 Previous research has shown that pre-warming patients prior to surgery can help reduce the risk of inadvertent perioperative hypothermia. This study found that when patients were pre-warmed for 10 minutes before anesthesia induction and throughout the surgical procedure, the rate of intraoperative hypothermia was significantly lower than when patients were not pre-warmed. Additionally, post-operative shivering was less common among patients who had been pre-warmed. These results suggest that pre-warming patients prior to surgery may be an effective way to reduce the risk of perioperative hypothermia.
