Transesophageal echocardiography offers a noninvasive technique for the continuous monitoring of cardiac performance. The combination of 2-dimensional echocardiography and Doppler velocitometry provide assessment of cardiac anatomy, valve function and, ventricular loading conditions. Although transesophageal echocardiography has become accepted for perioperative monitoring, it is typically used in conjunction with Swan-Ganz catheterization. To supplant Swan-Ganz catheters, an echocardiographic technique to monitor cardiac output is necessary. Despite considerable effort to achieve this goal, a satisfactory technique has been difficult to realize. This paper discusses the role of cardiac output monitoring in perioperative care and critically examines echocardiographic techniques for cardiac output monitoring.
经食管超声心动图提供了一种用于连续监测心脏功能的非侵入性技术。二维超声心动图和多普勒测速法相结合可对心脏解剖结构、瓣膜功能及心室负荷情况进行评估。尽管经食管超声心动图已被用于围手术期监测，但它通常与 Swan-Ganz 导管插入术联合使用。为了取代 Swan-Ganz 导管，一种监测心输出量的超声心动图技术是必要的。尽管为实现这一目标付出了巨大努力，但一种令人满意的技术仍难以实现。本文讨论了心输出量监测在围手术期护理中的作用，并对用于心输出量监测的超声心动图技术进行了批判性审视。
