Design outcomes

Primary

Measure	Time frame
Renal Resistive index more than or equal to 0.74 indicates post operative development of acute kidney injury Acute renal injury will be defined as an abrupt (within 48 h) absolute increase in the serum creatinine concentration of =0.3 mg/dL from baseline, a percentage increase in serum creatinine of =50%, or oliguria of less than 0.5 mL/kg/hr for more than 6 hTimepoint: 48 hours after surgery	—

Secondary

Measure	Time frame
raise in central venous pressure along with renal resistive index more than or equal to 0.74 indicates postoperative development of acute renal injuryTimepoint: 48 hours after surgery	—
