ABSTRACT
OBJECTIVE@#To compare the clinical effect between electroacupuncture (EA) at Neima point and Neiguan (PC 6) and epidural nerve block for preemptive analgesia in patients undergoing thoracic surgery.@*METHODS@#Sixty patients with elective radical esophagectomy were randomly divided into a group A, a group B and a control group, 20 cases in each group. The patients in the group A were treated with injection of 20 mL 0.375% ropivacaine at epidural space 30 min before anesthesia induction, followed by normal anesthesia during operation; the patients in the group B were treated with 30 min EA at bilateral Neima point and Neiguan (PC 6) before anesthesia induction, followed by normal anesthesia during operation; the patients in the control group were treated with general anesthesia alone. Patient-controlled intravenous analgesia was applied for all the patients. The mean arterial pressure (MAP) and heart rate (HR) were recorded at the following time points: before acupuncture/epidural puncture (T@*RESULTS@#The MAP at T@*CONCLUSION@#The preemptive analgesia of EA at Neima point and Neiguan (PC 6) and epidural nerve block could both provide effective perioperative analgesia for thoracic surgery. The EA could better maintain intraoperative hemodynamics and has less physiological disturbance.
