Altered behavior Confusion Change in higher cerebral Change in attention Change in awareness Change in judgment function Change in memory 10 Obtaining a Baseline • Determine when patient last seen normal • Evaluate for allergies and current medications • Inquire regarding recent hospitalizations, infection, trauma, psychiatric illness • Check environment for bottles (medications, alcohol, poisonings) • Family extremely helpful to indicate subtle changes noted 11 Evidence of Changes in Brain Function • Confusion • Amnesia • Loss of alertness • Loss of orientation • Person, place, time, event • Defects in judgment/thought • Poor regulation of emotions • Disruption in perception, psychomotor skills, behavior 12 Content of Thought and Speech Evaluation • Can patient stay focused? • Is their speech tangential (abruptly moving off topic)? • Is patient oriented? • Is patient concerned and focused on the issue? • Are they asking repetitive questions? 13 “Alert & Oriented” • What is this reference to? • A & O x3 or A & O x4??? • Depending on what you test: x1 - Alert & oriented to person – their name x2 - Alert & oriented to place – do they recognize where they are x3 - Alert & oriented to time – time / day / date / season (any is reasonable) x4 - Alert & oriented to event – what just happened or what is happening 14 Components of Field Neurological Assessment • Level of alertness – AVPU and GCS scales • Ability to keep person awake • 12 cranial nerves (CN) • CN 3 (oculomotor nerve) checked in the field – pupillary response • Bilateral motor and sensory responses • Gait – not consistently able to observe in the field 15 Neurological Assessment - AVPU • An assessment scale not as detailed as GCS • Can be performed very quickly • Provides global picture of level of responsiveness • Most important is monitoring for changes in a response 16 AVPU • A – alert • Not necessarily oriented; just awake • V – responds to verbal commands • Difficult to distinguish if patient responded to voice or touch as they are often done simultaneously in the field • P – responds to pain or tactile stimulation • U – unresponsive, flaccid, no response at all 17 Glasgow Coma Scale (GCS) • Assesses overall level of arousal • Originated in Glasgow, Scotland • A tool originally designed to predict prognosis in traumatic brain injured patients • Used to diagnose, provide outcome, and evaluate progression of disease • Change in 2 or more points represents significant change in patients level of consciousness 18 GCS • Evaluate BEST RESPONSE to 3 components: best eye opening, verbal response, and motor response • Assign a score of 3 to 15 • The higher the score the more favorable the outcome • Not just useful in traumatic head injury • 13 - 15 usually indicate minor head trauma • 9 – 12 usually indicate moderate head trauma 19 GCS – Eye Opening • Need to approach patient and attempt to illicit eye opening response to verbal stimuli prior to making physical contact with the patient • Not always easy or in the best interest of the patient • May need to apply manual c-spine control as soon as patient contact made • • • • 4 – eyes open spontaneously 3 – eyes open to command spoken or shouted 2 – eyes open after painful/noxious/tactile stimuli applied 1 – no eye response at all 20 GCS – Verbal Response • 5 – oriented to person, place, time, event • 4 – confused; not oriented to person, place, time, and/or event • 3 – Inappropriate words – not able to speak in sentences; uses random words; swearing is common • 2 – Incomprehensible sounds – moaning and groaning; no distinguishable words heard • 1 – not making any verbal sounds 21 GCS – Motor Response • 6 – obeys commands • 5 – Purposeful movement – generally able to cross center of body; reaches for noxious stimuli to remove it (i.e.: IV, B/P cuff, c-collar, your hands) • 4 – Withdraws to pain – pulls arm/shoulder into body (adduction) • 3 – Abnormal flexion – arm/shoulder abducted, extremity bends/flexes • 2 – Abnormal extension – extremities straighten and rotate, back generally