Abstract: Objective To observe the therapeutic effect of stellate ganglion block (SGB) combined with Tianshu capsule on migraine.Methods Ninty patients with migraine were randomly divided into the trial group (n=44, treated by SGB combined with Tianshu capsule) and control group (n=46, treated by SGB only). All patients of two groups were evaluated with numeric rating score (NRS) for pain before treatment and 1 day, 3 days, 1 week, 1 month and 3 months after treatment, and the therapeutic effects of two groups were compared.Results The NRS scores of patients in the two groups at each time point decreased, but scores of patients in the trial group were significantly lower than that in the control group at 3 days, 1 month and 3 months after treatment ( P<0.05). The effective rate of the trial group was superior to that of the control group ( P<0.05).Conclusion SGB combined with Tianshu capsule is more effective on migraine and has less side effect.
