Title: Head Injury Management Concussion Evaluation
1Head Injury ManagementConcussion Evaluation
Sports Medicine Mr. Smith
2Todays Agenda
- Discuss arrival assessment
- Discuss full head injury evaluation in HIPS
format - Discuss deadly head injuries
- Discuss second impact syndrome
- Practice
3Arrival Assessment
- What you should observe as you are approaching
the downed athlete - Are they moving? Limbs? Eyes?
- Body position?
- Decerebrate and decorticate rigidity?
- Prone? Supine? Neck angle?
- Level of consciousness
- Unconscious and not breathing
- Unconscious and breathing
- Conscious
4On Field Assessment
- When you get to the athlete
- One immediately stabilizes the head, while
another performs the evaluation - Check ABCs- begin CPR? AED?
- Determine level of consciousness (LOC)
- If unconsc and not breathing- begin CPR/ AED
- If unconsc and breathing- treat as if a neck fx
- If consc- continue with eval
- Check ears and nose- presence of CSF
- Quick body visual for gross deformities and/ or
bleeding - Check vitals- respiration, pulse, blood pressure,
pupils
5On Field Assessment
- If theyre conscious and moving their limbs as
you are approaching, should you still immediately
stabilize the head and neck? - If theyre conscious and you stabilize the head
and neck, how long should you continue to
stabilize? - If they are unconscious ALWAYS treat like a
cervical fracture with head trauma
6HIPS Evaluation
- History
- Mechanism- Ask them how they got hurt and then
ask someone else who witnessed the trauma, if you
didnt, to confirm their memory - Previous concussion(s)?
- Any unusual sensations? Pain, numbness? Can they
move their hands and feet? Headache, nausea,
blurred vision, tinnitus? - Where is pain located? Head, neck?
7Mechanism of Injury Coup and Contrecoup
8Signs and Symptoms of a Concussion
- Headache
- Balance problems
- Dizziness
- Concentration difficulties
- Loss of consciousness (LOC)
- Lightheadedness
- Delayed motor/ verbal response
- Memory or cognitive dysfunction
- Disorientation
- Amnesia
- Blurred vision
- Vacant stare
- Photophobia
- Tinnitus
- Nausea
- Vomiting
- Emotionality
- Slurred speech
9HIPS Evaluation
- Inspection
- Working with these athletes daily give you the
advantage, because you know how each person
NORMALLY acts and what their normal personality
is. - Visual inspection of athletes disturbances in
coordination, orientation, attention, emotional
response, verbal and motor response, and physical
deformity such as swelling, bleeding, fluid from
ears or nose etc.
10HIPS Evaluation
- Make sure the following have been checked
- ABCs
- Vitals- heart rate, blood pressure, pulse
- Pupils- Pupils Equal And Reactive to Light
(PEARL) - Otorrhea, rhinorhea, Battles sign, raccoon eyes,
hyphema, nystagmus 911
11Pupillary Response
12Ottorrhea
13Basal Skull Fracture
14Battles Sign
15Racoon Eyes
16Hyphema
17Subconjunctival Hemorrhage
18Nystagmus
19HIPS Evaluation
- Palpation
- Skull- feel for tenderness, depressions
- Cervical spine- pain over the spinous processes?
- Sensation in extremities?
- This is point in which you completely rule out a
cervical fracture - IF this is deemed within normal limits, you can
stop stabilizing the head - IF pain or numbness occurs, stabilize head until
paramedics arrive. Do not give head to anyone.
20HIPS Evaluation
- Special Tests
- Memory Check- retrograde, anterograde amnesia
- Anterograde amnesia- after the brain injury
- Example Remember these three words.
- Have athlete repeat words back to you every five
minutes - Retrograde amnesia- before the brain injury
- Example What team are you playing?
- Presence of sustained (gt30 minutes) antero
amnesia 911 - Keep asking questions- date, location, who scored
last point, what they ate for breakfast etc.
21HIPS Evaluation
- Balance/ coordination
- Rhombergs test
- Heel to toe walking
- Reflexes
- L4- L5 Patellar tendon reflex
- PEARL
- S1- S2 Achilles tendon reflex
22HIPS Evaluation
- Cognitive Functioning- count backwards from 100
by 7s or repeat the months backwards - Halo Test- for presence of CSF
23HIPS Evaluation
- Cranial Nerve Assessment
- Cranial Nerves 1-12
- Both sensory and motor
- Need to be rechecked every 20 minutes until
severity of trauma is established
24 Cranial Nerve Name Acronim
1. I Olfactory On
2. II Optic Old
3. III Occulomotor Olympus
4. IV Trochlear Towering
5. V Trigeminal Top
6. VI Abducens A
7. VII Facial Fin
8. VIII Auditory And A

