Secondary end points included any myocardial ischemia, respiratory and early procedural complications, acute kidney injury (AKI) according to RIFLE criteria (Risk, Injury, Failure, Loss of kidney function, and End-stage renal failure), spinal cord ischemia, a composite of these complications, and postoperative intensive care unit length of stay.
The novel RIFLE (pediatric RIFLE for pediatrics), Acute Kidney Injury Network (AKIN) and Kidney Disease Improving Global Outcomes (KDIGO) criteria have brought about unified diagnostic standards and comparable results for AKI after cardiac surgery.
Critically ill patients at risk of AKI and admitted to a general intensive care unit were categorised after initial resuscitation according to the RIFLE criteria for AKI.
The main outcomes were severe infusion-related adverse events according to the Common Terminology Criteria for Adverse Events and the renal failure category of RIFLE criteria for acute kidney injury (AKI) during treatment.
Acute renal failure (ARF) was defined as an increment of serum creatinine 3 times greater than baseline and/or at least 75% reduction in baseline eGFR as per RIFLE Classification.
Studies of adult major trauma patients admitted to critical care that applied consensus AKI criteria (risk injury failure loss end stage [RIFLE], AKI network, or kidney disease improving global outcomes) and reported clinical outcomes were assessed (PROSPERO Registration: CRD42017056781).
Three hundred thirty nine patients were included; AKI developed in 141 (41.6%) patients; RISK in 27 (8%) patients; INJURY in 25 (7%); FAILURE in 89 (26%) by the RIFLE criteria.
A literature search was performed using MEDLINE, EMBASE and Cochrane Database from inception until July 2018 to identify studies assessing the incidence of AKI (using standard AKI definitions of RIFLE, AKIN, and KDIGO classifications) in patients undergoing THA.
Urine output criteria detected AKI in patients without AKI at ICU admission in a median of 13 h (IQR 7-22 h; using RIFLE definition) after admission compared to a median of 24 h using serum creatinine criteria (IQR24-48 h).
There was no difference in survival between patients experiencing AKI according to the RIFLE or AKIN criteria without RRT requirement and patients without AKI.
End points included post-operative death; acute kidney injury (AKI) defined by the RIFLE (Risk, Injury, Failure, Loss of function, End stage renal disease) criteria; and long term follow-up with freedom from chronic renal decline (CRD) and any graft related complications.
This study evaluated the incidence, predictors and prognosis of AKI associated with scrub typhus according to the RIFLE (risk, injury, failure, loss, end-stage kidney disease) criteria.
Multivariate logistic regression was used to determine the best predictive models for AKI (RIFLE [renal Risk, Injury, Failure, Loss of renal function and End-stage renal disease] classification), incremental predictive value of minimum cardiopulmonary bypass DO<sub>2</sub>i, and optimal threshold.
AKI was defined according to the RIFLE criteria (risk, injury, failure, loss of kidney function, and end-stage kidney disease): increase by 50% in sCr or reduction of at least 25% of estimated glomerular filtration rate (eGFR) from baseline.
Group I also manifested significantly higher incidence of AKI than group II (62.7% vs. 28.5%, p = 0.005), even when stratified according to RIFLE criteria ('Risk' 33.9% vs. 10.7%; 'Injury' 10.2% vs. 8.9%; 'Failure' 18.6% vs. 8.9%; p = 0.03).
