Background: Early fluid expansion could prevent postoperative organ hypoperfusion. However, excessive fluid resuscitation adversely influences multiple organ systems. This retrospective, observational study aimed to investigate the relationship between early negative fluid balance and postoperative mortality in critically ill adult patients following cardiovascular surgery. Methods: In total, 567 critically ill patients who had undergone cardiovascular surgery and whose intensive care unit length of stay (LOS) was more than 24 hours were enrolled. The baseline characteristics, daily fluid balance and cumulative fluid balance were obtained. Patients were followed until discharge or day 28. Multivariate logistic regressions adjusted by propensity score were used to analyze the relationship between early negative fluid balance and postoperative mortality. Results: Overall, postoperative mortality was 6.2% (35/567). Acute Physiology and Chronic Health Evaluation II on admission (odd ratios [OR] 1.110), acute kidney injury stage (OR 1.639) and renal replacement therapy received (OR 3.922) were the independent risk factors of postoperative mortality, whereas negative daily fluid balance at day 2 (OR 0.411) was the protective factor. Patients with a negative daily fluid balance at day 2 had lower postoperative mortality (3.4% vs. 12.2% in the positive fluid balance group), lower acute kidney injury (AKI) stage, were less likely to receive renal replacement therapy (RRT) and experienced shorter hospital LOS compared with those with a daily positive fluid balance. Conclusion: This retrospective, observational study indicates that early negative fluid balance is associated with lower postoperative mortality in critically ill patients following cardiovascular surgery. Further prospective, randomized trials are needed to prove the benefits from the restrictive fluid management strategy.

ABSTRACT Acute kidney injury (AKI) occurs in a substantial proportion of critically ill patients receiving intravenous colistin. In the pharmacokinetic/toxicodynamic analysis reported here, the relationship of the occurrence of AKI to exposure to colistin and a number of potential patient factors was explored in 153 critically ill patients, none of whom were receiving renal replacement therapy. Tree-based modeling revealed that the rates of AKI were substantially higher when the average steady-state plasma colistin concentration was greater than ∼2 mg/liter.

Abstract Background and Aims Continuous renal replacement therapy (CRRT) is essential in treating critically ill patients with acute kidney injury, and circuit downtime is considered a quality indicator. However, it remains uncertain whether CRRT downtime affects outcomes such as mortality and renal recovery. This study investigated the impact of downtime on various clinical outcomes in critically ill patients undergoing CRRT. Method A total of 216 patients who underwent CRRT were retrospectively recruited. Downtime was calculated over 4 days from CRRT initiation, and patients were classified as downtime <20% or ≥20% of potential operative time. Patients with ≥20% downtime were matched to those with <20% downtime using 1:2 propensity score matching, adjusting for age, sex, comorbidity index, and severity score. Results There were 88 patients with <20% downtime and 44 patients with ≥20% downtime. The cumulative volume and median flow rate of effluent in patients with ≥20% downtime were lower than those in patients with <20% downtime (P<0.001 and 0.062, respectively). Daily fluid balance differed on days 2 and 3 (P=0.046 and 0.031, respectively), and the difference in levels of urea and creatinine widened over time (P=0.004 and <0.001, day 4). The levels of total carbon dioxide were lower in those with ≥20% downtime (P=0.038 and 0.020 at days 2 and 3). Based on our results, ≥20% downtime was not associated with increased 28-day mortality (P=0.944). On the other hand, a subgroup analysis showed the interaction between downtime and daily fluid balance on mortality (P=0.004). In this study, downtime was not related to renal recovery. Conclusion Increased downtime could impair fluid and uremic control and acidosis management in patients undergoing CRRT. Moreover, the adverse effect of downtime on fluid control may increase mortality rate. Further studies are needed to verify the value of downtime as a quality indicator and its impact on outcomes in critically ill patients requiring CRRT.

