Association Between Renal Resistive Index(RRI) and AKI(Acute Kidney Injury) in Cardiac Surgery Patients With Cardiopulmonary Bypass (CPB)

NCT06464666 · Status: NOT_YET_RECRUITING · Type: OBSERVATIONAL · Enrollment: 250

Summary

AKI(Acute Kidney Injury) is a common complication after cardiac surgery which is associated with increased mortality and morbidity. The conventiional marker for detecting AKI is serum creatinine, however, which has many limits. RRI(Renal Resistive Index) is a non-invasive test measured by ultrasound and could be a useful tool to evaulate renal insult in the early phase. Early detection of renal insult and prevention of progression to AKI can contribute to reduing mortality and morbidity in cardiac surgical patients.

Conditions

Interventions

PROCEDURE

Renal interlobar artery US

By using convex US transducer, first find interlobar artery. Then get a pulsed wave doppler at renal interlobar artery for similar 3 to 5 waveforms. Measure peak systolic and minimum diastolic velocity and calculate RRI value.

PROCEDURE

Renal inter-lobular artery US

By using convex US transducer, first find interlobar artery. Then get a pulsed wave doppler at renal interlobar artery for similar 3 to 5 waveforms. Measure peak systolic and minimum diastolic velocity and calculate RRI value.
