Heat fatigue, heat syncope (sudden dizziness after prolonged exposure to the heat), heat cramps, heat exhaustion and heat stroke are commonly known forms of hyperthermia. Risk for these conditions can increase with the combination of outside temperature, general health and individual lifestyle.
What causes hyperthermia and what are the symptoms?
Hyperthermia occurs when the body can no longer release enough of its heat to maintain a normal temperature. The body has different coping mechanisms to get rid of excess body heat, largely breathing, sweating, and increasing blood flow to the surface of the skin.
What's the difference between hypothermia and hyperthermia?
Hypothermia and hyperthermia are two extreme, but equally concerning, states of temperature loss or gain. Hypothermia occurs when you lose more heat than your body can produce and you feel very cold. Hyperthermia occurs when your body produces more heat than it can lose.

Why does sweating cause dehydration?
As the body attempts to cool itself by sweating , the sweat takes with it water and crucial salts called electrolytes, causing dehydration. Mild dehydration tends to cause minor symptoms, such as headache and muscle cramps. Severe dehydration, however, can strip the body of its ability to cool. Without treatment, this can result in dangerously high ...
What happens when the body can no longer release enough heat to maintain a normal temperature?
Hyperthermia occurs when the body can no longer release enough of its heat to maintain a normal temperature. The body has different coping mechanisms to get rid of excess body heat, largely breathing, sweating, and increasing blood flow to the surface of the skin.
What is it called when your body is too hot?
Hyperthermia is a group of conditions where the body becomes too hot and cannot regulate its temperature. The symptoms of hyperthermia depend on the stage it has reached or how much the body is overheated. Symptoms of overheating may develop very quickly or over the course of hours or days.
How to get your body temperature back to normal?
taking a cool shower or bath. using cool, wet cloths on the skin. Once in the hospital, doctors may give intravenous fluids containing electrolytes and possibly chilled fluids.

Drugs that do not trigger malignant hyperthermia may be used as part of your anesthesia.
What are the symptoms of heat stroke?
This happens when the body is no longer able to regulate its internal temperature; this is a medical emergency. The body temperature may be over 105 F, a level that damages the brain and other organs. Other symptoms include muscle cramps, fatigue, dizziness, headache, nausea, vomiting, and weakness. The heart rate may be elevated, and the skin is reddened. The skin may be moist if sweating is still occurring, or it may be dry if sweating has stopped. Confusion and mental changes may develop, and seizures can occur with brain damage. Ultimately, coma and death may ensue.

