Preoperative fluid management contributes to the prevention of intraoperative hypothermia

Intraoperative hypothermia causes several unfavorable events such as surgical site infection and cardiovascular events. Therefore, during anesthesia, temperature is routinely regulated, mainly by using external heating devices. Recently, oral amino acid intake and intravenous amino acid or fructose infusion have been reported to prevent intraoperative hypothermia during general and regional anesthesia. Diet (nutrient) - induced thermogenesis is considered to help prevent intraoperative hypothermia. Since the Enhanced Recovery After Surgery (ERAS) protocol has been introduced, it has been used in perioperative management in many hospitals. Prevention of intraoperative hypothermia is included in this protocol. According to the protocol, anesthesiologists play an important role in both intraoperative and perioperative management. Management of optimal body temperature by preoperative fluid management alone may be difficult. To this end, preoperative fluid management and nutrient management strategies such as preoperative oral fluid intake and carbohydrate loading have the potential to contribute to the prevention of intraoperative hypothermia.
