Surgical Neurological Emergencies

Reviewing the brain… Our brains are just like Emergency Room Nurses………….

Our heads are hard! The skull is hard!! It does not stretch or expand!

We are ALWAYS hungry! The brain needs a constant supply of oxygen and glucose. It cannot store glucose OR oxygen Don’t worry…..I just have time for a quick bite on the run!!!

We may be tough on the outside…..

…But we’re softies on the inside.

Increased Intracranial Pressure Neurological Emergencies July 30, 2004 Increased Intracranial Pressure The skull is a rigid box and within that box are these components Brain 80% Blood 10% CSF 10% The volume of the intracranial components must remain constant Monro-Kellie Doctrine As one component increases the other two will decrease in an attempt to compensate and thus keep ICP within normal limits, despite increasing pathology. Because of this the brain will demonstrate only slight increases in pressure over a wide range of expansion in volume. As pathology progresses, the compensatory mechanisms are depleted, which results in a rapid increase in ICP with ONLY small increase in volume. THIS produces a shift of the brain contents, with herniation of the brain through the tentorial opening, resultant pressure on the brain stem, clinical picture of altered level of consciousness as well as pupillary, motor, and vital sign changes CEN Review Course

Cerebral Compensation CSF Shunting intracerebral fluid to ventricles Too slow in trauma Brain Herniation Not user friendly to pt Blood Vasoconstriction / vasodilation I’m really in trouble now!!!

Intracranial Pressure Intracranial pressure reflects Brain Cerebrospinal fluid Blood As intracranial pressure increases, cerebral perfusion pressure decreases Leads to cerebral ischemia and hypoxia In a hypotensive patient, even a marginally elevated ICP can be harmful Adequacy of cerebral perfusion pressure is most important

Increased Intracranial Pressure Initially -intracranial volume increases-ICP remains stable. System becomes less compliant, or less able to tolerate increases in volume Later, intracranial volume cont’s to increase, less compliance will be unable to buffer the increases and ICP will rise

Increased Intracranial Pressure Neurological Emergencies July 30, 2004 Increased Intracranial Pressure Compensatory mechanisms are depleted. Results in rapid increase in ICP with only a small increase in volume. Produces a shift of brain contents to area of lesser pressure, herniation then occurs. CEN Review Course

Increased Intracranial Pressure Assessment Early picture of increased intracranial pressure (IICP) LOC Loss of insight Loss of recent memory Restless, irritable, uncooperative behavior Requires more stimulation to get same response Speech less distinct Sudden quietness in a very restless patient

Increased Intracranial Pressure Early Increasing ICP Motor function Usually contralateral to lesion Pronator drift Loss of one or more grades on the strength scale Increased tone

Increased Intracranial Pressure Early Increasing ICP Pupils Sluggish to light response Usually unilateral Ipsilateral to lesion Papilledema or bulging of optic discs Blurred vision

Increased Intracranial Pressure Early Increasing ICP Vital signs Occasionally tachycardic Occasional hypertensive swings

Increased Intracranial Pressure Late Increasing ICP LOC Arousable only with deep pain Unarousable Motor function Dense hemiparesis Abnormal flexion Abnormal extension No response (flaccidity preliminary to death)

Posturing Abnormal posturing is a late sign of increasing ICP Decorticate Abnormal flexion Decerebrate Abnormal extension

Increased Intracranial Pressure Sign & Symptoms- Impending Herniation Decreased LOC Motor Dysfunctions Pupillary abnormalities Impaired Reflexes Changes in Vital Signs Irregular respirations

Increased Intracranial Pressure Late Signs Increasing ICP Vital signs Cushing’s triad Very late sign of increasing ICP, last ditch effort to perfuse brain Elevated SBP Bradycardia Widening pulse pressure

Increased Intracranial Pressure Herniation Neurological Emergencies July 30, 2004 Increased Intracranial Pressure Herniation As ICP rises, CPP decreases, leading to cerebral ischemia and potential for hypoxia, with secondary insult CEN Review Course

Increased Intracranial Pressure Interventions ABC’s Mechanically decrease ICP Hyperventilation Osmotic Agents

Increased Intracranial Pressure Hyperventilation Goal is to keep CO2 low range of normal Lowering CO2 controversial less than 30 mmHg, may cause hypoperfusion, and can be correlated to decreasing survival rates(decreases CBF) May be needed for Brief periods- acute neurological deterioration or longer in some specific cases. Vasoconstricts vessels and reduces CBF Aggressive hyperventilation may cause cerebral ischemia

Increased Intracranial Pressure Osmotic Agents Mannitol: IV push reduces ICP within 15 minutes with continued effectiveness for 2-3 hours max dose 1gm/kg q 3 hours Monitor serum osmolarity

