Are measurements of cardiac output obtained with transesophageal echocardiography and pulmonary artery thermodilution interchangeable?
In comparison, CO measurements obtained with TEE and PAC TD had wide limits of agreement, a larger percentage error than would be expected from the precision of the two methods, and a poor trending ability. Thus, TEE is not interchangeable with PAC TD for measuring CO.
TEM is a safe technique with low morbidity and recurrence rates. Over time, experience leads to a reduction in operation time, length of patients' hospital stay and complication rate. TEM remains the treatment of choice for benign lesions and stage T1 rectal carcinomas in selected patients.
