Abstract:
Impedance cardiography,being developed recently,is a noninvasive cardiovascular monitoring technique.In this study,fifty-eight patients undergoing open-heart operations were monitored pre-and posto-peratively by impedance cardiography.It was shown that the results were comparable with the results of other authors using indicator-dilution curves.EVI greater than 1.0?/s indicated normal cardiac fun-ction while EVI less than 0.8?/s indicated markedly subnormal cardiac function.The results indicated that EVI was a sensitive and reliable parameter to estimate myocardial function.TEI less than 1.9? was usually associated with abnormal arterial blood gas analysis,so TFI was useful to assess postoper- ative respiration insufficiency.It was concluded that impedance cardiography was helpful and dependable-in early postoperative patient care in cardiac surgery and it had the advantage of continuous,noniuva-sive,real-time monitoring.
