Normal Mental Status Consciousness Person is fully responsive to stimuli and demonstrates awareness of the environment Altered level of consciousness Some form of dysfunction or interruption in the central nervous system Normal Mental Status Patient is awake Patient is alert – aware of surroundings Patient is oriented to person, place, & time Patient is cooperative Patient carries on normal conversation Patient able to follow/obey commands Gait is even and steady Altered Level of Consciousness Hallmark sign of central nervous system injury or illness Did You Know? When perfusion is declining, the first indicator is a changing level of consciousness The last indicator is a falling blood pressure Assessing Mental Status - AVPU A– awake V – responds to verbal stimuli P – responds to painful stimuli U- unresponsive A – “Awake” Patient is awake, alert and aware of surroundings OR Patient may be awake but confused Report what the patient is oriented to • “Oriented to person but not place or time” Key is watching for a change in level of consciousness from the baseline taken V – Verbal Response This would need to be evaluated prior to touching the “unconscious” patient Problem: If trauma is involved, need to manually control the C-spine before causing the patient any movement of the c-spine If possible, call the patient’s name to check for response to verbal stimuli prior to making physical contact P – Painful Response Does not necessarily mean you have to perform a painful task to check for response Start with simple tactile contact – touch Add deeper stimulation if needed • Sternal rub • Pinch of thumb web space • Trapezius muscle squeeze (near neck) Do not cause so much trauma as to leave marks/bruises Observe for some kind of response with muscles Patient Response Patient response can include: Opening of eyelids even briefly Fluttering of eyelids Wrinkling of brows Most important is looking for changes in the patient’s response from one evaluation/assessment to the next U - Unresponsive The patient has NO response at all No moaning No muscle twitch at all • No eyelid flutter • No wrinkling of the eyebrow Muscles are flaccid with absolutely no response regardless of stimuli Neurological Exam In the Field AVPU – what is level of consciousness? Pupillary response Movement of distal extremities Sensation of distal extremities Wiggling fingers and toes Ability to feel contact with fingers and toes GCS <10 or deteriorating mental status patient is considered critical and categorized as Category I trauma Glasgow Coma Scale - GCS The best score possible is given More important is watching the trend than relying on any one score Objective tool All using the tool on the same patient should get the same score Evaluate Best eye opening Best verbal response Best motor response GCS – Eye Opening 4 – Spontaneous; patient’s eyes are open 3 – Eyes open or motion is made to verbal stimuli Start with soft voice, may have to yell at patient to open eyes 2 – Eyes open with tactile or painful stimuli Does not have to be focusing Start with gentle touch; may need to add more intense stimuli 1 – No eye opening; no muscle motion at all GCS – Verbal Response – Oriented to person, place, and time 4 – Pleasantly confused 3 – Inappropriate words 5 2 1 You can understand the word(s) spoken but they are not within context – Incomprehensible words – sounds No intelligible word understood; moans and groans; makes noises – Silent; no noise is made at all GCS – Motor Response – Obeys commands 5 – Localizes pain / purposeful movement 6 4 Can push you away or grab at the noxious stimuli (IV, collar, bandaging, your hands) – Withdrawal No longer localizing, just withdraws/pulls away to get away from annoying/painful stimuli (IV, collar, bandaging, your hands) Motor cont’d 3 2 1 – Flexion to pain Arms flex/bend slowly toward center of chest when any stimuli applied – Extension to pain Arms slowly extend and curl inward and legs straighten when any stimuli applied – No movement at all GCS Results range 3 – 15 Minor head injury – 13 – 15 Moderate head injury – 9 – 12 Severe head injury (coma) - <8 Score Significant mortality risk Consider intubation or other means to secure the airway GCS Practice Read the following case scenarios Determine the best eye opening, verbal response, motor response When the response is asymmetrical, award the highest points possible Don’t guess or assume what you think they really can do Award points for what is performed Be objective Note: Answers follow the practice slide GCS Case #1 Patient lying in the bed (no trauma), eyes are closed You need to yell the patient’s name and then the eyelids flicker They are mumbling They are grabbing at your hands and pushing you away. They have pulled out the IV. GCS Case #1 Score Eye opening – 3 Responded to loud voice Verbal Mumbling is incomprehensible words/sounds Motor response – 2 response – 5 Patient can recognize (localize) what feels obnoxious and what he wants to stop so they are