Daily Ards Research Analysis
Among today's ARDS-focused papers, a national cohort study found no outcome advantage with continuous rocuronium in moderate-to-severe ARDS, informing NMBA choice beyond cisatracurium. An ELSO registry analysis reported 72.3% survival to discharge for ECMO after lung transplant with increasing use and improving survival trends. A correction notice alerts readers to updates in a major comparative study of COVID-19 ARDS versus pre-COVID pneumonia ARDS.

Research Themes
- Neuromuscular blockade strategies in ARDS
- ECMO utilization and outcomes in post–lung transplant respiratory failure
- Post-publication corrections in ARDS epidemiology and ventilation management research
Selected Articles
1. Extracorporeal membrane oxygenation after lung transplant: An ELSO registry analysis.
In a 2010–2022 ELSO registry analysis of 1,966 adults receiving ECMO >24 hours after lung transplant, 72.3% survived to discharge. ECMO use increased over time with a trend toward improved survival, and higher annual center volume was identified as a predictor in adjusted models.
Impact: Provides contemporary, large-scale, multicenter outcomes for ECMO after lung transplant and highlights a potential volume–outcome relationship, informing program design and benchmarking.
Clinical Implications: Supports referral to experienced centers and informs expectations for survival after ECMO in post–lung transplant respiratory failure; may guide resource allocation and quality metrics.
Key Findings
- Among 1,966 ECMO runs >24 hours after lung transplant, 72.3% of patients survived to discharge.
- ECMO utilization increased steadily across 2010–2022, with a trend toward improving survival.
- Multivariable logistic regression identified center-level factors, including higher annual center volume (reported OR 0.97 in excerpt), as predictors of survival.
Methodological Strengths
- Large, international registry with multi-year coverage
- Multivariable modeling to identify predictors of survival
Limitations
- Observational registry design with potential residual confounding and selection bias
- Abstract excerpt is truncated; full list of predictors and effect sizes not available here
Future Directions: Define center-level best practices and minimum volume thresholds; link registry with granular clinical and ECMO configuration data to refine risk models.
2. Association Between Rocuronium Administration and Clinical Outcomes in Patients With Moderate-To-Severe Acute Respiratory Distress Syndrome: A Retrospective Cohort Study.
In a national retrospective cohort of 1,992 ICU patients with pneumonia and moderate-to-severe ARDS (respiratory SOFA ≥3), continuous rocuronium infusion was not associated with differences in in-hospital or ICU mortality, length of stay, or duration of mechanical ventilation. Findings support rocuronium as a feasible alternative NMBA without observed harm.
Impact: Addresses a clinically relevant gap regarding non-cisatracurium NMBA use in ARDS, providing real-world evidence to guide sedo-analgesia and ventilatory synchronization strategies.
Clinical Implications: Rocuronium may be used as a continuous NMBA option for ventilator management in moderate-to-severe ARDS without expectation of improved mortality; selection should consider patient-specific factors and warrants prospective evaluation.
Key Findings
- Among 1,992 eligible ICU patients with moderate-to-severe ARDS due to pneumonia, 124 (6.2%) received continuous rocuronium.
- No significant difference in in-hospital mortality (OR 0.70; 95% CI 0.42–1.19) or ICU mortality (OR 0.87; 95% CI 0.41–1.87) between exposure and comparison groups.
- No significant differences in hospital length of stay, ICU stay, or duration of mechanical ventilation based on adjusted models with generalized estimating equations.
Methodological Strengths
- Nationwide inpatient database with clearly defined inclusion criteria
- Multivariable regression using generalized estimating equations to account for clustering
Limitations
- Retrospective observational design with potential confounding by indication
- Small exposure group (n=124) and limited detail on dosing, timing, and sedation practices
Future Directions: Prospective trials comparing rocuronium vs. cisatracurium with protocolized sedation and ventilatory targets; subgroup analyses by ARDS severity and ventilator asynchrony.
3. Correction to: Epidemiology, ventilation management and outcomes of COVID-19 ARDS patients versus patients with ARDS due to pneumonia in the Pre-COVID era.
This is a correction notice for a comparative study on epidemiology, ventilation management, and outcomes of COVID-19 ARDS versus pre-COVID pneumonia-related ARDS. No abstract text is provided in the record.
Impact: Signals post-publication updates to a widely relevant ARDS comparison, maintaining scientific record integrity.
Clinical Implications: Clinicians and researchers should consult the correction alongside the original article to ensure accurate interpretation of methods and outcomes.
Key Findings
- This publication is a correction notice linked to a study comparing COVID-19 ARDS with pre-COVID pneumonia-related ARDS.
- The record provides no abstract and does not present new analyses or data in this notice.
- Readers are alerted that aspects of the original report have been corrected; specifics must be obtained from the correction text.
Methodological Strengths
