Perioperative use of the oesophageal Doppler probe (ODM II) on a patient scheduled for transmyocardial revascularization

Abstract

We describe the use of the continuous wave oesophageal Doppler monitor (ODM II) in the perioperative management of a patient with chronic obstructive coronary artery disease undergoing transmyocardial revascularization (TMR). The use of ODM II allowed both quantitative and qualitative assessment of cardiac function relatively noninvasively. It detected the successful transmyocardial penetration of a laser beam during operation by visual and auditory phenomena in addition to reflecting improvement in cardiac performance after operation.

Isoflurane, desflurane and sevoflurane for carotid endarterectomy

“…The oesophageal Doppler monitor and automated ST segment monitoring are valuable if considered as devices for the assessment of trends. The oesophageal Doppler monitor tends to underestimate cardiac output values in atherosclerotic patients, but its usefulness during vascular aortic surgery and cardiac surgery and as a tool for evaluating changes in cardiac output is accepted by many clinicians [22–24]. Peroperative ST segment monitoring is less specific (but more sensitive) than transoesophageal echocardiographic monitoring for the detection of myocardial ischaemia [25].…”

Change in stroke volume in response to fluid challenge: assessment using esophageal Doppler

“…The esophageal Doppler probe (Cardio Q, Deltex Medical Limited, Chichester, UK) is approved for clinical use, and is routinely used in several institutions [11,12,13]. It is placed into the esophagus either through the mouth or the nose.…”

Minimally Invasive and Noninvasive Diagnosis and Therapy in Critically Ill and Injured Patients

“…24,25 Although the EDM has been approved by the Food and Drug Administration and has numerous studies documenting its accuracy as a monitoring device, its use has been sporadic, particularly in North American centers. [26][27][28] The EDM poses several advantages over the pulmonary artery flotation (PA) catheter, the primary bedside de-vice used to determine cardiac output. Unlike the invasive PA catheter, the EDM does not require percutaneous insertion, which can be complicated by pneumothorax or arrhythmia.…”