Increased Intracranial Pressure Treatment of ICP Easiest to manipulate is BP and CSF proper head alignment sedation Surgery

Goal Keep SBP>90

Concussion Transient impairment of neurological function caused by a mechanical force Rapid acceleration-deceleration if repeated can produce a permanent deterioration in intellect recent studies suggest long term impairment even with “moderate”concussion “moderate” if loss of consciousness

Concussion Traumatic reversible neurological deficit Reversible in minutes to hours Retrograde or antegrade amnesia

Concussion Diagnosis CT scan Clinical picture History of injury Rule out other injury Clinical picture History of injury

Concussion Interventions Assess neuro status Patient/Family education return to facility Change in LOC Change in pupils Projectile vomiting Seizure Inability to arouse

Concussion Interventions Educate patient/family Post concussion syndrome H/A Dizziness (positional) Tinnitus Inability to concentrate Personality change Memory disturbances

Concussion Interventions Educate patient/family Post concussion syndrome Duration Days to years Social/occupational Difficulty school/work

Skull Fractures Fractures Cranial vault Skull base Linear Open Closed

Basal Skull Fractures Periorbital ecchymosis (Raccoon sign) Anterior fracture

Basal Skull fracture Retroauricular ecchymosis (Battle’s sign) --Posterior fracture Blood behind tympanic membrane --Middle Fracture

Basilar Fractures cont’d If Basilar skull fracture suspected NO nasal intubation NO nasal gastric tubes

Basal Skull Fractures CSF leaks rhinorrhea (nose) otorrhea (ear) Tests for CSF: Positve glucose Positive Halo

Basal Skull Fracture VIIth (Facial) Nerve Palsy Occur immediately Occur a few days after initial injury

Skull Fractures Fragments depressed more than the thickness of the skull require surgical elevation Open or compound skull fractures Dura often torn Requires early surgical repair

Skull Fractures Complications Infections Hematoma CSF leaks Loss of smell Loss of hearing Seizures pneumocephalus

Skull Fractures Interventions Interventions ABC’s Monitor for seizures Monitor for CSF leak Avoid nasal intubation, nasal gastric tube, nose blowing, sneezing Interventions Anticonvulsants as ordered Antibiotics as ordered Possible surgery

Cerebral Contusion Cerebral contusions fairly common Mostly occur in frontal and temporal lobes Bruising of the brain tissue without puncture of pia Petechial hemorrhages Extravasation of fluid from vessels

Cerebral Contusion Distinction between contusion and traumatic intracerebral hematoma ill defined. Contusions, can evolve into an intracerebral hematoma

Cerebral Contusion Blunt force High velocity Low velocity

Coup - contracoup injury Cerebral Contusion Coup - contracoup injury

Cerebral Contusion Intervention Decrease ICP Mannitol to decrease water content in brain Increase venous outflow Discuss with family/patient evolution of contusion and need for monitoring Discuss bizarre behavior- frontal lobe Assist family in understanding a contusion to brain stem has injured “awake” center in brain

Epidural Hematoma Located outside the dura, within the skull Biconvex or lenticular in shape Mostly located in temporal or temporoparietal region

Epidural Hematoma Result from tearing of middle meningeal artery D/T fracture Bleeds arterial in origin Does not tamponade 50% mortality

Epidural Hematoma Brief loss of consciousness followed by “lucid interval” then rapidly progressive deterioration “Talk and die”

Epidural Hematoma Bleeding can rapidly become mass lesion Cause IICP Brain shift Uncal herniation

Epidural Hematoma

Epidural Hematoma Interventions ABC’s GCS <8 Decrease ICP Intubate Decrease ICP Monitor neuro status SURGERY for clot evacuation

Subdural Hematoma More common than epidural hematomas 30% of severe head injuries Tearing of bridging vein between cerebral cortex and a draining venous sinus

Subdural Hematoma Cover entire surface of hemisphere

Subdural Hematoma Presentation can be Acute < 48 hours Subacute 2 days to 3 weeks More frequent in elderly Chronic > 3 weeks

Subdural Hematoma Clinical findings range from headache with nausea to comatose and flaccid

Subdural Hematoma Non-contrast CT scan Ancillary tests Crescent shaped mass Ancillary tests CBC Chemistry Coag studies T&C

Subdural Hematoma Interventions Acute Decrease ICP Nonacute Burr holes

Subarachnoid Hemorrhage/Aneurysm rupture “worst h/a of my life” Aneurysms result from thinning vascular wall Precipitated by hypertensive event Straining Sex Heavy lifting

