To determine whether respiratory variation in inferior vena cava diameter accurately predicts fluid responsiveness in clinical decision-making.
Evaluated the diagnostic utility of respiratory-induced changes in inferior vena cava caliber measured via point-of-care ultrasound.
Assessed test performance and diagnostic accuracy across patient populations, focusing specifically on spontaneously ventilating patients.
Respiratory variation in inferior vena cava diameter demonstrated limited diagnostic accuracy for predicting fluid responsiveness, with particularly reduced utility in spontaneously breathing patients.
A negative ultrasound evaluation demonstrated inadequate sensitivity to rule out fluid responsiveness, establishing that treatment decisions require broader clinical context.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Diagnostic evaluation demonstrates limited accuracy of IVC variation in spontaneously ventilating patients, indicating ultrasound cannot rule out fluid responsiveness.
