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.

<p><b>OBJECTIVE</b>To observe the effectiveness and safety of electroacupuncture (EA) at Neimadian (Extra) and Neiguan (PC 6) for analgesia after thoracic surgery.</p><p><b>METHODS</b>One hundred and twenty cases of thoracic surgery were randomly divided into an electroacupuncture (EA) group (60 cases) and a medication group (60 cases). EA was applied at Neimadian (Extra) and Neiguan (PC 6) for postoperation analgesia in the EA group, while patient-controlled intravenous analgesia (PCIA) was applied in the medication group. The score of visual analogue scale (VAS), analgesia effect, safety and beta-endorphin level after the treatment in both groups were compared.</p><p><b>RESULTS</b>Compared with those before the treatment, the VAS scores in every time point after surgery were decreased (all P < 0.05), which were lower in the EA group (P < 0.01). The excellent and good rates were 96.7% (58/60) and 75.0% (45/60) seperately, the analgesia effect in the EA group (2 h after operation) was superior to that in the medication group (P < 0.01). The safety degree in EA group was higher to that in the medication group (P < 0.01). Compared with that before the treatment, the beta-endorphin level in two groups after treatment was both increased, which was higher in the EA group (P < 0.01).</p><p><b>CONCLUSION</b>Electroacupuncture at Neimadian (Extra) and Neiguan (PC 6) has better analgesia effect (2 h after operation) and safety than PICA on analgesia after thoracic surgery.</p>