11. XI Spinal Accessory Some
12. XII Hypoglossal Hops
25(No Transcript)
26Cranial Nerve What action tests each nerve
I- Olfactory Ask if they can smell ammonia salts, tuft skin, perfume. Etc.
II- Optic Ask athlete to read the score board, look at cars in the distance
III- Occulomotor PEARL
IV- Trochlear Roll their eyes, follow your finger downward and inward
V-Trigeminal Bite down, clench jaw, sensation in cheeks
VI- Abducens Follow your finger outward
VII- Facial Raise eyebrows, smile, frown
VIII- Auditory Close eyes balance on both legs, balance one leg, close eyes balance on one leg, heel to toe walking, finger to nose
IX-Glossopharyngeal Swallowing
X- Vagus Stick out tounge and say ahhhh
XI- Accessory Resist the athlete doing a shoulder shrug
XII-Hypoglossal Stick out tounge and wiggle it around
27Grading systems for the severity of a concussion
Grade or level Cantu (2001) Colorado Medical Society (1991)
1st degree No LOC, postraumatic amnesia or postconucssion signs or symptoms lasting less than 30 minutes No LOC, confusion, no amnesia
2nd degree LOC lasting less than 1 mintues, postraumatic amnesia or postconcussion signs or symptoms lasting longer than 30 mintues but less than 24 hours No LOC, confusion, amnesia
3rddegree LOC lasting more than 1 minute or posttraumatic amnesia lasting longer than 24 hours, postconcussion signs or symptoms lasting longer than 7 days LOC
28Glasgow Coma Scale

31Normal Concussions
32Quick Brain Anatomy
33Dangerous Concussions
- Epidural Hematoma
- Sits outside of dura mater in between skull
- Signs and Symptoms include
- Altered state of consciousness, nystagmus, pupil
inequality, irregular eye movement, slowing of
heart rate, irregular respirations, severe
headache, vomiting, unable to perform
coordination tests, decreased muscle strength,
seizures, cranial nerve assessment tests are all
not normal
34Very Dangerous Concussion
- Subdural Hematoma
- Collection of blood between the dura and the
arachnoid space of the brain - Commonly delayed onset of symptoms (2 days- 2
weeks) - High mortality rate
- Signs and Symptoms
- LOC, irritability, seizures, numbness, headache,
dizziness, disorientation, amnesia, weakness,
nausea, vomiting, personality changes, inability
to speak, slurred speech, difficulty walking,
blurred vision, deviated gaze or abnormal
movement of eyes
35Epidural vs. Subdural
36Consequences of returning to athletic
participation too soon
- Second Impact Syndrome
- Deadly!! Can take only minor blow the second time
to create life threatening situation - Loss of auto regulation of the brains blood
supply vascular engorgement in the cranium
increased intracranial pressure the second blow
bursts the engorged area - Death in nearly 50 of all cases, disability in
almost 100 of all cases 911 maintain vitals if
possible - THIS IS WHY WE TREAT ALL CONCUSSIONS
CONSERVATIVELY
37Preston Plevretes
- Second Impact Syndrome-
- Second Impact Syndrome happened to young man
while in freshman year of college during football
game - Sustained initial injury 4 days before 2nd injury
- Four and a half years later, Plevretes struggles
to walk and talk and needs round-the-clock care - ALL BECAUSE CONCUSSION WENT UNDIAGNOSED!!!

- Questions? Comments? Concerns?
- A lot of information to digest.. But with
practice, it will become MUCH easier to
understand - Practice time!!!
