<b><i>Background:</i></b> Based on the pathophysiology of acute kidney injury (AKI), it is plausible that certain early interventions by the nephrologist could influence its trajectory. In this study, we investigated the impact of 5 early nephrology interventions on starting kidney replacement therapy (KRT), AKI progression, and death. <b><i>Methods:</i></b> In a prospective cohort at the Hospital Civil of Guadalajara, we followed up for 10 days AKI patients in whom a nephrology consultation was requested. We analyzed 5 early interventions of the nephrology team (fluid adjustment, nephrotoxic withdrawal, antibiotic dose adjustment, nutritional adjustment, and removal of hyperchloremic solutions) after the propensity score and multivariate analysis for the risk of starting KRT (primary objective), AKI progression to stage 3, and death (secondary objectives). <b><i>Results:</i></b> From 2017 to 2020, we analyzed 288 AKI patients. The mean age was 55.3 years, 60.7% were male, AKI KDIGO stage 3 was present in 50.5% of them, sepsis was the main etiology 50.3%, and 72 (25%) patients started KRT. The overall survival was 84.4%. Fluid adjustment was the only intervention associated with a decreased risk for starting KRT (odds ratio [OR]: 0.58, 95% confidence interval [CI]: 0.48–0.70, and <i>p</i> ≤ 0.001) and AKI progression to stage 3 (OR: 0.59, 95% CI: 0.49–0.71, and <i>p</i> ≤ 0.001). Receiving vasopressors and KRT were associated with mortality. None of the interventions studied was associated with reducing the risk of death. <b><i>Conclusions:</i></b> In this prospective cohort study of AKI patients, we found for the first time that early nephrologist intervention and fluid prescription adjustment were associated with lower risk of starting KRT and progression to AKI stage 3.

Fluid adjustment was the only intervention associated with a decreased risk for starting KRT (OR 0.58, 95% CI 0.48-0.70, p = &lt;0.001) and AKI progression to stage 3 (OR 0.59, 95% CI 0.49-0.71, p = &lt;0.001). Receiving vasopressors and KRT were associated with mortality, but neither of these interventions reduced these risks. Conclusion In this prospective cohort study of AKI patients, we found for the first time that early nephrologist intervention and fluid prescription adjustment was associated with a reduction in the risk of starting KRT and progression to AKI stage 3.

Abstract Introduction: Kidneys play a primary role in electrolyte homeostasis. The association between serum sodium level and mortality or the need for kidney replacement therapy during acute kidney injury has not been adequately explored. Methods: In this prospective cohort study, we enrolled patients admitted to the Civil Hospital of Guadalajara from August 2017 to March 2020. We divided patients into five groups based on the serum sodium level trajectories up to ten days following hospitalization, 1) stable normonatremia (serum sodium 135 and 145 mEq/L), 2) fluctuating serum sodium levels (increased/decreased in and out of normonatremia), 3) uncorrected hyponatremia, 4) corrected hyponatremia, and 5) uncorrected hypernatremia. We assessed the association of serum sodium trajectories with mortality and the need for kidney replacement therapy (secondary objective). Results: A total of 288 patients were included. The mean age was 55±18 years, and 175 (60.7%) were male. Acute kidney injury stage 3 was present in 145 (51%). Kidney replacement therapy started in 72 (25%) patients, and 45 (15.6%) died. After adjusting for confounders, 10-day hospital mortality was significantly higher in group 5 (HR, 3.12; 95% CI, 1.05 to 9.24, p = 0.03), and kidney replacement therapy initiation was higher in group 3 (HR, 2.44; 95% CI, 1.04 to 5.70, p = 0.03) compared with group 1. Conclusion: In our prospective cohort, most patients with acute kidney injury had alterations in serum sodium. Uncorrected hypernatremia was associated with death, and uncorrected hyponatremia was correlated with the need for kidney replacement therapy.

The Impact

Renal replacement therapy (RRT) can be used to support patient’s kidney function in cases of acute kidney injury (AKI). However, timing, modality, and dosing of RRT continue to remain in question. Recent studies have begun to provide data to help guide clinicians on when to initiate RRT, what form of RRT to use ranging from continuous venovenous hemofiltration (VVH) to intermittent hemodialysis, and the impact of high versus low-intensity dosing. Additionally, the risks associated with temporary vascular access with regard to thrombosis and infection, the impact of high efficiency and flux versus low efficiency and flux membranes, and options for anticoagulation in RRT for AKI are also discussed. This review contains 75 references.  Key words: acute kidney injury, chronic kidney disease, continuous venovenous hemofiltration, continuous venovenous hemodialysis, renal replacement therapy, venovenous hemofiltration,

