    After calculating the accuracy of the new device, the obtained data of CO and cardiac preload values, wedge pressure and intrathoracic blood volume index (ITBI), were related to the patients final outcome. Results: In 183 parallel measurements of CO, the correlation coefficient R2 of both devices for CO and systemic vessel resistance was 0.88. Mean difference between the two devices was 0.02 ?0.78 l/min. Absolute values of CO ranged from 3.1 to 15.6 l/min. Comparing the ITBI obtained from the new device (mean 912 ?136 ml/m2, within normal range) with known pulmonary capillary wedge pressure values (mean 14.4 ?5.2 mmHg, above normal range) resembled that preload was overestimated when solely regarding wedge pressure. There was no correlation of both preload parameters (R2 = 0.001). Albeit a small sample size, both mean CO and wedge pressure correlated significantly with the patients final outcome. BAPTA site However, best differentiation of final outcome states was obtained with mean ITBI. Conclusions: The reliability for CO measurements of the new transpulmonary thermodilution device is high when compared with the gold standard of a PA catheter. The measuring device is far less invasive than a PA catheter and simple in handling. Although still to be validated by a larger database, guiding hyperdynamic volume therapy with filling volumes rather than filling pressures seems promising.P158 Correlation of the monitorization with continuous esophageal echo-Doppler in critically ill patientsL Natera-Ram ez, JE Colom?Ruiz, D Rubio Pay , JC Lescas-V quez, E Rivero-Sigarroa, M M dez-Bettr , G Dom guez-Cherit Divisi de Medicina Cr ica, Instituto Nacional de Ciencias M icas y Nutrici `Salvador Zubir ‘, Vasco de Quiroga 15, Col Secc XVI, Tlalpan, CP 14000 M ico, D.F., Mexico Introduction: The cardiac output (CO) for thermodilution can have a great variability. The esophageal echo-Doppler estimates the CO for the measurement of blood in the aorta. In spite of these potencial advantage, the clinical use is limited for the lack of experience. The objective is to describe the correlation that exists between the obtaing of CO by Swan-Ganz catheter and by esophageal echoDoppler continuous aortic blood flow and CO estimated. The placing of the Doppler probe was considered a minimal invasive procedure, and it doesn have major complications. Material and methods: We included the prostective form, no random, all patients older than 18 years that required invasive mon-SCritical CareVol 5 Suppl21st International Symposium on Intensive Care and Emergency Medicineitorization for their treatmeant. A Swan-Ganz catheter (Baxter Healtcare 131F7) was placed on all by the usually form. The esophageal echo-Doppler (Hemosonic 100, Arrow International) was placed via oral/nasal passages and simultaneous measuments of CO were given, with interval of 3 min between each. The investigator was blinded by the CO by Swan-Ganz. The therapeutic decision were guided by the value of the SG catheter. For the statistical analysis we will the paired samples for patients and time of measurement. We used sofware SPSS 8.0. We made a analysis correlation for Pearson and a comparison between group with `U’ Mann hitney for a significant statistic between populations of P < 0.05. We obtained difference of the medications by descriptive statistic, the inferencial analysis was m.
