ABSTRACT
OBJECTIVE:To observe the clinical efficacy and safety of nitroprusside combined with dopamine in the treatment of acute heart failure(AHF). METHODS:96 patients with AHF were randomly divided into control group and research group. All patients were given ACEIs,digoxin,diuretics,statins,aspirin and other conventional treatment. On this basis,control group was given nitroprusside 12.5-25.0 mg,adding into 5% Glucose solution 50 ml by micro pump and started at 6.25 μg/min,and then maintained at 12.5-50.0 μg/min based on the blood pressure adjustment;research group was given dopamine 100 mg based on the treatment of control group,adding into 5% Glucose solution 50 ml at rate of 2 μg/(kg·min)by pump,and maintained at 2-10 μg/(kg·min). The course of both was 5-7 d. The clinic data was observed,including clinical efficacy,hemodynamic parameters(cen-tral venous pressure,pulmonary artery systolic pressure,heart rate and cardiac output index)before and 0.5,3,12,24 and 48 h af-ter treatment,renal functions(serum potassium,blood urea nitrogen,serum creatinine and 24 h urine)before and 24,48 and 72 h after treatment,and the incidence of adverse reaction. RESULTS:The total effective rate in research group was significantly higher than control group,with significant difference(P0.05). There were no significant differences in the incidence of adverse reactions(P>0.05). CONCLUSIONS:Nitroprusside combined with dopamine has more obvious efficacy than only nitroprusside in the treatment of AHF,and can obviously reduce the cardiac stress,increase cardiac output and improve renal function,with similar safety.
