杜布丁胺是多巴胺的衍生物,其增加心肌收缩力的作用较多巴胺强,而致心律失常和增加心率的副作用,则较异丙肾上腺素和多巴胺弱。用于低输出量心衰和急性心肌梗塞或心源性休克,较异丙肾上腺素和多巴胺安全,已日益为临床所重视。如果给药剂量过大或注入速度太快,则可引起心率增加和血压升高。所以,使用时应严格控制剂量,密切防范心率的突然增加和平均动脉压明显升高。一般应从小剂量开始,对心肌梗塞或冠心病者尤应如此。
Dopamine amine is a derivative of dopamine, its role in increasing myocardial contractility more dopamine, and arrhythmias and heart rate increases side effects, isoprenaline and dopamine weaker. For low-output heart failure and acute myocardial infarction or cardiogenic shock, more isoproterenol and dopamine safety, has increasingly been clinically important. If the dose is administered too much or the infusion rate too fast, it can cause increased heart rate and blood pressure. Therefore, the use should be strictly controlled dose, to prevent a sudden increase in heart rate and mean arterial pressure was significantly higher. The general should start from a small dose, especially for myocardial infarction or coronary heart disease.
