NEUROLOGICAL FUNCTION
IN PEDIATRICS CH 29
Christine Limann Dyer, RN, MSN, CPN
Pediatric Differences

young child
A & P Review

Nervous system
 Central
 Brain
nervous system
and spinal cord
 Peripheral
nervous system
 Sensory-somatic
 Autonomic
Altered States of Consciousness


Arousal or level of consciousness: awareness of the
environment
Content of thought: all cognitive functions that
ensure awareness of affective states, self, and
environment
The Unconscious Child

Unconsciousness is a state in which a child’s cerebral
function is depressed and ranges from stupor to
coma
Caring for the Unconscious Child

Evaluating
neurological status
 The
pediatric Glascow
Coma Scale
 Eye
opening, verbal
response, and motor
response
Caring for the Unconscious Child






Monitor vital signs
Manage the airway
Manage bladder and
bowel elimination
Maintain hydration &
nutrition
Provide proper
hygiene
Position and perform
exercise
Persistent Vegetative State



A complete unawareness of the environment
accompanied by sleep–wake cycles.
The diagnosis is established if it is present for 1 month
after acute or nontraumatic brain injury or has lasted
for 1 month in children with degenerative or metabolic
disorders or developmental malformations
Family support is needed
Increased Intracranial Pressure


Intracranial pressure (ICP) is the pressure of the
cerebral spinal fluid (CSF) in the subarachnoid space
between the skull and the brain. A child can have
increased ICP as a result of many internal or external
factors.
Signs and symptoms
