摘要
目的:通过床旁彩色多普勒检测危重病人不同体位下。脏功能指标变化,研究体位变化对心脏功能的影响。为寻求危重患者最佳体位提供客观资料。方法:40例ICU重症卧床者,取平卧位、15°,30°、45°、60° 5个姿势。用床旁彩超测定每搏量(VS)、心排血量(CO)以计算射血分数(EF)观察不同体位变换时心功能的变化。结果:随着受试者体位改变,患者各心功能指标有所不同。结论:随着床头角度抬高心率、每搏量值存在显著差异,心排血量、射血分数无显著差异。
Objective:by bedside color Doppler detection under different postural changes of cardiac function indexes in critically ill patients, study the effects of body position changes on heart function. Provides Objective information for critically ill patients seek the best body position methods of 100 cases severe ICU bed, quping Fowler, 15° , 30°, 45° , 90° incline, side - six postures. Bedside color Doppler ultrasound measurement of stroke volume ( SV), cardiac output (CO) and cardiac index ( CI), left ventricular ejection time (ET), the ejection fraction (EF) to observe the changes of heart function when different posture transform. Conclusion cardiac function in different positions on different.
