目的：对85例接受3～5根冠脉搭桥手术病人测得的围术期混合静脉血氧饱和度SvO2和心脏指数(CI)等血流动力学指标进行统计学分析，探索其相关性。方法：采用有光纤的5腔肺动脉漂浮导管(Baxter，CCI/SvO2/VIPTm，Edwards Swas-Ganz)，分别在六个时相采取血流动力学参数：麻醉前基础值、气管插管后5分钟、锯开胸骨后、体外循环停机后、术后6和24小时。结果：SvO2与CI在各时相无显著改变或高于术前水平。各时相SvO2和CI与对照值之差间显示较好的相关性。结论：冠脉搭桥手术病人围术期监测SvO2有助于及时了解CI的动态改变。

Objective:Cardiac index(CI) and mixed venous oxygen saturation SvO2 were studied in 85 patients undergoing coronary artery bypass grafting(CABG). Methods: Measurement of CI and SvO2 was carried out with a fiberoptic ballon-tip thermodilation pulmonary artery catheter. Fentanyl-based anesthesia was applied in all patients. Hemodynamic parame-ters were obtained prior to anesthesia induction as the baseline, after endotracheal intubation, after stemotomy, after weaning of cardiopulmonary bypass, at 6 and 24h after operation. Results: CI and SvO2 increased or was not changed at all time intervals, compared with the baselines. The changes of SvO2 correlated well with those of CI. Conclusion: The results suggest that continuous monitoring of SvO2 may be useful to predicting alteration in CI in patients undergoing CABG.
