Abstract： Objective： To observe the application effect of continuous transcutaneous electrical stimulation at Hegu point (LI 4)， Neiguan point (PC 6)， and Zusanli point (ST 36) on supplemental anesthesia for lung cancer surgery. Methods：A total of 103 cases of patients undergoing radical surgery for lung cancer under general anesthesia were randomly divided into the observation group and the control group，with 52 and 51 cases in each group respectively. The lung cancer radical surgery in the two groups was performed under conventional anesthesia. During anesthesia， the observation group was given continuous transcutaneous electrical stimulation at Hegu point (LI 4)， Neiguan point (PC 6)， and Zusanli point (ST 36) on the two sides. In the control group，electrodes were placed at the corresponding points， but without electrical stimulation. Hemodynamics [heart rate (HR) and mean arterial pressure (MAP)]， intraoperative anesthetic dosage， postoperative anesthesia recovery quality， pain situation (VAS score)， and incidence of adverse reactions were compared between two groups during the perioperative period [10 minutes before anesthesia induction (T0)， skin incision (T1)， pleural cavity opening (T2)， surgery completion (T3)， and complete awakening (T4)]. Results： There was no significant difference in the comparison of HR and MAP between the two groups during T0-T4 (P＞0.05). Dosage of Propofol and Remifentanil in the observation group was lower than that in the control group (P＜0.05)； there was no significant difference in the comparison of dosage of Sufentanil and Cisatracurium Besilate between the two groups (P＞0.05). The postoperative recovery time，extubation time，out-of-bed time，and anal exhaust time in the observation group were shorter than those in the control group (P＜0.05). The scores of 40-item Quality of Recovery Questionnaire (QoR-40) 24 hours after surgery in the observation group were higher than those in the control group (P＜0.05). At 6，12，and 24 hours postoperatively，the VAS scores in the observation group were lower than those in the control group (P＜0.05)；there was no significant difference in VAS scores between the two groups 48 hours after surgery (P＞0.05). The number of pressing of the analgesic pump within 48 hours in the observation group was less than that in the control group (P＜0.05). After surgery， the incidence of adverse reactions was 7.69% in the observation group and 29.41% in the control group， the difference being significant (P＜0.05). Conclusion： During lung cancer surgery， continuous transcutaneous electrical stimulation at Hegu point (LI 4)， Neiguan point (PC 6)， and Zusanli point (ST 36) can reduce the dosage of anesthetic drugs，improve the quality of anesthesia recovery，and conduce to relieve postoperative pain and reduce adverse reactions to anesthesia.
