What the scores indicate and what three areas are being assessed?
Quick way to assess clt's neuro impairment
Highest score is 15
8 and below - clt is comatose
Lowest score is 3 (cannot be 0)
Assessment areas:
1. Best eye opening response (1-4)
2. Best verbal response (1-5)

Cheyne-Stokes respiratory pattern
Hyperventilation with alternating periods of apnea
Central Neurogenic Hyperventilation respiratory pattern

Apneustic respiratory pattern
Prolonged inspiration followed by few seconds of pause/no breathing; pons of brain stem is being affected since rate is affected
Ataxic respiratory pattern
Completely irregular breathing pattern, erratic; not going to be able to come up with definitive breathing rate
IICP (increased intra-cranial pressure)
A complication that can result from a head injury; pressure greater than 50 mmHg, potentially life threatening; anything greater than 15 mmHg is considered ICP; can result from hematoma, brain tumor, aneurysm
S/S of IICP
Earliest indications are very subtle; LOC change, irritability, anxiety, mental status continues to deteriorate, pupils may be PERRLA and then may have difference shortly after, restlessness, dec LOC; HA – sensitive to light, noise, BP and pulse changes; clt can go into coma and eventually die
Late Manifestation: Cushing’s Triad – increase in systolic BP, change in HR, widened pulse pressure (difference between systolic and diastolic)/change in body temperature
NI for IICP
Relieve the cause of pressure; Meds - osmotic diuretics (mannitol), Corticosteriods (decadron) with stool softeners, Zantac, anti-emetics, prophylactic anticonvulsant meds (Phenobarbital); NG tube to prevent paralytic ileus and gas buildup; foley - monitor I&Os; antipyretics for fever, antibiotics (prophylactic); elevate HOB 30 deg; avoid straining, suction only if needed, decrease stimuli in the area, IV fluids NS or LR - monitor for fluid overload; mechanical hyperventilation - to blow off CO2 (lowered CO2 causes vasoconstriction to slow bleeding and to decrease ICP); surgery, craniotomy, pain control

Tonic-Clonic (grand mal) seizure: Post-Ichtal (post-dromal) phase
Suction, pt may be unconscious for minutes to hours after seizure, monitor clt, when clt awakens may feel embarrassed, provide emotional support
Status epilepticus
Clt never goes into true post-ichtal phase and recovers from last seizure; continuous period of tonic-clonic seizures in which the clt does not regain consciousness; very dangerous/damaging and can be fatal - can result in brain damage, IICP
Tx for seizures
Goal is to prevent seizures, anticonvulsive medications (depakote, triliptil, neurontin), if therapeutic levels are not kept, seizures can still occur, meds may cause swollen gums, GI problems, decrease in WBC’s (klonopin)
Educate pt on medications and therapeutic levels, do not suddenly stop taking medications (especially dilantin) can have rebound effect.

• Corticosteroids – prednisone
Tx for Myasthenia Gravis
• Thymectomy – removal of the thymus gland accomplished by median sternotomy approach. Post-op: chest tube, prn meds, ventilator depending on the extent of respiratory muscle weakness
• Plasma exchange – used if patient does not respond to treatment regimen or if relapse occurs during the treatment regimen. Usually shows improvement within 24 hours however some MG patients show no improvement

-Progressive muscle weakness that develops over a matter of hours up to 10 days. Lower extremities affected first.
It is an acquired inflammatory disease that results in the demyelinization of the peripheral nerves.
-Patient has progressive ascending paralysis (paralysis starts low and it works its way up the body) that is reversible. – clt has good prognosis, very rarely does it reoccur
-Patient may be unable to walk, may fall
-Over time, upper extremities become involved, flaccid paralysis.
-Facial nerves almost always involved, bilateral facial weakness present

Spinal Cord Injury
Symptoms depend on the location of the injury; immobilize the head, neck, and back
Autonomic Dysreflexia r/t spinal cord injury
Exaggerated symptoms, injury is usually T6 or above. Precipitated by bladder or abdominal distention, fecal impaction. Severe hypertension, tachycardia, pounding HA, nausea, blurred vision, anxiety, flushed skin above the level of T-6. If left uncontrolled can lead to seizures, stroke, and death. Relieving the precipitating cause is important once it starts. Raising the HOB, remove noxious stimuli, and call MD to get antihypertensive medications to relieve the HTN. Below level of T-6 can be cool, diaphoretic, pale
Therapeutic mgmt for spinal cord injury
