Duplex doppler examination of blood flow in renal interlobar arteries was analysed in twelve critically ill patients before and during low-dose dopamine infusion (2 micrograms/kg/min). Renal vasodilatation and increased blood flow were observed with dopamine, confirming results with indirect or invasive techniques. The doppler ultrasound technique is entirely non-invasive, is simple and quick to carry out, provides instant results, and will allow tailoring of inotropic support in critically ill patients to provide optimum renal blood flow.
对12例危重症患者在低剂量多巴胺输注前及输注过程中（2微克/千克/分钟），进行肾叶间动脉血流的双功多普勒检查分析。观察到多巴胺可使肾血管扩张并增加血流量，这证实了采用间接或侵入性技术所获得的结果。多普勒超声技术完全无创，操作简单快捷，能即刻得出结果，并且将有助于为危重症患者调整正性肌力支持以提供最佳肾血流量。
