What is heat related illness?
Heat-related illness is a spectrum of disease that occurs when the body's thermoregulatory system fails. Elevated core body temperature associated with orthostatic hypotension, tachycardia, diaphoresis, and tachypnea characterize heat exhaustion. Heat stroke is defined as elevated core body temperature plus central nervous system involvement (delirium, decreased the level of consciousness, or ataxia). Heat-related illness most often affects athletes (exertional hyperthermia), but can also occur during the warm weather months or in locations with extreme temperatures. Patients with impaired thermoregulation such as those at extremes of age, the obese or mentally ill are at higher risk. The definitive treatment for heat-related illness is total body cooling.

When available, it is recommended to place the patient on a cardiac monitor. Additionally, an intra-cavitary thermometer may be placed to monitor core body temperature closely. Commonly, esophageal, rectal, and bladder probes are used.
How to apply cold water to skin?
Continuous application of cold water to the skin can be achieved by either sponging the patient or using a spray bottle. Placing a fan to blow directly on the patient while also spraying or sponging will increase the rate of evaporation, and thereby, will more rapidly decrease body temperature. Another option is to submerge a sheet in cold water and then wring it out, and then wrap the patient in the damp sheet. This can be changed and re-submerged when it is no longer cool. The downside of these methods is that they require continuous reapplication of the water and ice to maintain efficacy.

There is limited literature comparing these devices to the traditional methods.
What is the best way to cool a patient?
However, there are obvious barriers to performing this in an emergency department. Marathons and other athletic events that see frequent heat-related illness sometimes have this capability. Evaporation (mist and fan) is the second most rapid way to cool a patient. Ice packs to the groin, axilla, neck, and areas near other great vessels have been shown to be less effective. Cooled intravenous fluids have been studied, but there is no clear consensus on their benefit (preservation of neurologic function) versus potential harm (induced shivering), but they may be considered. This activity will discuss the procedure for performing evaporative cooling with other adjunct methods in the emergency department.

What are the advantages of regional and whole body hyperthermia?
The major advantage of regional and whole-body hyperthermia is that they seem to make other forms of cancer treatment work better. Heating cancer cells to temperatures above normal makes them easier to destroy using radiation and certain chemotherapy drugs.
How does hyperthermia work?
Local hyperthermia is used to heat a small area like a tumor. Very high temperatures are used to kill the cancer cells and destroy nearby blood vessels. In effect, this cooks the area that is exposed to the heat. And, as with cooking, the higher the temperature and duration of exposure, the greater the effect seen within tissues. Thermal ablation comprises the treatments where very high temperatures cause irreversible damage to cells whereas smaller rises in temperature constitute mild hyperthermia. Radio waves, microwaves, ultrasound waves, and other forms of energy can be used to heat the area. When ultrasound is used, the technique is called high intensity focused ultrasound, or HIFU, sometimes also referred to as just focused ultrasound.
What is thermal ablation?
Thermal ablation comprises the treatments where very high temperatures cause irreversible damage to cells whereas smaller rises in temperature constitute mild hyperthermia. Radio waves, microwaves, ultrasound waves, and other forms of energy can be used to heat the area.
Can hyperthermia cause heart problems?
More serious, though rare, side effects can include problems with the heart, blood vessels, and other major organs. Since regional and whole-body hyperthermia are often given with other cancer treatments such as chemo and radiation, side effects from these treatments may be seen then or at a later time.
Why is my temperature higher than normal?
Studies suggest that this may cause certain immune cells to become more active for the next few hours and raise the levels of cell-killing compounds in the blood. Some researchers take the body temperature higher, around 107° F, for short periods of time. Other studies are testing hyperthermia and chemotherapy along with other treatments that are designed to boost the person’s immune system to help fight cancer.
