Randomized Controlled TrialThe impact of a lung-protective ventilation mode using transpulmonary driving pressure titrated positive end-expiratory pressure on the prognosis of patients with acute respiratory distress syndrome.
This study aimed to assess the impact of a lung-protective ventilation strategy utilizing transpulmonary driving pressure titrated positive end-expiratory pressure (PEEP) on the prognosis [mechanical ventilation duration, hospital stay, 28-day mortality rate and incidence of ventilator-associated pneumonia (VAP), survival outcome] of patients with Acute Respiratory Distress Syndrome (ARDS). ⋯ Lung-protective mechanical ventilation using transpulmonary driving pressure titrated PEEP effectively improves lung function, reduces mechanical ventilation duration and hospital stay, and enhances survival outcomes in patients with ARDS. However, further study is needed to facilitate the wider adoption of this approach.

Meta Analysis Comparative StudySurvival difference in patients treated with extracorporeal membrane oxygenation in COVID-19 vs. non-COVID ARDS: a systematic review and meta-analysis.
The COVID-19 pandemic has emphasized the need for effective management of severe acute respiratory distress syndrome (ARDS) using veno-venous extracorporeal membrane oxygenation (VV-ECMO). This meta-analysis aims to compare the effectiveness and outcomes of ECMO in patients with COVID-19 ARDS versus those with non-COVID ARDS, assessing its role in different respiratory virus infections. ⋯ ECMO serves as a vital intervention in severe ARDS, with differential effectiveness observed between COVID-19 and non-COVID patients. The study's findings underline the need for precise patient selection and tailored ECMO application across different viral etiologies. These insights are crucial for enhancing clinical strategies and resource allocation during ongoing and future pandemics.

Mechanical power in decelerating flow versus square flow ventilation in pediatric ARDS.
Mechanical power is a summary variable quantifying the risk of ventilator-induced lung injury. The original mechanical power equation was developed using square flow ventilation. However, most children are ventilated using decelerating flow. It is unclear whether mechanical power differs according to mode of flow delivery. This study compared mechanical power in children with acute respiratory distress syndrome who received both square and decelerating flow ventilation. ⋯ Mechanical power was marginally lower in square flow than in decelerating flow, although the clinical significance of this is unclear. Upward of 30% of mechanical power may go toward overcoming resistance, regardless of age. This is nearly three-fold greater resistance compared to what has been reported in adults.

Association Between Baseline Driving Pressure and Mortality in Very Old Patients with ARDS.
Rationale: Because of the effects of aging on the respiratory system, it is conceivable that the association between driving pressure and mortality depends on age. Objectives: We endeavored to evaluate whether the association between driving pressure and mortality of patients with acute respiratory distress syndrome (ARDS) varies across the adult lifespan, hypothesizing that it is stronger in older, including very old (⩾80 yr), patients. Methods: We performed a secondary analysis of individual patient-level data from seven ARDS Network and PETAL Network randomized controlled trials ("ARDSNet cohort"). ⋯ In both cohorts, a driving pressure threshold of 11 cm H2O was associated with mortality in very old patients. Conclusions: Data from randomized controlled trials with strict inclusion criteria suggest that the effect of driving pressure on the mortality of patients with ARDS may depend on age. These results may advocate for a personalized age-dependent mechanical ventilation approach.

The lactate-to-albumin ratio (LAR) has been confirmed to be an effective prognostic marker in sepsis, heart failure, and acute respiratory failure. However, the relationship between LAR and mortality in patients with acute respiratory distress syndrome (ARDS) remains unclear. We aim to evaluate the predictive value of LAR for ARDS patients. ⋯ We confirmed that there was a positive correlation between LAR and 28-day mortality. This could provide anesthesiologists and critical care physicians with a more convenient tool than SAPSII without being superior for detecting ARDS patients with poor prognosis timely.
