Title: Altered Mental Status


1
  • Altered Mental Status
  • With Loss of Function

2
Neurological Deficit
  • Any deficiency in the functioning of the brain or
    nervous system
  • Nontraumatic brain injuries

3
Stroke (CVA)/Brain Attack
  • Most common condition causing altered mental
    status
  • Interruption of blood flow to the brain
  • Aphasia (loss of speech)
  • Anesthesia (loss of sensory function)
  • Plegia (paralysis)(loss of function)
  • Paresis (weakness) (loss of function)
  • Most common cause of death
  • More than half victims die
  • Others suffer permanent neurological damage

4
Stroke (CVA)/Brain Attack Cont..
  • Most often affect the elderly
  • Atherosclerosis
  • Arteriosclerosis
  • Hypertension
  • Episodes of TIAs

5
Signs Symptoms
  • Loss of speech, sensory motor function
  • Decreased LOC.
  • Severe headache
  • Drooping eyelid and mouth on one side
  • Monoplegia (one extremity)
  • Hemiplegia (one side of the body)
  • Dysphasia (difficulty speaking or swallowing)
  • Dyspnea
  • Possible seizures

6
Transient Ischemic Attack (TIA)
  • Mini-stroke
  • Signs symptoms often disappear within 24 hours
    with no permanent disability
  • Ischemia - oxygen deficit in the tissues
  • Most commonly signs and symptoms last for
    approximately 5 to 10 minutes. Unusual to last
    longer than 30 minutes
  • Approximately 1/3 who suffer TIA will have a
    stroke

7
Occlusive Strokes
  • Thrombosis
  • Embolism

8
Thrombosis
  • Thrombosis - process of clot formation
  • Thrombus - clot at the site of occlusion
  • Atherosclerosis (plaque deposits)
  • Hypertension( wearing out of the walls, plaque)
  • Builds up over a loner period of time
  • Onset of signs and symptoms slower than
    embolic-type
  • Most common type of stroke
  • Most commonly occurs at night when patient
    awakens with loss of speech, motor, and sensory
    functions

9
Embolism
  • Clot travels from one area of the body, usually
    the neck or heart and lodges in the cerebral
    artery.
  • Blood clot
  • Air bubbles
  • Tumor fragments
  • Fat particles
  • Most often occurs when patient is awake and
    active
  • Sudden onset of signs symptoms
  • Headache, seizure activity, brief periods of
    unresponsiveness are more common

10
Hemorrhagic Stroke
  • Rupture of an artery causing bleeding within the
    brain
  • Hypertension - causes wall to weaken(aneurysm)
  • Congenital defect
  • Onset sudden
  • Severe headache (worst headache I ever had)
  • May or may not have mental distortion
  • Seizures and stiff neck are also common

11
Scene Size-up
  • Scan the scene for clues of medical or trauma
  • Look for evidence of drug paraphernalia, alcohol,
    or prescription drugs.
  • Note patients cloths (bed clothes)
  • Look for bucket or ice pack near the bed
  • NV or headache

12
Initial Assessment
  • Establish airway
  • Suction (lost ability to swallow due to
    paralysis)
  • Establish positive pressure ventilation with
    BigOs
  • NPA or OPA
  • It is possible for patient to feel pain but not
    be able to move in response to it

13
Focused History/Physical Exam
  • If patient is unresponsive
  • Perform physical exam
  • Obtain baseline vitals
  • SAMPLE history
  • If patient is responsive
  • Perform SAMPLE history
  • Physical exam
  • Baseline vitals

14
Focused History/Physical Exam Cont..
  • Assessment will be rapid rather than focused
  • Assess speech
  • Assess face for drooping and pupils for equality
  • Assess grip strength bilaterally
  • Baseline vitals every 5 minutes document
  • Remember hypertension is a good indicator

15
SAMPLE History
  • Medic alert tags
  • Determine response to commands
  • Blink yes or no
  • Squeeze your finger if patient understands
  • Any recent history of trauma to the head
  • Any history of previous stroke
  • Any seizure activity prior to arrival
  • What was the patient doing at time of onset
  • Any history of diabetes
  • Any complaint of headache or stiff neck

16
Other Questions
  • Any anticoagulant drugs
  • History of hypertension
  • Has patient taken any amphetamines, cocaine, or
    other stimulant drugs
  • Was onset gradual or sudden
  • Did signs symptoms get progressively worse or
    better
  • Any paralysis or weakness progressing to other
    areas

17
Detailed Ongoing Assessment
  • Do a detailed exam if time permits
  • Perform ongoing assessment every 5 minutes
  • Document and record any changes and all vitals

18
Emergency Treatment
  • Ensure airway
  • Oxygen therapy NR mask or positive pressure
    ventilations with Big Os
  • Position patient
  • Altered mental status left lateral recumbent
  • Responsive supine semi-fowlers or fowlers
  • Protect paralyzed extremities
  • Transport
