Q

Nursing Management of CL/CP: Pre-op feeding

A
  • cleft lip/palate reduces ability to suck
  • some CL babies may breastfeed
  • mother’s breast soft, fill gap caused by cleft
  • CP makes it difficult to create suction
  • food enters nasal cavity through cleft (OM, fluid accumulation)
  • bottle feed with expressed breast milk
  • hold head in upright position

Pyloric Stenosis
- hypertrophic obstruction of the circular muscle of the pyloric canal - occurs in 1-3 per 1000 live births, may be familial - male to female ratio 6:1 - seen more frequently in firstborn white males
26
Pathophysiology for Pyloric stenosis
- pylorus sphincter narrows due to progressive hypertrophy of the circular pylorus muscle - results in outlet obstruction
27
Clinical Manifestations of Pyloric Stenosis
- 2-6 weeks after birth - initially infant appears well or regurgitates after feeding - vomiting progresses to projectile - vomiting is non-bilious (no bile in vomit), may be blood tinged - infant: hungry, irritable, fail to gain weight, fewer and smaller stools - if goes on too long: dehydration, metabolic alkalosis and increased bilirubin
28
Clinical therapy: Diagnosis of Pyloric Stenosis
- physical exam: visible peristaltic wave across the abdomen moving from left or right - olive-size mass in left upper quadrant - pyloric ultrasound - upper GI series
29
Clinical therapy: Treatment of Pyloric Stenosis
- surgery: pyloromyotomy - release of muscle fibers allows the passage of food and fluid - high success rate
30
Nursing Management: Pre-op of Pyloromyotomy
- NPO - IVF - Monitor electrolytes - NGT for decompressing
31
Nursing Management: Post-op Pyloromyotomy
- pain management - vital signs monitoring - establish feeding - involve parents - discharge teaching
32
GASTROESPHAGEAL Reflux (GER)
- return of gastric contents into the esophagus due to relaxation of the lower esophageal or cardiac sphincter - 50% of FT infants have GER - higher in premature infants - males affected 3x more than females - children with neuro impairment (CP) have increased GER - peak age is 1-4 months of age, often resolves spontaneously by age 12 months
33
GERD
- more serious than GER - spit up any time, even between feedings - cries and arches back during and after feeds - eat often but still lose weight - respiratory problems: cough, wheeze, choking, color changes during feeding (ALTE?) - may aspirate: pneumonia, apnea - generalized irritability, poor weight gain, weight loss or delayed growth
34
Diagnosis of GERD
- hx of feeding, vomiting episodes, pain with feeding - upper GI series: UGI: check for anatomic abnormalities - pH probe monitoring: valid and reliable measure of reflux, determines number of reflux episodes
35
Treatment of GERD
- depends on severity - mild: "happy spitter" - modification of feeding habits: small frequent feeds, frequent burping - thicken formula with rice cereal (1 tsp RC/ 1 oz formula) make nipple hole bigger - position: hold child upright after feeds for 20-30 min - supine position while sleeping due to risk of SIDS (AAP)
36
Pharmacological Tx for GERD
- moderate to severe - poor weight gain, irritable, no improvement with modification of feeding habits and position - H2 Receptor Antagonists - Proton Pump Inhibitors
37
H2 Receptor Antagonists
Action: decrease gastric acid production "silent reflux" reflux without vomiting Ranitidine (Zantac) Fomatidine (Pepcid)
38
Proton Pump Inhibitors
Action: blocks acid production by inhibiting proton pumps, increases LES tone, more effective than H2 receptor agonists - works better than H2 - risks of aspiration patients - insurance issues (ranitidine first) Lansoprazole (Prevacid) Omeprazole (Prilosec)
39
Severe GERD
- failure to thrive, aspiration - surgical management: Nissen Fundoplication - Gastrostomy tube is inserted during surgery and left in place for 6 weeks or longer
40
Nissen Fundoplcation
involves a 360 degree wrap of the fundus of the stomach around the distal esophagus -acts like a sphincter
41
In children with GERD
- observe for respiratory distress, monitor VS - provide adequate nutrition, small frequent feeds - position, increase HOB, prone position with caution while awake only
42
Post-op Fundoplication
- GT: maintain integrity, secure tube, provide pacifier | - educate parent about home care: feeding, position, medication, suctioning
43
Hirschsprung Disease
- congenital aganglionic megacolon - decreased motility causes obstruction of the intestines - incidence: 1:5000, males more than females - familial tendency - can occur with Down syndrome, congenital heart disease, other syndromes
