Abstract

Background: The aim of this study was to evaluate the utility of collapsibility of the internal jugular veins (IJVs) and subclavian veins (SCVs) in comparison with collapsibility of the inferior vena cava (IVC) in patients receiving pressure support ventilation.

Methods: Patients receiving pressure support ventilation were prospectively enrolled when fluid bolus administration was clinically indicated. The antero-posterior diameters of IJVs, SCVs and IVC were measured. Fluid responsiveness was defined as an 8% increase in stroke volume calculated with arterial pulse contour analysis after a passive leg raising maneuver.

Results: Twenty-seven patients (34 measurements) were included. Eighteen measurements were deemed fluid responsive. The area under the receiver operating characteristic curve of collapsibility of the right IJV antero-posterior diameter was 0.88 (95% confidence interval (CI): 0.75 - 0.99), while the area under the ROC curves for the antero-posterior diameter of the left IJV, right SCV, left SCV and the IVC were 0.57 (95% CI: 0.37 - 0.77), 0.61 (95% CI: 0.41 - 0.80), 0.55 (95% CI: 0.35 - 0.76) and 0.57 (95% CI: 0.37 - 0.77), respectively.

Conclusions: These results suggest that collapsibility of the right IJV is a useful predictor of fluid responsiveness in patients receiving pressure support ventilation. Collapsibility of the IVC did not predict fluid responsiveness in these patients.
