Clinical Study on Acupoint Injection plus Acupuncture for Insomnia Due to Heart-kidney Disharmony

Objective： To observe the clinical efficacy of acupoint injection at Neiguan （PC 6） plus acupuncture in treating insomnia due to heart-kidney disharmony. Methods： A hundred patients with insomnia due to heart-kidney disharmony were randomized into an observation group and a control group. Fifty-three cases in the observation group were intervened by acupoint injection at Neiguan （PC 6） plus acupuncture; while 54 cases in the control group were intervened by acupuncture alone. The Pittsburgh sleep quality index （PSQI） was evaluated before and after intervention, and the therapeutic efficacies of the two groups were compared. Results： Acupoint injection at Neiguan （PC 6） plus acupuncture produced significantly higher efficacies in improving sleep quality, shortening sleep latency, and enhancing sleep efficiency than acupuncture alone （P〈0.05）. Conclusion： The two groups both can improve the condition of insomnia; acupoint injection at Neiguan （PC 6） has significant advantages, manifested by a higher therapeutic efficacy for insomnia due to heart-kidney disharmony, higher safety evaluation, efficiency, and less adverse events, thus proper for clinical application.
