    Abstract
  •   Objective  Elderly patients undergoing knee replacement surgery are at a high risk of intraoperative hypothermia and shivering. Reducing the incidence of hypothermia and shivering in elderly patients undergoing knee replacement is of significant clinical importance. Therefore, this study aimed to explore whether a risk early warning intervention program can effectively reduce the occurrence of intraoperative hypothermia and shivering during operation in elderly patients undergoing knee replacement under general anesthesia.  Methods  A total of 100 elderly patients undergoing general anesthesia in the Second Affiliated Hospital of Wenzhou Medical University from December 2023 to May 2024 were randomly divided into the control group (routine insulation intervention) and the observation group (risk early warning intervention procedure), with 50 cases in each group. Perioperative body temperature, incidence of hypothermia and shivering during operation, stress response markers, and coagulation function were compared between the two groups.  Results  The incidence of intraoperative hypothermia (24.00%, 12/50) and the incidence of shivering (2.00%, 1/50) were lower than in the control group [48.00% (24/50), 18.00% (9/50), P < 0.05], respectively. There were no significant differences in body temperature between the two groups upon operating room entry, after induction of anesthesia, or at the beginning of surgery (P>0.05). At 15 minutes, 30 minutes, at the end of surgery, and 15 minutes after surgery, body temperature was significantly higher in the observation group (P < 0.05). After surgery, the levels of ACTH [(46.80±8.93) pg/mL] and CRH [(24.59±5.13) ng/mL] in the observation group were lower than in the control group [(51.38±10.37) pg/mL, (28.15±6.36) ng/mL, P < 0.05]. Additionally, the observation group showed higher levels of APTT, PT, and TT, and lower levels of FIB compared to the control group (P < 0.05).  Conclusion  A risk early warning intervention program can effectively maintain the intraoperative body temperature in elderly patients undergoing knee replacement under general anesthesia, reduce the incidence of intraoperative hypothermia and shivering, attenuate the stress response, and support the stability of blood coagulation function.
