Exit routes from course to medical care Urban vs rural vs wilderness access Ideal entry & exit in direction of runner flow How long to get to a fallen runner in worst case? Goals –4 minutes to CPR –8 minutes to defibrillation 10% per minute Reality –Many confounding variables –Urban vs rural –Crowd density and cooperation –Location identity –Successful resuscitation rate <50% Expectations What is our responsibility to runners? Runners safer –Race course vs training run Runners may be at more risk during a race Outcome may not always be favorable Response plan is key to race relations Managing Catastrophic Outcomes Information release policy Talk to family Chain of command The spin on death in road racing –Not every cardiac arrest will be resuscitated Goal is rapid response Reality is locating in crowd –Better chance of survival Road race vs training Adverse Event Protocol Notify Medical Director Do not discuss Controlled press release Family Information & Communication How to communicate –A medical emergency with a runner Family & friends Coaches & agents Media Considerations & Constraints Ethics Confidentiality Consent Family waiting area Separate from medical area Communications with medical area –Update medical condition –Locating lost runners Access to family for health information Family not in medical area –Confidentiality –Privacy –Blood borne pathogens –Space Caring for the Caretakers • Grief reaction among the race staff – Medical – Non medical – Runners • Post incident counseling – Accept & grow – Cannot purge memory – Avoid risky coping mechanisms • Attending the visitation Post-race Review What went right? –Most everything What went wrong? –Identify Proposed changes –Make it better New Medical Developments Collapsed athlete differential diagnosis Cardiac arrest Exertional heat stroke Hyponatremia –May present with muscle cramping –May be asymptomatic for several hours Moderate to severe EAC –Diagnosis of exclusion –Resolves with support & time –Leg elevation Defibrillators Types available –Automatic defibrillators (AED) –Manual defibrillators Locations –On site –On course AED’s on bikes expand range of care Hyponatremia Marathon & longer races 3 deaths past 18 months –2 confirmed; 1 suspected –Water excess & dilution Increased in "hot" conditions Significance –Can be fatal –Often associated with seizure Hyponatremia & Fluid Recommendations Causes –Too much fluid intake –Excess salt losses Water or hypotonic replacement Problem in longer races (>4 hrs) –Unlikely in shorter distance races –Female athletes 9:1 Parallels rise in charity running & slower average times More common in Ironman Triathlons Key history Finish time > 4 1/2 hours –Slow pace –Long duration activity with lower intensity High fluid intake –Mostly water –"2 full glasses at every water stop" Not 2 "swallows" Hot & humid conditions Key history Not acclimatized to current temp & RH Weight changes –Expect drop in weight Glycogen utilization & depletion Mild dehydration for "normal" finisher –Key weight is training weight Not pre-race weight Pre-race weight includes Glycogen loading & associated water Symptoms /Signs Early –Lightheaded –Dizzy –Nausea –Headache Severe Progressive Middle –Vomiting –"Puffy" –Muscle cramps –BP, HR, RR normal –"Impending doom" –Dyspnea –Confusion Late –Ashen, gray appearance –Prolonged seizure –Obtundation Hyponatremia Solutions Education runners –Replace sweat losses –Forget "drink as much as you can" Decrease water stops to every 3 K –Break down extra large field stops at 4 hour plus pace "Myth" information –Sports drinks do not prevent Educate volunteers Measure Na+ on site Prevention Dehydration during marathon races occurs –Rarely "severe" –More common than exertional hyponatremia –Life threatening rate similar to exertional hyponatremia? Slow competitors –Limit fluid intake & add salt to fluids Salty sweaters use salted fluids & salt food Pre-race, race, & post -race hydration recommendations Current ACSM recommendation –"Replace what you need" –Replace sweat losses Race practice has been "One size fits all" –6-12 oz each competitor every 15-20 min –Ignores individual differences Sweat rate Acclimatization Intensity of exercise Individualized Fluid Intake Calculate fluid needs –For anticipated race pace & conditions Pre- & post-run weights –Nude body weight –½ hour run Race pace Anticipated race conditions –Towel off & re-weigh nude –Fluid required / hr = weight difference (oz) x 2 Race Specific Recommendations By distance –< 20 K think of heat stoke –20-50 K think of exhaustion & exercise associated collapse –> 50 K think of hyponatremia –All think cardiac arrest By size –Very large races fluid stations –Risk of too much fluid intake Race Specific Recommendations By environment –Hot, humid –Hot –Cool –High altitude Summary Audit your race Emergency care What if...? –Its too hot –Its too cold –Someone dies –A car crashes the course Think runner safety Thank you! rober037@umn.edu
