[Intraoperative hemodynamic monitoring using transesophageal echocardiography in orthopedic surgery].

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.
