Diagnostic Accuracy of the Inferior Vena Cava Collapsibility to Predict Fluid Responsiveness in Spontaneously Breathing Patients With Sepsis, Acute Circulatory Failure, and Irregular Cardiac Rhythm
Diagnostic Accuracy of the Inferior Vena Cava Collapsibility to Predict Fluid Responsiveness in Spontaneously Breathing Patients With Sepsis, Acute Circulatory Failure, and Irregular Cardiac Rhythm
Objectives: To investigate whether respiratory variations of inferior vena cava diameters (cIVC) predict fluid responsiveness in spontaneously breathing patients with septic acute circulatory failure and irregular heartbeats.
Design: Prospective, bicentric study, intensive care units.
Patients and measures: Spontaneously breathing patients with sepsis and clinical signs of acute circulatory failure are included. A positive response to fluid loading (FL) is defined as an increase of the stroke volume (SV) >10%. The investigators measured the minimum inspiratory and maximum expiratory diameters of the IVC (idIVC and edIVC) during standardized (st) and unstandardized (ns) breathing. The investigators calculated cIVCst and cIVCns before a 500ml-colloid FL.
Inclusion Criteria:
Adult patients of the intensive care units of the Lille university-hospital and of the Valencienne general hospital.
Age greater than or equal to 18.
Patient insured
Spontaneous breathing without ventilatory support or intubation or tracheotomy.
Irregular cardiac rhythm
Prescription by the physician in charge of the patients of a 500 mL volume expansion in less than 30 minutes.
Patients with sepsis with at least one sign of acute circulatory failure:
