Evaluation of ivc and ijv dimensions in prediction of fluid responsiveness in spontaneous breathing patients with septic shock

Prediction of fluid responsiveness (FR) is a critical step in management of patients with septic shock. Using ultrasound in detection of inferior vena cava (IVC) diameters and collapsibility is established in mechanically ventilated patients; however its use in spontaneous breathing patients is still controversial [1]. Few studies reported a correlation between internal jugular vein dimensions and central venous pressure (CVP) [2, 3] but no data are available about the use of IJV dimensions in detection of FR.
