Abstract Objective: To investigate the efficacy of femoral and sciatic combined with obturator nerve blocks for analgesia in patients with lower extremity venous insufficiency compared with epidural anesthesia. Methods: One hundred ASA physical status I-III patients who were scheduled for lower extremity venous insufficiency were randomly divided into two groups: group NB (n=50) and group EA (n=50). Ultrasound-guided femoral nerve block and sciatic nerve block combined with obturator nerve blocks were performed in patients of group NB. Patients in group EA were performed with epidural anesthesia at the level of L 2/3. The procedure time for anesthesia time, the anesthesia onset time, onset time of motor block, duration of sensory and motor block, the operation time, intraoperative medications, successful rate, visual analog scale at 6 hours, 12 hours, 18 hours and 24 hours after operation were recorded. At the same time, the first time needed for analgesia after surgery, the satisfaction of patients at postoperative 24 hours and perioperative side effects were also recorded. Results: The anesthesia onset time, the operation time and the duration of sensory and motor block in group NB were obviously longer than those in group EA (P<0.05). The total amount of ropivacaine in group NB was significantly higher than that in group EA (P<0.05), while there was no significant difference in the total amount of lidocaine (P>0.05). There was no difference in successful rate between the two group (P>0.05). Lower VAS pain scores, lower morphine consumption and higher satisfaction in group NB were significantly higher than those in group EA (P<0.05). And the first time that needed for analgesia after surgery in group NB was longer than group EA (P<0.05). Conclusion: Femoral and sciatic combined with obturator nerve blocks can provide an effective anesthesia and analgesia for patients undergoing lower extremity venous insufficiency phlebectomy.
