UNIT 5: GASTROINTESTINAL CONDITIONS ANORECTAL MALFORMATIONS Rectal atresia (Closure of the rectal passage) no stool. Initially, anus may appear to be normal in appearance, but it is later determined as an abnormal situation and is a complete obstruction that precludes the passage of stool. Immediate surgical intervention is mandatory for rectal atresia. Rectal stenosis (Constriction or narrowing of the rectal passage) includes vomiting, abdominal distension, difficulty passing stool. May present with a ribbon-like or narrow stool, which is not always apparent at birth. Imperforate anus (Absence of a rectal opening) no stool. Surgery is required. Failure to pass bowel in first 24 hrs after birth Can appear as a Rectal fistula - rectal connection to vagina or urethra through which stool passes. Surgery is required to close the fistula. The visualization of gas in the bladder or urethra during imaging also indicates the presence of a fistula connection between the bowel and associated structure. Passage of meconium through the vagina, urethra, or an opening under the scrotum is early evidence of an imperforate anus though the presence of a fistula may not be evident at birth. Child will be placed in prone position after surgery or side lying with knees flexed Diagnosis Physical examination Surgical Care: Radiological imaging (x-ray) Visualizing of gas in the bladder or o Repeated manual dilation to treat urethra during imaging also indicates anal stenosis the presence of a fistula connection o Creating a new anal opening for between the bowel and associated structure. rectal atresia – two stages Magnetic resonance imaging (MRI) of  First stage is resection the lumbosacral spinal cord is required and creation of a for all children presenting with an temporary colostomy. imperforate anus to rule out the presence of a tethered spinal cord Ultrasound (outlines the shape of tissues and organs of the abdomen and pelvis). IV pyelogram: (provides information about the structure and function of the   2nd stage involves the closure of the colostomy and anastomosing the blind pouch of the rectum to the anus. Nursing care: o Depends on type of defect and extent of surgical correction. o Child is kept NPO; therefore, the care of the infant before surgery includes parent education and maintenance of IV fluids. o Post-op – pain control and the importance of infection control post surgery for the incision site because of potential fecal or urinary contamination. Also, during post op, nurses monitor VS, I&O’s, fluid maintenance, pain control, and developmentally appropriate play. o Nurse communicates to the family that post op for high anorectal malformations a colostomy is placed and must do colostomy care. o Presence of a colostomy: good skin care & infection control in post operative. o Nasogastric decompression is often required early in post op period and ORAL FEEDINGS ARE GENERALLY INITIATED WITH THE REESTABLISHMENT OF PERISTALSIS AND ONCE STOOLING HAS BEGUN. Education Discharge Information: o Colostomy care, wound care, prevention of infection. o The procedure for anal dilation if appropriate for the defect-may need to do this multiple times. o Adequate fluids o Dietary fiber o Stool softeners or bulking agents o Parents are advised about the potential for delayed toilet training Hypertrophic Pyloric Stenosis Etiology is unknown. Thickening of the pyloric sphincter, causing an obstruction of the pyloric canal. Affects kids 3-6 weeks More common in Caucasian population.  More common in males-especially first born. May reveal an infant in metabolic alkalosis resulting from the loss of large amounts of of gastric hydrochloride acid. Diagnosis  Palpating pyloric mass (olive-shaped) best palpated from the left side and located above and to the right of the umbilicus in the midepigastrium (the superior central portion of the abdomen beneath the liver edge).  Ultrasound usually confirms the Pyloric Stenosis (shows elongation and thickening of the pylorus, which may be confirmed with barium.  An abdominal x-ray film may show an enlarged stomach with diminished or absent gas in the intestine  Confirmation by upper GI series demonstrates S/S: “string sign,” which is caused by barium o Pattern of normal feedings and passing through narrowed pylorus then new onset of non-bilious vomiting containing undigested food. o Projectile vomiting-may occur right after the feed. Then baby wants to eat again. The vomiting usually begins with episodes of regurgitation during the first few weeks of life. o Insatiable appetite o Olive shaped mass (RUQ) o Visible reverse peristalsis in LUQ o Hypochloric (low chloride) o Weight loss o Dehydration o Constipation Surgical Care o Pyloromyotomy (incision and suture of the pyloric sphincter)- laparoscopic procedure with endoscope. o The nurse communicates with the family that it is COMMON for the infant to experience some vomiting in the first 24-36 hours after surgery.  