无创血流动力学监测在急性呼吸困难鉴别诊断中的意义

目的：探讨无创血流动力监测在急性呼吸困难鉴别诊断中的意义。方法：对因急性呼吸困难住院的病例按照临床诊断分组，运用胸阻抗法行无创血流动力监测，同时作超声心动图检查。结果：左心衰组EF值及CI、VI、LCWI、LCW值均明显低于非心源性呼吸困难组（P〈O．05）PEP明显高于非心源性呼吸困难组（P〈O．05）。右心衰组TFC值明显高于非心源性呼吸困难组及左心衰组（P〈0．05）。心超测EF值及无创心功能测CI值相关系数r=0．286，两者无相关性。结论：无创血流动力学监测，为急性呼吸困难早期鉴别诊断提供了一种良好的新方法。

The Significance of Non-invasive Hemodynamic Monitor System in the Differential Diagnosis of Acute Dyspnea

Objective: To discuss the significance of the non-invasive hemodynamic monitor system in the differential diagnosis of acute dyspnoea. Methods: the cases of acute dyspnoea were divided into groups according to different clinical diagnosis, thoracic impedance method was used by the non-invasive hemodynamic monitor system. Ultracardiogram was also done. Results: EF, CI, VI. LCWI, LCW of left heart failure group were all significantly lower than that of non cardiogenic dyspnoea group ( P<0. 05 ); PEP was sificantly higher than that of non cardiogenic dyspnoea group ( P<0. 05 ). TFC of right heart failure group was significantly higher than that non cardiogenic dyspnoea group and left heart failure group ( P<0. 05 ). There was no significant correlation between EF in ultrasonic cardiogram and CI in non-invasive cardiac function monitor. Conclusion:Non-invasive hemodynamic monitor system is helpful in the early differential diagnosis of acute dysnoea.