Subarachnoid Hemorrhage/Aneurysm rupture After rupture vessel clamps down to prevent further bleeding Result in Ischemia/infarction Blood in subarachnoid space is irritant Meningeal signs

Subarachnoid Hemorrhage/Aneurysm rupture Complications Increased ICP Vasospasm Rebleeding Ischemia Infarction Hydrocephalus

Subarachnoid Hemorrhage/Aneurysm rupture Interventions ABC’s Monitor neuro status Fluids within normal range avoid dehydration increases hemoconcentration, increases vasospasm Monitor sodium usually falls Normotensive BP until clipped then can be elevated

Spinal Cord Injuries Involve bruising or tearing of spinal cord substance from penetrating trauma or a fracture/dislocation of spinal column 15-35 year olds Usually due to trauma

Spinal Cord Injuries Mechanism of Injury Injury may involve only Axial loading Hyperflexion Hyperextension Injury may involve only Spinal cord Vertebral body Both

Spinal Cord Injuries Damage to cord From extrinsic(bony and soft tissue injury) From intrinsic (hemorrhage, edema, hypoxia, biochemical changes

Spinal Cord Injuries Classification Complete Incomplete Transection of the cord, no preservation of motor or sensory function Incomplete Some cord sparing

Spinal Cord Injuries Respiratory Complications Phrenic nerve innervates diaphragm, exits cervical cord at C-3, C-4, C-5 if involved diaphragm involved Compromises ability to breath Intercostal muscles (T-1 to T-12) involved becomes difficult to deep breath, cough

Neurogenic Shock Eliminates the “fight or flight” protective response and permits the parasympathetic system to function unopposed Results in vasodilation below level of the injury, pooling of blood, decreased venous return to the heart, and decreased cardiac output

Neurogenic Shock Loss of ability to sweat Below level of injury D/T lack of innervation of sweat glands Temperature lower than normal D/T break in connection between hypothalamus and sympathetic nervous system Loss of body heat by passively dilated vascular bed of skin

Neurogenic Shock Blood pressure may not be restored by fluids alone In trying to normalize BP may cause fluid overload, pulmonary edema BP best restored by judicious use of vasopressors May perfuse adequately without normal BP

Intravenous Fluids Quadriplegic patients-may fail to become tachycardic or may even become bradycardic in the presence of shock- due to loss of cardiac sympathetic tone.

Intravenous Fluids Hypovolemic Shock Neurogenic Shock Patient usually presents with tachycardia Neurogenic Shock Patient usually presents with bradycardia If blood pressure does not improve after fluid challenge, judicious use of vasopressors, may be indicated Overzealous fluids may cause PULMONARY EDEMA in Spinal Cord Injury Patients

Neurogenic Shock Orthostatic Hypotension Rapid drop in BP when vertical position assumed. Blood supply to brain inadequate, syncope results. (brain damage and death can result) D/T loss of arteriole vasomotor tone below level of lesion so there is pooling of blood in abdomen and LE’s when upright. Seen in patients with lesions above T-7

Spinal Cord Injuries Interventions Support BP if needed ABC’s Cervical Spine Immobilization O2 Monitor VS, CO2 Mechanical ventilation if needed Monitor LOC, UOP Enhance venous return to the heart Interventions Support BP if needed Atropine if needed Methylprednisolone NG tube Foley Attempt to have someone with patient most of the time

Autonomic Hyperreflexia Neurological Emergencies July 30, 2004 Autonomic Hyperreflexia Noxious stimuli produces sympathetic discharge that causes reflex vasoconstriction of blood vessels in skin and visceral bed below level of the injury Vasoconstriction of visceral bed distends baroreceptors in the carotid sinus and aortic arch, body attempts to lower hypertension by superficial dilation of vessels above level of injury CEN Review Course

Autonomic Hyperreflexia As spinal shock reverses, potential for dysreflexia should be considered in patients with injuries T-6 or above Nursing intervention – prevent conditions that are know to trigger autonomic hyperreflexia Causative noxious stimulus most common Distended bladder d/t kinked drainage tube

Autonomic Hyperreflexia Clinically Sudden hypertension 240/120 Pounding headache Anxious Flushed face, neck, upper chest moistened with perspiration Blurred vision Nasal congestion Nausea Lower extremities goose flesh, cold

Autonomic Hyperreflexia Interventions Elevate HOB Relieve trigger mechanism Treat hypertension as needed Resources for family/patient for self care

Medical Neurological Emergencies

Headaches Occur when there is traction, pressure, displacement, inflammation or dilation of pain receptors in brain or surrounding tissues Two types: Primary No organic cause consistently identified (migraines, cluster, tension) Secondary Organic etiology (tumor, aneurysm, meningitis, temporal arteritis)

