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.
8/7/2019 congenital anomaly2011
7/129
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.

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).
8/7/2019 congenital anomaly2011

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 information shouldaccompany the infant as he goes fromone health agency to another
8/7/2019 congenital anomaly2011

Pre-operativecare
8/7/2019 congenital anomaly2011

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.
8/7/2019 congenital anomaly2011
15/129
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.
8/7/2019 congenital anomaly2011
16/129
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.
8/7/2019 congenital anomaly2011

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
a) Vital signs, especially temperature.
b) Airway must be kept patent newbornbabies must be kept in warm cot orincubator.
8/7/2019 congenital anomaly2011
21/129
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.
8/7/2019 congenital anomaly2011
22/129
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.

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.

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.

Congenital diaphragmatic hernia
(CDH) is a malformation
characterized by a defect in the
Posterolateral diaphragm,
through which the abdominal
viscera migrate into the chest
during fetal life.
8/7/2019 congenital anomaly2011
52/129
Most common type due to early reduction of
physiological hernia (normal at the 10th week)
before closure of the foramen of Bochdalek by
the pleuroperitoneal membrane at the 8th
week.
It is more common on the Lt. Side because the
left side usually closes later than the Rt. Side
does. The sac is absent in 90% of cases.

It occurs when there ishypertrophy of the circular muscle ofthe pylorus leads to constriction of the
pyloric canal and obstruction of thegastric outlet
P th h i l
8/7/2019 congenital anomaly2011
69/129
Pathophysiology:
The circular muscle of the pylorus is grossly enlargedas a result of both hypertrophy (increased size) andhyperplasia (increased mass).
This produces severe narrowing of the pyloric canalbetween the stomach and the duodenum.
Consequently, the lumen at this point is partiallyobstructed over a period of time, inflammation andedema further reduce the size of the opening untilthe partial obstruction may progress to completeobstruction.

In the newborn:
The primary signs and symptoms are:
Failure to pass meconium within 24 48hrs after birth.
Food refusal.
Vomiting.
Abdominal distention.
During infancy:
8/7/2019 congenital anomaly2011
77/129
Inadequate weight gain. Constipation.
Abdominal distention.
Explosive watery diarrhea. Episodes of diarrhea and vomiting.
Bloody diarrhea, fever and severe lethargyare ominous signs because they signify the
presence of enterocolitis
During childhood:

Constipation. Passage of ribbon like, foul smelling stool.
Abdominal distention.
Fecal impaction recurs frequently. Poor appetite, poor growth
8/7/2019 congenital anomaly2011
79/129
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 as
anorectal manometry.
8/7/2019 congenital anomaly2011

8/7/2019 congenital anomaly2011
84/129
Incidence:
Intussusception is one of the mostfrequent causes of intestinal obstructions
in children between the ages of 3 monthsand 5 years. Half of the cases occur inchildren younger than 1 year, and most of
the others occur in children during thesecond year.
Etiology:
8/7/2019 congenital anomaly2011
85/129
Etiology:
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.
The most common sites:

Therapeutic Management
8/7/2019 congenital anomaly2011
90/129
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.
