脉搏轮廓心排血量监测技术在危重病患者血流动力学监测中的应用

Application of pulse contour cardiac output monitoring technique in hemodynamic monitoring in critical patients

血流动力学监测对判断危重症患者病情及指导患者液体治疗具有重要意义。临床上，血流动力学监测的手段分为有创监测和无创监测2种，前者包括动脉压、中心静脉压（CVP）、心排血量（CO）、肺动脉压、肺动脉楔压（PAWP）等指标的有创监测，后者包括血压、心率、呼吸频率、脉搏血氧饱和度和尿量等指标的无创监测。以往有创监测手段多以肺动脉漂浮导管（Swan-Ganz导管）监测为主，近年来脉搏轮廓心排血量（pulse contour cardiac output，PiCCO）监测技术在血流动力学监测中的应用越来越受到重视，本文就有关应用进展进行综述。

Pulse contour cardiac output （PiCCO） monitoring is a new type of invasive hemodynamic monitoring technology,which is more and more often applied in perioperative period and the patients suffering from multiple injuries,septic shock,and extensive burn.With PiCCO one is able to monitor patients; hemodynamic indexes safely,timely,accurately,and continuously to provide reference for judgment of patients＆#39; condition and proper quality and quantity of fluid administration.This technique has a good prospect in clinical application.
