Pediatric Neurological
Disorders
2
Increased Intracranial Pressure
3
Increased Intracranial Pressure (IICP)
What is it? Increased ICP results from a disturbance in the auto-regulation of the pressure exerted by the blood, brain, cerebrospinal fluid, and other space-occupying fluid/mass within the central nervous system. Increased ICP is defined as pressure sustained at 20 mm Hg or higher.
4
Increased Intracranial Pressure
What Causes it? Overproduction or malabsorption of CSF Space occupying lesion – tumor, hematoma Head Trauma Infection
5
Clinical Manifestations: Infant
Irritability and restlessness; high-pitched cry Full to bulging fontanels; Increase in FOC Poor feeding, poor sucking Prominence of frontal portion of the skull with distension of superficial scalp veins Nuchal rigidity Nonreactive; unequal pupils Seizures (late sign)
6
Clinical Manifestations: Child
Headache Visual disturbances - diplopia Nausea and Vomiting Dizziness or vertigo Irritability, lethargy, mood swings Ataxia, lower extremity spasticity Nuchal rigidity Deterioration in school performance, or cognitive ability
7
Severe Manifestations of IICP
Widened pulse pressure Bradycardia Irregular respirations Abnormal Posturing Decorticate (rigid flexion-upper arms extension of legs) Decerebrate (rigid extension- arms with internal rotation of arms and wrists)
8
Diagnosis Blood studies CT or MRI EEG
Lumbar puncture – may or may not be done Why?
9
What is the purpose of the following?
Medications Corticosteroid (Decadron) Osmotic diuretic (Mannitol) Sedation
10
Nursing Care Try to keep coughing, sneezing, vomiting to a minimum
When burping infant do not put pressure on the jugular vein Monitor IV rate administration Place child in semi-fowlers position Monitor VS, Neuro VS, behavior Assess for increases in ICP Assess I&O, Maintain optimal hydration Decrease stimuli, decrease pain or crying with activities Organize care, Educate parents
11
Ask Yourself What B/P would indicate a neurological problem?
12
Review What emergency equipment should the nurse have on hand at all times for a child with IICP?
13
Critical Thinking What would you expect as a first sign of IICP in an infant? What would you expect as an initial sign of IICP in a 10 year old child?

Clinical Manifestations:
Visualization of the defect Motor sensory, reflex and sphincter abnormalities Flaccid paralysis of legs- absent sensation and reflexes, or spasticity Malformation Abnormalities in bladder and bowel function
18
Diagnostic Tests: Prenatal detection Ultrasound Alpha-fetoprotein
Following Birth: NB assessment X-ray of spine X-ray of skull
19
Goals of Care Prevention of _____ to the sac preoperatively
How are these goals accomplished?
20
Nursing Intervention Keep sac moist & sterile Meticulous skin care
Protect from feces or urine Maintain NB in prone position with legs in abduction Keep in isolette
21
Post-Op Nursing Interventions
Assess surgical site Monitor VS and neuro VS Institute latex precautions Encourage contact with parents/care givers Positioning Skin Care
22

Antibiotic therapy Prevent UTI Education Emphasize the normal, positive abilities of the child
23
Critical Thinking Would you expect a 5-year-old with repaired meningomyelocele to have bladder/bowel sphincter control? Which type of neural tube defect is most likely to have no outward signs or symptoms?
24
Hydrocephalus
25
Etiology and Pathophysiology:
Imbalance between the production and absorption of cerebral spinal fluid causing Accumulation of fluid in the ventricles
26
Clinical Manifestations
Infants Increase in FOC Frontal enlargement or bossing Head larger than face Translucent skin Wide palpable suture lines Bulging Fontanels Eyes -wide bridge between Behavior changes
27
Clinical Manifestations
Children: Depressed eyes; strabismus “Setting Sun” Eyes Pupils sluggish, with unequal response to light Headache with nausea and vomiting that may be projectile S & S of IICP
28
Diagnostic Tests MRI/ CT scan Skull X-ray FOC Transillumination
**lumbar puncture very dangerous and usually NOT done
29
Bypass the blockage and drain the fluid from
Goal of treatment Prevent further CSF accumulation Reduce disability and death Bypass the blockage and drain the fluid from the ventricles to an area where it may be reabsorbed into the circulation
30
Interventions: Surgical
Ventricular endoscopy or laser Shunting to bypass the point of obstruction by shunting the fluid to another point of absorption Atrioventricular Ventricular peritoneal
31
What are the main Complications of Shunts
B___________ S___________
32
Nursing Interventions
Monitor VS and neurological status Assess functioning of the shunt Assess operative site Assess for infection Positioning of the patient Activity of patient Promote nutrition Avoid constipation Education Wear helmet
33
Critical Thinking What is the most important assessment data on a infant who has just had a shunt placement for hydrocephalus? What is the most important teaching for the parents or caregivers?
34
Cerebral palsy
35
What is it associated with?
