Objective To study and analyze the therapeutic effect of Oza Grey Na (continuous micro pump infusion) on cerebral infarction. Methods 100 patients with cerebral infarction treated in our hospital from February 2015 to August 2016 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. The patients in the control group received routine treatment, while the experimental group received Oza Grey Na (continuous micro pump) treatment, intravenous drip, 1 courses for 2 weeks. The liver and kidney function, coagulation function, blood routine and other indexes of the patients in the experimental group and the control group were examined before and after treatment, and the therapeutic effects of the two groups were compared and analyzed. Results After treatment, 50 patients in the experimental group were invalid, 3 cases were effective, 20 cases were markedly effective, and the total effective number was 47 cases in 27 cases. Patients in the control group, 8 patients were invalid, 18 patients were effective, 24 patients were markedly effective, and the total effective number was 42 cases. The effective rate of the treatment group was 94％, and the effective rate of the control group was 84％, which was lower than that of the experimental group (P<0.05). There were no severe complications in the experimental group and the control group, and there was no significant difference in the incidence of complications between the 2 groups, and there was no statistical significance. Conclusion Oza Grey Na (continuous micro pump) treatment of cerebral infarction clinical effect is better, more efficient, with further clinical promotion and application of significance.
