Specific Objectives:
By the end of this lecture, the student should be ableto:
Identify the surgery related differences between
adult and young children.
Discuss etiology, assessment criteria and therapeutic
management of gastrointestinal, respiratory,
skeletal and orthopedic anomalies.
Use the nursing diagnosis to develop nursing careplans for children with gastrointestinal, respiratory,
skeletal and orthopedic anomalies

Surgery Related Differences between Young
Children and Adults
The metabolic rate of the infant and
young children is much greater
proportionately than that of adult.
The body tissues of the child heal
quickly because of his rapid rate of
metabolism and growth.
-

The child usually needs proportionately less
analgesic than adult patient to obtain relative
comfort after surgical procedures.
The child lacks the reserve physical resources
that are available to the adult. His general
condition may change very rapidly , almost
without warning.
Abnormal fluid loss is more serious in the infant
and young child than in the adult. Fluid intake
and output must be calculated very carefully.

Some newborns with birthdefects are critically ill.They may need to betransported to medical
centers or specializedpediatric hospitals.
General Aspects of
Pre & Post-Operative Pediatric Care

Thus if acutely ill infant is to be transferred,
provision should be made to ensurethat the trip will be safe and thatthere will be no appreciable
deterioration of the infants condition

Safe means of transportation with aheated portable incubator andavailable oxygen supply is needed so asto maintain the infants bodytemperature and O2 therapies in theblood.
Equipment for suctioning to removesecretions is needed (as in esophagealatresia).
-

A nurse should participate in the
transfer of the baby to observe himduring that time and give appropriatecare in emergency (e.g. preventtorsion of an omphalocele, proper
position of infant).
All pertinent infant informationshould accompany the infant as hegoes from one health agency toanother

Psychological preparation of the child(according to his age). This aimed toprevention of fears common to children likefear of separations, fear of death.
The nurse should explain to the child andhis families what is going to occur.
Except in emergency situations, childrenshould preferably be free of respiratorycomplications and signs of malnutrition.

Most children must have nothing by mouthbefore surgery but the length of the time
the child remains NPO will depend on age(for newborns and infants 3-4 hours isusually enough).
The incision over or the part involved in
surgery must be washed and inspected.Shaving may be needed.The mouth should be checked for loose
teeth or for dentures (particularly in
children of 6-8 years of age). Any loose ormissing teeth should be charted in thechilds record.
-

Remove barrettes and pins from the childs
hair.Clothing should be warm and loose. The
child should be dressed in a hospital gownand under pants only.
Check the childs identification band to seethat is legible and secure. If not it needs tobe replaced prior to surgery.
Pre-medication: sedatives and analgesicsare usually given two hours before surgeryexcept in emergency situation.

The nurse should chart whether the child
has passed urine and had a bowel movement.Enemas are never done routinely but may beordered in some conditions.
Prior to taking the child to surgery,
especially in newborns and infants, nostrilsshould be carefully cleansed (hard crustsmay be softened with a solution of sodiumbicarbonate, normal saline, or even warm
water). This is necessary to because crustsmay be obstructing the airway.

The child may need to take his favoritetoy with him to surgery. Ideally, heshould be allowed to keep the toy withhim until he is under the anesthetic.
Parents should be allowed to
accompany their children to theoperation site if they so desire.
Parents should be told where to wait
during the surgery, whether the child willgo to recovery room after surgery ordirectory to his unit.

After return from the operating room, thechilds general condition must be closely
observed
Vital signs, especially temperature.
Airway must be kept patent newbornbabies must be kept in warm cot orincubator.

Unit the child is responsive andalert; he should be kept on his side
(for secretion and vomitus to getout from mouth).
Observe conditions and placementof dressing. Check and mark anyapparent drainage from wound.
Intravenous fluids should bechecked for correct rate of flowand for possible infiltration.
-
8/3/2019 Congenital Anomaly 2011 2012

The child should be carefully handled andshould be protected from harming himself by
use of appropriate restraints.Any urinary catheter should be connected to
drainage bag and stabilized properly to bed.
Observe patients skin color and temperatureas well as any sings of shock :
(a) low blood pressure
(b) rapid pulse
(c) cold moist pale or cyanotic skin
(d) dilated pupils
(e) restlessness.

Oral fluids may be started often after thefollowing criteria are observed (a) color ofaspirate is clear (b) peristaltic movements
are heard (c) flatus or gases are passed. Oral fluids should be started while infusion
still on. If well tolerated then infusion isgradually discontinued.
Routine postoperative diet is modifiedaccording to childs age, but in general itchanges from clear of liquid, full liquid, softand then regular diet.
Sedatives are used according to prescribedorders and childs needs.

