Evaluation of the Association Between Right Atrial Reservoir Strain Variation and Fluid Responsiveness in Patients With Septic Shock

"In this pilot study, all included patients will undergo a TTE before (TTEt0) and after (TTEt1) the PLR maneuver, then before (TTEt2) and after the FC (TTEt3).~Passive leg raising is PLR. FC is fluid challenge. TTE, PLR and FC are routine care procedures in patient in septic shock. In this study the patient will undergo repeated image acquisition with TTE at different times as part of the study, resulting in a longer TTE procedure. The advantage of TTE is that it is a non-invasive, painless, non-irradiating procedure that can be easily performed at the patient's bedside and has no known side effects to date. TTE is a non-invasive procedure that poses no infectious or psychological risk to the patient. No additional follow-up or telephone contact will be necessary for the study. The study concludes once TTEt3 is completed."
