TI  - Thoracic electrical bioimpedance versus thermodilution in patients post 
      open-heart surgery.
PG  - 19-23
AB  - Thoracic electrical bioimpedance cardiography is a non-invasive, continuous and 
      low-cost method of estimation of cardiac output and other haemodynamic 
      parameters. Though subject to continuous technological refinement controversial 
      opinions exist on its validity in subsets of critically ill patients, patients 
      with heart disease or after cardiac surgery. A comparison study between 
      thermodilution (TD) and bioimpedance (TEB) was performed in 28 patients 
      undergoing elective cardiac surgery (CABG, aortic or mitral valve replacement or 
      combined procedures). 128 pairs of cardiac index estimates at specific time 
      points during 20 hours at the postoperative ICU were evaluated. A poor 
      correlation (r = 0.26, p < 0.05, bias -0.07 l.min-1.m2, precision + 1.1 
      l.min-1.m-2, 95% limits of agreement -2.27-2.13 l.min-1.m-2) between TD and TEB 
      cannot support the routine use of TEB monitoring in early postoperative period 
      after open-heart surgery. Possible reasons of lack of agreement in this 
      population are discussed. Further studies with technically improved bioimpedance 
      cardiographs will be needed.
