Decreased Body Temperature01:29

Decreased Body Temperature

1.0K
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Methods of reducing fever

1.2K
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Increased Body Temperature

6.4K
A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Homeostatic Imbalances in Body Temperature01:19

Homeostatic Imbalances in Body Temperature

4.3K
Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

Thermoregulation01:26

Thermoregulation

2.3K
The human body has a sophisticated thermoregulation system that employs negative feedback mechanisms to maintain an optimal core temperature. When the core temperature drops, peripheral and central thermoreceptors send signals to the hypothalamus, activating the heat-promoting center. This center triggers several responses aimed at increasing the core temperature. First, vasoconstriction reduces the flow of warm blood from internal organs to the skin so that the heat is not lost from the skin,...

Area of Science:

  • Emergency Medicine
  • Critical Care
  • Geriatrics

Background:

  • Accidental hypothermia is a complex, life-threatening emergency with limited standardized treatment guidelines.
  • Understanding its morbidity, mortality, and influencing factors is crucial for improving patient outcomes.

Purpose of the Study:

  • To investigate hypothermia cases in Portugal, a temperate climate.
  • To analyze rewarming treatments, mortality factors, and complications in hypothermic patients.
  • To address the knowledge gap in hypothermia management.

Main Methods:

  • Retrospective study of 62 patients with body temperatures below 35°C.
  • Data collected from January 2008 to December 2020 at a Portuguese Emergency Department.
  • Analysis included patient demographics, hypothermia causes, treatments, and outcomes.

Main Results:

  • The cohort had a high average age (82 years) and a significant mortality rate (33.9%).
  • Clinical infection, predominantly respiratory, was present in over half of the patients.
  • No single rewarming method demonstrated superior efficacy; rhabdomyolysis was a noted complication.

Conclusions:

  • Accidental hypothermia necessitates further research and multicenter data for evidence-based strategies.
  • Clinical infection is a critical determinant of mortality in hypothermia.
  • Prompt identification and management of infections are vital during hypothermic episodes.