o Whether or not bowel sounds are present, feedings begin 6 hours after surgery. o "Pedialyte 15 mL is given every 2 hours for two consecutive feds, if the baby tolerates this with no vomiting, then His advanced to half- strength formula 15 mL every 2 hours for two consecutive feeds. If no vomiting, then advance to 30 mL for two consecutive feeds, then 45 mL for two consecutive feeds, and finally 60 mL for two consecutive feeds. o If baby were to vomit, then the baby stays at that level until two consecutive feeds are tolerated. Nursing care o The nurse needs to be alert for signs and symptoms of dehydration such as: changes in skin turgor appearance of the mucous membranes depressed fontanelle presence or absence of tears urine output changes in vital signs weight loss evidence of discomfort o Pre-op: Child is NPO, and a gastric tube is inserted to provide gastric decompression. o If dehydration is present before surgery IV fluids is administered of appropriate electrolyte therapy. o Post-op - Maintain IV fluids, monitor V/S frequently, I & O’s, pain mgmt, monitor for s/s of infection, keeping the wound clean and dry and changing diapers is the way to prevent infection of the wound. And providing pain relief. Education & Discharge Instructions o Care of incision and observation for signs of infection o Change diapers frequently o It is important after surgery to let the family know about the importance of saving wet diapers that are weighed to measure output.  o Observe infant’s response to feedings, as some vomiting may still occur within first 48 hours postoperatively o Vomiting beyond 48 hours must be reported to child’s health-care provider. o Tell parents to change diapers as soon as possible for children who are not toilet trained. Cleft Lip & Cleft Palate Birth defect characterized by incomplete formation of the lip (cleft lip) or the roof of the mouth (cleft palate) Maternal age higher than 35 years old American Indian or Alaska Natives Babies with Cleft Palate before surgical correction are more at risk for frequent episodes of acute otitis media due to the opening in their oropharynx. May have increased difficulty with forming a good seal and thus have a poor suck, increasing the risk for feeding difficulties. At risk for otitis media or chronic sinusitis S/S: o Unilateral or bilateral cleft lip o Can occur with or without a cleft of the hard and/or soft palate o Both or either of the palates can have cleft without lip affected o Uvula can also contain cleft Nursing Care o Initial focus is assessment of the infant’s airway and sucking ability. o Infants with a cleft palate cannot effectively suck from a bottle or breast and will require adaptive feeding equipment before surgery, such as a modified shorter nipple that expresses liquid into the mouth but not into the posterior pharynx. o Infants with cleft lip may require a longer nipple but may be able to feed independently from the bottle or breast. o Maintaining adequate nutrition o Breastfeeding possible but may be interrupted for period of time based on the need for surgical repair  o Bottle feeding is initiated with special nipple that is longer than a regular nipple to help prevent aspiration. Has a reservoir to regulate the flow of formula. (Haberman feeder) o Feed in upright position to decrease the incidence of regurgitation (not in infant seat) o After feeding rinse the mouth with water Surgical Care of Cheiloplasty o Surgical repair of Cleft lip is typically done at or before 3 months of age o Surgical repair of Cleft palates is usually repaired before 6-18 months but should be performed before the child begins speaking. o Some repairs may require more than one surgical procedure. Surgical Care of a Cleft Lip o Z-plasty to minimize retraction of scar o Protect suture line with Logan bow or other methods o No-No’s sleeves (keeps elbows locked out to prevent infant from touching the face Education/Discharge Instructions: Educate parents that the things shown below can decrease pregnancy risk for developing cleft lip and palate: o Avoid certain