Summary
Cold challenges, particularly airflow cooling, are more effective than warm challenges for preoperative perforator mapping in reconstructive surgery. This method improves flap perfusion success and correlation with other imaging techniques.
Area of Science:
- Plastic Surgery
- Medical Imaging
Background:
- Dynamic infrared thermography is crucial for reconstructive surgery.
- Preoperative perforator mapping aids surgical planning and success.
Purpose of the Study:
- To investigate thermal challenge approaches (cold and warm) in dynamic infrared thermography.
- To determine the impact of these challenges on preoperative perforator mapping success.
Main Methods:
- Systematic review following PRISMA guidelines.
- Literature search across Ovid Medline, Embase, PubMed, and Cochrane databases.
- Qualitative analysis of 13 extracted articles.
Main Results:
- Cold challenges (airflow, direct contact, evaporation) showed high flap perfusion success and correlation.
- Airflow cooling demonstrated effectiveness with minimal patient discomfort.
- Warm challenges had less conclusive results due to limited studies.
Conclusions:
- Cold challenges are superior to no challenge and warm challenges for perforator mapping.
- Airflow cooling is recommended for its effectiveness, uniformity, and patient comfort.
- Further large-scale studies with standardized equipment are needed to confirm findings.

01:13Equipments Used to Measure Body Temperature
1.1K
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,...

01:14Temperature 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...

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...

01:09Thermal Stress
2.5K
If the temperature of an object is changed while it is prevented from expanding or contracting, the object is subjected to stress. The stress is compressive if the object expands in the absence of constraint and tensile if it contracts. This stress resulting from temperature change is known as thermal stress. It can be quite large and can cause damage. To avoid this stress, engineers may design components so they can expand and contract freely. For instance, on highways, gaps are deliberately...
