Gastrointestinal System - Pedi Flashcards
GASTROINTESTINAL SYSTEM
*Route to ingest, digest, and absorb foods, fluids, vitamins, and nutrients
*Excretion/elimination of solid waste
*GI tract:
*Mouth, esophagus, stomach, pancreas, small intestine, large intestine
*Helper organs:
*Liver, gallbladder, spleen
DIFFERENCES BW PEDI AND ADULT
*Mouth – infants/young children oral phase – risk for infectious agents
*Swallowing - involuntary until 6 weeks
*Esophagus – lower esophageal sphincter matures at 1mos – prior to this regurgitation common
*Stomach capacity – smaller
*2 mos – 200 mLs (most smaller amts)
*16yo – 1500mLs
*Adult – 2000 mLs – 3000 mLs
*Digestive enzymes – deficient until ~6 months
*Small intestine
*~250 cm at birth
*600 cm in adult
*Liver function
*bilirubin conjugation starts at 2-3 weeks of age
*Pancreatic enzymes at adult levels by 2yo
*Palpable at birth – relatively large
*Excretory function – control of defecation (awareness/control 18-24 months)
*Total Body Water: infants/children > adults
PEDIATRIC GI ASSESSMENT (Health History)
*Past history – birth history, hospitalizations
*Present illness – onset? Symptoms? Assoc symptoms?
*Growth and development – gaining/ growing
*Emesis – Spitting up vs vomit, when? Frequency? Color? Volume?
*Stool – color, consistency, passage of meconium, pattern – BF usually with every
feed, Bottle 1-2 per day, size, abdominal pain, leaking/staining
*Nutrition – intake, appetite
*Activity – more sleep? Changes in activity level? Mental status?
*Family hx: IBS? IBD? Food allergies?

STRUCTURAL ANOMALIES
(Cleft Lip and Palate)
Most common congenital craniofacial defect:
frontonasal and/or maxillary processes did not
fuse
*~1 in 700 births
*Unknown cause. Contributing factors:
*Genetics, folic acid deficiency, advanced
maternal age, anticonvulsants, ETOH &
smoking, family hx
*25-30% also have syndrome/other
abnormalities
*Lip tissues fuse 5 – 6 weeks gestation
*Palate closes 7-9weeks gestation
STRUCTURAL ANOMALIES:
Complications cleft lip and palate
- feeding difficulties
- insufficient growth
- altered dentition
- delayed or altered speech
- otitis media with effusion
STRUCTURAL ANOMALIES:
Treatment cleft lip and palate
Tx: Multidisciplinary team: plastic surgeon or
craniofacial specialist, oral surgeon, dentist or
orthodontist, psychologist, otolaryngologist, nurse,
LICSW, audiologist, and speech language pathologist
Surgical repair cleft lip and palate:
*Lip 2-3 months – early repair improves feeding and
appearance
*Palate 6-9 months – essential for speech
development
STRUCTURAL ANOMALIES:
Cleft Lip and Palate Nursing Management
- Promoting adequate nutrition – may need special nipple, burp frequently
- Aspiration risk – prior to repair for palate may have a prosthodontic device
- to act as palate / breastfeeding may be more effective due to the soft breast tissue that is pliable and may cover opening
- Post op some surgeons resume BF immediately / special nipples for bottle fed
STRUCTURAL ANOMALIES:
Cleft lip and palate, nursing management
*Parent – Infant bonding: appearance may affect
*Emotional support
*Post operatively:
*Feeding support, may need restraints to prevent rubbing / touching surgical site,
certain things in mouth may affect repair ie no pacifier, straws, suction catheters
*Avoid vigorous or sustained crying
STRUCTURAL ANOMALIES:
Esophageal Atresia
*proximal and distal ends of esophagus do not communicate
*upper esophagus ends in a pouch / lower portion ends above the
diaphragm
STRUCTURAL ANOMALIES:
Tracheoesophageal Fistula
- abnormal communication between esophagus and trachea
- BOTH Atresia and Fistula typically associated with other abnormalities:
- VACTERL work up
- Vertebral, Anal atresia, Esophagus, Trachea, Renal abnormalities, or limb differences
