  1. Gary Clinton MS, AT/C, AT/L Sports Medicine Instructor Yelm HS WCTSMA President Heat Acclimatization? Is it necessary in Washington State?

  2. Pre-Test If a patient is suspected of Exertional Heat Stroke, what should be the first action taken in treatment of the condition? A) Drive them to the hospital by parent/yourself. B) Contact EMS and wait for them to arrive. Don’t move athlete. C) Get them a bottle of water and put ice towels on them. D) Apply Biofreeze to the entire body. E) Contact EMS, but place athlete in cold water immersion and stir the water aggressively before transport.

  3. “Another bad Summer”NATA News, Nov. 2011 • Isaiah Laurencin- FL, ExertionalSickling • Tyquan Xavier Brantley- SC, ExertionalSickling • Lewis Ogloba- PA, Asthma led to Cardiac Arrest • DJ Searcy- GA, Heat related • Forrest Jones- GA, Heat stroke • Montel Williams- AR, ExertionalSickling • Sam Dickson- PA, (Congenital)Coronary Artery • Al Smith, Jr.- TX, unknown, 2nd day of FB practice • Latrell Dunbar-MS, Cardiac Event • Candace Ortiz- TX, unknown • Angela Gettis- CA, Cardiac Event

  4. Kentucky HS Football Coach Charged with Reckless Homicide • David Stinson, head coach Pleasure Ridge Park HS criminally charged in death of 15 year old, Aug. 20th 2008. • All coaches present, AD who was present, and Principal were named in a separate civil lawsuit. • “Reckless Homicide”- When a person fails to perceive a risk that a reasonable person in that situation would have seen. • Another player that day also collapsed and spent 2 days in the hospital. • Coach alleged to have withheld water and continued practice with a heat index of 94. • Coach “would run the players until someone quit the team”. • It took 15 minutes to call 911.

  5. End results from Kentucky • Coach Stinson was on paid administrative leave, reassigned, no longer coaches. • Community & school district torn apart. • Coach Stinson was acquitted of criminal charges. • Civil suit was settled out of court for 1.75 million dollars.

  6. “Football High” Frontline documentary • Focuses on two issues in HS Football • Concussions • Heat Stroke • Arkansas, 2010 • Two heat stroke scenarios • 1 died (Tyler Davenport) • 1 lived (Will James) • What was the difference in care? • Frontline- “No one should die of Heatstroke”

  7. What does heat acclimatization mean? • A set of guidelines that safely prepares athletes for competition. • Released by the NATA in 2009 for Secondary Schools. • NFHS “A guide to Heat Acclimatization & Heat Illness Prevention” released this summer. • 7 components of plan released by NFHS this summer. • 100% of heat related deaths are preventable!! • WIAA currently has no guidelines? • Korey Stringer Institute is pushing for all 50 states to adopt guidelines for all high schools. • NCAA has had guidelines in place since 2003. • One collegiate death in August since inception! • Acclimatization is not “conditioning”

  8. Days 1-5 • No more than 1 practice per day. • No longer than 3 hours • 1 hour max. ( walk thru) permitted after 3 hours minimum rest. • Football: • Days 1 & 2 Helmets only • Days 3-5 Helmets & shoulder pads only

  9. Days 6-14 • Double practice days followed by a single • On single days, 1 walk thru permitted w/3 hrs rest. • Rest day doesn’t count towards 14 day total. • Doubles don’t exceed 3 hours for each. Not to exceed 5 hours total. • All activities included as practice time: conditioning, walk thru, weight room, etc. • Recommend certified AT onsite for all practices.

  10. NOTE: warm-up, stretching, cool-down, walk-through, conditioning, and weight-room activities are Included as part of practice time Secondary School Guidelines Preseason Heat-Acclimatization Guidelines for Secondary School Athletics. Journal of Athletic Training. 2009;44(3):332-333.

  11. Guideline contributors • National Athletic Trainers Association • American College of Sports Medicine • Gatorade Sports Science Institute • National Strength and Conditioning Association • US Army Research Institute for Environmental Medicine • American Orthopaedic Society for Sports Medicine • American Medical Society for Sports Medicine • American Academy of Pediatrics • Korey Stringer Institute is doing extensive research

  12. “Goal is all 50 States” KSI Institute • “New Jersey, first to adopt heat guidelines” • From 1995 through 2008, 39 football players died of heatstroke. • Second most common cause of death for high school athletes, after spinal cord injury. • Currently 7 states meeting guidelines WA has guidelines but is classified by KSI as deficient.

