Decreased Body Temperature01:29

Decreased Body Temperature

727
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

787
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.

Assessing Body Temperature - Temporal Artery01:19

Assessing Body Temperature - Temporal Artery

699
Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.  
Step 3: Assess the patient's...

Increased Body Temperature01:25

Increased Body Temperature

2.8K
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...

Assessing Body Temperature - Rectal01:27

Assessing Body Temperature - Rectal

6.9K
Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...

Summary
This summary is machine-generated.

Active temperature management shows promise in critically ill patients, particularly therapeutic hypothermia for cardiac arrest survivors. However, evidence for other critical illnesses and antipyretic therapy remains inconclusive, necessitating further research.

Area of Science:

  • Critical Care Medicine
  • Thermoregulation
  • Clinical Trials

Background:

  • Abnormal body temperature is a significant indicator of disease in critically ill patients.
  • Modulating body temperature presents an attractive therapeutic target for various critical conditions.

Purpose of the Study:

  • To synthesize and critically evaluate the existing evidence on active temperature management in critically ill individuals.
  • To assess the efficacy of targeted temperature management and antipyretic therapies across different critical illnesses.

Main Methods:

  • A comprehensive literature search was conducted in MEDLINE, supplemented by bibliography searches.
  • Included studies encompassed systematic reviews, meta-analyses, randomized controlled trials, observational studies, and nonhuman data.
  • Focus was placed on recent randomized controlled trial evidence for cardiac arrest, stroke, traumatic brain injury, and sepsis.

Main Results:

  • Therapeutic hypothermia demonstrates the strongest evidence in comatose survivors of cardiac arrest, with target temperatures between 33°C and 37.5°C considered reasonable.
  • Targeted temperature management has not shown significant benefits in large trials for acute stroke, traumatic brain injury, or sepsis.
  • Pharmacologic antipyretic therapy trials have not improved outcomes, though fever treatment is recommended in stroke and TBI based on observational data.

Conclusions:

  • Body temperature management is a frequently employed strategy in critical care, with ongoing research to refine targets and timing.
  • While therapeutic hypothermia shows promise for specific conditions like post-cardiac arrest, its application in other critical illnesses requires further investigation.
  • Additional studies are essential to clarify optimal temperature management strategies and therapeutic pathways for diverse critical conditions.