<b><i>Background and Objectives:</i></b> Acute kidney injury (AKI) is a common complication among patients with COVID-19 and acute respiratory distress syndrome. Reports suggest that COVID-19 confers a pro-thrombotic state, which presents challenges in maintaining hemofilter patency and delivering continuous renal replacement therapy (CRRT). We present our initial experience with CRRT in critically ill patients with COVID-19, emphasizing circuit patency and the association between fluid balance during CRRT and respiratory parameters. <b><i>Design, Setting, Participants, and Measurements:</i></b> Retrospective chart review of 32 consecutive patients with COVID-19 and AKI managed with continuous venovenous hemodiafiltration with regional citrate anticoagulation (CVVHDF-RCA) according to the University of Michigan protocol. Primary outcome was mean CRRT circuit life per patient during the first 7 days of CRRT. We used simple linear regression to assess the relationship between patient characteristics and filter life. We also explored the relationship between fluid balance on CRRT and respiratory parameters using repeated measures modeling. <b><i>Results:</i></b> Patients’ mean age was 54.8 years and majority were Black (75%). Comorbidities included hypertension (90.6%), obesity (70.9%) diabetes (56.2%), and chronic kidney disease (40.6%). Median CRRT circuit life was 53.5 [interquartile range 39.1–77.6] hours. There was no association between circuit life and inflammatory or pro-thrombotic laboratory values (ferritin <i>p</i> = 0.92, C-reactive protein <i>p</i> = 0.29, D-dimer <i>p</i> = 0.24), or with systemic anticoagulation (<i>p</i> = 0.37). Net daily fluid removal during the first 7 days of CRRT was not associated with daily (closest recorded values to 20:00) PaO<sub>2</sub>/FIO<sub>2</sub> ratio (<i>p</i> = 0.21) or positive end-expiratory pressure requirements (<i>p</i> = 0.47). <b><i>Conclusions:</i></b> We achieved adequate CRRT circuit life in COVID-19 patients using an established CVVHDF-RCA protocol. During the first 7 days of CRRT therapy, cumulative fluid balance was not associated with improvements in respiratory parameters, even after accounting for baseline fluid balance.

Background/Aims: Acute kidney injury (AKI) in critically ill patients is common, and continuous renal replacement therapy (CRRT) is a preferred mode of renal replacement therapy (RRT) in hemodynamically unstable patients. Prediction of clinical outcomes in patients on CRRT is challenging. We utilized several approaches to predict RRT-free survival (RRTFS) in critically ill patients with AKI requiring CRRT. Methods: We used the Medical Information Mart for Intensive Care (MIMIC-III) database to identify patients ≥18 years old with AKI on CRRT, after excluding patients who had ESRD on chronic dialysis, and kidney transplantation. We defined RRTFS as patients who were discharged alive and did not require RRT ≥7 days prior to hospital discharge. We utilized all available biomedical data up to CRRT initiation. We evaluated 7 approaches, including logistic regression (LR), random forest (RF), support vector machine (SVM), adaptive boosting (AdaBoost), extreme gradient boosting (XGBoost), multilayer perceptron (MLP), and MLP with long short-term memory (MLP + LSTM). We evaluated model performance by using area under the receiver operating characteristic (AUROC) curves. Results: Out of 684 patients with AKI on CRRT, 205 (30%) patients had RRTFS. The median age of patients was 63 years and their median Simplified Acute Physiology Score (SAPS) II was 67 (interquartile range 52–84). The MLP + LSTM showed the highest AUROC (95% CI) of 0.70 (0.67–0.73), followed by MLP 0.59 (0.54–0.64), LR 0.57 (0.52–0.62), SVM 0.51 (0.46–0.56), AdaBoost 0.51 (0.46–0.55), RF 0.44 (0.39–0.48), and XGBoost 0.43 (CI 0.38–0.47). Conclusions: A MLP + LSTM model outperformed other approaches for predicting RRTFS. Performance could be further improved by incorporating other data types.
