Decreased Body Temperature01:29

Decreased Body Temperature

651
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

701
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 Temperature01:25

Increased Body Temperature

712
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

155
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...

Temperature Measurement Sites01:14

Temperature Measurement Sites

1.8K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Area of Science:

  • Anesthesiology
  • Perioperative Medicine
  • Patient Safety

Background:

  • Maintaining normothermia (core body temperature > 36°C) is vital for patient safety and recovery, as recommended by the World Health Organization.
  • Inadvertent perioperative hypothermia (IPH) is multifactorial, stemming from preoperative exposure, low operating room temperatures, and lack of warming devices.
  • Anesthesia blunts the body's natural response to cold, increasing susceptibility to hypothermia.

Purpose of the Study:

  • To highlight the importance of temperature regulation in the perioperative period.
  • To discuss the causes and consequences of inadvertent perioperative hypothermia (IPH).
  • To emphasize strategies for preventing IPH.

Main Methods:

  • Review of factors contributing to IPH.
  • Discussion of physiological responses to hypothermia.
  • Analysis of complications associated with hypothermia.

Main Results:

  • IPH is caused by various factors including environmental conditions, patient exposure, and anesthetic agents.
  • Hypothermia in the postoperative period is linked to increased surgical site infections, mortality, and prolonged hospital stays.
  • Proactive identification of risk factors and implementation of warming strategies are key to prevention.

Conclusions:

  • Effective temperature management during surgery is essential for minimizing patient morbidity and mortality.
  • Preventing inadvertent perioperative hypothermia requires a comprehensive approach addressing preoperative, intraoperative, and postoperative factors.
  • Monitoring patient temperature and utilizing warming devices are critical interventions.
