无创血流动力学监测在急性呼吸困难鉴别诊断中的意义

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

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<0．05),PEP明显高于非心源性呼吸困难组(P<0．05)。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。

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 fight 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.
