Summary
Transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) helps maintain body temperature during non-intubated video-assisted thoracic surgery (NIVATS). This method shows less intraoperative temperature decrease compared to oxygen masks, particularly in older patients.
Area of Science:
- Anesthesiology
- Thoracic Surgery
- Critical Care Medicine
Background:
- Non-intubated video-assisted thoracic surgery (NIVATS) utilizes advanced ventilation techniques.
- Transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) is increasingly used for improved oxygenation in NIVATS.
- The impact of THRIVE on intraoperative temperature regulation remains underexplored.
Purpose of the Study:
- To investigate the effect of THRIVE compared to oxygen masks on intraoperative temperature decrease in NIVATS patients.
- To identify factors associated with intraoperative temperature changes during NIVATS.
Main Methods:
- Retrospective analysis of 256 adult patients undergoing NIVATS.
- Comparison of pre- and postoperative tympanic temperatures between THRIVE and oxygen mask groups.
- Multiple linear regression to identify predictors of intraoperative temperature decrease.
Main Results:
- Patients using THRIVE exhibited significantly higher postoperative temperatures than those using oxygen masks.
- The THRIVE group showed significantly less intraoperative temperature decrease (0.20°C vs 0.43°C).
- Advanced age was associated with greater temperature decrease, while THRIVE use was associated with less decrease.
Conclusions:
- THRIVE is effective in preventing intraoperative temperature decrease during NIVATS.
- THRIVE offers a significant advantage in maintaining core body temperature compared to oxygen masks.
- The benefits of THRIVE in temperature regulation are particularly notable in elderly patients.

A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...

01:29Administering Oxygen by Nasal Cannula
3.1K
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.

The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.

6.8K
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...
