Abstract: Objective To observe the therapeutic effect of injection of consciousness promoted drug through carotid artery on persistent vegetate state (PVS).Methods33 PVS cases were divided into the treatment group (n=15) and control group (n=18). All patients were treated with routine therapy, but the treatment group added with injection of consciousness-promoted drug through the carotid artery. The therapeutic effects of two groups were evaluated.ResultsAfter the treatment, the therapeutic effects of patients in two groups were better than that of before treatment (P<0.05), and the treatment group was better than control group(P<0.05).ConclusionInjection of consciousness-promoted drug through the carotid artery is effective to PVS patients.
