Assessing Body Temperature - Temporal Artery01:19

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...

Assessing Body Temperature - Rectal01:27

Assessing Body Temperature - Rectal

12.9K
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...

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...

Temperature Measurement Sites01:14

Temperature Measurement Sites

3.6K
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...

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...

Summary
This summary is machine-generated.

Temperature variability after traumatic brain injury is a modifiable risk factor. High temperature variability in the first 48 hours is linked to poorer outcomes in patients not receiving therapeutic hypothermia.

Area of Science:

  • Neuroscience
  • Critical Care Medicine
  • Clinical Trials

Background:

  • Therapeutic hypothermia in traumatic brain injury (TBI) patients with elevated intracranial pressure (ICP) has shown deleterious effects.
  • Understanding modifiable risk factors for poor outcomes in TBI is crucial for improving patient management.

Purpose of the Study:

  • To investigate if temperature variability within the first 48 hours and 7 days post-randomization are modifiable risk factors for poorer outcomes in TBI patients.
  • To analyze the impact of temperature variability on outcomes in the context of the Eurotherm3235 trial.

Main Methods:

  • A multicenter randomized controlled trial (Eurotherm3235) involving patients with TBI.
  • Stratification of subjects into tertiles based on core temperature variability using the mean moving range (mr) within 48 hours and 7 days post-randomization.
  • Ordinal logistic regression analysis to estimate the effect of temperature variability on the collapsed Glasgow Outcome Scale-Extended (cGOS-E) at 6 months, adjusted for covariates and treatment.

Main Results:

  • High temperature variability within the first 48 hours was associated with poorer cGOS-E outcomes.
  • This association remained significant in the control arm (standard care only) but not in the therapeutic hypothermia arm.
  • No significant effect of temperature variability was observed within 7 days in either treatment group.

Conclusions:

  • Temperature variability, particularly within the first 48 hours, may be a significant predictor of outcomes in TBI patients when normothermia is targeted.
  • These findings suggest that controlling temperature fluctuations could be a potential therapeutic target in TBI management.
