NCTC 4th semester test 3

QuestionAnswer
Guillain-Barre syndrome Usually reversible and survivable Is the leading cause of acute flaccid paralysis most common presentation is characterized by ascending, symmetric paralysis that usually affects the cranial nerves and the autonomic nervous system
Guillain-Barre syndrome - Stages Acute stage can last up to 4 weeks plateau stage lasting from a few days to a few weeks, in which signs and symptoms remain constant. recovery stage, characterized by gradual improvement in signs and symptoms
What causes Guillain Barre Syndrome? May experience onset of signs and symptoms 1 to 3 weeks after an acute viral infection that was respiratory or gastrointestinal (GI) in origin Incidence increases generally with age, peaking most sharply from ages 50 to 74
Guillain Barre Syndrome s/s Motor weakness and paralysis usually begin in the legs, progressing to the trunk and arms. **Areflexia is considered a key assessment finding in GBS Cranial nerve involvement is present in 85% of cases
Diagnostic criteria for GBS progressive weakness of two or more limbs caused by neuropathy * areflexia * history of recent viral infection * elevated protein levels in cerebrospinal fluid (CSF) abnormal electromyography (EMG) results
Circle of Willis where many arteries anastomose together at base of brain Most common area for aneurysm formation, especially at midlife Congenital malformation of this area in half human population
Cranial Nerve 1 Smell - odor identification each nostril
Cranial Nerve 2 Vision - Central, peripheral, light/dark, read words
Cranial Nerve 3 Eye Motor - Move up/down/in, PERRLA, Raise eyelids, Constrict pupils
Cranial Nerve 4 and 6 Eye Motor - Move eyes down/in (4) outward (6)
Cranial Nerve 7 Face and Taste - Taste anterior 2/3 tongue, Make faces (smile, winch, puff cheeks, note symmetry)
Cranial Nerve 8 Hearing - Acuity of words or tuning fork test
Cranial Nerve 9, 10 Speaking - Swallowing, hoarseness, uvula symmetry, gag reflex
Cranial Nerve 11 Shrug- Shoulder muscle strength
Cranial Nerve 12 Tongue - Note deviation to one side, push tongue against cheek
Autoregulation Brains are self-protective and attempt to prevent hyperemia or subflow states by regulating diameter of arterioles Done by controlling pressure and chemistry ↑BP or ↓PaCO2 = constriction ↓BP or ↑PaCO2 = dilation
Cerebral Lobes - Frontal (motor strip) voluntary motor, intellect, judgment, personality
Cerebral Lobes-Parietal (sensory strip) sensory speech, sensory for opposite side of body
Cerebral Lobes - Temporal (hearing, speech, emotions)
Cerebral Lobes -Occipital (vision)
Cerebellum Lies behind the brain stem (lower back of brain) Motor center (muscle tone, posture, locomotion, coordination)
Autoregulation Done by controlling pressure and chemistry ↑BP or ↓PaCO2 = constriction ↓BP or ↑PaCO2 = dilation
Possible Therapies for Increased ICP/Preventing Secondary Brain Injury Positioning of patient Maintain normal serum glucose Avoid noxious stimuli Avoid clustering activities Avoid Valsalva maneuver Avoid excessive suctioning Maintain adequate oxygenation Maintain PaCO2 between 35-40 Volume Resuscitation
Possible Therapies for Increased ICP/Preventing Secondary Brain Injury Mannitol May cause rebound effect in hours (increase in ICP after Mannitol wears off), so often given with Lasix Observe for dehydration Observe Na+, K+, Cl- levels every 4-6 hours Must use IV filter with Mannitol, must be warm or will crystallize
Possible Therapies for Increased ICP/Preventing Secondary Brain Injury Lasix With Mannitol to pull fluid from vascular system into urine May decrease CSF production Induced Hypothermia after head injury
Possible Therapies for Increased ICP/Preventing Secondary Brain Injury Drainage of CSF Cerebyx or Dilantin IV Diamox Barbiturate Coma Neuromuscular Blockers Sedatives & Hyponotics Nimotop Steroids Avoid vasodilatory drugs Hypervolemia/Hemodilutional/Hypertension
Doll’s Eyes Oculocephalic – evaluates brain stem function (nerves 3,6,8) Briskly rotate head Present (eyes should move in opposite direction of head) Absent (eyes do not move in sockets but follow passively) indicates severe lesion of brain stem
Oculovestibular – evaluates brain stem function Ice water into patient’s ear canal Intact reflex (normal to have nystagmus, deviate toward the side with cold fluid and move away rapidly, nausea Abnormal (asymmetrical movements) Absent reflex (passive eye movements)
Intracranial Aneurysm/Subarachnoid Hemorrhage Nimotop (Ca channel-blocker selective to intracranium) prevents vasospasm Hypervolemia/hypertensive/hyperdilutional therapy (Triple H) includes Iv Fluids, Dopamine, Albumin or other volume expanders
Spinal Shock Temporary flaccid paralysis and loss of reflexes below lesion Hypotension and bradycardia and maintaining body heat are problems
Autonomic Dysreflexia An over reaction to the sympathetic nervous system in patients with injury T6 or above Check first for distended bladder or obstructed urine output Check next for bowel distention/impaction Elevated BP most threatening symptom
Precipitating Factors for Autonomic Dysreflexia Scrotal compression, Epididymitis, Ejaculation, Sexual intercourse, menstruation, pregnancy, uterine contractions/vaginal child birth, vaginitis Constrictive clothing/appliance, bone fractures, surgical procedures, pain, temperature fluctuations
Myasthenia gravis - Symptoms weakness of the voluntary (skeletal) muscles worsens with activity and improves with rest. Breathing difficulty because of weakness of the chest wall muscles Chewing or swallowing difficulty,
myasthetnic crisis life-threatening breathing problems.
