This course will provide an in-depth focus on how to examine a patient for exertional heat stroke (EHS). This will include differential diagnosis from other conditions that could present as EHS, central nervous system dysfunction assessment, and body temperature assessment. Body temperature assessment will focus predominately on the use of rectal thermometry; including policy development, implementation, and specific clinical setting barriers with solutions.
Susan Yeargin is an Associate Professor of Athletic Training at the University of South Carolina. She serves on NATA’s Pronouncement’s and Research Committees. She was a task force member and author of the Pre-Season Heat-Acclimatization Guidelines for Secondary School Athletics and a co-author of the recent NATA Position Statement update on Exertional Heat Illnesses. She also serves as an expert for the Korey Stringer Institute’s Medical Board. She has 15 years of experience conducting research, over 40 peer-reviewed publications in the content area, and over 20 professional presentations at the local, national, and international level on thermoregulation and hydration behaviors. Past studies include hydration status measurements, hydration behaviors of children and adolescents, heat acclimatization of youth, pre-cooling ergogenic aids, cooling for heat illness treatment, core body temperature validity, and thermoregulation in exercising individuals. She has clinical experience with national cross country and marathon competitions as well as Division I collegiate sports. She has been a professor for 10 years teaching both undergraduate and graduate Athletic Training courses such as Preventing Sudden Death in Sport and Orthopedic Evaluation.
Defining EHS as compared to other types of hypothermia will be done in order to lay the foundation of why different temperature assessments are needed. Differential diagnosis from similarly presenting conditions will also be covered. The primary diagnostic criteria and clinical manifestation of exertional heat stroke will be reviewed throughout.
Central nervous system dysfunction is one of two key diagnostic criteria in exertional heat stroke. Central Nervous System dysfunction may manifest in a variety of ways depending on the individual patient. Understanding the range of symptoms is important in order to recognize exertional heat stroke quickly.
Examining the difference between core and shell temperature will provide a foundation to understand why temperature measurement devices provide different results. Key research examining different methods of body temperature assessment will be discussed in detail. The validity of devices will be concluded in light of the research results.
The only two measurements that can accurately assess exertional heat stroke (rectal thermometry and telemetric sensors) in the field will be focused upon. Presentation of needed equipment will be showcased for both measurement methods. A detailed description and demonstration of how to conduct a rectal thermometry assessment in clinical practice will be covered.
Purchasing, education, authorization forms, and legal nuances will be discussed when using rectal thermometry in various clinical settings. Development of policies that include rectal thermometry will be covered.
