Heat Stroke

Definition

is caused by prolonged exposure to high temperatures or by doing physical activity in hot weather.

You are considered to have heatstroke when your body temperature reaches 104 F (40 C) or higher.

Definition

When your body overheats, you first may develop heat cramps.

If you don't cool down, you may progress to symptoms of heat exhaustion, such as heavy sweating, nausea, light-headedness and feeling faint.

Clinical Classification

1. Classic heat strokeSedentary, often older or debilitated people

under conditions of high heat stress.Maybe of insidious onset (over several

days) and can present with minimally elevated core temperatures.

Clinical Classification

2. Exertional heat strokeActive, often young people, under

conditions that produce heat stress through either exertion alone or a combination of environmental thermal loading combined with physical activity

Rapid onset (within hours) and frequently associated with high core temperatures.

Clinical Classification

3. Heat exhaustionMilder form of heat illnessCore temperatures are elevated to a

smaller magnitude than in heat stroke.

Causes of Heat Stroke

2) Dehydration from not drinking enough water

1) Direct sun exposure or extreme heat

3) Being overweight, which causes the body to generate more heat and reduces the body's ability to cool down

4) Poor physical fitness or condition

5) Sleep deprivation, which can decrease the rate of sweating

6) Pregnancy

7) Some medications(antihistamines diuretics laxatives, calcium channel blockers and tricyclic antidepressants)

8) Use of illicit drugs, including cocaine, heroin, amphetamines and ecstasy (MDMA)

9) Being confined to a poorly ventilated or non-air-conditioned living space

10) Wearing bulky or heavy clothing

11)Having had heat stroke in the past

12) Lack of acclimation to hot weather or places

13) Age-related physiological changes predispose to so-called "classic" heat stroke

TREATMENT

FIRST AID

Seek medical help!

FIRST AID

Move the patient to an air-conditioned or shady area.

FIRST AID

Remove any unnecessary clothing. Expose as much of the patient’s skin surface to the air as

possible.

FIRST AID

Apply cool water to the patient’s body. Fan the patient

until his body temperature lowers.

FIRST AID

Apply ice packs to: groin, neck, and armpits

FIRST AID

Do not give aspirin or acetaminophen to reduce the

high body temperature.

FIRST AID

Give the patient fluids for hydration! (32 fl oz – 64 fl oz over 1 to 2 hours)

WaterIsotonic IV fluids (IV infusion of

N/S)

FIRST AID

Additional Information

Treatments for MH and Heat Stroke is a drug called dantrolene.

Dantrolene is used to help relax certain muscles in your body. It relieves the spasms, cramping, and tightness of muscles.

• For heat stroke, options are limited to symptomatic treatment, such as vigorous cooling and hydration. • Now, researchers at Baylor College of Medicine (Houston, TX), the University of Rochester (Rochester, NY), and the Joslin Diabetes Center (Boston, MA) have shown that a compound called AICAR, previously shown to slow muscle fatigue and increase muscle endurance, is effective in preventing heat stroke.
