ABSTRACT

Introduction: Into the Intensive Care Unit (ICU), the measuring of the hemodynamic variables of the critical patient are important, traditionally there are obtained by the pulmonary artery flotation catheter (PAC) with all the advantages and disadvantages, but currently we have another tool that indirectly gives us information of the hemodynamic variables such as the transthoracic echocardiography (TTE). This image mode is very important in the critical patient, due to it is portable, available and with a rapid diagnosis capacity. In this context, the echocardiography could provides an important information about the hemodynamic status with more accuracy than the clinical evaluation, furthermore the fast cardiac assessment that is realized in the headboard of the patient. There are articles that describe the TTE applied in ICU as the «Swan-echo» due to it provides non invasive information about the measuring of the cardiac output, the right atrial pressure, the pulmonary pressures and the left ventricle filling pressure.
Objective: Determinate the correlation of the hemodynamic information obtained by the TTE with the pulmonary artery flotation catheter in postoperative patients with cardiac surgery.
Materials and methods: Prospective, transversal, cross-sectional, observational and comparative studies, where there were included 44 patients POP with cardiac surgery, which 10 did not have an adequate echocardiographic window. Thirty four patients were included in this study, which were studied the hemodynamics variables: right auricle pressure (RAP), pulmonary artery occlusion pressure (PAOP), systolic pulmonary artery pressure (SPAP) and cardiac output (CO), through TTE and PAFC.
Results: In general by measuring the variability of the pressures and cardiac output, there were no differences in both averages, as well as a good correlation of both.
Conclusions: TTE allows an adequate hemodynamic estimation; these measurements could be performed in less invasive way than pulmonary artery flotation catheter, therefore less risks for the patient.
