Bedside Renal Ultrasound Assessment in Critically Ill Patients With Acute Kidney Injury: an Observational Study

This study aims to perform bedside renal ultrasound examinations on critically ill patients admitted to the ICU (including sepsis, respiratory failure, shock, multiple trauma, etc.) and prospectively observe the relationship between ultrasound parameters and the occurrence and progression of AKI, in conjunction with traditional renal function indicators. This will provide clinicians with a rapid, non-invasive, and visual examination tool at the bedside for early diagnosis and treatment of AKI.
