超声心动图对ICU心源性休克患者心输出量测定准确性的临床研究

摘要

目的：对入住 ICU的心源性休克患者，同时使用脉搏指示的连续性心输出量（Pulse indicator continuous cardiac output ，PiCCO ）监测技术以及超声心动图进行心输出量（Cardiac output ，CO ）测定，以PiCCO测定的有创数据为标准，对超声心动图CO测定的准确性进行评估。方法：选择2011年1月-2012年12月入住我院ICU需要进行血流动力学监测的心源性休克患者共43例，对这些患者同时进行 PiCCO监测技术以及使用双平面Simpson法进行无创CO测定，对比两者CO差异，以判断超声心动图CO测定的准确性。结果：共有40例患者获得满意的二维图像，其中男28例，女12例，最大年龄78岁，最小年龄22岁，另外3例患者因未获得满意图像而被放弃。对比结果显示，超声心动图和PiCCO测定的CO分别为（3．18±0．60）ml/min及（3．58±0．97）ml/min（P＞0．05），两组数据无显著差异。结论：超声心动图CO测定是一种快速、准确、无创的血流动力学监测技术，适合在ICU心源性休克患者中进行CO测定。%Objective :We measured cardiac output in ICU patients with cardiac shock by using (Pulse indicator con-tin3uous cardiac output ,PiCCO) and echocardiography .The aim of this study was to evaluate the accuracy of echocar-diography compared PiCCO .Methods :43 cardiac shock patients in ICU of Subei People’s Hospital of Jiangsu Province from 2011 January to 2012 December who need hemodynamic monitor were collected .For these patients ,we monitor Cardiac Output by invasive PiCCO technology and noninvasive double plane Simpson method .At last ,we can determine echocardiography CO measurement accuracy by comparing with the differences .Results:40 patients had satisfactory two-dimensional images ,28 male ,12 female ,the oldest 78 years old ,the youngest 22 years old .3 patients were aban-doned because of dissatisfactory image .CO by echocardiography and PiCCO was respectively (3 .18 ± 0 .60)ml/min and (3 .58 ± 0 .97)ml/min (P>0 .05) .Conclusion:CO measurement by echocardiography is a rapid ,accurate and noninva-sive hemodynamic monitoring technology .It is suitable for ICU patients with cardiac shock who need monitor CO .
