Immune globulin given to children who have been exposed to a person
with HAV
Vaccine available for HAV, HBV & HDV
Educate family regarding prevention measures (see Critical Nursing
Actions Prevention of Hepatitis A and Hepatitis B)
ABDOMINAL TRAUMA: INJURIES
Injuries
are the leading cause of death in
children
Ten percent of serious trauma occurs as a
result of abdominal & genitourinary injury
See Table 25-5 Injuries Caused by Abdominal
Trauma
DEHYDRATION
Types of dehydration
Diagnostic evaluation
Therapeutic management
Nursing considerations
1st treatment- Oral hydration Solution-OHS
DAILY MAINTENANCE FLUID
REQUIREMENTS
Calculate child’s weight in kg
Allow 100 ml/kg for first 10 kg body weight
Allow 50 ml/kg for second 10 kg body weight
Allow 20 ml/kg for remaining body weight
EXAMPLE 1:
DAILY FLUID CALCULATION
Child weighs 32 kg
100 x 10 for first 10 kg of body weight = 1000
50 x 10 for second 10 kg of body weight = 500
20 x 12 for remaining body weight = 240
1000 + 500 + 240 = 1740 ml/24 hr
EXAMPLE 2:
DAILY FLUID CALCULATION
Child weighs 8.5 kg
100 x 8.5 for first 10 kg of body weight = 850
No further calculations
850 ml/24 hr
EXAMPLE 3:
DAILY FLUID CALCULATION
Child weighs 14 kg
100 x 10 for first 10 kg of body weight = 1000
50 x 4 for second 10 kg of body weight = 200
No further calculations
1000 + 200 = 1200 ml/24 hr
