Insights

This review examines research on tympanic membrane thermometers for children in acute care. It assesses accuracy, comparisons, and influences like patient preference and ear conditions.

Area of Science:

  • Pediatric healthcare
  • Medical device evaluation
  • Clinical thermometry

Background:

  • Tympanic membrane thermometry is increasingly used for pediatric temperature measurement.
  • Concerns exist regarding the accuracy of tympanic membrane thermometers.
  • Research comparing tympanic membrane thermometers with other body site measurements is needed.

Purpose of the Study:

  • To determine the most appropriate, research-based thermometry method for children in acute healthcare settings.
  • To evaluate factors influencing thermometer choice, including patient and nurse preferences, and specific pediatric conditions.

Main Methods:

  • Literature review of research-based evidence on thermometry methods for children.
  • Analysis of factors affecting thermometer selection and accuracy.
  • Consideration of patient preferences and ethical aspects, such as children's rights.

Main Results:

  • The review addresses concerns about tympanic membrane thermometer accuracy.
  • It explores the appropriateness of comparing tympanic membrane temperatures with other sites.
  • Influential factors like age, ear conditions (otitis media, wax, pain, grommets), and preferences are discussed.

Conclusions:

  • Evidence-based recommendations for selecting the most appropriate thermometry method for children in acute care are needed.
  • Further research should address patient preferences and ethical considerations, particularly concerning rectal thermometry and children's rights.

Assessing Body Temperature - Tympanic membrane

Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...
Temperature Measurement Sites01:14

Temperature Measurement Sites

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...

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,...

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.

Assessing Body Temperature - Oral

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...
Assessing Body Temperature - Rectal01:27

Assessing Body Temperature - Rectal

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...
