This resource is a SIMM file featuring a 48-year-old male who has just started a weight loss program. After drinking alcoholic beverages last night (no active drug abuse) and using diphenhydramine for mild seasonal allergies, he set off on an uncharacteristic three-mile run on a humid, warm day. He has consequently developed environmental hyperthermia with confusion (exertional heat stroke) and significant dehydration causing renal and muscle dysfunction (acute renal failure and rhabdomyolysis). A SIMM program is needed to implement this resource.

Educational Objectives

By the end of this resource, learners should be able to:

  1. Recognize, evaluate, and manage significantly elevated body temperature in an adult patient.
  2. Recognize and manage environmental thermoregulatory (hyperthermic) disorders.
  3. Recognize the complications of heat stroke, including seizure, rhabdomyolysis, and acute renal failure.
