To observe the effectiveness and safety of electro acupuncture on Hegu point and Neiguan point to treat acute pain after surgery on anterior cervical spine.Methods：Sixty patients with cervical spine fracture who were about to be given relocation and internal fixation were randomly divided into electro acupuncture group (n=30) and drug group (n=30). Patients in electro acupuncture group were given electro acupuncture on Neigu point and Neiguan point 30 mins before the surgery and after surgery being sutured. The anesthesia method and applied drugs were the same in both groups. Results：1)As for electro acupuncture group, the average changes of arterial blood pressure and heart rate before surgery, before extubation, and after extubation were significantly different from those during the surgery (P<0.01), while the changes had no significant differences between the levels before extubation and after extubation (P>0.05); 2)Electro acupuncture had significantly shorter consciousness recovery and exubation time than the drug team(P<0.01); 3) Patients in both groups were given VAS and Ramsay evaluation 2 hours, 4 hours, 8 hours, 12 hours, 24 hours after extubation. Electro acupuncture group showed better analgesia effect within 4 hours after extubation compared with drug group (P<0.05); 4) There were 6 side effects occurred in drug group including nausea, vomiting, and constipation, and there was 1 happened in the electro acupuncture group. 5) The pressure times of PCA 24 hours after surgery were 116 times in drug group and 21 times in the electro acupuncture group, and the differences were significant (P<0.05).Conclusion：Electro acupuncture on Hegu point and Neiguan point can effectively ease the acute pain after surgery cervical spine with stable hemodynamics , short consciousness recovery and extubation time, significant analgesia effect and low side effects occurrence rate.
