To analyze the antalgic effect of electroacupuncture combined with hydromorphone on patients with moderate and severe cancer pain of stagnation of static blood type， and the effect on quality of life.Methods：A total of 80 cases of patients with cancer pain of malignant tumors were divided into the observation group and the control group according to the random number table method，40 cases in each group.The control group was treated with hydromorphone，and the observation group was additionally treated with electroacupuncture based on the treatment of the control group.The attack times of breakthrough pain，the scores of NRS and KPS，the adverse reactions before and after treatment and the average daily usage of hydromorphone in the two groups were recorded.Results：The total effective rate of antalgic effect was 90.0% in the observation group，significantly higher than that of 70.0% in the control group，the difference being significant(P ＜ 0.05).Before treatment，compared the attack times of breakthrough pain and the scores of NRS and KPS in the two groups，there was no significance in the difference(P ＞ 0.05).After treatment，the attack times of breakthrough pain and the scores of NRS in the two groups were decreased，while the scores of KPS were increased；the attack time of breakthrough pain and the score of NRS in the observation group were lower than those in the control group，while the score of KPS was higher；differences being significant(P ＜ 0.05).The incidence of adverse reactions was 15.0%in the observation group，significantly lower than that of 35.0%in the control group(P＜0.05).The average daily usage of hydromorphone in the observation group was less than that in the control group(P＜0.05).Conclusion：The therapy of electroacupuncture combined with hydromorphone for patients with moderate and severe cancer pain of stagnation of static blood type has significant antalgic effect and few adverse reactions，which is conducive to improving quality of life of patients and worthy of clinical promotion.
