About this trial
Hypothermia is a common complication in pediatric anesthesia. Hypothermia will prolong the recovery time of anesthesia, and may also lead to increased oxygen consumption, prolonged blood coagulation time, and affect the metabolism of anesthetic drugs and postoperative immune function. Sevoflurane is the most commonly used inhaled anesthetic in children. This study explored the effect of sevoflurane on the sweat threshold of pediatric patients and analyzed the characteristics of body temperature regulation in children of different ages under anesthesia, which will help to understand the mechanism of body temperature regulation in children under anesthesia, and also provide a scientific basis for clinical anesthesia temperature management.
