Factors Affecting Body Temperature01:28

Factors Affecting Body Temperature

9.5K
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

1.1K
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...

Assessing Body Temperature - Temporal Artery

1.3K
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

7.5K
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 - Axilla

1.5K
Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

Homeostatic Imbalances in Body Temperature01:19

Homeostatic Imbalances in Body Temperature

4.2K
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...

Summary

Elevated body temperature after stroke is common and linked to stroke severity. Factors like stroke severity, female gender, and infection predict temperature increases within 48 hours.

Area of Science:

  • Neurology
  • Internal Medicine
  • Critical Care Medicine

Background:

  • Elevated body temperature post-stroke is linked to poor outcomes.
  • Predictors of early post-stroke temperature elevation require investigation.

Purpose of the Study:

  • To identify factors predicting temperature elevation within 48 hours of stroke onset.
  • To test if stroke severity and stroke type (hemorrhagic vs. ischemic) influence temperature elevation.

Main Methods:

  • Retrospective review of 400 stroke patient medical records.
  • Multiple linear regression analysis to identify predictors of elevated body temperature.

Main Results:

  • Stroke severity (NIHSS), female gender, swallowing difficulties, intubation, antipyretic treatment, and infection/high C-reactive protein predicted higher peak body temperature.
  • Tympanic/non-rectal temperature readings were associated with lower peak temperatures.
  • Contrary to hypothesis, intracerebral hemorrhage did not result in higher peak temperatures than ischemic stroke.

Conclusions:

  • Post-stroke temperature elevation within 48 hours is frequent and partially predictable at admission.
  • Strong association between temperature elevation and stroke severity may explain negative outcomes.
  • Findings emphasize the importance of monitoring temperature in stroke patients.
