  • Pupillary response

    • (+) Brain damage: lack of changes in pupil size in response to light
    • Use flashlight/penlight to assess pupillary response at bedside
  • Diagnostics
    1. Minimize emotional trauma: tell child what to expect in simple, age appropriate term, be honest about pain/discomfort, tell child it's ok to be afraid, allow child to see the equipment before test, encourage child to ask questions, allow parents to remain with child, give the child a "job" to do during the test, praise child after test
    2. Nurse should not expect cooperation from a young child: may require sedation
  • Brain scan
    • Measures gamma rays produced by the radioisotope material
    • Identify focal brain lesions, pathologic conditions (tumor, infarction, mass, vascular lesions) involving cortex in patients with headache, epilepsy, etc.
    • Test material accumulates in areas where blood-brain barrier is defective
    • Distinguishes density of various intracranial tissues & structures
  • Nursing considerations for brain scan
    1. Explain procedure to patient & family
    2. Only discomfort is IV puncture
    3. Contrast material is excreted within 6-24 hours
    4. Encourage child to drink fluid after test to aid in excretion of isotope

  • Nursing considerations for CT scan
    Explain procedure: cooperation is necessary, must lie still during procedure, show child picture of machine, may hear clicking noise as scanner moves around his head but machine won't touch him, child won't be able to eat/drink 4 hours before scan: contrast dye may cause nausea, assess for allergy to iodinated dye/shellfish, encourage to drink fluids after scan

    Explain procedure: no exposure to radiation, may talk/read to the child in the imaging room, inform parents: child may be sedated, need to be motionless during procedure, no food/fluid restriction
  • Seizure
    • Occurs when the brain functions abnormally, resulting in a change in movement, attention, or level of awareness
    • 3% of all children have seizure <15 y/o, half of which are febrile seizures
    • 1 in 100 children has epilepsy-recurring seizures
    • Disturbance in normal brain function resulting from abnormal electrical discharge in the brain, which can cause unconsciousness, uncontrolled body movement, changes in behavior & sensation, & changes in autonomic system
    • During a seizure, the neurons in the brain may fire as many as 500 times a second
  • Febrile seizure
    • Occurs when a child contracts an illness such as an ear infection, cold or chicken pox accompanied by fever
    • Most common type seen in children
  • Types of partial seizures
    • Simple partial (Jacksonian) seizure: have a motor (movement) component that is located in one portion of the body, average duration 10-20 seconds, remains awake and alert, may involve face, arms, extremities
    • Complex partial seizure: similar, except that the child is not aware of what is going on, repeat an activity, with alteration of consciousness
  • Types of generalized seizures
    • Convulsive (muscle jerking)
    • Nonconvulsive with several subgroups
  • Absence seizure (petit mal)

    Brief loss of consciousness, minimum or no alteration in muscle tone, may go unrecognized because of little change in child's behavior, abrupt onset, suddenly develops 20 or more attacks daily, look like client is staring into space for a few seconds, doesn't lead to physical injury
  • Myoclonic seizure
    Brief shock-like jerks of a muscle or group of muscles, awake and able to think clearly, don't last more than a second or two, can be mistaken for tics, tremors or clumsiness, usually involve the neck, shoulders, upper arms and often the face
  • Tonic-clonic seizure (grand mal)

    Most common and most dramatic, occur without warning, tonic phase: lasts approximately 10-20 seconds, clonic phase: lasts about 30 seconds but can vary from only a few seconds to a half hour or longer, violent jerking movements as the trunk and extremities undergo rhythmic contraction and relaxation, may foam at the mouth, may be incontinent of urine and feces, rhythmic jerking and muscle spasm, difficulty breathing and rolling eyes, sleepy and confused
  • Atonic seizure
    Sudden loss of muscle tone in the muscles that hold the body and head upright, occurs without warning and usually causes the person to fall down
  • Epilepsy
    • Refers to a pattern of chronic seizures of any type over a long period
    • A condition characterized by recurrent 2 or > unprovoked seizure in a day
    • After a 5 to 10 years seizure free, without medications, may considered to be resolved
    • Derived from the greek word for "attack"
    • Brain disorder in which clusters of nerve cells, or neurons, in the brain sometimes signal abnormality
    • Develop because of an abnormality in brain wiring, an imbalance of nerve signaling chemicals called neurotransmitters, or some combination of these factors
  • Causes of seizure
    • Vascular (Stroke, embolic stroke)
    • Infections (meningitis, encephalitis)
    • Trauma (Head trauma)
