Acute kidney injury complicates over 50% of critical care admissions and is associated with both increased short and long-term mortality and the development or acceleration of chronic kidney disease. While in certain settings, such as cardiac surgery, primary prevention of AKI is possible, in most cases AKI is present or evolving at intensive care unit admission and the main clinical focus is secondary prevention of further kidney injury. In the absence of evidence for specific AKI-targeted therapies, high quality supportive care to maximize hemodynamic stability and avoidance of secondary sources of kidney injury are the cornerstones of renal protection. Fluid overload is particularly associated with adverse outcomes in critical illness complicated by AKI. Continuous methods of renal replacement therapy may promote hemodynamic stability and have been associated with better longer term renal outcomes.

AbstractPostoperative acute kidney injury (PO-AKI) is a common complication of major surgery that is strongly associated with short-term surgical complications and long-term adverse outcomes, including increased risk of chronic kidney disease, cardiovascular events and death. Risk factors for PO-AKI include older age and comorbid diseases such as chronic kidney disease and diabetes mellitus. PO-AKI is best defined as AKI occurring within 7 days of an operative intervention using the Kidney Disease Improving Global Outcomes (KDIGO) definition of AKI; however, additional prognostic information may be gained from detailed clinical assessment and other diagnostic investigations in the form of a focused kidney health assessment (KHA). Prevention of PO-AKI is largely based on identification of high baseline risk, monitoring and reduction of nephrotoxic insults, whereas treatment involves the application of a bundle of interventions to avoid secondary kidney injury and mitigate the severity of AKI. As PO-AKI is strongly associated with long-term adverse outcomes, some form of follow-up KHA is essential; however, the form and location of this will be dictated by the nature and severity of the AKI. In this Consensus Statement, we provide graded recommendations for AKI after non-cardiac surgery and highlight priorities for future research.

Acute kidney injury is strongly associated with increased mortality and other adverse outcomes. Medical researchers have intensively investigated novel biomarkers to predict short- and long-term outcomes of acute kidney injury in many patient care settings, such as cardiac surgery, intensive care units, heart failure, and transplant. Future research should focus on leveraging this relationship to improve enrollment for clinical trials of acute kidney injury.

AbstractDelirium is associated with significant negative outcomes, yet it remains underdiagnosed in children. We describe the impact of implementing a pain, agitation, and delirium (PAD) bundle on the rate of delirium detection in a pediatric intensive care unit (PICU). This represents a single-center, pre-/post-intervention retrospective and prospective cohort study. The study was conducted at a PICU in a quaternary university-affiliated pediatric hospital. All patients consecutively admitted to the PICU in October and November 2017 and 2018. Purpose of the study was describe the impact of the implementation of a PAD bundle. The rate of delirium detection and the utilization of sedative and analgesics in the pre- and post-implementation phases were measured. A total of 176 and 138 patients were admitted during the pre- and post-implementation phases, respectively. Of them, 7 (4%) and 44 (31.9%) were diagnosed with delirium (p < 0.001). Delirium was diagnosed in the first 48 hours of PICU admission and lasted for a median of 2 days (interquartile range [IQR]: 2–4). Delirium diagnosis was higher in patients receiving invasive ventilation (p < 0.001). Compliance with the PAD bundle scoring was 79% for the delirium scale. Score results were discussed during medical rounds for 68% of the patients in the post-implementation period. The number of patients who received opioids and benzodiazepines and the cumulative doses were not statistically different between the two cohorts. More patients received dexmedetomidine and the cumulative daily dose was higher in the post-implementation period (p < 0.001). The implementation of a PAD bundle in a PICU was associated with an increased recognition of delirium diagnosis. Further studies are needed to evaluate the impact of this increased diagnostic rate on short- and long-term outcomes.

Abstract Background and Aims Acute renal failure (AKI) associated to rhabdomyolysis conditions a worse prognosis in short-term, its implication in the long-term renal function has been less evaluated. Method Retrospective analysis of patients diagnosed with rhabdomyolysis defined by creatinine kinase &gt; 5000 IU/L between 2015-2019. Basal and 12-month renal function was evaluated. AKI was classified as either non-severe (AKI-KDIGO 1/2) or severe (AKI-KDIGO 3). Results Eighty-seven patients were included, 25 (28.74%) had some degree of chronic kidney disease (CKD) on admission. 56 (64.37%) had AKI on admission, 17 of which were severe (6 required hemodialysis). The patients with AKI had more cardiovascular disease (CVD) and worse analytical parameters on admission (table). Patients with severe AKI showed no difference in CVD from those with non-severe AKI but were younger and had more hyperkalemia. There were no significant differences between patients with severe AKI who required hemodialysis and those who did not. Inpatient mortality was 8%, higher in patients with AKI but without differences according to severity. In 45 patients kidney function was available 12 months after the episode, loss of eGF was -4.90 ± 14.35 ml/min-1.73m2 (p=0.007). There was no difference between patients who developed AKI and those who did not (-4.10 ± 14.4 vs. -5.39 ± 14.57 ml/min-1.73m2; p=0.67), nor between non-severe and severe AKI (-5.50 ± 14.76 vs. -5.12 ± 15.08ml/min-1.73m2; p=0.98). Of the 33 patients without previous CKD, 5 developed CKD, with greater decrease in eGF than those who did not (-22.69 ± 6.04 vs. -2.63 ± 13.92 ml/min-1.73m2; p=0.003). Female sex (60% vs. 12%; p=0.031) and previous basal eGF (72.22 ± 4.37 vs. 95.6±19.97 ml/min-1.72m2; p=0.016) were related to this deterioration. Conclusion After an episode of rhabdomyolysis, the loss of eGF is similar in patients who develop AKI compared to those who do not.

Contrast-induced acute kidney injury (CI-AKI) is characterised by a rapid deterioration of renal function within a few days of parenteral administration of contrast media (CM) in the absence of alternative causes. CI-AKI is the most common form of iatrogenic kidney dysfunction with an estimated prevalence of 12 % in patients undergoing percutaneous coronary intervention. Although usually selfresolving, in patients with pre-existing chronic kidney disease (CKD) or concomitant risk factors for renal damage, CI-AKI is associated with increased short- and long-term morbidity and mortality. Therefore, risk stratification based on clinical and peri-procedural characteristics is crucial in selecting patients at risk of CI-AKI who would benefit the most from implementation of preventive measures.

Patients with end-stage renal disease (ESRD) experience higher rates of hospitalisation, cardiovascular events, and all-cause mortality and are more likely to require admission to the intensive care unit (ICU) than patients with normal renal function. Sepsis and cardiovascular diseases are the most common reasons for ICU admission. ICU mortality rates in patients requiring chronic hemodialysis are significantly higher than for patients without ESRD; however, dialysis patients have a better ICU outcome than those with acute kidney injury (AKI) requiring renal replacement therapy suggesting that factors other than loss of renal function contribute to their prognosis. Current evidence suggests, the longer-term outcomes after discharge from ICU may be favourable and that long-term dependence on dialysis should not prejudice against prompt referral or admission to ICU.
