Résumé
Objective To explore the clinical effect of continuous infusion of dopamine and furosemide on elderly patients with refractory heart failure.Methods 76 elderly patients with heart failure were selected as the observation subjects,they were randomly divided into observation group and control group,38 cases in each group.The control group was given oxygen inhalation,the expansion of vascular,cardiac and other conventional treatment.The observation group was given conventional treatment and continuous infusion of dopamine and furosemide.Clinical efficacy and cardiac function improvement were compared between the two groups.Restlts The effective rate of observation group was 92.1％,which was higher than that of the control group (73.7％) (x2 =10.29,P ＜ 0.05).After treatment,the improvement of cardiac function between the two groups had significant difference (t =15.94,10.18,all P ＜0.05).Conclusion Continuous infusion of dopamine and furosemide in treatment of elderly patients with refractory heart failure could improve heart function,enhance curative effect.
