Overview
- Heatstroke is a condition caused by your body overheating, usually as a result of prolonged exposure to or physical exertion in high temperatures. This most serious form of heat injury, heatstroke, can occur if your body temperature rises to 104 F (40 C) or higher. The condition is most common in the summer months.Heatstroke requires emergency treatment. Untreated heat…
Treatment
- Heat stroke is a medical emergency; any signs or symptoms of this condition should prompt a call to emergency services (911). Meanwhile, immediately begin first aid by cooling the person move them to shade or an air-conditioned building, remove constricting or clothing layers, and cool the person with evaporative cooling (mist or spray water on the patient while fans are running). Som…
- The initial treatment of patients with heat exhaustion involves stabilization in a cool area. Unless the factors leading to heat exhaustion are corrected swiftly, affected patients can progress to heatstroke. An algorithm for the management of heat exhaustion and heatstroke is provided in Figure 1. Evaporative cooling may be initiated by wetting the skin. Electrolyte status and core te…
- There are some medications that can affect a person's response to heat and ability to stay hydrated. These include vasoconstrictors (which narrow blood vessels), diuretics (which reduce sodium and water in the body), beta blockers (often found in blood pressure medications) and some antidepressants and antipsychotic medications. Move the patient to a cooler environmen…
Signs And Symptoms
- Heatstroke signs and symptoms include: 1. High body temperature. A core body temperature of 104 F (40 C) or higher, obtained with a rectal thermometer, is the main sign of heatstroke. 2. Altered mental state or behavior. Confusion, agitation, slurred speech, irritability, delirium, seizures and coma can all result from heatstroke. 3. Alteration in sweating. In heatstroke brought on by h…
- Heat exhaustion is a more common and less extreme manifestation of heat-related illness in which the core temperature is between 37°C (98.6°F) and 40°C. Symptoms of heat exhaustion are milder than those of heatstroke, and include dizziness, thirst, weakness, headache, and malaise. Patients with heat exhaustion lack the profound central nervous system derangement found in t…
- First, it's important to take heat stroke seriously. The risk of death is very real in someone who's in this condition. Signs and symptoms of heat stroke include confusion, hot, flushed, dry skin, deep, rapid breathing and in some cases, seizures.
Cause
- Heatstroke can occur as a result of: 1. Exposure to a hot environment. In a type of heatstroke, called nonexertional (classic) heatstroke, being in a hot environment leads to a rise in core body temperature. This type of heatstroke typically occurs after exposure to hot, humid weather, especially for prolonged periods. It occurs most often in older adults and in people with chronic i…
- The major cause of heat stroke is prolonged exposure to high temperatures and/or doing strenuous activity in hot weather. The body's ability to control the core temperature (sweating, evaporative cooling, for example) is overwhelmed by heat. Another cause of heat stroke that often results in death is leaving a child or pet in a vehicle that is not well ventilated or cooled. The aver…
- Heatstroke and heat exhaustion occur when the bodys thermoregulatory responses are inadequate to preserve homeostasis. This can result from extrinsic factors that make heat dissipation less efficient, such as extremes of temperature, physical effort, and environmental conditions. It also can result from physiologic limitations, putting children, elderly persons, and t…
- A rapid heartbeat and a lack of sweating in a hot environment are also possible signs of heat stroke. If a person is incoherent and disoriented as well as having these other symptoms, chances are strong they're already in the midst of heat stroke, and quick action is needed.
Prevention
- Heatstroke is predictable and preventable. Take these steps to prevent heatstroke during hot weather: 1. Wear loosefitting, lightweight clothing. Wearing excess clothing or clothing that fits tightly won't allow your body to cool properly. 2. Protect against sunburn. Sunburn affects your body's ability to cool itself, so protect yourself outdoors with a wide-brimmed hat and sunglasse…
- Preparation for and understanding of heat-stroke can help prevent much of its associated morbidity and mortality.29 Physicians should encourage their patients to protect themselves by maintaining adequate hydration, avoiding heat exposure, wearing loose, light clothing, and monitoring their exertion level.9 Athletes should be advised to acclimatize for at least three to fo…
- Be careful if you encounter a patient of heat stroke. If the environment is hot enough for the patient to get overheated, then it's hot enough for a rescuer to become overheated as well. Follow universal precautions, which include hand washing and wearing gloves or other personal protective equipment if you have it.
Prognosis
- With quick and effective treatment, many people will recover with little or no problems, although some may become more sensitive to hot weather. Initial recovery takes about 1-2 days in the hospital; longer if organ damage is detected. Experts suggest that complete recovery from heat stroke and its effects on the internal organs may take 2 months to a year. However, the prognosi…
- Symptoms of heat exhaustion often resolve within two to three hours. Slower recovery should initiate transfer to a medical facility and a careful search for missed diagnoses.10...
Diagnosis
- The diagnosis of heat stroke is almost always made by the patient's symptoms, exposure to hot surroundings, and taking the core body temperature (rectal temperature). Other tests are usually done to check electrolyte levels, urine studies for renal damage, liver damage, and rhabdomyolysis (muscle breakdown). Tests such as chest X-ray, CT, or MRI may be ordered to search for additio…
- Heatstroke is a much more severe entity than heat exhaustion. The diagnosis of heatstroke rests on two critical factors: hyperthermia and central nervous system dysfunction. Heat-stroke is a medical emergency, and mortality can approach 10 percent.3 It is essential that clinicians recognize the signs of heatstroke and initiate cooling rapidly. When appropriate treatment is pro…
Classification
- Heat-related illnesses typically are categorized as heat exhaustion or heatstroke. Heatstroke is divided further into classic and exertional forms. Classic heatstroke is caused by environmental exposure and results in core hyperthermia above 40°C (104°F). This condition primarily occurs in the elderly and those with chronic illness. Classic heatstroke can develop slowly over several da…
Assessment
- Two indices are available to aid physicians in evaluating heat danger. The National Weather Service has produced a Heat Index chart that can be accessed online athttp://www.crh.noaa.gov/pub/heat.htm.