44
Pathophysiology of Hirschsprung
- absence of ganglion cells in one segment of the colon causes lack on innervation in that segment - usually rectosigmoid colon - prevents peristalsis: leads to blockage, and stool builds up behind blockage - results in constipation, abdominal distension, poor weight gain, poor growth
45
Clinical Manifestations of Hirschsprung Disease in Newborn
- lack of meconium stool - bilious vomiting - S/S enterocolitis
46
Clinical Manifestations of Hirschsprung Disease in Older Child
chronic constipation alternating with diarrhea, ribbon-like stools, abdominal distension, poor weight gain, decreased growth
47
Diagnosis of Hirschsprung Disease
- barium enema, abdominal xray, dilated bowel - rectal examination: rectum small, no stool - anal manometry - (gold standard) rectal biopsy: absence of ganglionic cells CONFIRMS DIAGNOSIS
48
Treatment child with milder defect (Hirschsprung)
- dietary modification: high fiber diet - stool softeners - enemas to prevent impaction in children not toilet trained
49
Treatment of infant with Hirschsprung
- surgical removal of the aganglionic bowel and pull through procedure - temp colostomy: closure 2-6 months later - normal bowel function depends on the amount of bowel involved
50
Enterocolitis
inflammation of small intestine and colon - results in ischemia and ulceration of the bowel wall - may occur before or after surgery - greatest cause of morbidity and mortality in Hirschsprungs
51
Enterocolitis presents with...
-abdominal pain, fever, foul smelling and/or bloody stools
52
When should enterocolitis be suspected in neonate...
- distended abdomen - feeding intolerance with bilious vomiting - delay of meconium
53
If enterocolitis is not recognized...
- progress to sepsis - perforation Tx: IVF, antibiotics, NGT, monitor electrolytes and VS
54
Nursing Management Pre-op of Enterocolitis
- dependent on condition - assess: skin turgor, fontanels, urinary output, MMs - monitor fluid and electrolyte balance - maintain nutrition, TPN if NPO - ensure patent NG tube if NPO - monitor abdominal circumference - encourage parent to hold and cuddle infant
55
Nursing Management Post-op of Enterocolities
-PO clear or breast milk in several hours * Observe for signs of enterocolitis * Monitor I/O * Avoid pressure on incision – diapering * Provide comfort, pain relief * Encourage parents to partake in infant’s care * Discharged when tolerating full feeds
56
Intussusception
- occurs when one portion of the intestine invaginates or telescopes into another - one of the most frequent causes of intestinal obstruction in children - more common in males - peak age: 3-9 months, up to 3 yrs
57
cause of intussusception
unknown, viral infections, intestinal polyps, medications, Rotashield vaccine
58
Pathophysiology of Intussusception
- most common site is the ileocecal valve - telescoping of the intestines obstructs the passage of stools - intestinal walls rub together causing inflammation, edema, and decreased blood flow - leads to necrosis, perforation, hemorrhage, peritonitis
59
Clinical Manifestations of Intussusception
- sudden onset of abdominal pain, draw legs to chest - may vomit - periods of calm between episodes of pain - abdominal pain and distension - palpable "sausage-shaped mass" in upper right quadrant - passage of "currant-jelly stools" (blood and mucus stool)
60
Diagnosis of intussusception
- made on subjective findings, history - abdominal xray - abdominal US CONFIRMS DIAGNOSIS
61
Treatment of Intussusception
- may spontaneously reduce without treatment - hydrostatic reduction by air, saline, or barium enema - rare: surgery to reduce or to remove necrotic bowel - NG tube for gastric decompression
62
Nursing Management Pre-op: Intussusception
- maintain IVF - fluid and electrolye balance - NGT decompression - antibiotic therapy
63
Nursing Management Post-op: Intussusception
- monitor for infection - pain management - NGT patency - assess VS - check for abdominal distension - bowel sounds
64
When to discharge from Intussusception surgery
- when tolerating feeds | - D/C teaching: can reoccur after enema or surgery, must return for fever, pain, bloody stools
65
If infant is NPO...
offer pacifier to continue sucking reflex -can lead to difficulty eating and develop food aversions
66
Newborn BMs
1-10 BMs a day
67
NB NB vomit
non-bilious and non-bloody vomit
68
