Concussion Management Flashcards

1
Q

Concussion Definition

A
  • Sport-related concussions a traumatic brain injury caused by a direct blow to the head, neck or body resulting in an impulsive force being transmitted to the brain that occurs in sports and exercise-related activities
  • This initiates a neurotransmitter and metabolic cascade, with possible axonal injury, blood flow change, and inflammation affecting the brain.
  • Signs and symptoms may present immediately or evolve over minute or hours, and commonly resolve within days, but may be prolonged.

Q

What does a concussion entail?

A
  • Functional injury
  • Acceleration or deceleration injury of the brain
  • Do not have to be ht in the head to have a concussion
  • No abnormality seen on standard neuroimaging
  • Brain is like Jell-O and neurons get stretched
  • Depolarization of neurons (number of symptoms)
  • Energy crisis

Q

Suspected Concussion - on field

A
  • Athlete down on field
    1. Stabilize the neck and instruct not to move
  1. “What is your name?” (1st question always)
  2. If responsive, ask the following questions (orientation)
    * Where are you? What day is it? What is the score?
  3. What are you feeling? (symptoms)
    *HA, dizziness, nausea, ringing in ears, blurry?
  4. Do you have any pain in your neck?
  5. Do you have any pain in your
    arms/legs?
  6. Assess sensory of extremities while stabilizing the neck
  7. Assess active movement of
    extremities
  8. Have athlete rotate neck side to
    side (must be able to turn head >45˚ each direction without pain)

Q

Suspected Concussion - sidelines

A
  • If athlete comes off under own power, but you are suspecting concussion
  • Sit them down immediately
  • Maddock’s questions (tailor to sport)
  • Where are we today? (venue)
  • What period/half is now?
  • Who scored last in this match?
  • What team did we play last
    week/game?
  • Did your team win the last game?
  • Ask about their symptoms
  • if any symptoms, pull from the game
  • No medications
  • SCAT-6
  • Remove gear and sit in shade

Q

Concussion Diagnosis

A
  • Rule out cervical fracture or more serious injury
  • Do not leave athlete alone
  • When in doubt, sit them out!
  • Monitor for 2-3 hours
  • Do not allow athlete to sleep for at least 3 hours after concussion
  • No longer need to wake up throughout first night

Q

Concussion for parents/coaches

A
  • If you observe any of the following or are unsure, go to ER
  • Severe or worsening headache
  • Very drowsy or can’t be awakened
  • Seizures
  • Decreasing level of consciousness >2 hours after injury (cannot
    recognize people or places)
  • Unusual behaviour, very confused, very irritable

Q

Concussion Assessment

A
  • Vital Signs: to establish baseline
  • Physical signs: pupil abnormalities
  • Cognitive Assessment
  • Balance Assessment

-Coordination Assessment

  • Sport Concussion Assessment tool (SCAT-6)
  • Assesses these elements
  • Standardized tool for evaluating concussions
  • Used for athlete 13 years and older
  • 12 year and younger use Child SCAT-6

Q

SCAT-6 test

A
  • 10 – 15 minutes to perform
  • Complete as baseline or within first 72 hours of concussion
  • Immediate assessment tool (maximum utility)
  • Return to play or >72 hours use SCOUT 6 (Sport Concussion Office
    Assessment Tool)

Q

Concussion Management

A
  • Diagnosis has beed made and red flags ruled out
  • Eduction & reassurance
  • One of the best ways to reduce the incidence of persistent symptoms
  • What is a concussion? Your brain is not damaged – this is temporary
  • What are you likely to experience?
  • What things you can do to improve your outcomes? Sense of control
  • Prognostic Variables
  • High symptoms severity score (also related to anxiety & poor coping skills – increased
    education & reassurance needed)
  • Pre-existing mental health status (anxiety & depression)
  • Early removal from play
  • Male/female
  • Time from injury assessment

Q

Rest after a concussion

A
  • There is currently insufficient evidence that prescribes complete rest

-After a brief period of rest during the acute phase (24-48 hours) after injury, patients can be encouraged to become gradually and progressively more active

  • Stay below their cognitive and physical symptoms worsening

Q

Concussion Facts

A
  • 93% of people are
    back to school fulltime by 10 days
  • Decrease use of screens and phones the first 24-48 hours
    has a better recovery outcome
  • Get back to movement and learning early is helpful
17
Q

Return to Learn (RTL) strategy

A
  • Following an initial period of relative rest (24–48 hours following an injury at Step 1), athletes can begin a gradual and incremental increase in their cognitive load. Progression through the strategy for students should be slowed when there is more than a mild and brief symptom exacerbation.

*Mild and brief exacerbation of symptoms is defined as an increase of no more than 2 points on a 0–10 point scale (with 0 representing no symptoms and
10 the worst symptoms imaginable) for less than an hour when compared with the baseline value reported prior to cognitive activity.

18
Q

Recovery Stages of concussion

A
  1. Symptom limited activity
  2. Light cognitive activity
  3. Half day of school or work
  4. Full day of school or work
  5. Return to physical activity
  6. Sport specific activity
  7. Non-contact training
  8. Medical clearance
  9. Full practice
  10. Game play
19
Q

Persisting Concussion Symptoms (PCS)

A
  • Symptoms greater than 4 weeks after injury:
  • Headache
  • Dizziness
  • Fatigue
  • Irritability
  • Sleep problems
  • Concentration problems
  • Memory problems
  • Problems tolerating
    stress/emotion/alcohol
  • Other problems may exist prior to injury
  • These can co-occur or mimic persisting symptoms but do not arise from concussion
20
Q

Pathophysiology PCS

A

Main Theories:
1. Blood Flow Abnormalities (physiological)

  1. Metabolic, Inflammatory, or Hormonal
  2. Visual and/or Vestibular Dysfunction
  3. Cervical Spine Dysfunction
  4. Psychological
