Clinical study on Ginkgo biloba lactone injection combined with rt-PA intravenous thrombolysis in treatment of acute ischemic stroke / 药物评价研究

ABSTRACT

Objective To explore the safety and clinical efficacy of Ginkgo biloba lactone injection combined with Alteplase intravenous thrombolysis in treatment of acute ischemic stroke.Methods Totally 87 patients were recruited and divided into control group and test group.The,patients in control group (39 cases) were given Alteplase 0.9 mg/kg for injection,intravenous bolus total dose 10％ was given within 1 min,then intravenous infusion of the remaining 90％ was given in 1 h,and given basic therapy after 24 h.The 48 cases in test group,which were immediately iv Ginkgo biloba lactone injection after intravenous thrombolysis,6 mL added into 250 mL saline,once daily for 14 d,and also were given basic therapy after 24 h.All NIHSS scores were recorded before treatment,14 d and 90 d after treatment,and the adverse events were recorded.The modified Rankin scale (mRS) score and BI index were performed at 14 and 90 d after admission.Patients in two groups were classified according to the TOAST classification,and the patients with large-arteryatherosclerosis and small-artery occlusion were analyzed.Results No intracranial hemorrhage occurred in the two groups.The NIHSS score and mRS score of test group were significantly lower than that of control group,and BI index was significantly increased 90 d after treatment.The NIHSS score and mRS score of test group were significantly lower than that of control group,and BI index was significantly increased90 d after treatment of patients with large-artery atherosclerosis.But there was no significant difference between test group and control group of patients with small-artery occlusion.Conclusion Ginkgo biloba lactone injection combined with rt-PA intravenous thrombolysis in the treatment of acute ischemic stroke has high safety,and can improve the prognosis of patients.
