CURY, Alexandre Ferreira et al. Safety of transesophageal echocardiography in adults: study in a multidisciplinary hospital. Arq. Bras. Cardiol. [online]. 2009, vol.93, n.5, pp.478-483. ISSN 0066-782X.

BACKGROUND: TEE is a semi-invasive tool broadly used and its utilization associated to sedatives drugs might to affect the procedure safety. OBJECTIVE: to analyze aspects of TEE safety associated to the use of Midazolan (MZ) and Flumazenil (FL) and the influence of the clinical variables on the event rate. METHOD: prospective study with 137 patients that underwent TEE with MZ associated to moderate sedation. We analyzed the following events: complications related with the topical anesthesia, with MZ use and with the procedure. Uni- and multivariate analyses were used to test the influence of the clinical variables: age, sex, stroke, myocardiopathy (MP), duration of the test, mitral regurgitation (MR) and the MZ dose. RESULTS: All patients (65±16 yrs; 58% males) finished the examination. The mean doses of MZ and FL were 4.3±1.9 mg and 0.28±0.2 mg, respectively. The duration of the examination and the mean ejection fraction (EF) were 16.4±6.1 minutes and 60±9%, respectively. Mild hypoxia (SO2<90%) was the most common event (11 patients); 3 patients (2%) presented transient hypoxia due to upper airway obstruction by probe introduction and 8 (5.8%) due to hypoxia caused by MZ use. Transient hypotension (SAP<90mmHg) occurred in 1 patient (0.7%). The multivariate analysis showed that severe MR, MP (EF<45%) and high doses of MZ (>5mg) were associated with events (p<0.001). The EF was 40%, in the group with MP and 44% in the group with severe MR and it can be a factor associated with clinical events in the last group. CONCLUSION: TEE with sedation presents a low rate of events. There were no severe events and there was no need to interrupt the examinations.
