ABSTRACT

Objective To investigate the effects of edaravone dextran combined with argatroban on neurological function,blood rheology and posterior circulation hemodynamics in patients with acute cerebral infarction in the posterior circulation.Methods One hundred and fifty-six patients with acute cerebral infarction in the posterior circulation were collected and randomly divided into the conventional treatment group,edaravone dextranol treatment group(EDD treatment group)and edaravone dextranol combined with argatroban treatment group(combined treatment group),with 52 cases in each group.The general data of patients in the three groups were collected,and the changes of NIHSS score and Barthel index,blood rheology and posterior circulation hemodynamics were evaluated before and after treatment in the three groups.Results After treatment,NIHSS scores and Barthel index were significantly lower in all three groups than before treatment(all P＜0.01).The NIHSS score and Barthel index of the combined treatment group were significantly lower than those of the EDD treatment group and the conventional treatment group after treatment(all P＜0.05).The difference in total effective rate among the three groups was statistically significant(P＜0.05),and the total effective rate among in combined treatment group was significantly better than those in the EDD treatment group and the conventional treatment group(all P＜0.05).The platelet aggregation rate,erythrocyte pressure volume,whole blood specific viscosity and plasma specific viscosity in the three groups after treatment were significantly lower than those before treatment(all P＜0.01).After treatment,the platelet aggregation rate,erythrocyte pressure volume,whole blood specific viscosity and plasma specific viscosity of combined treatment group were lower than those of EDD treatment group and conventional treatment group(all P＜0.05).Peak systolic blood flow velocity(Vs)of basilar artery,vertebral artery and posterior cerebral artery in the three groups after treatment were significantly higher than those before treatment(all P＜0.01),and resistance index(RI)was significantly lower than that before treatment(all P＜0.01).The Vs of basilar,vertebral and posterior cerebral arteries in the combined treatment group were significantly higher than those in the conventional treatment group and the EDD treatment group(all P＜0.05),and the RI was significantly lower than that in the EDD treatment group and the conventional treatment group(all P＜0.05).There was no significant difference in the comparison of adverse reactions among the three groups(all P＞0.05).Conclusion Edaravone dextranol combined with argatroban can exert a good protective effect on neurological function in patients with acute cerebral infarction in the posterior circulation by improving blood rheology and posterior circulation hemodynamics.
