Assessing Body Temperature - Rectal01:27

Assessing Body Temperature - Rectal

16.4K
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...

Equipments Used to Measure Body Temperature

2.1K
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,...

Temperature Measurement Sites

4.2K
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...

Assessing Body Temperature - Oral

2.0K
Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...

Summary
This summary is machine-generated.

Mild induced hypothermia used for neuroprotection affects blood coagulation in cardiac arrest patients. Rotational thromboelastometry (ROTEM) assays show hypothermia prolongs clotting time and decreases clot propagation, while hyperthermia has opposite effects.

Area of Science:

  • Cardiovascular Medicine
  • Hematology
  • Critical Care Medicine

Background:

  • Mild induced hypothermia is a neuroprotective strategy for cardiac arrest survivors.
  • The impact of temperature variations on Rotational Thromboelastometry (ROTEM) assays in these patients remains understudied.

Purpose of the Study:

  • To investigate the temperature-dependent effects of hypothermia and hyperthermia on ROTEM assays (EXTEM, FIBTEM, APTEM) in cardiac arrest patients.
  • To assess how temperature influences key coagulation parameters: clotting time (CT), clot formation time (CFT), α-angle, and maximum clot firmness (MCF).

Main Methods:

  • Ten patients who experienced out-of-hospital cardiac arrest and underwent induced hypothermia were studied.
  • Blood samples were analyzed using ROTEM assays at various temperatures (30°C to 42°C) and compared to 37°C.
  • Statistical analysis used the Wilcoxon matched-pairs signed-rank test.

Main Results:

  • Hypothermia (30°C, 33°C) significantly prolonged CT-EXTEM and CT-APTEM, and markedly prolonged CFT-EXTEM and CFT-APTEM.
  • Hypothermia decreased the α-angle in EXTEM and APTEM assays, indicating reduced clot propagation.
  • Hyperthermia (42°C) shortened CT-EXTEM and CT-APTEM, with opposite effects on the α-angle.
  • Maximum clot firmness (MCF) remained unaffected by temperature changes across all assays.

Conclusions:

  • In vitro hypothermia induces a hypocoagulative state in cardiac arrest patients' blood, characterized by delayed clot initiation and reduced clot propagation.
  • Hyperthermia demonstrates procoagulant effects, while clot firmness is temperature-independent.
  • These findings highlight the critical influence of temperature on coagulation dynamics in post-cardiac arrest care.
