摘要
目的 比较研究全麻病人 ,肝切除期间血流动力学急剧变化时 ,呼气末二氧化碳 (PETCO2 )与心排出量 (CO)的相关性。方法 对 2 1例肝切除手术病人 ,放置Swan Ganz导管作血流动力学监测 ,用热稀释法测定心排出量 ,气体采集后测定PETCO2 ,定时观察PETCO2 与心排出量 ,对比两个参数间的相关性。结果 当阻断下腔静脉或大出血时 ,心指数最低值为 0 .7L·min-1·m-2 ,PETCO2 最低值为 2 0mmHg ,当开放下腔静脉或快速输血输液和大出血纠正时 ,心指数最高值为 7.0L·min-1·m-2 ,PETCO2 最高值为 4 7mmHg。PETCO2 和CO两者的相关系数为r =0 .90 ,P <0 .0 1。
Objective To investigate the relationship between end tidal Pco2 (P ET CO 2) and cardiac output (CO) during hepatectomy. Method Swan Ganz catheter was inserted into the right jugular vein of twenty one patients undergoing hepatectomy to observe the hemodynamic parameters. Cardiac output (CO) was examined by thermodilution technique. Mechanical ventilation was performed after anaesthesia induction, and P ET CO 2 was monitored continuously. The relationship between CO and P ET CO 2 was analyzed. Results A strong positive correlation was found between P ET CO 2 and CO, r =0.90, P < 0.05. Conclusion P ET CO 2 can be used as a predictor of CO. This technique is safe, simple and can be used in hemodynamic unstable patients during the major surgical procedure and in patient with poor cardiac function.
