TI  - A comparison of the use of transoesophageal Doppler and thermodilution techniques 
      for cardiac output determination.
PG  - 136-42
AB  - Doppler cardiac output (CO) determination is discussed as a non-invasive 
      alternative to CO estimation by thermodilution. This study was designed to 
      compare the accuracy of a new transoesophageal Doppler device with the 
      thermodilution technique. In 24 patients undergoing coronary artery bypass 
      surgery, CO was determined simultaneously by the oesophageal Doppler (OD) and 
      thermodilution (TD) method in triplicate for three sample episodes: after 
      induction of anaesthesia during clinical steady-state conditions (A), after start 
      of surgery (B), and after sternotomy (C). The agreement between ODCO and TDCO 
      estimations was assessed by analysing the mean difference, indicating the 
      systematic error, and analysing the distribution of differences between the two 
      methods. The bias between ODCO and TDCO estimations was 0.38 (-0.06 to +0.81) L 
      min-1 (mean and 95% confidence interval) for sample episode A, 0.48 (-0.11 to 
      +1.1) L min-1 for sample episode B, and 0.69 (+0.08 to +1.3) L min-1 (P < 0.05 
      vs. zero) for sample episode C. Bias analysis of the log-transformed data 
      revealed that 95% of the ODCO values differed from TDCO values by 43% below to 
      50% above for sample episode A, by 39% below to 95% above for sample episode B, 
      and by 32% below to 96% above for sample episode C. Analysis of the changes in CO 
      from sample episode A to B and from sample episode B to C, expressed as 
      percentage values, showed a non-significant bias between the methods, but the 2 
      SD limits were +/-44% and +/-36% respectively. Our findings suggest that CO 
      estimation by OD cannot replace estimation by the TD method.
