Clinical study on astragalus injection and isometric hemodilution therapy in treating cerebral infarction with blood stasis syndrome(血瘀证) in elderly patients

Objective: To observe the therapeutic effects of astragalus injection and isometric hemo dilution therapy in treating cerebral infarction with blood stasis syndrome(血瘀证) in elderly patients. Methods : Sixtyfour inpatients and outpatients(43 were male and 21 were female) of cerebral infarction with blood stasis syndrome aged from 63 to 76 years old and average in (69 6±4 4)years old were selected. The patients were divided randomly into two groups: treating by routine therapy(routine therapy group, n=32 ) or by astragalus injection and isometric hemodilution therapy(treated group, n =32). The changes of hemorheology in these patients were observed before and after treatment, and the curative effects was compared between the treated group and the routine therapy group at the end of 3 weeks. Results: The clinical curative effects was superior in the treated group to that in the routine therapy group, the total effective rate in the treated group and the routine therapy group was 93 75% and 87 50% ( P 0 05). Observation on hemorheology parameters showed that whole blood viscosity, erythrocyte specific volume and fibrinogen in treated group after treatment were superior to that in the routine therapy group or before the treatment. Conclusion : The research suggests that it is more effective in treating elderly patients of cerebral infarction with blood stasis syndrome by astragalus injection and isometric hemodilution therapy than by routine therapy. It has the effect of decreasing the whole blood viscosity, accelerating blood stream, alleviating clinical symptoms and reducing the rate of resulting in crippledom.
