About this trial

Fluid administration is the first-line treatment in hypovolemic states in critically ill patients. Prediction of fluid responsiveness is possible with echocardiography by assessing the variation of the sub-aortic velocity-time integral (AoVTI) during a passive leg raising test (PLR) or Mini-fluid challenge. However, VTI-Ao measurement is not feasible in all patients due to poor echogenicity. Validation of new fluid-responsiveness indices may facilitate the evaluation in this patient population. Among the available indices, variation of the sub-pulmonary VTI is a potential criterion.

Eligibility criteria

Qualifiers

Patient with measurable sub-pulmonary VTI in at least one of the two windows: parasternal short-axis or subcostal.

Patient with measurable sub-aortic VTI in apical 4-chamber view before and after PLR maneuver.

Patient with suspected hypovolemia or whose hemodynamic status justifies vasopressor infusion.

Disqualifiers

Severe left ventricular dysfunction defined by left ventricular ejection fraction (LVEF) < 30%.

Severe right ventricular dysfunction defined by TAPSE < 12 mm.

Cardiac arrhythmia or atrial fibrillation.

Abdominal compartment syndrome.
