About
Mechanical respiration during general anesthesia causes cold and dry gases to reach the lower airway, reduce the function of the airway mucosa, and cause accumulation of secretions. Inhaled dry gas is one of the causes of hypothermia during general anesthesia. To overcome this, the warm-humidifying breathing circuit uses warm, moisture-preserving gas to promote mucus mobility of the airway mucosal ciliate cells and prevents cold gases from evaporating from the mucosal surfaces which results lowering body temperature. We aimed to investigate the effect of newly developed Sohum warm humidifying respiration circuit (SH501) on the prevention of core body temperature reduction during surgery and systemic inflammation reaction.
