Abstract:
Objective To investigate the effect of intravenous thrombolysis with different doses of alteplase on neurological function in patients with acute ischemic stroke.Methods 120 patients with acute ischemic stroke were selected as the research subjects.According to the admission time,the patients were divided into the observation group and the control group,60 patients in each group.The observation group was treated with low dose alteplase(0.6mg/kg),the control group was given standard dose(0.9mg/kg).The clinical curative effect,incidence rate of adverse event,NIHSS score and mRS score before and after treatment were observed and recorded in the two groups.Results Before treatment,there was no significant difference between the two groups in NIHSS score(t=0.288 0,P=0.773 9).After treatment for 3 days,the NIHSS score of the control group decreased compared with before treatment,and was lower than that of the observation group at the same period,there was significant difference between the two groups(t=0.778 5,P=0.000 0).Before treatment,the mRS score between the two groups had no siginificant difference(t=0.801 0,P=0.424 7).After treatment for 90 days,the mRS score of the two groups decreased,the difference was statistically significant(t=6.811 5,P=0.000 0).After treatment,1 patient with cerebral hemorrhage was observed in the observation group,while 3 cases in the control group,the difference between the two groups was not statistically significant(χ2=1.034 5,P=0.309 1).The mortality of the observation group was 11.47％,which of the control group was 1.67％,there was significant difference between the two groups(χ2=4.821 4,P=0.028 1).The good prognosis rate of the observation group was 45％,which of the control group was 68.33％,the difference was significant between the two groups (χ2=6.651 6,P=0.009 9).Conclusion Standard dose of alteplase in the treatment of acute ischemic stroke has better efficacy than low-dose alteplase,it has improved conditions of neurological deficits in patients,better recovery of neurological function,the prognosis is good,it can be widely recommended.
