“…Another requirement is that of the immediate availability of a hard copy of the ECG for more detailed analysis. Studies have reported that even trained observers recognise only 15–40% of ischaemic ECG events displayed on the oscilloscope [13, 14]. Our data are in agreement with other authors using ECG and biplane TOE [9, 15] but are not in agreement with those of Eisenberg et al .…”

SummaryThe role of transoesophageal echocardiography (TOE) in anaesthesia remains controversial because it is a rapidly evolving technique with few proven benefits and considerable cost. Recently, the Society of Cardiovascular Anaesthesiologists has published practice guidelines for the use of peri-operative TOE. To determine the current role of transoesophageal echocardiography and the relative impact of category-based transoesophageal echocardiographic indications the present study investigated its use in seven Western European countries. The study sample was taken from a prospective cohort of 224 patients with acute or chronic haemodynamic disturbances or at risk of myocardial ischaemia. All patients were monitored with two-lead electrocardiography and radial and pulmonary artery catheters, as well as biplane or multiplane transoesophageal echocardiography. A total of 2232 clinical interventions were made in these patients. The most frequently observed intervention was the administration of a fluid bolus (45% of all interventions). Overall, transoesophageal echocardiography was the most important guiding factor in 560 (25%) interventions. It was the most important monitor in guiding the following therapeutic interventions: anti-ischaemic therapy -207 of 372 interventions (56%); fluid administration -275 of 996 (28%) interventions; vasopressor or inotrope administration -56 of 316 (16%) interventions; vasodilator therapy -six of 142 (4%) interventions and depth of anaesthesiafour of 211 (2%) interventions. We found that transoesophageal echocardiography is frequently influential in guiding clinical decision making and is used most frequently for category II indications but category I indications were associated with more frequent change in management.

“…Several authors have documented the value of TEE in the early detection of myocardial ischemia and infarction during surgery, [126][127][128] whereas others have questioned its value. 129 Biplane TEE seems superior to the monoplane approach for detecting segmental wall-motion abnormalities, 130 and myocardial ischemia may be detected more easily by this approach than by hemodynamic monitoring. 131,132 Monitoring of ventricular function by TEE is helpful for detecting hypovolemia and hypervolemia 133 and for weaning patients from cardiopulmonary-bypass or ventricular-assist devices.…”

“…Luftbedingte "reverberations" können auch durch Interposition von Lungenanteilen oder durch ein zwischen Zwerchfell und Magen liegendes, gasgefülltes Kolon hervorgerufen werden. Limitierungen bei der linksventrikulären Anschallung beruhen nicht selten auf interindividuellen Variationen oder operationsbedingten Verschiebungen der Herzachse, sowie auch auf einer Dilatation des Herzens oder einem zu kleinen Magen (133). Uber die Inzidenz nicht adäquat beschallbarer Patienten liegen in der Literatur keine verldlichen Zahlen vor.…”

Transoesophageal echocardiography (TEE) is a visualising ultrasound technique that has entered the arena of anaesthesiology and intensive care shortly after its clinical introduction in the early 80s. Due to transducer positioning close to the heart, two-dimensional echocardiograms render high spatial resolution of cardiac structures and in adequate views continuously demonstrate the complete course of cardiac filling and contraction. The high sensitivity of the method, numerous options to assess morphological and functional parameters, and the low related risk involved for the patient explain the growing interest in TEE as a perioperative monitoring device. This utilisation, however, is currently limited by the high costs of the ultrasound equipment, the demand for specialists knowledge, the cost-benefit relation not yet thoroughly explored and the little propagated knowledge of the method's capacity. In addition, the need for information is growing due to the permanent technological progress of the equipment, which recurrently requires actualization in evaluating TEE.
