Trauma is the leading cause of death in young adults, bleeding and infection are major concomitant problems. We test the hypothesis that fast, perioperative warming with an endovascular catheter versus forced air warming may improve patient outcome (primary outcome: combined perioperative morbidity, secondary outcome: bleeding, infection).

Detailed Description:

Trauma is the leading cause of death in young adults and a major cause of morbidity and mortality at all ages. The acute problem is often uncontrollable bleeding. Subsequently, infection becomes a leading cause of morbidity. Polytrauma patients are at high risk for accidental hypothermia. Mild perioperative hypothermia causes a coagulopathy that significantly augments blood loss and increases allogeneic transfusion requirements. Hypothermia also impairs numerous immune functions - even slight decreases in core temperature triple the risk of surgical wound infection.

Endovascular temperature management system Alsius® (ICY, Alsius Corporation: Irvine,California,USA) has been approved in Europe and United States for the past 10 years and has been used in thousands of patients mainly for the indication of therapeutic cooling and subsequently rewarming of patients. A major potential advantage of this system is that heat is directly added to the thermal core, thus bypassing the heat sink and insulating effects of peripheral tissues. The efficacy of this system is sufficient to allow rapid rewarming in hypothermic trauma victims, even those undergoing major surgery. We therefore propose to test the hypothesis that polytrauma patients rewarmed with the Alsius® system will have better patient outcome (combined perioperative morbidity) than those warmed conventionally with forced-air.
