Summary
Forced-air warming devices are effective for preventing perioperative hypothermia, a risk factor for surgical site infections. Current evidence does not support claims that these devices cause infections in total joint arthroplasty patients.
Area of Science:
- Medical Devices
- Infection Control
- Patient Safety
Background:
- Forced-air warmers have been utilized for over two decades to manage perioperative hypothermia.
- Hypothermia is a known risk factor for surgical site infections (SSIs).
Discussion:
- Concerns have been raised regarding the potential role of forced-air warmers in causing SSIs, particularly in total joint arthroplasty.
- A competing device manufacturer has disseminated information to clinicians suggesting risks associated with forced-air warmer use in these procedures.
- Three published reviews have evaluated this issue, with none condemning the use of forced-air warmers, even in total joint arthroplasty.
Key Insights:
- Existing peer-reviewed literature does not substantiate claims that forced-air warmers contribute to surgical site infections.
- Clinicians should critically evaluate information regarding medical devices, prioritizing evidence from peer-reviewed sources.
- The safety and efficacy of forced-air warmers in preventing hypothermia during surgery remain supported by current evidence.
Outlook:
- Further independent research may be warranted to address specific manufacturer claims.
- Continued vigilance and adherence to evidence-based practices are crucial for patient safety.
- Promoting critical appraisal of information sources is essential for informed clinical decision-making.

Heat capacity is the ratio of heat absorbed by the substance corresponding to its temperature change. It is also called thermal capacity and the SI unit of heat capacity is J/K. Whereas, specific heat capacity is defined as the amount of heat necessary to change the temperature of 1 kg of a substance by 1 K and is also called massic heat capacity. Its SI unit is J/kg⋅K.

For a system that undergoes a thermodynamic process at a constant volume condition, the heat absorbed is used only to increase the system's internal energy and not for doing any kind of work. While for a system undergoing a thermodynamic process under a constant pressure condition, the amount of heat absorbed is used not only for increasing the internal energy (as a function of temperature) but also for doing some work. The molar heat capacity is the amount of heat required to increase the...

The number of independent ways a gas molecule can move along straight line, rotate, and vibrate is called its degrees of freedom. Supposing d represents the number of degrees of freedom of an ideal gas, the molar heat capacity at constant volume of an ideal gas in terms of d is

64.5K
The volume occupied by one mole of a substance is its molar volume. The ideal gas law, PV = nRT, suggests that the volume of a given quantity of gas and the number of moles in a given volume of gas vary with changes in pressure and temperature. At standard temperature and pressure, or STP (273.15 K and 1 atm), one mole of an ideal gas (regardless of its identity) has a volume of about 22.4 L — this is referred to as the standard molar volume.

01:18Adiabatic Processes for an Ideal Gas
4.4K
When an ideal gas is compressed adiabatically, that is, without adding heat, work is done on it, and its temperature increases. In an adiabatic expansion, the gas does work, and its temperature drops. Adiabatic compressions actually occur in the cylinders of a car, where the compressions of the gas-air mixture take place so quickly that there is no time for the mixture to exchange heat with its environment. Nevertheless, because work is done on the mixture during the compression, its...

Heat is a type of energy transfer that is caused by a temperature difference, and it can change the temperature of an object. Since heat is a form of energy, its SI unit is the joule (J). Another common unit of energy often used for heat is the calorie (cal), which is defined as the energy needed to change the temperature of 1 g of water by 1 °C, specifically between 14.5 °C and 15.5 °C, since the energy needed shows a slight temperature dependence. Another commonly used unit is...
