【摘要】：目的:通过脉波指示剂连续心排量监测法(Pi CCO)和胸腔电生物阻抗法(TEB)测定危重患者血流动力学参数的对比研究,评价两种方法的相关性。方法:对25例危重症患者同时应用Pi CCO及TEB监测心脏指数(CI)、系统性血管紧张指数(SVRI)、每搏变异率指数(SVV)、胸腔内血容积指数(ITBVI)或胸腔内液体含量指数(TFCI)等参数,每隔2 h监测1次,连续监测10次,使用Pearson分析比较所测数据的相关性。结果:CIPi CCO=(3.64±0.48)L/(min·m~2),CITEB=(2.83±0.32)L/(min·m~2),两者具有良好的相关性(r=0.802),SVRI和SVV也具有良好的相关性(r=0.785,r=0.732),但ITBVI与TFCI的相关性较差(r=0.214)。结论 :经肺热稀释法与胸腔阻抗法测定心输出量具有良好的相关性。
[Abstract]:Objective: to evaluate the correlation between pulse indicator continuous cardiac output monitoring (Pi CCO) and thoracic electrical bioimpedance (TEB) in the measurement of hemodynamic parameters in critically ill patients. Methods: 25 critically ill patients were monitored with Pi CCO and TEB at the same time, such as cardiac index, systemic vascular tension index, VVV index, intrathoracic blood volume index (ITBVI) or intrathoracic fluid content index (TFCI). Pearson was used to analyze and compare the correlation of measured data for 10 times. Results there was a good correlation between CCO=(3.64 and SVV, but there was a poor correlation between ITBVI and TFCI, but the correlation between ITBVI and TFCI was not so good as that between ITBVI and TFCI, but the correlation between ITBVI and TFCI was lower than that between ITBVI and TFCI, but there was a good correlation between ITBVI and TFCI (r = 0.802) and SVV (r = 0.785), but the correlation between ITBVI and TFCI was lower than that between ITBVI and TFCI (r = 0.21421), but the correlation between ITBVI and TFCI was lower than that between ITBVI and TFCI. Conclusion: there is a good correlation between transpulmonary thermal dilution method and thoracic impedance method in measuring cardiac output.
