Clinical Trial Summary

ratio of the diameter of inferior vena cava to the diameter of the thoracic aorta (IVC / Ao) depends on the daily balance of fluids.

Description:

During the routine abdominal ultrasound, the basilar and abdominal aorta were measured using a Sparq Philips ultrasonograph with a convex probe set in abdominal mode. All measurements were performed in one patient by the same operator who were experienced and performed the appropriate course of ultrasonography. The IVC and abdominal aorta were visualized using a paramedian long-axis view via a subcostal approach according to the methodology described by the American Society of Echocardiography. Inferior vena cava width was assessed at an interval of approximately 1 cm distal from connection of the hepatic vein to the inferior vena cava. No significant changes were observed in the width of the inferior vena cava during various respiratory phases, because of the positive pressure ventilation. The widest value was always chosen for the data. The assessment of the width of the abdominal aorta was performed above arise of the celiac trunk, at the height of the vein of the lower vena cava. The width of the inferior vena cava and the abdominal aorta was assessed using transthoracic ultrasound for the following five days. Daily differences in the amount of fluid intake and lost was recorded. CVP measurement was performed.
