Increased Body Temperature01:25

Increased Body Temperature

647
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 Temperature

114
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...

Types of Fever01:25

Types of Fever

355
Fever can be triggered by several factors, including infections, nervous system disorders, certain cancers, blood diseases like leukemia, embolism, thrombosis, heatstroke, dehydration, surgical trauma, crushing injuries, and allergic reactions.
Here are the different types of fever:

Decreased Body Temperature01:29

Decreased Body Temperature

602
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 fever01:22

Methods of reducing fever

649
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.

Summary
This summary is machine-generated.

Malignant hyperthermia (MH) is a severe reaction to anesthesia, requiring prompt management with dantrolene and cooling. Early diagnosis and specialized follow-up are crucial for patient safety and future anesthetic care.

Area of Science:

  • Critical Care Medicine
  • Anesthesiology
  • Pharmacology

Background:

  • Malignant hyperthermia (MH) is a rare, life-threatening pharmacogenetic disorder.
  • It is triggered by volatile anesthetics and succinylcholine in susceptible individuals.
  • MH presents with hyperthermia, hypercarbia, and muscle rigidity.

Purpose of the Study:

  • To review the clinical epidemiology of MH in critically ill patients.
  • To summarize current management strategies for MH.
  • To highlight the importance of recognizing and managing MH in intensive care units (ICUs).

Main Methods:

  • A narrative expert review was conducted.
  • Medline searches identified relevant articles on MH epidemiology, pathophysiology, and management.
  • Guidelines from key MH organizations were incorporated.

Main Results:

  • MH is a severe reaction with rapid onset, characterized by temperature rise, hypercarbia, and rigidity.
  • Complications include coagulopathy, rhabdomyolysis, and acute kidney injury.
  • Management involves dantrolene, active cooling, and hyperventilation, requiring a multidisciplinary approach.

Conclusions:

  • Increased use of volatile anesthetics in ICUs necessitates better MH education.
  • Enhanced diagnosis and management are vital for patient safety and sedation care.
  • Suspected MH requires specialized testing and counseling for patients and families.