STRUCTURAL ANOMALIES:
Esophageal Atresia and Tracheoesophageal Fistula
*maternal hx of polyhydramnios
*neonate with copious, frothy bubbles in mouth and nose and drooling
*abdominal distension – air accumulates
*can not insert NGT
*newborn with rattling respirations, excess salivation
*3 C’s: cough, choking and cyanosis with feeding
STRUCTURAL ABNORMALITIES:
Nursing Management Atresia and Fistula
*Preop:
*NPO
*HOB elevated prevent reflux/aspiration
*Orogastric tube – low wall suction / avoid irrigation
*I+O’s – fluid and electrolyte
*Comfort measures avoid crying
*Postop:
*TPN
*Antibiotics
*PO /NGT feeds about a week postop
*No deep suctioning
STRUCTURAL ANOMALIES:
Omphalocele
*Congenital anomaly of anterior abdominal wall
*Defect of umbilical ring
*Vary in size
*Evisceration of abdominal contents into an external peritoneal sac
*Bowel / liver / entire GI tract
STRUCTURAL ANOMALIES:
Gastroschisis
- congenital defect of anterior abdominal wall
- Herniation of abdominal contents thru a defect, typically to left or right of umbilicus
- NO peritoneal sac protecting organs, exposure to amniotic fluid - thickened, edematous and inflamed
STRUCTURAL ANOMALIES:
Nursing Assessment Gastroschisis and Omphalocele
- size of deformity
- appearance of organs
- look for twisting of intestine
- Full exam looking for other deformities ie VACTERL
STRUCTURAL ANOMALIES:
Nursing Management Omphalocele/ Gastroschisis
- Prevent hypothermia
- Prevent fluid loss
- Prevent trauma to exposed contents
- Prevent infection – sterile technique/antibiotics
- NPO / orogastric tube / PN
- Monitor exposed contents for vascular changes
STRUCTURAL ANOMALIES:
Omphalocele/ Gastroschisis
(Treatment, Surgery, Post op)
Treatment:
Surgery: exact way repaired depends on size of defect/size of child/ stability of child
May due primary closure or staged closure
Possibly silo closure
Post op:
monitor closely for respiratory compromise
pain management
fluids
Initiation of feeds
STRUCTURAL ANOMALIES:
Anorectal Malformations
Anomalies Associated with:
* VACTERL syndrome
* Esophageal atresia
* Intestinal atresia
* Malrotation
* Renal agenesis
* Hypospadias
* Vesicoureteral reflux
* Bladder exstrophy
* Cardiac anomalies
* Skeletal anomalies
Anorectal Malformations
**Imperforate Anus
*** Rectum ends in a blind pouch
* Level of defect influences outcome – fecal continence
* Staged repair
* Colostomy while waiting repair
Nursing Assessment Imperforate Anus
- newborn assess for normal anal opening
- passage of meconium stool within 24hours of birth
- assess UO to identify accompanying GU abnormalities
- assess for signs of intestinal obstruction – distension/vomiting
Nursing Management: Imperforate Anus
- Preop: NPO, gastric decompression, hydration status, education
- Postop: pain, NPO maintained, gastric decompression, colostomy care, if needed.
- After intestinal pull thru initially stool will be watery – skin breakdown
STRUCTURAL ANOMALIES:
Meckel’s Diverticulum
Congenital – 3-6 cm outpouching (bulge) of lower segment of small intestine
*Most common birth defect of GI system – 2-3% population
*Most children asymptomatic
*If symptoms, usually age 1-2y
*Painless rectal bleeding
*“brick” or “currant jelly” – very red stool
Can be associated with partial or complete bowel obstruction
*Obstruction – younger children
*Diverticulitis - older children (~ 8y) - looks like appendicitis
Meckel’s Diverticulum:
Common Complications
- Anemia
- Bleeding
- Ulcer
- Obstruction (volvulus / intussusception)
- Typically occur in first 2 years of life
Presentation Meckel’s Diverticulum
- Rectal bleeding, painless
- Abdominal pain
- Bloody, mucusy stools
Meckel’s Diverticulum: Dx
- Meckels Scan (radionuclide scan), CBC and metabolic panel
