BACKGROUND: Pulse wave analysis (PWA) allows cardiac output (CO) measurement after calibration by transpulmonary thermodilution. A PWA system that does not require previous calibration, the FloTrac/Vigileo (FTV), has been recently developed. We compared determinations of CO made with the FTV to simultaneous measurements using transesophageal echocardiography (TEE). METHOD: Ten ASA I-II patients scheduled for laparoscopic colorectal surgery were studied. A radial 20-gauge cannula was inserted and connected to a hemodynamic monitor and a FTV system for PWA and determination of CO (CO(PWA)). TEE CO (CO(TEE)) was determined as previously described. Measurements were made after intubation, 5 min after establishing the lithotomy position, 5 min after establishing pneumoperitoneum, every 30 min, or each time mean arterial blood pressure decreased below basal values. Statistical analysis was made with the Bland and Altman method. RESULTS: Eighty-eight measurements were compared. The CO(TEE) values ranged from 3.23 to 12 Lt/min (mean 6.21 +/- 1.85). Values for CO(PWA) ranged from 2.9 to 8.5 Lt/min (mean 4.84 +/- 1.14). Bias was 1.17 and limits of agreement -2.02 and 4.37. The percentage error between all CO(TEE) and CO(PWA) measurements was 40% (27%-50%) mean (range). CONCLUSION: During laparoscopic colon surgery, clinically important differences were observed between CO determinations made with TEE and FTV.

BACKGROUND: Cardiac output can be measured non invasively by transesophageal Doppler. This is an alternative to measure it by thermodilution with a catheter in the pulmonary artery. AIM: To compare both methods of cardiac output measurement. MATERIAL AND METHODS: Simultaneous measurement of cardiac output by transesophageal Doppler and thermodilution with a catheter in the pulmonary artery in four male critical patients, aged 60+/-12 years, hospitalized in a University Hospital. The Bland and Altman method to compare the concordance between two measurements, was used. RESULTS: Forty measurements were performed. The results of both methods had a correlation coefficient of 0.98. According to the Bland and Altman method, the difference between both methods was -0.5 L with a precision of 0.52 L/min (95% confidence interval -1.51 to 0.52 L/min). Considering that a change between two sequential measurements is considered significant when the difference is more than 15%, both measurements agreed in 83% of cases, that there was a change in cardiac output. CONCLUSIONS: Transesophageal Doppler is a promising non invasive technique to measure cardiac output in critical care patients. It becomes a valid alternative to the thermodilution technique. This preliminary experience must be confirmed in a larger series.

BACKGROUND: Transesophageal echocardiography allows a semi-invasive hemodynamic monitoring, during cardiac and non cardiac surgery. The benefits of such surveillance must be assessed, since it may help to change patient management. AIM: To assess the usefulness of transesophageal echocardiography during surgical procedures in critical patients. MATERIAL AND METHODS: Based on the indications of the North American Societies of Cardiology and Anesthesiology, 264 patients were monitored using a multiplanar transducer. The type of surgery, insertion difficulties, quality of visualization, complications and usefulness of the method were recorded. RESULTS: One hundred eleven cardiac and 153 non cardiac surgical procedures were monitored. In 97% of cases, visualization was good. In 2 cases, it was impossible to obtain a transgastric axis. No complications of the procedure were recorded. The method was useless in nine patients, helpful to change drug and volume management in 126 (48%) patients, helpful to change perioperative management in 49 (19%) patients and was a substitute for pulmonary artery catheterization in 79 (30%) patients. CONCLUSIONS: Intraoperative transesophageal echocardiography is a safe technique that renders high quality images, with a low incidence of complications and that, when well indicated, orients therapeutic changes in 98% of patients.
