Abstract Introduction: Normal body temperature is generally considered to be 37.0°C (98.6°F). In healthy individuals, this temperature varies by 0.5 to 1.0°C, according to circadian rhythm and menstrual cycle. With heavy exercise, temperature can rise by 2 to 3°C. Whereas many biological processes can alter body temperature, a variety of environmental forces in an ICU can also alter temperature, such as specialized mattresses, hot lights, air conditioning, cardiopulmonary bypass, peritoneal lavage, dialysis, and continuous hemofiltration. Aim of the Essay: The aim of the essay is to throw a light on heat regulation in normal body and hyperthermia in ICU patients concerning its difference from fever, causes, pathophysiology, diagnosis, prevention and its management in ICU patients. Summary: Thermoregulation is the ability of an organism to keep its body temperature within certain limits, even when the surrounding temperature is very different. If the body is unable to maintain a normal temperature and its temperature significantly increases above normal, a condition known as hyperthermia ensues. Conclusion: To treat Hyperthermia, the underlying cause must be removed. Hyperthermia at or above 40°C is a life-threatening medical emergency that requires immediate treatment with adequate and efficient cooling measures. Hyperthermia that results from drug exposure requires prompt cessation of that drug, and occasionally the use of other drugs as counter measures |