arches • 1- no response to all; flaccid 22 Potential Causes Altered Mental Status AEIOU - TIPS • A – Alcohol • E – Endocrine, encephalopathy, electrolytes • I – Insulin (hypoglycemia) • O – O2 (hypoxia), opiates • U – uremia (kidney disease) • • • • T – Toxins, temperature, trauma I – Infection P – Psychiatric, porphyria S – stroke, shock, subarachnoid hemorrhage, space-occupying lesion (i.e.: tumor) 23 Potential Causes Altered Mental Status SMASHED • S – substrates (glucose, thiamine deficiency), sepsis • M – meningitis • A – Alcohol, accident • S – Seizure, stimulants, hallucinogens, • E – electrolytes, encephalopathy • D – drugs (intoxication/withdrawal), illicit drugs, CO poisoning, steroids, salicylates anticholinergics • H – Hyper/hypo (B/P, thyroid, temp, hypercarbia, hypoxia) 24 Stroke • Injury or death to brain tissue • Usually from an interruption in cerebral blood flow • Tissue deprived of oxygen and glucose • 2 components brain cells rely on to function • 3rd leading cause of death and disability • Can strike any age • Increased risk with history of atherosclerosis, heart disease, or hypertension 25 Occlusive Strokes 85% Incidence • Cerebral artery blocked by clot or other foreign matter • Ischemia infarction • Embolic stroke – usually occur suddenly • A mass, generally a clot • Often a thromboemboli traveling from diseased vessels or from chambers in heart • Thrombotic stroke – usually develop gradually • Clot developed in and obstructs cerebral artery usually related to atherosclerosis 26 Hemorrhagic Strokes 15% Incidence • Usually bleeding within brain (intracerebral) or space around outer surface of brain (subarachnoid) • Onset marked with sudden, severe headache • Often related to history hypertension or congenital abnormalities in blood vessels 27 Risk Factors for Stroke Hypertension Diabetes Abnormal blood lipid levels (elevated cholesterol) Oral contraceptive use Sickle cell disease Some cardiac dysrhythmias (i.e.: atrial fibrillation) 28 Assessment of the Patient With A Possible Acute Stroke • Onset of signs or symptoms or last known normal with exact time • Blood glucose level • Cincinnati Stroke Scale • An abnormal finding in any one parameter associated with 72% probability of stroke Facial droop Arm drift Change in speech 29 Acute Stroke Assessment cont’d • Medication history of anticoagulant use • Coumadin - Warfarin • Xarelto - Rivaroxaban • Pradaxa - Dabigatran • Eliquis – Apixaban • Lovenox – Enoxaparin • History of antiplatelet use less of concern but still helpful to recognize • Aspirin and Plavix - Clopidogrel 30 Motor and Sensory Assessment • Noting that responses generated from different areas of the brain, evaluator can predict area of infarct by noting the deficit • Important to document specific results of assessments performed 31 Region X SOP – Stroke/Brain Attack • RMC • Determine time of onset / last known normal • Obtain and record blood sugar level • Intervene if <60 • Perform Cincinnati Stroke Scale • Watch for rapid neurological deterioration • Consider drug assisted intubation to protect airway if necessary 32 Rapid Neurological Deterioration • Assess patient for changes indicating a worsening of condition Unequal pupils Extensor posturing Lateralizing signs • A function attributed to one side of the brain • Evaluate for deficits from patient’s normal or baseline 33 Treatment Rapid Neurological Deterioration • Brain reliant on adequate supply of oxygen and glucose to function • Need to provide oxygenated blood • Need to avoid blowing off too much carbon dioxide to prevent potential vasoconstriction that would limit brain blood flow • Ventilate adults 1 breath every 3 seconds via BVM (20 bpm) • Ventilate children 1 breath every 2 seconds via BVM (30 bpm) • Ventilate infants 1 breath every 1.7 seconds via BVM (35 bpm) 34 Excited Delirium (ExDS) • Sudden, unexplained onset with rapid progression Delirium – fundamental manifestation Agitation Aggression Acute distress Unusual physical strength Acidosis – prominent role in cardiovascular collapse;
