Decreased Body Temperature01:29

Decreased Body Temperature

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 sustained extreme cold exposure, and severe...
Methods of reducing fever01:22

Methods of reducing fever

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.
Pharmacological Methods of Reducing Fever:
Increased Body Temperature01:25

Increased Body Temperature

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 response to an infection or illness.
Homeostatic Imbalances in Body Temperature01:19

Homeostatic Imbalances in Body Temperature

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

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,...

This summary is machine-generated.

Therapeutic hypothermia is recommended for comatose adults after cardiac arrest, with specific guidelines for different patient groups. This treatment involves cooling patients to 32-34°C for 12-24 hours to improve outcomes.

Area of Science:

  • Cardiology
  • Neurology
  • Critical Care Medicine

Context:

  • International Liaison Committee on Resuscitation (ILCOR) guidelines.
  • Post-cardiac arrest care protocols.
  • Management of comatose patients with return of spontaneous circulation.

Purpose:

  • To outline ILCOR recommendations for therapeutic hypothermia.
  • To define patient populations who may benefit from induced hypothermia.
  • To specify target temperatures and durations for hypothermia treatment.

Summary:

  • Comatose adults with out-of-hospital VF cardiac arrest should be cooled to 32-34°C for 12-24 hours.
  • Therapeutic hypothermia may benefit patients with nonshockable rhythms, in-hospital arrests, adolescents, and infants/children.
  • Newborns with hypoxic-ischemic encephalopathy should be offered therapeutic hypothermia.

Impact:

  • Standardizes hypothermia treatment protocols globally.
  • Potentially improves neurological outcomes and survival rates post-cardiac arrest.
  • Guides clinical decision-making in critical care settings.
