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...
Equipments Used to Measure Body Temperature01:13

Equipments Used to Measure Body Temperature

Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
Assessing Body Temperature - Temporal Artery01:19

Assessing Body Temperature - Temporal Artery

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 forehead...

Summary

Temperature adjustment for thromboelastography (TEG) during hypothermia has minimal clinical importance. The inherent low reproducibility of TEG makes temperature correction unnecessary for routine use in critical care settings.

Area of Science:

  • Critical Care Medicine
  • Hematology
  • Clinical Pathology

Background:

  • Hypothermia significantly impacts thromboelastography (TEG) results.
  • TEG measurements are known for their generally low reproducibility.

Purpose of the Study:

  • To assess the necessity of adjusting TEG for in-vivo temperature in hypothermic patients.
  • To determine if temperature adjustment is clinically relevant given TEG's inherent variability.

Main Methods:

  • Prospective observational study involving 30 survivors of cardiopulmonary resuscitation.
  • TEG analysis (Kaolin-Heparinase and Rapid-TEG) performed at 12-hour intervals over 36 hours.
  • Comparison of temperature-adjusted versus non-adjusted TEG parameters during hypothermia and normothermia.

Main Results:

  • Temperature adjustment showed a greater bias in clot formation variables during hypothermia compared to normothermia.
  • Bias in clot strength variables was not affected by temperature adjustment.
  • Wide limits of agreement for clot formation variables were observed, irrespective of temperature adjustment.

Conclusions:

  • While temperature adjustment for TEG in hypothermia results in minor systematic bias, its clinical significance is low.
  • The inherent imprecision of TEG measurements outweighs the benefit of temperature adjustment in routine clinical practice.
  • Performing TEG at in-vivo temperature during hypothermia is not deemed necessary.