Headaches Affects up to 75% population per year 5% will seek treatment 50 % of people with headache suffer migraine Mechanism unknown Blood vessels that supply brain and surrounding tissue narrow, reduced blood flow, followed by reflex vasodilatation, swelling, and inflammation of cerebral blood vessels

Headaches Assessment Hx of present illness Time frame onset (migraines early morning) Occurrence (in groups, then period of remission) Aura (migraines with/without aura) Duration (tension 7 days, migraine 4-72 hours)

Neurological Emergencies July 30, 2004 Stroke Clinical syndrome consisting of a neurological deficit resulting from an interuption of blood flow to an area of the brain, rapid or gradual in onset, which persists for more than 24 hours. Two types Ischemic: Thrombotic or embolic occlusion of a cerebral artery resulting in infarction Hemorrhagic: Spontaneous rupture of a vessel resulting in intracerebral or subarachnoid hemorrhage CEN Review Course

Stroke Clinical picture depends on vessel involved, extent of damage, and collateral flow 500,000 new cases per year Most common in 65 years and older 45 % are women High Risk TIA’s or previous stroke CHF, mitral valve disorders, a-fib, diabetes, HTN

Stroke Assessment Hx present illness (time pattern) Classifications of stroke: TIA – brief, lasting seconds to hours; < 24 hrs RIND – lasting 48 hours or less, complete resolution of deficit, reversible ischemic neuro deficit Stroke in evolution/progressive – Symptoms last >24 hrs with progressive neurologic deterioration. Completed stroke – permanent neurologic damage

Stroke Medical History Diabetes Rheumatic heart disease Recent MI CHF Migraines Hypertension A-Fib

Stroke Physical Exam Anterior Circulation Alteration in LOC Motor deficit Contralateral hemiparesis, hemiplegia Sensory deficit Contralateral

Stroke Diagnostic Procedures STAT CT scan MRI

Stroke Interventions Maintain airway, breathing, circulation Monitor neuro status for change Maintain venous outflow (head neutral position) Frequently monitor Cerebral function LOC Blood pressure

Stroke Interventions Supplemental oxygen, pulse oximetry RSI: sedation, neuromuscular blockers, analgesics Initiate measures to normalize blood pressure Keep SBP < 180, DBP <105 Labetalol drug of choice. Avoid rapid BP decreases. Want BP high enough to perfuse. Administer anticoagulation therapy (ischemic stroke in evolution only) May use meds to cause coagulation in hemorrhagic stroke FFP Vitamin K

Stroke Interventions Administer IV thrombolytics (ischemic stroke) Patient must present within 3 hours of onset of symptoms, CT must exclude intracranial hemorrhage

Stroke Interventions: Surgical interventions Carotid endarterectomy ( TIAs) Intra-arterial fibrinolytic therapy (6 hr limit) Angioplasty/stent placement

Shunt Problems Shunt purpose- relieve increased ICP from hydrocephalus Diversion relieves obstruction by creating alternative pathways for free circulation and/or absorption of CSF Most common complications Infections Shunt malfunction D/T obstruction(plugging by blood clots, brain or malfunction

Shunt Problems Assessment Hx of present illness Medical history Type of shunt Length of implantation Medical history Reason for shunt Previous problems with shunt Risk factors- growth

Shunt Problems Physical Exam Shunt malfunction Mental status: Decreased alertness Decreased intellectual function Behavioral changes Eye changes Inability to look up Alteration in visual acuity or fields

Shunt Problems Shunt Malfunction Incontinence Gait/coordination changes Vomiting Infant: Tense fontanelles Shrill cry Loss of appetite

Shunt Problems Physical Exam Infection Diagnostic procedures Fever Meningeal signs Altered Mental status Diagnostic procedures CT scan Lumbar puncture for CSF analysis

Shunt Problems Interventions Monitor vital signs Prepare and assist for lumbar puncture/shunt tap CSF for analysis/culture Antibiotic therapy

Seizures Sudden, paroxysmal discharge of a group of neurons resulting in transient impairment of consciousness, movement, sensation, or memory Trigger causes abnormal burst of electrical stimulus, disrupts brain’s normal nerve conduction

Seizures Causes Ionic Metabolic Nerve cell structural changes Electrolyte imbalance Metabolic Hyperglycemia Fever Stress Nerve cell structural changes Hypoxia, tumors, trauma

Seizures Classification Generalized Classification Partial Involves all areas of both cerebral hemispheres Motor manifestations are bilateral Classification Partial Focal onset involving one particular part of the brain
