摘要
目的 研究经食管超声多普勒和温度稀释法在心输出量监测中的相关性。方法 15例ASA ～ 级 ,择期在全麻下手术的病人 ,其中嗜铬细胞瘤切除术 2例 ,心脏瓣膜置换术 13例 ,采用经食管超声多普勒 ( TED)与温度稀释法 ( TD)同体配对测定心输出量 ,进行两种心输出量测定方法的相关性研究。结果 两种方法监测下 15例病人心输出量具有良好的相关性 ,相关系数为 0 .83 ,回归方程 ( TED) =1.0 8TD- 0 .2 5 ,偏离 ( bias)为 0 .11。心脏瓣膜置换术病人主动脉阻断前两种监测方法的相关系数为 0 .85 ,TDE=1.0 9TD- 0 .16,偏离为 0 .2 3 ,主动脉阻断后两种监测方法的相关系数为0 .77,TED=1.13 TD- 0 .72 ,偏离为 - 0 .0 4。结论 经食管超声多普勒是一种无创、简便、连续的测定心输出量的方法 ,与温度稀释法有良好的相关性。
Objective To evaluate the correlation between the methods of transesophageal Doppler (TED) and thermodilution (TD) for cardiac output (CO) Methods Fifteen ASA class Ⅱ Ⅲ patients receiving elective operation during general anesthesia,were included in this study,of which 13 patients underwent cardiac valve replacement operation CO was measured simultaneously by TED and TD methods Results There was a high correlation between the two methods in CO measurement (r=0 83,P<0 01),the regression equation was as follows:TED=1 08TD-0 25,bias:0 11 During pre clamping period in valve replacement operation,the correlation coefficient was 0 85,with the regression equation TED=1 09TD-0 16,bias:0 23 During post clamping period,the correlation coefficient was 0 77,with the regression equation TED=1 13TD-0 72,bias:-0 04 Conclusion TED is a noninvasive reliable method for measurement of CO during operation