medications such as medicines used to treat seizures, and methotrexate, which is used to treat cancer and other diseases. o Avoiding cigarettes and alcohol. o Taking prenatal multivitamins that contain at least 400 micrograms of folic acid. o Telling the health care provider about the prescription drugs, over the counter medications and supplements. o Cleft palate-position in upright position. Use bottle with one-way flow valve o Cleft lip-Use nipple with wide base, squeeze cheeks together during feeding o Apply petroleum jelly to operative site as directed o Feeding with a syringe or dropper o Avoid use of pacifiers o Nothing in mouth after surgery  A, Haberman feeder. B, Mead-Johnson bottle used to feed infant with cleft lip and palate. C, Pigeon bottle Intussusception Intussusception occurs when one portion of the intestine invaginates or telescopes into another portion, most commonly at the ileocecal valve. It is a condition in which a proximal segment of the bowel prolapses into a distal segment of the bowel. Small intestine goes into the large intestine Most common in 6-36 months of age. Classic symptomatic triad signs: 1. Paroxysmal abdominal pain with vomiting every 5-30 min (pain that comes and goes) 2. screaming and drawing up legs with periods of calm, sleeping, or lethargy between episodes 3. stool with blood (currant-jelly stool or mucous in stool). S/S: o Acute abdominal pain caused by the spasm if the telescoping bowel. Diagnosis o Pain mimics “colicky” infants Based on history of characteristic symptoms and o Infants may pull their legs up to abdomen physical findings during and inconsolable crying. examination o “Currant-jelly” stools – mucous mixed Presence of sausage-shaped mass palpable in RUQ (Dance’s with blood, stool-- possibly diarrheal sign) in nature with blood. Barium enema is gold standard o Fever, vomiting may follow episodes of for intussusception. Air enema is also therapeutic. abdominal pain, weight loss Abdominal ultrasound confirms the diagnosis in most cases  o Dehydration, lethargy, abdominal distention and grunting noises because of pain. Collaborative Care Nursing care for surgery: o Pre-op-: place an NG tube in child, child is placed on NPO, and initiating IV therapy. o Post-op-infection, hydration, pain management o Watch for signs of perforation, (peritonitis inflammation of the abdominal cavity), shock if evidence of increased pain, monitor vital signs o Monitor for the passage of normal, brown stool, which indicates a resolution of the obstruction. o If patient stools before surgery, call MD. Education/Discharge Instructions: o Care of incision o Observation for signs of infection o Teach feeding, dehydration and pain management Failure to Thrive (FTT) Not a diagnosis, but a description of a Identified criteria that is used to determine FTT condition that usually occurs in infancy Weight for length less than 10% and is characterized by failure of the Weight for age and sex less than 5% infant to achieve age-appropriate Length for chronological age and sex less than 5% weight gain Body mass index for chronological age less Child cannot take in enough nutrition than 5% to adequately meet standard growth Developmental delays, withdrawn and weight expectations. behavior Labs will show decrease prealbumin If child drops in weight reweigh them!!! Appendicitis CANNOT BE PROVENTED  IF PAIN STOPS NOTIFY DOCTOR IT COULD MEAN APPENDIX HAS RUPTURED!!! Inflammation of the appendix, which is a small sac-like structure at the end of the cecum. It is the most common abdominal surgical condition in children ages 6-10 years old. In appendicitis, the lumen of the appendix becomes obstructed with fecal matter, lymphoid tissue, tumor, parasite, foreign body, or inspissated- thickened cystic fibrosis secretions, which cause the appendix to become distended and subject to ischemia and necrosis. The characteristic symptoms are caused by the inflammation around the infected with approximately a 36–72-hour maximum window from onset of pain to the rupture of a gangrenous appendix.

Stool loss is considered excessive if it is more than 10g/kg in children less than 2. Stooling is 4 or more times in 24 hours in children older than 2 Multiple causes –Infections, Diet, Medications, or toxic materials Osmotic diarrhea occurs when water is pulled into the bowel due to conditions such as lactose intolerance, overfeeding Secretory diarrhea occurs when there is an increase in the active secretions of fluid or electrolytes into the stool.
