Résumé
Objective To investigate the immediate and cumulative effects of early acupuncture therapy on cerebral hemodynamics in patients with acute ischemic stroke. Methods Totally 60 patients with acute ischemic stroke were selected and randomly divided into treatment group and control group, with 30 patients in each group. The two groups were treated with routine Western treatment. On the basis of above, the treatment group was given acupuncture treatment (acupuncture for the first time before the use of circulating medication), 30 minutes for each needle, 1 needle every 10 minutes, once per day. The treatment for both groups lasted for 14 d. The changes of systolic peak velocity (Vs), diastolic peak velocity (Vd), pulsatility index (PI) and resistance index (RI) of middle cerebral artery (MCA) in the two groups were observed. Results Compared with before treatment, both Vs and Vd increased and both PI and RI decreased in the treament group (P＜0.05); Compared with the treatment for 1 d, both Vs and Vd increased and both PI and RI decreased in the treament group after treatment (P＜0.05). Compared with before treatment, Vs, Vd, PI, RI in the treatment group and Vs and PI in the control group were significantly improved after treatment (P＜0.05). After treatment, the improvement of Vs, Vd, PI and RI in the treatment group was better than that in the control group (P＜0.05). Conclusion Early acupuncture has immediate and cumulative effects on cerebral blood flow in patients with acute ischemic stroke. Many times of acupuncture may strengthen the effects of acupuncture.