  13. Common Sense? • EAP’s in place • Earlier AM full gear practices • Shells for later PM practices, install • Emphasize pre-practice hydration • Efficient hydration available • Athlete differences • Discourage supplements, caffeine & stimulants • Lower intensity & increase breaks whenever necessary

  14. Heat Exhaustion vs. Heat Stroke • Heat exhaustion symptoms include: Paleness Cramping Heavy sweating Fainting or nausea Fast or shallow breathing Dizziness The pulse rate is fast and weak.   • Core body temperature below 104 degrees

  15. Heat Exhaustion vs. Heat Stroke • Heatstroke symptoms include both physical and neurological manifestations—a fast pulse and extremely high temperature (above 104 degrees) coupled with confusion or hallucination. • NFHS recommends taking WBGT at location • People may experience nausea, fatigue, vomiting, diarrhea, loss of balance, irritability, irrational or unusual behavior, apathy, hysteria, and headaches, as well as dizziness and disorientation.

  16. Heat Exhaustion vs. Heat Stroke • With NEHS, the body stops or decreases sweat production so the skin feels hot and dry. • With EHS, the body can still produce sweat, so the skin can be moist though the core temperature remains just as high. • Sometimes, there will be no clear evidence of a problem until the athlete collapses.

  17. Core Temperature • Is the only valid measure of body temperature. • Can only be measured rectally or with an ingestible thermometer (Gastrointestinal).

  18. Core Temperature • What if I don’t have/don’t want to measure temperature rectally? • Common sense: • Signs & Symptoms • Fast pulse • Confusion • Nausea • Disorientation • Altered level of Consciousness • Irrational/Unusual Behavior • Dizziness • Loss of Balance

  19. Exertional Heat Stroke Treatment • Activate EAP • Call 911, but… • Cool the body rapidly, before transport • Remove from heat • Cold water immersion • If not available: • Douse with cold water • Ice bags/towels, rotate : 3 mins. • Put in any available water source

  20. Cold Water Immersion • Goal is to get body temperature below 102 degrees within 30 minutes. • Water temperature between 35-59 degrees. • Ice always visible on surface • Continuously stirred. • Cooling rate in general is 1 degree: 3 minutes. • Basic guideline: • Water temp of 38-42 degree • 10-15 minutes of immersion time

  21. ExertionalSickling Signs & Symptoms Affects athletes with Sickle Cell Trait • Muscle Cramping • Pain • Swelling • Weakness • Tenderness • Inability to catch breath • Fatigue

  22. Daily Treatment of SCT Athletes • Longer periods of recovery within conditioning • Excluded from performance tests • Timed mile run & serial sprints • Adjust work-rest cycles during hotter days • Emphasize hydration • Don’t work out if feeling ill • Control asthma • Have supplemental oxygen available

  23. Proper Hydration • Study of hydration 1. Proper pre practice hydration • ½ given water • ½ withheld water • No significant difference in core temperature! 2. Start practice dehydrated • ½ given water • ½ withheld water • Significant difference in core temperature • Emphasis needs to be on effective hydration by the athlete!

  24. Preventing Sudden Death in SportsJournal of Athletic Training, February 2012 • Asthma • Catastrophic Brain Injuries • Cervical Spine injuries • Diabetes • Exertional Heat Stroke • ExertionalHyponatremia • ExertionalSickling • Lightning • Head-down contact • Sudden Cardiac Arrest 10 Most common conditions with treatment and Emergency Action Plans included.

  25. Post-Test If a patient is suspected of Exertional Heat Stroke, what should be the 1st action taken in treatment of the condition? A) Drive them to the hospital by parent/yourself. B) Contact EMS and wait for them to arrive. Don’t move athlete. C) Get them a bottle of water and put ice towels on them. D) Apply Biofreeze to the entire body. E) Contact EMS, but place athlete in cold water immersion and stir the water aggressively before transport.
