摘要
目的探讨无创血流动力学各指标在鉴别老年人呼吸困难中的临床意义。方法将老年急性呼吸困难患者分为心源性呼吸困难组(心源性组)和非心源性呼吸困难组(非心源性组),比较2组间无创血流动力学相关指标的差异。结果心源性组心输出量(CO)、心脏指数(CI)、心肌收缩指数(ICON)较非心源性组显著降低(P<0.01),收缩时间比例(STR)、预射血前期(PEP)、左心室射血时间(LVET)显著升高(P<0.01);2组胸腔液体水平(TFC)、校正的左室射血时间(FTC)、每搏输出变异(SVV)差异无统计学意义(P>0.05)。结论无创血流动力学监测CO、CI、ICON、STR、PEP对鉴别心源性呼吸困难有重要参考价值,该方法便捷、无创,值得在老年人中推广应用。
Objective To investigate the value of the noninvasive hemodynamic monitoring in differential diagnosis of dyspnea in the elderly patients. Methods The non-invasive hemodynamic monitoring was carried out in the elderly patients with dyspnea. The patients were divided into cardiac dyspnea group and non-cardiac dyspnea group. The parameters of non-invasive hemodynamic monitoring were compared between two groups. Results The levels of cardiac output（ CO）,cardiac index（ CI） and cardiac contractility index（ ICON） were significantly lower,while the levels of systolic time ratio（ STR）,pre ejection period（ PEP）,left ventricular ejection time（ LVET） in cardiac dyspnea group were significantly higher than those in non-cardiac dyspnea group（ P0. 01）. The value of thoracic fluid content（ TFC）,flow time corrected（ FTC） and stroke volume variation（ SVV） showed no difference between two groups（ P〈0. 05）.Conclusions Non-invasive hemodynamic monitoring is helpful in differential diagnosis of dyspnea in elderly patients. It has the advantage of less invasion and convenience.
