Assessing Body Temperature - Rectal01:27

Assessing Body Temperature - Rectal

13.7K
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...

Temperature Measurement Sites

3.8K
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...

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...

Equipments Used to Measure Body Temperature

2.0K
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,...

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...

Assessing Body Temperature - Oral

1.8K
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

For exertional heat-stroke (EHS) management, inserting a rectal thermistor 15 cm deep provides the most valid core temperature estimate. This depth minimizes bias compared to shallower insertions, aiding accurate hyperthermia diagnosis.

Area of Science:

  • Sports Medicine
  • Physiology
  • Clinical Thermometry

Background:

  • Evidence-based recommendations for rectal thermistor insertion depth are lacking.
  • Accurate core temperature measurement is crucial for managing exertional heat-stroke (EHS).

Purpose of the Study:

  • To determine the optimal rectal thermistor insertion depth (4 cm, 10 cm, or 15 cm) for valid core temperature estimation.
  • To compare rectal temperature (Trec) validity against esophageal temperature (Teso) under various physiological stressors.

Main Methods:

  • A cross-sectional laboratory study involving 17 participants.
  • Rectal temperatures were measured at 4, 10, and 15 cm depths and compared with esophageal temperature.
  • Measurements were taken during rest, exercise to Teso of 39.5°C, cold-water immersion, and recovery.

Main Results:

  • Rectal thermistor depth significantly affected temperature bias (P = .008).
  • Bias was lowest at 15 cm (0.65°C ± 0.68°C) compared to 4 cm (0.85°C ± 0.78°C).
  • Temperature bias was highest during cold-water immersion (1.72°C ± 0.65°C).

Conclusions:

  • A 15 cm rectal thermistor insertion depth is recommended for the most valid core temperature estimate in suspected EHS.
  • Rectal temperature measurements during exercise show minimal bias, supporting their use in diagnosing hyperthermia.
  • Rectal temperature is a more accurate indicator of pelvic organ temperature during cold-water immersion than esophageal temperature.
