Abstract

BACKGROUND

During beating heart surgery, the accuracy of cardiac output (CO) measurement techniques may be influenced by several factors. This study was conducted to analyze the clinical agreement among stat CO mode (SCO), continuous CO mode (CCO), arterial pressure waveform-based CO estimation (APCO), and transesophageal Doppler ultrasound technique (UCCO) according to the vessel anastomosis sites.

METHODS

This study was prospectively performed in 25 patients who would be undergoing elective OPCAB. Hemodynamic variables were recorded at the following time points: during left anterior descending (LAD) anastomosis at 1 min and 5 min; during obtuse marginal (OM) anastomosis at 1 min and 5 min: and during right coronary artery (RCA) anastomosis at 1 min and 5 min. The variables measured including the SCO, CCO, APCO, and UCCO.

RESULTS

CO measurement techniques showed different correlations according to vessel anastomosis site. However, the percent error observed was higher than the value of 30% postulated by the criteria of Critchley and Critchley during all study periods for all CO measurement techniques.

CONCLUSIONS

In the beating heart procedure, SCO, CCO and APCO showed different correlations according to the vessel anastomosis sites and did not agree with UCCO. CO values from the various measurement techniques should be interpreted with caution during OPCAB.

摘要

背景

在心脏不停跳手术中，心输出量（CO）测量技术的准确性可能会受到多种因素的影响。本研究旨在分析根据吻合部位，静态 CO 模式（SCO）、连续 CO 模式（CCO）、基于动脉压力波形的 CO 估计（APCO）和经食管超声心动图技术（UCCO）之间的临床一致性。

方法

本前瞻性研究纳入了 25 例行择期不停跳冠状动脉旁路移植术（OPCAB）的患者。在以下时间点记录血流动力学变量：左前降支（LAD）吻合 1 分钟和 5 分钟时；钝缘支（OM）吻合 1 分钟和 5 分钟时；右冠状动脉（RCA）吻合 1 分钟和 5 分钟时。测量的变量包括 SCO、CCO、APCO 和 UCCO。

结果

根据吻合部位，CO 测量技术显示出不同的相关性。然而，在所有研究期间，所有 CO 测量技术的 Critchley 和 Critchley 标准规定的 30%误差值都高于观察到的百分比误差值。

结论

在心脏不停跳手术中，SCO、CCO 和 APCO 根据吻合部位显示出不同的相关性，与 UCCO 不一致。在 OPCAB 期间，应谨慎解读各种测量技术的 CO 值。
