Background:Survivors of acute respiratory distress syndrome (ARDS) report generalized weakness and reduced exercise tolerance up to two years following discharge from the intensive care unit (ICU). Persistent neuromuscular complications of ARDS may contribute to the functional disability observed in these patients.Methods:Sixteen ARDS survivors underwent comprehensive neurological evaluation and standardized electrodiagnostic testing 6 to 24 months after ICU discharge. Four of these patients agreed to open muscle biopsy.Results:Seven of sixteen patients had clinically significant focal compressive mononeuropathies. Electrodiagnostic testing failed to reveal any changes attributable to critical illness polyneuropathy or myopathy. All four muscle biopsies were abnormal, and although the pathological features were structurally non-specific, the presence of an acquired myopathy remains possible. Four patients had persistent mixed sensory complaints but had normal electrodiagnostic evaluation.Conclusions:The high frequency of mononeuropathies highlights the need for vigilance in daily ICU care. The findings also suggest that complaints of weakness and reduced exercise capacity in ARDS survivors may be related to combined effects of compressive neuropathies and generalized longstanding structural changes in muscle and may support an organic basis for longterm functional disability.

Abstract Background Duration of invasive mechanical ventilation (IMV) prior to extracorporeal membrane oxygenation (ECMO) affects outcome in acute respiratory distress syndrome (ARDS). In coronavirus disease 2019 (COVID-19) related ARDS, the role of pre-ECMO IMV duration is unclear. This single-centre, retrospective study included critically ill adults treated with ECMO due to severe COVID-19-related ARDS between 01/2020 and 05/2021. The primary objective was to determine whether duration of IMV prior to ECMO cannulation influenced ICU mortality. Results During the study period, 101 patients (mean age 56 [SD ± 10] years; 70 [69%] men; median RESP score 2 [IQR 1–4]) were treated with ECMO for COVID-19. Sixty patients (59%) survived to ICU discharge. Median ICU length of stay was 31 [IQR 20.7–51] days, median ECMO duration was 16.4 [IQR 8.7–27.7] days, and median time from intubation to ECMO start was 7.7 [IQR 3.6–12.5] days. Fifty-three (52%) patients had a pre-ECMO IMV duration of > 7 days. Pre-ECMO IMV duration had no effect on survival (p = 0.95). No significant difference in survival was found when patients with a pre-ECMO IMV duration of < 7 days (< 10 days) were compared to ≥ 7 days (≥ 10 days) (p = 0.59 and p = 1.0). Conclusions The role of prolonged pre-ECMO IMV duration as a contraindication for ECMO in patients with COVID-19-related ARDS should be scrutinised. Evaluation for ECMO should be assessed on an individual and patient-centred basis.

Objective: To investigate the contribution of acute respiratory distress syndrome (ARDS) in of itself to mortality among ventilated patients. Design and Setting: A longitudinal retrospective study of ventilated intensive care unit (ICU) patients. Patients: The analysis included patients ventilated for more than 48 hours. Patients were classified as having ARDS on admission (early-onset ARDS), late-onset ARDS (ARDS not present during the first 24 hours of admission), or no ARDS. Primary outcomes were mortality at 28 days, and secondary outcomes were 2-year mortality rate from ICU admission. Results: A total of 1411 ventilated patients were enrolled: 41% had ARDS on admission, 28.5% developed ARDS during their ICU stay, and 30.5% did not meet the ARDS criteria prior to ICU discharge or death. The non-ARDS group was used as the control. We also divided the cohort based on the severity of ARDS. After adjusting for covariates, mortality risk at 28 days was not significantly different among the different groups. Both early- and late-onset ARDS as well as the severity of ARDS were found to be significant risk factors for 2 years from ICU survival. Conclusion: Among patients who were ventilated on ICU admission, neither the presence, the severity, or the timing of ARDS contribute independently to the short-term mortality risk. However, acute respiratory distress syndrome does contribute significantly to 2-year mortality risk. This suggests that patients may not die acutely from ARDS itself but rather from the primary disease, and during the acute phase of ARDS, clinicians should focus on improving treatment strategies for the diseases that led to ARDS.
