Clinical significance of PA catheter is controversial. FloTrac sensor bases its calculations on arterial waveform characteristics. We conducted a pilot assessment of the FloTrac sensor by three versions comparing with pulmonary artery catheter (PCA) methodology.
Five patients undergoing cardiac surgery and four patients undergoing renal transplantation were enrolled. A PAC was inserted and radial arterial access was used for semi-invasive determination of CO (APCO) with the Vigileo. CO was measured simultaneously by bolus thermodilution and the Vigileo technique, and CCO was measured simultaneously.
The correlation with output obtained by FloTrac and obtained by PCA is better with the newer version. Bland Altman analyses demonstrated better agreement between FloTrac and PCA methodology of the newer version.
CO measured by a new semi-invasive arterial pressure waveform analysis device showed better agreement with pulmonary artery thermodilution measurement of the newer version.
肺动脉导管的临床意义存在争议。FloTrac传感器基于动脉波形特征进行计算。我们通过三个版本与肺动脉导管（PCA）方法进行比较，对FloTrac传感器进行了初步评估。
纳入5例接受心脏手术的患者和4例接受肾移植的患者。插入肺动脉导管，并使用桡动脉通路通过Vigileo进行CO（APCO）的半侵入性测定。通过团注热稀释法和Vigileo技术同时测量CO，并同时测量CCO。
较新版本的FloTrac与PCA获得的输出之间的相关性更好。Bland Altman分析表明，较新版本的FloTrac与PCA方法之间的一致性更好。
通过一种新型半侵入性动脉压波形分析装置测量的CO与较新版本的肺动脉热稀释测量结果显示出更好的一致性。
