Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To study the changes in the renal artery and renal vein with renal cortical and medullary microcirculatory blood flow in patients with sepsis; to study the relationship between renal arteriolar and renal vein with renal cortical and medullary microcirculatory blood flow and renal function; and to find the value of ultrasonographic assessment of renal blood flow indices for evaluating prognosis in patients with sepsis.