How to lower body temperature?
Antipyretic medications lower body temperature by blocking the synthesis of prostaglandins that act in the hypothalamus. Ready oxygen therapy for extreme cases. Hyperthermia increases the metabolic demand for oxygen. Provide chlorpromazine (Thorazine) and diazepam (Valium) when excessive shivering occurs.
How does hyperthermia differ from fever?
Hyperthermia differs from fever in that it is characterized by an uncontrolled increase in body temperature that exceeds the body’s ability to lose heat. The setting of the hypothalamic thermoregulatory center is unchanged. In contrast to fever in infections, hyperthermia does not involve pyrogenic molecules.
Why do people get hyperthermia?
Common cases of hyperthermia result from the combined effects of activity and salt and water deprivation in a hot environment , such as when athletes perform in extremely hot weather or when older adults avoid the use of air conditioning because of expense.
How to regulate temperature of a patient?
Room temperature may be accustomed to near normal body temperature and blankets and linens may be adjusted as indicated to regulate temperature of the patient. Eliminate excess clothing and covers. Exposing skin to room air decreases warmth and increases evaporative cooling. Give antipyretic medications as prescribed.
What should be measured to monitor fluid status?
Extremes of age or weight increase the risk for the inability to control body temperature. Monitor fluid intake and urine output. If the patient is unconscious , central venous pressure or pulmonary artery pressure should be measured to monitor fluid status. Fluid resuscitation may be required to correct dehydration.
How to tell if you have a MH?
Clinical symptoms of MH are highly variable, and range from abortive courses with mild or moderate symptoms to fulminant MH crises with severe skeletal muscle hypermetabolism and rhabdomyolysis. Excessive CO2production presenting with an increase in end tidal CO2concentration or hyperventilation while breathing spontaneously is a sensitive and specific early sign of imminent MH. An abrupt rise in end tidal CO2may occur simultaneously with administration of succinylcholine.7,54Further early symptoms of an MH crisis may include tachycardia, supraventricular or ventricular arrhythmia, and isolated masseter spasm or generalized muscular rigidity. 50–80% of patients develop arrythmia or muscular reactions.53Nonspecific sinus tachycardia might be misinterpreted as inadequate anesthesia, which often delays the diagnosis of MH. Distinctive cyanosis indicating increased oxygen consumption may occur later in the course of an MH episode. A rapid increase in temperature (to >38.8°C) is a relatively late sign. However, a rapid increase of >1°C in 15 minutes is diagnostically more relevant than the peak temperature.22,55In some cases, there are no relevant changes in body temperature, particularly if adequate treatment is started early.56,57Arterial blood gas analyses reveal a combination of respiratory and metabolic acidosis with negative base excess, lactemia, hypercapnia, and hypoxemia. Fulminant MH crisis usually presents with paCO2values >60 mmHg and a base excess of >8 mVal/L. As the MH episode progresses, rhabdomyolysis leads to hyperkalemia, increased creatine phosphokinase, and myoglobinemia, and might result in acute renal failure. The end stage of a fulminant MH crisis is characterized by multiorgan failure and circulatory collapse (Table 1).7
Is malignant hyperthermia inherited?
Malignant hyperthermia is a potentially lethal inherited disorder characterized by disturbance of calcium homeostasis in skeletal muscle. Volatile anesthetics and/or the depolarizing muscle relaxant succinylcholine may induce this hypermetabolic muscular syndrome due to uncontrolled sarcoplasmic calcium release via functionally altered calcium release receptors, resulting in hypoxemia, hypercapnia, tachycardia, muscular rigidity, acidosis, hyperkalemia, and hyperthermia in susceptible individuals. Since the clinical presentation of malignant hyperthermia is highly variable, survival of affected patients depends largely on early recognition of the symptoms characteristic of malignant hyperthermia, and immediate action on the part of the attending anesthesiologist. Clinical symptoms of malignant hyperthermia, diagnostic criteria, and current therapeutic guidelines, as well as adequate management of anesthesia in patients susceptible to malignant hyperthermia, are discussed in this review.
What is the best treatment for malignant hyperthermia?
The symptoms of malignant hyperthermia must be treated immediately. A drug, usually dantrolene (Dantrium®), is given to relieve symptoms quickly and to stop the excess calcium from getting into the muscles.
How does hyperthermia affect the body?
If it is not treated, malignant hyperthermia can lead to the failure of several organs, internal bleeding, cardiac arrest and possibly death.
What is the prognosis for patients who are at risk for malignant hyperthermia?
What is the prognosis (outlook) for patients who are at risk for malignant hyperthermia? If the patient has an abnormal reaction to anesthesia and the symptoms are treated immediately, the prognosis is good. If malignant hyperthermia is not treated, serious medical complications, up to and include death, can occur.
How to know if you are under anesthesia?
The patient may not have any health issues until the symptoms actually occur when he or she receives anesthesia. Symptoms come on quickly, and can include: 1 Rapidly increasing body temperature, sometimes to more than 105 degrees F (40.6 degrees C) 2 Muscle stiffness. The muscles react to the anesthesia by releasing calcium that is normally stored within the muscle cells. Excess calcium causes the muscles to shrink and stiffen. 3 Rapid, and possibly irregular, heartbeat
What is the chance of inheriting malignant hyperthermia?
If one parent has the gene for the syndrome, the baby has a 50 percent chance of inheriting it. Most cases occur in people in their early 20s. Some studies show that men are more at risk than women to develop malignant hyperthermia.
What should a patient tell the doctor about his or her family history before surgery?
The patient should tell the doctor and other caregivers about his or her family history before any surgeries or medical procedures. The surgeon and anesthesiologist can then plan to use other anesthesia drugs, and can be on the lookout for signs of malignant hyperthermia once the surgery begins.
