“…Examinations using TEE are considered safe when conducted in a controlled environment by trained operators. 2 Information obtained from TEE can have a significant impact in cardiac [3][4][5][6][7][8][9] and non-cardiac surgery, [10][11][12] as well as in making decisions in the ICU. 11,13,14 Considering the widespread application of this technique, it is important to address the issue of safety.…”

Purpose: The use of transesophageal echocardiography has increased over the past several years. It is generally considered a safe diagnostic and monitoring tool. Whereas complications associated with echocardiographic examination rarely occur, such complications must be known to echocardiographers performing these examinations. The purpose of this review is to summarize potential complications associated with transesophageal echocardiography. Sources:A systematic search of the English and French literature was undertaken using PubMed from the National Library of Medicine. Relevant articles were obtained from a Medline search spanning the years 1975 -2007, and their reference lists were used to retrieve additional articles. Principal findings:Complications of transesophageal echocardiography are primarily related to the gastrointestinal, cardiovascular, and respiratory systems, and include infection, toxic drug reaction, local reaction through contamination of the probe, and ultrasound cavitation. Strategies to prevent these complications are reviewed. Conclusion:Whereas transesophageal echocardiography is associated with a low complication rate, the echocardiographer must be knowledgeable about the types of complications and their predisposing factors, and should be meticulous in preventing their occurrence.

“…There are several commercially available monitoring systems, but transoesophageal echocardiography (TOE) was not as extensively studied in noncardiac [1] as it was in cardiac surgery [2–5]. Due to its unique ability for cardiac imaging, assessing left ventricular (LV) function and right heart chambers dimensions, it is considered promising [5].…”

A pilot study aimed to introduce intraoperative monitoring of liver surgery using transoesophageal echocardiography (TEE) is described. A set of TEE measurements was established as a protocol, consisting of left atrial (LA) dimension at the aortic valve plane; mitral velocity flow integral, calculation of stroke volume and cardiac output (CO); mitral annular plane systolic excursion; finally, right atrial area. A total of 165 measurements (on 21 patients) were performed, 31 occurring during hypotension. The conclusions reached were during acute blood loss LA dimension changed earlier than CVP, and, in one patient, a dynamic left ventricular (LV) obstruction was observed; in 3 patients a transient LV systolic dysfunction was documented. The comparison between 39 CO paired measurements obtained by TEE and PiCCO2 revealed a statistically significant correlation (P < 0.001, r = 0.83). In this pilot study TEE successfully answered the questions raised by the anesthesiologists. Larger cohort studies are needed to address this issue.

The goal of hemodynamic monitoring and management during major surgery is to guarantee adequate organ perfusion, a major prerequisite for adequate tissue oxygenation and thus, end-organ function. Further, hemodynamic monitoring should serve to prevent, detect, and to effectively guide treatment of potentially life-threatening hemodynamic events, such as severe hypovolemia due to hemorrhage, or cardiac failure. The ideal monitoring device does not exist, but some conditions must be met: it should be easy and operator-independently to use; it should provide adequate, reproducible information in real time. In this review we discuss in particular the role of intraoperative use of transesophageal echocardiography (TOE). Although TOE has gained special relevance in cardiac surgery, its role in major non cardiac surgery is still to be determined. We particularly focus on its ability to provide measurements of cardiac output (CO), and its role to guide fluid therapy. Within the last decade, concepts oriented on optimizing stroke volume and cardiac output mainly by fluid administration and guided by continuous monitoring of cardiac output or so called functional parameters of cardiac preload gained particular attention. Although they are potentially linked to an increased amount of fluid infusion, recent data give evidence that such pre-emptive concepts of hemodynamic optimization result in a decrease in morbidity and mortality. As TOE allows a real time direct visualization of cardiac structures, other potentially important advantages of its use also outside the cardiac surgery operation room can be postulated, namely the ability to evaluate the anatomical and functional integrity of the left and the right heart chambers. Finally, a practical approach to TOE monitoring is presented, based on a local experience.
