Background:
Orthopedic surgery is commonly performed in elderly patients with higher cardiovascular surgical risk. Hemodynamic monitoring in these patients may prevent perioperative complications.
Aim:
To assess the usefulness of transesophageal echocardiography (TEE) for intraoperative cardiovascular monitoring during orthopedic surgery.
Material And Methods:
Patients older than 65 years subjected to orthopedic surgery using general anesthesia and with a high cardiovascular risk were studied. Intraoperative TEE was performed to assess intravascular volume, myocardial contractility and the presence of myocardial ischemia.
Results:
Fifty three patients aged 72+/-5 years were studied. Hemodynamic stability was detected in 68% of patients, mainly reflected as episodes of hypovolemia. Myocardial ischemia was detected in two patients and embolic episodes in six (11%).
Conclusions:
Intraoperative TEE was useful for the hemodynamic evaluation of patients with high cardiovascular risk.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
