Temperature maintenance in infants undergoing anaesthesia and surgery
Anaesthesia and Intensive Care
|August 1, 1985
Summary
Infants undergoing anesthesia lose less heat when using a warming blanket, humidifier, and overhead heater together. Overhead heaters are especially beneficial during long neurosurgery preparations, reducing infant heat loss.
Area of Science:
- Pediatric Anesthesiology
- Neonatal Thermoregulation
Background:
- Maintaining normothermia in infants during anesthesia is critical.
- Infants are susceptible to significant heat loss due to their high surface area to volume ratio.
Purpose of the Study:
- To compare the effectiveness of different warming methods on reducing heat loss in infants during anesthesia.
- To evaluate the combined effect of a warming blanket, humidifier, and overhead heater versus a warming blanket alone.
Main Methods:
- A study was conducted on infants under six months of age.
- Comparison of heat loss with a warming blanket alone versus a combination of warming blanket, humidifier, and overhead heater.
Main Results:
- The combination of a warming blanket, humidifier, and overhead heater resulted in significantly less heat loss compared to the warming blanket alone.
- Overhead heaters demonstrated particular benefit during prolonged preparation for neurosurgery.
Conclusions:
- Combining warming blanket, humidifier, and overhead heater is superior in preventing heat loss in infants during anesthesia.
- Overhead heaters are recommended during anesthesia induction in infants, especially for lengthy procedures like neurosurgery.
