摘要
目的 新一代生物阻抗法监测心排血量 (NCCOM)的临床评估。方法 冠状动脉搭桥术病人 16例 ,用阻抗法、温度稀释法和呼末CO2 法同时测定心排血量。此外用阻抗法对 2 0 0名 2 0岁以上健康人NCCOM各项参数进行测定。结果 阻抗法同温度稀释法和呼末CO2 法测定心排血量有较好的相关性。用阻抗法对健康人NCCOM各项参数测定显示老年人各项参数与其它各组相比有明显差异。
Objective To evaluate the accuracy of a new generation bioimpedance cardiac output monitor as compared with thermodilution and end expiratory CO 2 techniques Methods Sixteen patients (14 males, 2 females) aged (58±12) years undergoing elective coronary artery bypass (CAB) surgery were studied Cardiac output was measured after CAB surgery in ICU using a new generation bioimpedance cardiac output monitor(Rheo Bioimpedance Hemodynamic monitor) and conventional thermodilution technique in 16 patients and end expiratory CO 2 technique in 10 patients Cardiac output was also measured with Rheo Bioimpedance Hemodynamic monitor in 200 healthy volunteers consisting of equal numbers of male and female The volunteers of each sex were further divided into 5 equal groups of 20 each: (1)20 29 years, (2)30 39 years, (3)40 49 years, (4)50 59 years and (5)60 70 years Results Cardiac outputs measured by bioimpedance and thermodilution techniques were well correlated (r=0 83) and there was also a good correlation between cardiac outputs measured by bioimpedance and end expiratory CO 2 techniques(r=0 88) Cardiac out measured with Rheo Bioimpedance Hemodynamic monitor in 200 healthy volunteers showed that there was a significant difference in cardiac output between 60 70 years age group and the other age groups in both male and female Conclusions Cardiac output and other hemodynamic parameters measured with the new generation bioimpedance hemodynamic monitor are accurate and can be used for preoperative cardiovascular function evaluation and postoperative monitoring of dynamic changes in circulatory function
