Equipments Used to Measure Body Temperature

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,...

Assessing Body Temperature - Temporal Artery

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...

Area of Science:

Medical imaging
Surgical anatomy
Reconstructive surgery

Background:

Perforator flaps are vital in reconstructive surgery, necessitating precise vascular anatomy navigation.
Established imaging techniques include Doppler, CT, and MRA, but thermal imaging shows promise.
This study evaluates thermal imaging for perforator identification across multiple body regions.

Purpose of the Study:

To assess the efficacy of thermal imaging in identifying cutaneous perforators.
To evaluate the anatomical distribution of perforators in the abdomen, sacrum, and anterolateral thighs.
To compare thermal imaging findings with hand-held Doppler confirmation.

Main Methods:

Thermal imaging was used to assess perforators in 20 volunteers across the abdomen, sacrum, and anterolateral thighs.
Surface landmarks were marked, and thermal imaging findings (hotspots) were immediately verified with hand-held Doppler.
A color digital photograph documented each region for analysis.

Main Results:

Thermal imaging detected 757 hotspots, with 97% confirmed by hand-held Doppler.
An average of 4.6 perforators were found within 5 cm of abdominal landmarks, 1.3 within 2.5 cm.
Sacral and thigh regions also showed perforator distribution relative to anatomical landmarks.

Conclusions:

Thermal imaging offers a rapid and straightforward approach to cutaneous perforator assessment.
It serves as a valuable adjunct to existing imaging modalities for perforator mapping.
Further research is recommended to define its optimal role in surgical planning.
