Assessing Body Temperature - Rectal01:27

Assessing Body Temperature - Rectal

14.3K
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

3.9K
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

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,...

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

1.9K
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...

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...

Summary

Determining infant time of death using rectal temperature is challenging. Ohno's method and a modified Henssge's method (Modification A) show promise for accurate postmortem interval estimation in infants.

Area of Science:

  • Forensic Science
  • Biophysics
  • Pediatrics

Background:

  • Standard adult methods for estimating time of death from rectal temperature may not be suitable for infants.
  • Accurate postmortem interval estimation in infants is crucial for forensic investigations.

Purpose of the Study:

  • To evaluate the suitability of three established methods for estimating the time of death in infants based on rectal temperature.
  • To compare the accuracy of Ohno's method, Henssge's method, and collinear approximation in infant cases.

Main Methods:

  • Computer simulation using the infinite cylinder model (Ohno's method).
  • Double exponential approximation with parameter determination (Henssge's method).
  • Collinear approximation based on rectal temperature curve extrapolation.
  • Comparison of estimated time of death with the defined death time interval in 20 infant cases.

Main Results:

  • Ohno's method showed reasonable accuracy, with 7 cases within the death time interval and an average deviation of approximately 80 minutes for others.
  • Henssge's method and collinear approximation yielded inferior results compared to Ohno's method.
  • A modified Henssge's method (Modification A), adjusting corrective factors based on body weight, improved accuracy, with 8 cases within the interval and an average deviation of 80 minutes for others.

Conclusions:

  • Ohno's method and Modification A are identified as useful tools for infant postmortem interval estimation.
  • The influence of thermal isolation on infant body cooling may be greater than previously assumed.
  • Estimated time of death in infants should be interpreted with caution, considering other contextual factors.