For children who can walk, early progressiveambulation is the rule (expect in few cases),
this will help to restore GIT function andprevent complications of pneumonia, thethrombosis, and pressure areas.
If too young to go out of bed, the nurseshould turn the child frequently and give himgood skin care and help him to breath deeplyat intervals.

Anomalies of the Mouth
It is a congenital fissure in the upper lip. It is
generally located at one side or the other of
the midline in the center of the nares. It maybe unilateral or bilateral

It is incomplete fusion of the palatal shelves.The opening may involve only the soft palate
or the hard palate or both.
It may be a single midline cleft or twobilateral clefts.Cleft palate may occur in connection with
cleft lipCause:Both cleft lip and palate result from failure of
or incomplete union of embryonic structuresof the face.

Feeding baby with cleft palate
Breast-feeding is allowed. It will take extra timeand patience.
Hold an infant in an upright position to help
keep the food from coming out of the nose. Small, frequent feedings are recommended.
There are many types of bottles and nipples that
can assist with feeding an infant with cleftpalate.

Post-operative Care:
Place infant/ child in humidified air andwarm him.
Maintain I. V. fluids.
Suctioning whenever needed, if he can notswallow saliva.
Observe respiration, report immediately ifthere is respiratory difficulties are presentor atelectasis.
If there is gastrostomy tube feeding it
-
8/3/2019 Congenital Anomaly 2011 2012
51/133
If there is gastrostomy tube feeding, itmust not be elevated more than 4 inches(10 cm) above stomach level to preventreflux to healed esophagus.
Use pacifier to satisfy infants need for
sucking.
Start oral feeding gradually whenesophagus anastomosis has healed, butcontinue gastrostomy feeding until theinfant takes adequate amount per mouth.
Teach parent before infants discharge
how to care for him at home.

Is hypertrophy of the muscle surrounding the
pylorus that leads to narrowing of the pyloric
canal and makes it difficult for the stomach to
empty. It occurs mainly in male infants.

It occurs when there ishypertrophy of thecircular muscle of thepylorus leads toconstriction of thepyloric canal andobstruction of the gastricoutlet
-
8/3/2019 Congenital Anomaly 2011 2012
58/133
The circular muscle of the pylorus isgrossly enlarged as a result of bothhypertrophy (increased size) andhyperplasia (increased mass).
-
8/3/2019 Congenital Anomaly 2011 2012
59/133
This produces severe narrowing ofthe pyloric canal between the
stomach and the duodenum.Consequently, the lumen at thispoint is partially obstructed over aperiod of time, inflammation andedema further reduce the size ofthe opening until the partialobstruction may progress to
complete obstruction.

In neonate: diagnosis is usually based onclinical signs of intestinal obstruction and
failure to pass meconium. On examination, the rectum is empty of
feces, the internal sphincter is tight andleakage of liquid stool.
Barium enema and rectal biopsy. Non-invasive procedure may be used asanorectal manometry.

Intussusception is one of the mostfrequent causes of intestinal obstructions
in children between the ages of 3months and 5 years.
Half of the cases occur in children
younger than 1 year, and most of theothers occur in children during the secondyear.
-
8/3/2019 Congenital Anomaly 2011 2012
92/133
Exact cause of Intussusception is uncertain but there areseveral theories as:
Greater disparity between the size of the ileum andileocecal value in infants is believed to encouragetelescoping at this point.
Distorted peristalsis due to change of diet (weaning).
Enlarged lymph nodes along the G.I.T. that occur withrespiratory infections, cystic fibrosis, foreign bodies, G.Ipolyps.
Hyperperistalsis.Diarrhea, constipation.
Mobile ileocecal junction.

Therapeutic Management:
The initial treatment of choice is non-surgical hydrostatic reduction.
Traditionally by barium enema:
In this procedure, correction of theinvagination is carried out at the sametime as the diagnostic testing.
The force exerted by the flowing barium isusually sufficient to push the invaginatedportion of the bowel into its originalposition.

For cases of gastrochisis, omphalocele, umbilical andinguinal hernias.
Do not apply pressure on herniated area.
Nasogastric suctioning for omphalocele / gastrochisis.
Apply sterile dressing over herniated area foromphalocele/ gastrochisis.
Keep the child quiet, no crying in particular in cases ofharnias, especially umbilical hernia. Give warm bath,suck pacifier to calm the infant.
Educate parent about strape the defect has no valueto decrease hernia.
