Assessing Body Temperature - Rectal01:27

Assessing Body Temperature - Rectal

5.0K
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 Sites01:14

Temperature Measurement Sites

1.8K
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...

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 - Temporal Artery

604
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 - Oral

786
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

Rectal temperature measurement in patients with neutropenia did not increase the risk of bacteremia or in-hospital mortality. This study suggests current recommendations against its use may not be necessary for afebrile neutropenic patients.

Area of Science:

  • Infectious Diseases
  • Clinical Medicine
  • Patient Safety

Background:

  • Current guidelines often advise against rectal thermometry in neutropenic fever patients due to theoretical risks of bacteremia.
  • This recommendation is based on limited evidence, necessitating further investigation.

Purpose of the Study:

  • To evaluate the association between rectal temperature measurement and the risk of bacteremia in afebrile neutropenic patients.
  • To assess the impact of rectal temperature measurement on in-hospital mortality in this patient population.

Main Methods:

  • A retrospective study analyzed adult patients admitted with afebrile neutropenia between 2014-2017.
  • Patients were divided into groups based on whether rectal or oral temperature was measured.
  • Primary outcomes included bacteremia within five days of hospitalization and in-hospital mortality.

Main Results:

  • The study included 40 patients with rectal temperature measurements and 407 with oral measurements.
  • Bacteremia occurred in 10.6% of patients with oral temperatures versus 5.1% with rectal temperatures.
  • Rectal temperature measurement was not significantly associated with bacteremia or in-hospital mortality.

Conclusions:

  • Rectal temperature measurement in afebrile neutropenic patients is not associated with an increased risk of bacteremia.
  • In-hospital mortality rates were similar between patients who underwent rectal versus oral temperature measurement.
  • These findings may inform clinical practice regarding temperature monitoring in neutropenic patients.
