Implication

Avoid relying on transoesophageal echocardiography for cardiac output after CABG; challenges interchangeability with thermodilution in ICU monitoring.

Does transoesophageal echocardiography reliably measure cardiac output compared to thermodilution in patients after coronary artery bypass grafting?

Population

30 patients undergoing coronary artery bypass grafting, measured postoperatively after stabilisation in the intensive care unit

Intervention

Transoesophageal echocardiography (TEE) for determining cardiac output (measured through aortic, mitral, pulmonary valves, RVOT, LVOT, transgastric surface areas, and 2D volumes)

Comparator

Thermodilution

Outcome

Agreement of cardiac output measurement with thermodilution (limit of agreement set at 30%)surrogate

Transoesophageal echocardiography is unreliable for assessing cardiac output in post-cardiac surgery patients in the ICU when compared to thermodilution.
