我们使用同时热稀释和经食管脉冲多普勒超声心动图技术测量了 12 名接受选择性腹部血管手术的患者在手术过程中特定时间的心输出量。手术前没有患者有瓣膜性心脏病的临床证据。五名患者在彩色多普勒上有二尖瓣反流的超声心动图证据。使用 Bland 和 Altman 分析比较两种技术的心输出量测量结果，与热稀释技术相比，多普勒方法高估了心输出量（偏差 = 0.86 升 min-1），并且两种技术之间存在广泛的一致性限制（+2.4 至 -4.1 升 min-1）。然而，在七名没有二尖瓣反流证据的患者中，观察到更接近的一致性（偏差0.14升min-1）和更窄的限制（+1.6至-1.3升min-1）。我们的结论是，对于有功能的二尖瓣患者，经食管超声心动图可以准确测定心输出量。
We measured cardiac output in 12 patients undergoing elective abdominal vascular surgery at specific times during the procedure with simultaneous thermodilution and transoesophageal pulsed Doppler echocardiographic techniques. No patient had clinical evidence of valvular heart disease before surgery. Five patients had echocardiographic evidence of mitral regurgitation on colour-coded Doppler. Using Bland and Altman analysis to compare the cardiac output measurement by the two techniques, the Doppler method overestimated the cardiac output (bias = 0.86 litre min-1) compared with the thermodilution technique and there were wide limits of agreement between the two techniques (+2.4 to -4.1 litre min-1). However, in the seven patients with no evidence of mitral regurgitation, closer agreement (bias 0.14 litre min-1) and narrower limits (+1.6 to -1.3 litre min-1) were observed. We conclude that, in patients with competent mitral valves, transoesophageal echocardiograph may provide accurate determination of cardiac output.
