In daily practice, one of the most frequent events is hypotension after the of extracorporeal circulation (ECC). The possibility of having an echocardiography from 2015 has been a guiding means in the hemodynamic state, however, the cause of this hypotension has not been clarified. The aim of this study is to find the echocardiographic parameters that are most related to refractory hypotension after ECC.

Patients undergoing atrial and interventricular communication surgeries monitored with transesophageal echocardiography were selected. The sample was stratified into two groups, hypotensive (cases) and normotensive (controls) after ECC. Observational, case-control study, retrospective. In the analysis of the total of the patients, were found statistically significant differences (p <0.05) in the echocardiographic parameters indicating hypovolemia between the groups. There were no differences in the statistics (p = 0.83) in the echocardiographic parameters of contractility.

The results showed that the ultrasonographic parameters of hypovolemia were those associated with hypotension. This allows the professional to be guided to a rational use of inotropic drugs and volume replacement.
