LV Diastolic Function vs IVC Diameter Variation as Predictor of Fluid Responsiveness in Shock

Septic Shock Clinical Trial

Official title:
Left Ventricular Diastolic Function Compare to Inferior Vena Cava Diameter Variation as Predictor of Fluid Responsiveness in Mechanical Ventilated Patients With Shock

Clinical Trial Summary

Fluid responsive is defined as increasing in Cardiac output or Stroke volume by 10-15% after fluid challenge. Left ventricular diastolic dysfunction is associated with lower left ventricular end-diastolic volume (LVEDV) resulting in a less cardiac output increment after fluid challenge. However, Left ventricular diastolic function indicated by the Mitral E/e' ratio from transthoracic echocardiography, was rarely studied for fluid responsiveness evaluation.

Clinical Trial Description

Fluid therapy is one of the main treatments in patients with shock to increase Oxygen delivery by increasing Cardiac output or Stroke volume. However excess fluid intake may cause fluid overload, resulting in tissue edema, lung edema and organ dysfunction, which can lead to patient deterioration. Fluid responsiveness, defined as increasing in Cardiac output or Stroke volume by 10-15% after fluid challenge, is being recommended to evaluate in-patients with shock, according to European Society of Intensive Care Medicine (ESICM). Cardiac output measurement is often invasive or requires an expensive device, therefore, tests for predicting fluid responsiveness have been used to substitute direct Cardiac output measurement. Left ventricular diastolic dysfunction is associated with a decreasing Left ventricular end-diastolic volume, resulting in a less cardiac output increment after fluid challenge and can be measured by using Mitral E/e' ratio via transthoracic echocardiography. Despite being a non-invasive test, the Mitral E/e' ratio obtained from Echocardiography was rarely studied for the prediction of fluid responsiveness. ;