grabbing at you and pulling at equipment Total GCS - 10 GCS Case #2 Patient is lying in the street watching you approach They mumble as you talk to them They are grabbing at your hands and pushing you away GCS Case #2 Score Eye opening – 4 Spontaneous; doesn’t necessarily indicate focusing Verbal Mumbling, moaning, groaning Motor response – 2 response – 5 Purposeful movement by grabbing at what the patient perceives as noxious stimuli Total GCS - 11 GCS Case #3 Patient watches your approach and acknowledges your presence Patient answers most questions and thinks you are their relative come to visit Patient able to move left arm to command but not able to move right arm (new onset – possible stroke) GCS Case #3 Score Eye opening – 4 Spontaneous Verbal Pleasantly confused Motor response – 4 response – 6 Highest possible score based on the arm that can and does move Total GCS - 14 GCS Case #4 Child’s eyelids flicker when deformed extremity is manipulated Child moans out when painful areas are manipulated Child pulls away when touched and tries to turn away from EMS GCS Case #4 Score Eye opening – 2 Response to painful stimuli Verbal response – 2 Moans and groans are incomprehensible words / sounds Motor response – 4 Withdrawing from what is sensed as painful stimuli Flexion would be slow flexing of arms toward center of chest – this patient’s response is not flexion Total GCS – 8 (Protect airway; consider intubation) GCS Case #5 Patient’s eyes remain closed; no eyelid movement at all There are no sounds heard from the patient The patient straightens their arms, twists their wrists, arches their back, and straightens their legs when stimulated GCS Case #5 Score opening – 1 (no response) Verbal response – 1 (no response) Motor response – 2 Eye Abnormal extension The worse level of response prior to no response at all Total GCS – 4 Patient is critical; Category I Patient usually needs some airway intervention Common Causes of Altered Mental Status A – acidosis, alcohol E – Epilepsy I – Infection (brain, sepsis) O – Overdose U – Uremia (kidney failure) T – Trauma, tumor, toxins I – Insulin – hypo or hyperglycemia P – Psychosis, poison S – Stroke, seizure Initial Patient Assessment Airway Open or obstructed Maneuvers needed to open • Head tilt / chin lift • With trauma, modified jaw thrust Breathing Quality Quantity (eyeball assessment at this time) Initial Assessment cont’d Circulation Quality Quantity (don’t count; get estimate of range) Disability AVPU GCS Expose – need to obtain baselines to examine Can’t evaluate or fix what you can’t see Assessment Tools AVPU Alert (interpreted as an awake patient) Responds to verbal stimuli Responds to painful stimuli Unresponsive Assessment Tools GCS Best eye opening response Best verbal response Best motor response Scores range from the lowest of 3 to highest of 15 Obtain and document GCS on all patient calls Cincinnati Stroke Scale Obtain for suspicion of TIA or stroke Evaluate for facial droop Check the patient’s symmetry during a broad, big smile (teeth showing) Evaluate for arm drift Check for weakness in holding arms outstretched, palms up, for 10 seconds Evaluate for clear speech Have patient repeat words listening for clear speech patterns Airway Protection and the Stroke Patient Crucial - high mortality rate for aspiration Is airway patent and can patient protect their own airway? Check if patient is able to handle & swallow own saliva • Detailed/involved swallow study done in-hospital Patient speaks in clear unobstructed voice Interventions to consider Have suction on and ready Ability to quickly turn patient onto their side FAST - Public Educational Tool Tool developed by organizations for public recognition of stroke and to encourage FAST action Region X SOP – Altered Mental Status Consider etiology If cause of problem can be identified, then interventions can be focused • Diabetes – check blood sugar • Drug overdose – what are the environmental clues • Poisoning – environmental evidence around • Alcohol related – environmental evidence; use your nose SOP – Altered Mental Status Maintain airway Patency extremely important Evaluate rate and quality If respirations inadequate, ventilate • 1 breath every 5-6 seconds all patients – infancy to elderly Intubate as necessary Use C-spine precautions as indicated If any doubt, err on side of extra precautions Provide Routine Medical Care IV – O2 - monitor SOP – Altered Mental Status Obtain blood glucose level If <60 – treat • Adult - Dextrose 50% 50 ml IVP • Child 1 – 15 – Dextrose 25% 2 ml/kg • Infant <1 – Dextrose 12.5% 4 ml/kg Dilute 1:1 ratio D 25% with normal saline Equal amounts of product make 1:1 dilution (Dextrose and normal saline) Treating Altered Mental Status In absence of IV access • Adult – Glucagon 1 unit (1 ml) IM • Pediatrics < 15 – Glucagon 0.1 mg/kg IM Max dose of 1 mg Practice math: 44 pound child with no IV access • How many kg? 44# 2.2 = 20 kg • 20 kg x 0.1mg/kg = 2 mg • How much Glucagon do you give?
