چکیده
BACKGROUND Rapid, accurate, and reproducible assessment of intravascular volume status is crucial in order to predict the efficacy of volume expansion in septic patients. The aim of this study was to verify the feasibility and usefulness of the internal jugular vein collapsibility index (IJV-CI) as an adjunct to the inferior vena cava collapsibility index (IVC-CI) to predict fluid responsiveness in spontaneously-breathing patients with sepsis. METHODS Three stages of sonographic scanning were performed. Hemodynamic data were collected using the Ultrasonic Cardiac Output Monitor 1A system (Uscom, Ltd., Sydney, NSW, Australia) coupled with paired assessments of IVC-CI and IJV-CI at baseline, after passive leg raise (PLR), and again in semi-recumbent position. Fluid responsiveness was assessed according to changes in the cardiac index (CI) induced by PLR. Patients were retrospectively divided into 2 groups: fluid responder if an increase in CI (ΔCI) ≥15% was obtained after PLR maneuver, and non-responder if ΔCI was <15%. RESULTS Total of 132 paired scans of IJV and IVC were completed in 44 patients who presented with sepsis and who were not receiving mechanical ventilation (mean age: 54.6±16.1 years). Of these, 23 (52.2%) were considered to be responders. Responders had higher IJV-CI and IVC-CI before PLR maneuver than non-responders (p<0.001). IJV-CI of more than 36% before PLR maneuver had 78% sensitivity and 85% specificity to predict responder. Furthermore, less time was needed to measure venous diameters for IJV-CI (30 seconds) compared with IVC-CI (77.5 seconds; p<0.001). CONCLUSION IJV-CI is a precise, easily acquired, non-invasive parameter of fluid responsiveness in patients with sepsis who are not mechanically ventilated, and it appears to be a reasonable adjunct to IVC-CI.

Phlebectasia of Internal Jugular Vein- A Rare Differential Case of Neck Swelling With Review of Literature
Introduction: Internal jugular vein ectasia is a condition in which there is a dilatation of the internal jugular vein. A patient usually presents in the first decade with swelling in the neck, which aggravates in size while straining or coughing. This is a very rare condition and the chances of misdiagnosis are quite high. It is diagnosed by proper history taking, examination, and radiol...

OBJECTIVE To evaluate the correlation between central venous pressure (CVP) and inferior vena cava (IVC) diameters measured by ultrasonography (Ultrasound) in critically ill patients. METHODS Intubated critically ill patients were enrolled. The CVP values were measured using a U-tube manometer and were compared to the IVC diameters and collapsibility index, which were measured by bedside Ultr...
متن کاملLigation of the internal jugular vein increased regional cerebral oxygen saturation but decreased the bispectral index in a 72-year-old man: a case report
Regional cerebral oxygen saturation (rSO2) and the bispectral index (BIS) are used to detect cerebral perfusion abnormalities. However, whether rSO2 and BIS values change during ligation of the internal jugular vein (IJV) is unknown. We report a case in which BIS values were decreased, despite increased rSO2 during ligation of the IJV. A 72-year-old man was diagnosed with metastasis of renal ca...

Lemierre syndrome is caused by an infection in the oropharyngeal region with subsequent thrombophlebitis in the internal jugular vein. The thrombus from the thrombophlebitis can invade other vital organs, such as liver, lungs, or joints, resulting in secondary infection, which further exacerbates the fatal prognosis of this syndrome. Lemierre syndrome, also called postanginal sepsis or necrobac...
