Conditions
Acute Kidney Injury
Interventions
Registration Number
NCT06248359
Lead Sponsor
Xijing Hospital
Brief Summary

To investigate the association between the the early administration of L-Arginine after CPB-assisted cardiac surgery and the incidence of CS-AKI in adult patients. To test if it can reduce the incidence of post-operative AKI.

Primary Outcome Measures
NameTimeMethod
incidence of postoperative AKIfrom the time of end of surgery until time of documented hospital discharge or time of death, whichever came first, assessed up to 30 days

Serum Creatinine Criteria:

Increase in Serum Creatinine:

An absolute increase in serum creatinine of 0.3 mg/dL (26.5 µmol/L) within 48 hours.

OR a percentage increase in serum creatinine of ≥50% within 7 days. These criteria are relative to the baseline creatinine level, which is usually the recent preadmission value.

Urine Output Criteria:

Oliguria, defined as a urine output \<0.5 mL/kg/h for more than 6 hours. OR anuria, defined as a urine output \<100 mL in 24 hours.

Secondary Outcome Measures
NameTimeMethod
length of in-hospital stayfrom the time of end of surgery until time of documented hospital discharge or time of death, whichever came first, assessed up to 30 days

postoperative stay until discharge or death

Renal failurefrom the time of end of surgery until time of documented hospital discharge or time of death, whichever came first, assessed up to 30 days

KDIGO defined AKI stage ≥ 2, or if dialysis is required for newly developed conditions

KDIGO classifies AKI into three stages based on the severity:

Stage 2:

Increase in serum creatinine of 2.0 to 2.9 times baseline OR Urine output \<0.5 mL/kg/h for ≥12 hours.

Stage 3:

Increase in serum creatinine of 3.0 times baseline OR Increase in serum creatinine to ≥4.0 mg/dL OR Initiation of renal replacement therapy (RRT) OR Urine output \<0.3 mL/kg/h for ≥24 hours OR anuria for ≥12 hours.

in-hospital mortalityfrom the time of end of surgery until time of documented hospital discharge or time of death, whichever came first, assessed up to 30 days

all-cause postoperative deaths observed
