Abstract： Objective： To observe the effect of electric point stimulation in Chinese medicine and combined spinalepidural anesthesia on the temperature， score of Mini- Mental State Examination(MMSE) and awakening time in elderly patients undergoing lower extremity surgery in orthopedics department. Methods：A total of 64 elderly patients undergoing lower limb surgery in our hospital were randomly divided into two groups，32 cases in each group. The control group was given combined spinal-epidural anesthesia，and the study group was additionally given electric point stimulation based on the treatment of the control group. Changes of temperature in the two groups were monitored；the MMSE scores，awakening time，operation time and intra-operative blood loss were compared，and the changes of hemorheological indexes in the two groups were recorded. Results：Thirty minutes after skin incision，the temperature in both groups was significantly lower than that before the intervention respectively(P＜0.05). Ninety minutes after skin incision，the temperature in both groups was significantly lower than that before the intervention and thirty minutes after skin incision(P＜0.05). The temperature in the study group thirty minutes and ninety minutes after skin incision was higher than that in the control group respectively (P＜0.05). After the intervention，the MMSE score in the study group was significantly higher than that in the control group (P＜0.05). The awakening time，operation time and intraoperative blood loss in the study group were significantly less than those in the control group(P＜0.05). After the intervention，in addition to plasma viscosity in the control group，indexes such as high whole blood viscosity，low whole blood viscosity，plasma viscosity，hematocrit，platelet adhesion rate in patients were significantly improved when compared with those before intervention(P＜0.05)， and the improvement in the study group was significant(P＜0.05)，and was better than that in the control group(P＜0.05). Conclusion：Electric point stimulation in Chinese medicine and combined spinal-epidural anesthesia，can effectively control the rate of reduction of temperature in elderly patients undergoing lower extremity surgery，reduce the awakening time，operation time and intraoperative blood loss，and improve their mental state and hemorheological indexes.
