Review Meta Analysis
An Open Lung Strategy in the Management of Acute Respiratory Distress Syndrome: A systematic review and meta-analysis.
An open lung strategy (OLS) that includes positive end expiratory pressure and recruitment maneuvers during mechanical ventilation is probably an important treatment method in patients with acute respiratory distress syndrome (ARDS). However, the effect of OLS is unknown. We therefore hypothesized that patients with ARDS may benefit from OLS treatment. ⋯ Results from this systematic review and meta-analysis suggest that OLS during mechanical ventilation significantly reduces mortality among patients with ARDS.

Acute kidney injury (AKI) following exploratory laparotomy and temporary abdominal closure (TAC) is poorly understood but clinically significant. We hypothesized that the prevalence of AKI would be highest 96 h following TAC, early hypoxemia would predict AKI, and that AKI would be an independent predictor of mortality. ⋯ AKI is common following TAC, reaches greatest prevalence 48 h after initial laparotomy, and is associated with increased mortality. NPWT fluid loss is a risk factor for AKI that is unique to TAC patients.

The Model for End Stage Liver (MELD) score is validated to predict pretransplant mortality. However, as a predictor of postoperative outcomes, its utility has proven inconsistent. Recently developed MELD-Lactate models better predict 30-day survival as compared with the MELD and MELD-Sodium scores. ⋯ For in-hospital mortality, the original MELD-Lactate model had slightly higher c-statistic (0.739) compared with the Mount Sinai MELD-Lactate model (0.734). Despite the distribution differences in the MELD-Lactate models, the model validation results, both from cross-validation and bootstrap methods, were similar. Postoperative MELD-Lactate and isolated postoperative lactate values were moderately predictive of 30-day and in-hospital mortality following liver transplantation in this patient cohort.

Delayed antimicrobial therapy in sepsis is associated with increased hospital mortality, but the impact of antimicrobial timing on long-term outcomes is unknown. We tested the hypothesis that hourly delays to antimicrobial therapy are associated with 1-year mortality in pediatric severe sepsis. ⋯ Hourly delays to antimicrobial therapy, up to 3 h, were not associated with 1-year mortality in pediatric severe sepsis in this study. The finding that antimicrobial therapy ≤1 h from sepsis recognition was associated with increased 1-year mortality should be regarded as hypothesis-generating for future studies.

Crush syndrome (CS) is a serious medical condition characterized by muscle cell damage resulting from pressure. CS has a high mortality, even when patients receive fluid therapy. We examined whether administration of NaNO2-containing fluid can improve survival in a rat model of CS. ⋯ Treatment with 200 μmol/kg NaNO2 prevents muscle damage induced by ischemia reperfusion via the protective effects of NO and suppression of systemic inflammation, thereby increasing survival rates in CS.
