TI  - [Comparison between two methods for hemodynamic measurement: thermodilution and 
      oesophageal doppler].
PG  - 349-54
AB  - OBJECTIVES: Thermodilution (TD) is the "gold standard method" for hemodynamic 
      monitoring. Some parameters can be measured by Oesophageal Doppler (OD), which is 
      simpler and less invasive. To evaluate the accuracy of OD, we compared this 
      method with TD in measurement of cardiac output (CO). METHODS: One hundred and 
      ninety two simultaneous measurements were made in 10 patients (5 male and 5 
      female) with different clinical situations, 8 with sepsis using vasoactive drugs 
      and 2 monitored for laryngectomy and liver transplantation. Measurements were 
      taken during 4 hours at 30 minute intervals. The two oesophageal dopplers used 
      DeltexR and ArrowR, were introduced between 35 and 45 cm from the nose and 
      located at the point of largest diameter of the descending aorta. In TD, we used 
      the pulmonary artery catheter (Swan Ganz BaxterR) and the DX- 2001 monitorR 
      positioning was confirmed with support of radiology and of pressures curves. 
      Measurements of CO carried out by means of TD were achieved using an iced saline 
      solution considering the mean of four measurements with less than a 5% 
      difference. The statistical method used was the Bland-Altman scatter plot and 
      dispersion graphic. RESULTS: No statistically significant difference was found 
      between the two methods for hemodyamic measurement with a correlation coefficient 
      of 0.8 for CO (Deltex DopplerR and Baxter Swan GanzR) and a correlation 
      coefficient of 0.99 for CO (Arrow DopplerR and Baxter Swan GanzR). CONCLUSION: 
      Homodynamic measurements with OD have the same accuracy as those with TD and were 
      easily obtained in the 10 patients.
