Esophageal Doppler is a noninvasive method used to guide fluid loading, resulting in clinical outcome benefits, especially during anesthesia. Its role in critically ill patients is still controversial.
To compare cardiac output (CO) obtained from esophageal Doppler with thermodilution, using a Swan–Ganz catheter.
Data was obtained from two medical intensive care units between February and March 2003. An esophageal probe for cardiac output monitoring was introduced in severe sepsis and septic shock patients when a pulmonary artery catheter was indicated by the attendant physician; four CO measurements were done for each patient with 6-hour intervals. CO determination by esophageal Doppler was performed simultaneously with thermodilution.
In this study, in concordance with published data, there is no evidence to support esophageal Doppler as a technique for CO continuous monitoring in the intensive care unit.
