DOWN SYNDROME
Most common chromosomal abnormality in children
Results from a trisomy of chromosome 21, and in less than 5% of cases, a translocation of chromosome 21
Down syndrome is associated with maternal age over 35

immune function
Endocrine dysfunctions
DOWN SYNDROME Nursing Diagnoses
Delayed growth and development
Risk for impaired parenting
DOWN SYNDROME Nursing Interventions:
Assist and support parents during the diagnostic process and management of child’s associated problems
Assess and monitor growth and development
Teach use of bulb syringe for suctioning nares
Teach signs of respiratory infection
Assist family with feeding problems
Feed to back and side of mouth
Monitor for signs of cardiac difficulty or respiratory infection

The nursing goal in caring for a child with Down syndrome is to help the child reach his or her optimal level of functioning.
CEREBRAL PALSY (CP)
Nonprogressive injury to the motor centers of the brain causing neuromuscular problems of spasticity or dyskinesia (involuntary movements).
Associated problems may include mental retardation and seizures.
Causes include:

Maternal infections
Kernicterus
Low birth weight (major risk factor)
CEREBRAL PALSY (CP)
Nursing Assessment:
Persistent neonatal reflexes (Moro, tonic neck) after 6 months

CEREBRAL PALSY (CP)
Nursing Diagnoses:
Delayed growth and development related to …….
Risk for imbalanced nutrition: less than body requirements related to…….
CEREBRAL PALSY (CP)
Nursing Interventions:
Identify cerebral palsy through follow-up of high-risk infants such as premature infants.
Refer to community-based agencies.
Coordinate with physical therapist, occupational therapist, speech therapist, nutritionist, orthopedic surgeon, and neurologist.
Support family through grief process at diagnosis and throughout the child’s life. Caring for severely affected children is very challenging.

SPINA BIFIDA
Definition:
Malformation of the vertebrae and spinal cord resulting in varying degrees of disability and deformity.
Spina bifida occulta
is a defect of vertebrae only. No sac is present, and it is usually a benign condition, although bowel and bladder problems may occur.
SPINA BIFIDA With meningocele and myelomeningocele
a sac is present at some point along the spine.
SPINA BIFIDA
Meningocele
contains only meninges and spinal fluid and has less neurologic involvement than a myelomeningocele.
SPINA BIFIDA
Myelomeningocele
is more severe than meningocele because the sac contains spinal fluid, meninges, and nerves.
SPINA BIFIDA
The severity of neurologic impairment is determined by the anatomic level of the defect.
SPINA BIFIDA
Every child with a history of spina bifida should be placed on latex precautions.
SPINA BIFIDA
Prevention:
folic acid 0.4 mg is taken daily for all women of child bearing age
SPINA BIFIDA Nursing Assessment:
Spina bifida occulta: dimple with or without hair tuft at base of spine

Associated problems:
Hydrocephalus (90% with myelomeningocele)

Congenital dislocated hips
Club feet
Skin problems associated with anesthesia below the defect
