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...
Types of Fever01:25

Types of Fever

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:
Factors Affecting Body Temperature01:28

Factors Affecting Body Temperature

As a nurse, it is vital to understand the factors affecting body temperature to monitor variations and effectively evaluate deviations from regular.
Factors may  include:
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.

Area of Science:

  • Anesthesiology and Critical Care Medicine

Background:

  • Limited literature exists on perioperative fever and hyperthermia sources.
  • Anecdotal reports and small case series dominate the current understanding.

Purpose of the Study:

  • To provide a comprehensive differential diagnosis for perioperative fever and hyperthermia.
  • To assist anesthesiologists, intensivists, and emergency physicians in accurate diagnosis and treatment.
  • To expand awareness of common and uncommon fever sources relevant to surgical patients.

Main Methods:

  • A thorough literature search was conducted.
  • Identified common and uncommon sources of fever and hyperthermia were compiled.

Main Results:

  • Numerous potential causes of perioperative fever were identified.
  • Several sources are highly relevant to anesthesiology practice.
  • Some identified causes represent rare or obscure clinical scenarios.

Conclusions:

  • Enhanced understanding of perioperative fever differentials improves diagnostic accuracy.
  • Appropriate treatment selection is facilitated by a broad differential diagnosis.
  • This review serves as a guide for clinicians managing perioperative fever.
