OBJECTIVE: To discuss the mechanism of @entity2553 caused by concussion and the effect of @entity3931 on concussion. METHODS: A total of 224 @entity1 who were treated from March 1995 to October 1999 were divided into two groups randomly, ie, @entity3931 group (113 cases) and control group (111 cases). @entity2500 (BA) and the average peak forward velocity of cerebral blood flow were observed by color three-dimensional transcranial Doppler (3D- @entity12705 ) within 24 hours after admission and at the end of 3-6 days of treatment. Cerebral blood flow changes, characteristics and treatment effect were analyzed and determined by clinical main symptom disappearance rate. RESULTS: In concussion, cerebral blood flow was divided into 3 phases: cerebral blood flow low infusion dilation phase, cerebral @entity3120 phase and cerebral blood flow recovery phase. In the @entity3931 group, clinical main symptom disappearance rate was higher than that in the control group in the cerebral spasm and recovery phases with a significant difference (P < 0.01). CONCLUSIONS: @entity2553 , @entity519 and @entity63 lesion are the main pathological changes. Whether @entity75 is reversible or not is mainly determined by spasm time of cerebral blood vessel. @entity3931 has a good effect on releasing spasm and diminishing the cerebral blood flow velocity. It not only improves curative effect on concussion, but also reduces and prevents concussion sequelae. Hence, concussion @entity1 who have cerebral spasm confirmed by 3D- @entity12705 should be given @entity3931 routinely and early.