Cerebral Palsy (CP) What is wrong? What is it associated with? Preterm Birth asphyxia Low Apgar Poor feeder Weak cry as a newborn Shaken baby syndrome Intrauterine anoxia – placental perfusion decreased
36
Assessment Determining diagnosis or extent of involvement in an infant can be difficult –may be recognizable only when child is older and attempts more complex motor skills, such as walking Jittery (easily startled) Weak cry (difficult to comfort) Experience difficulty with eating (muscle control of tongue and swallow reflex) Uncoordinated or involuntary movements (twitching and spasticity) Abnormal newborn reflexes – prolonged
37
Assessment Alterations in muscle tone Abnormal resistance
Keeps legs extended or crossed Rigid and unbending Abnormal posture Do not crawl on knees, scoot on back When try to walk, walk with toes first as in plantar flexion Scissoring and extension (legs feet in plantar flexion) Persistent fetal position (>5 months)
38
Diagnostic Tests: EEG, CT, or MRI
Electrolyte levels and metabolic workup Neurologic examination Developmental assessment
39
Nursing Care Maintain Mobility and Prevent disuse Maintain nutrition
Prevent injury and provide safety Maintain Mobility and Prevent disuse Maintain nutrition Maximize Communication ability Maintain Growth and Development
40
Complications Increased incidence of respiratory infection
Muscle contractures Skin breakdown Injury
41
Head Injuries
42
Shaken Baby Syndrome The subdural vessels are torn as the brain moves within the skull, as the brain moves over the skull floor bruising occurs, and the brain stem my become herniated with direct trauma
43
Shaken Baby Syndrome Maintain airway to prevent hypoxia and further brain damage Nurse must report to child protective service Nursing care of a child with a brain injury is similar to care of child with IIP
44
When is the child most likely to exhibit signs of an subdural hematoma?
What additional organ may have hemorrhages in the child with shaken baby syndrome?
45
Seizure Disorders
46
Seizures What are they? Brief convulsive behavior caused by abnormal discharge of neurons. The result of these discharges is involuntary contraction of muscles When numerous nerve cells fire abnormally at the same time, a seizure may result.
47
Clinical Manifestations of General Seizure/ Tonic - Clonic
Onset is abrupt. Usually less than 5 minutes duration Tonic Phase: - Usually lasts seconds - Child loses consciousness - Jaw clenches shut, abdomen and chest become rigid and may emit a cry or grunt as air is forced through the taut diaphragm. - Pale - Eyes roll upward or deviate to one side. - Arms flexed; legs, head, neck extended - increased salivation and loss of swallowing reflex
48
Clinical Manifestations of General Seizure/ Tonic - Clonic
Clonic Phase Violent jerky movements as the trunk and extremities undergo rhythmic contraction and relaxation Respirations are irregular and may have stridor May foam at the mouth Incontinent of urine and feces Afterwards Drowsy and sleep afterwards
49
Diagnostic Tests EEG CT, MRI Lumbar puncture CBC
Metabolic screen for glucose, phosphorus and lead levels
50
Maintain Patent Airway Administer medications
Goal of Care: Maintain Patent Airway Ensure Safety Administer medications Emotional support
51
What Preventive Measures does the nurse Provide?
Padded side rails, helmets to protect head O2 Setup and Suction equipment at bedside Rectal /tympanic temperatures Interventions during a seizure: Remain Calm Clear environment and make safe Maintain airway Do not attempt to restrain Turn to side Stay at the bedside and call out/emergency button for a nurse to assist you immediately
52
How does the nurse maintain the airway during a seizure
Roll to the side Loosen clothing around neck Do NOT place anything in the mouth during a seizure May give oxygen **Do not put fingers in the patient’s mouth
53
What is the priority intervention following a seizure?
Notify primary care provider Provide emotional support Reposition, provide for sleep and rest Reorient to what has happened Document
54
Seizure Medications Phenobarbital Carbamazephine – (Tegretol)
Phenytoin – (Dilantin) Diazepam – (Valium) – used mainly for status epilepticus ** Know nursing implications for each
55
Meningitis
56
Meningitis Bacterial Meningitis Viral
57
potentially Fatal What is it? Bacterial Meningitis Caused by:
Streptococcus Neisseria meningitides E coli What is it? Bacteria enters blood stream, CS fluid, and brain causing an inflammatory response. Body sends WBC and they accumulate over surface of brain causing purulent exudates
58
Viral Meningitis Same signs and symptoms, may be milder and self-limiting. Usually lasts a few days
59
Assessment Infants: Fever (not always present) Lethargy
Alterations in sleep and feeding habits Fussy and irritable Nuchal rigidity (late sign) Bulging fontanel High pitched cry
60
Assessment: Childhood & Adolescence Hyperthermia S&S of IICP
Nausea and vomiting Headache Seizures Photophobia
61
Signs of Meningeal Irritation
Headache Photophobia Nuchal Rigidy Opisthotonic position Positive Kernig’s sign Postive Brudzinski’s sign
62
Diagnostic Tests: Lumbar Puncture Serum Glucose Level Blood Cultures
63
Therapeutic Interventions Mediation Therapy
Antibiotics Ampicillin Claforan Rocephin Dexamethasone Antipyretics
64
Nursing Care Place on Respiratory Isolation until on antibiotics for 24 hours Assess vital signs and behavior Antibiotic therapy Monitor lab values Strict I&O Monitor FOC Bedrest – do not flex neck Comforting – they are very irritable
65
Downs Syndrome Trisomy 21- the most common chromosomal abnormality resulting in mild to profound intellectual Disability
66
Down syndrome Clinical Manifestations:
Congenital anomalies – cardiac and GI tract Flat facial features, nose broad and flat Low set ears Upward slanting eyes Prominent epicanthial folds Short hands with simian crease Hypotonia Neck short with extra fat pad Usually sterile
67
