Abstract: Objective To compare the effects of two different anesthesia methods in patients undergoing ankle arthroscopic surgery. Methods Sixty adult patients undergoing ankle arthroscopic surgery in Sun Yat-sen Memorial Hospital from January 2018 to December 2019 were randomly divided into femoral nerve group and lumbar plexus group, with 30 cases in each group. The femoral nerve group received combination of femoral nerve with sciatic nerve block, and the lumbar plexus group received combination of lumbar plexus with sciatic nerve block. The effects of anesthesia and analgesia, the operation time of anesthesia, heart rate and mean blood pressure at different times, complications and adverse reactions of anesthesia were compared between the two groups. Results There were no statistically significant differences between the two groups in the number of patients who used supplementary local anesthetics and anesthetic analgesic drugs during the operation, VAS score at rest or with movement and the number patients who used additional analgesics within 24 hours after the operation. The anesthetic operation time of femoral nerve group was significantly less than that of lumbar plexus group. The heart rate and mean blood pressure of femoral nerve group during anesthetic operation were significantly lower than that of lumbar plexus group. The side effects showed no significant differences between groups. Conclusion There were no significant difference in anesthesia and postoperative analgesia effect between combination femoral nerve with sciatic nerve block and combination lumbar plexus with sciatic nerve block during ankle arthroscopic surgery, however, the former had shorter anesthetic operation time and more stable perioperative vital signs.

Key words: combination of lumbar plexus with sciatic nerve block, combination of femoral nerve with sciatic nerve block, ankle arthroscopic surgery