Abstract Background Fluid overload, a critical consequence of acute kidney injury (AKI), is associated with worse outcomes. The optimal fluid removal rate per day during continuous renal replacement therapy (CRRT) is unknown. The purpose of this study is to evaluate the impact of the ultrafiltration rate on mortality in critically ill patients with AKI receiving CRRT. Methods This was a retrospective cohort study where we reviewed 1398 patients with AKI who received CRRT between December 2006 and November 2015 at the Mayo Clinic, Rochester, MN, USA. The net ultrafiltration rate (UFNET) was categorized into low- and high-intensity groups (&lt;35 and ≥35 mL/kg/day, respectively). The impact of different UFNET intensities on 30-day mortality was assessed using logistic regression after adjusting for age, sex, body mass index, fluid balance from intensive care unit (ICU) admission to CRRT initiation, Acute Physiologic Assessment and Chronic Health Evaluation III and sequential organ failure assessment scores, baseline serum creatinine, ICU day at CRRT initiation, Charlson comorbidity index, CRRT duration and need of mechanical ventilation. Results The mean ± SD age was 62 ± 15 years, and 827 (59%) were male. There were 696 patients (49.7%) in the low- and 702 (50.2%) in the high-intensity group. Thirty-day mortality was 755 (54%). There were 420 (60%) deaths in the low-, and 335 (48%) in the high-intensity group (P &lt; 0.001). UFNET ≥35 mL/kg/day remained independently associated with lower 30-day mortality (adjusted odds ratio = 0.47, 95% confidence interval 0.37–0.59; P &lt; 0.001) compared with &lt;35 mL/kg/day. Conclusions More intensive fluid removal, UFNET ≥35 mL/kg/day, among AKI patients receiving CRRT is associated with lower mortality. Future prospective studies are required to confirm this finding.

The Impact

Post-traumatic fluid management is a widely debated topic. No best-practice consensus exists. Adverse outcomes such as acute kidney injury or volume overload are common. Continuous renal replacement therapy (CRRT) is an adjunct therapy for severe acute renal failure and volume overload, but is costly and not without risk. Hemodynamic transesophageal echocardiography (hTEE) is widely accepted as a reliable way to monitor volume status of intensive care unit (ICU) patients. Although data exist evaluating hTEE and CRRT independently, there is a lack of research mutually inclusive of the two. We hypothesized that the use of hTEE is associated with less need for CRRT. Retrospective review of a level I trauma center from 2009 to 2015 identified patients that required CRRT. In 2013, we implemented a protocol using hTEE in trauma patients with significant resuscitation needs. We compared CRRTuse before and after implementation of the protocol (pre- and post-hTEE). Multivariate analysis using two sample t tests and χ2 test of the odds ratio (O.R.) was completed on variables such as injury severity score (ISS), acute kidney injury network (AKIN), days of CRRT, ICU length of stay (LOS), and hospital LOS. A total of 5037 and 6699 trauma patients were evaluated in the pre- and post-hTEE groups, respectively. Mean ISS was 22 and 28 for pre- and post-hTEE, respectively (P value 0.19). Mean AKIN was 2.7 for both groups. Mean days on CRRT was eight before hTEE and seven after hTEE (P value 0.7); 23 patients required CRRT pre-hTEE, and 15 required CRRT post-hTEE (P value 0.01 O.R. 2.4). Given, the odds of CRRT pre-hTEE are more than twice that of CRRT post-hTEE; we conclude that the use of hTEE is associated with a reduction of CRRT.

The Impact

Resuscitation of critically ill trauma patients can be precarious, and errors can cause acute kidney injuries. If renal failure develops, continuous renal replacement therapy (CRRT) may be necessary, but adds expense. Hemodynamic transesophageal echocardiography (hTEE) provides objective data to guide resuscitation. We hypothesized that hTEE use improved acute kidney injury (AKI) management, reserved CRRT use for more severe AKIs, and decreased cost and resource utilization. We retrospectively reviewed 2413 trauma patients admitted to a Level I trauma center's ICU between 2009 and 2015. Twenty-three patients required CRRT before standard hTEE use and 11 required CRRTafter; these are the “CRRT” and “CRRT/hTEE” groups, respectively. The hTEE group comprised 83 patients evaluated with hTEE, with AKI managed without CRRT. We compared the average creatinine, change in creatinine, and Acute Kidney Injury Network (AKIN) of “CRRT” with “CRRT/hTEE” and “hTEE.” We also analyzed several quality measures including ICU length of stay and cost. “CRRT” had a lower AKIN score (1.6) than “CRRT/hTEE” (2.9) ( P = 0.0003). “hTEE” had an AKIN score of 2.1 ( P = 0.0387). “CRRT” also had increased ICU days (25.1) compared with “CRRT/hTEE” (20.2) ( P = 0.014) and “hTEE” (16.8) ( P = 0.003). “CRRT” accrued on average $198,695.81 per patient compared with “CRRT/ hTEE” ($167,534.19) and “hTEE” ($53,929.01). hTEE provides valuable information to tailor resuscitation. At our institution, hTEE utilization reserved CRRT for worse AKIs and decreased hospital costs.
