CABRERA SEN, María Carolina et al. Intraoperative hemodynamic monitoring using transesophageal echocardiography in orthopedic su. Rev. méd. Chile [online]. 2008, vol.136, n.9, pp.1127-1133. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872008000900006.

Background: Orthopedic surgery is commonly performed in elderly patients with higher cardiovascular surgical risk. Hemodynamic monitoring in these patients may prevent períoperative complications. Aim: To assess the usefulness of transesophageal echocargiography (TEE) for intraoperative cardiovascular monitoring duríng 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 reñected 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.
