Effect of Randomization to Neuromuscular Blockade on Physical Functional Impairment and Recovery in ARDS

The proposed work will determine the effect of neuromuscular blockade on physical function and recovery in patients with ARDS. The investigators will conduct a prospective ancillary study at five PETAL clinical centers that will evaluate the neuromuscular structure and function of ROSE (Reevaluation of Systemic Early Neuromuscular Blockade) patients during and after critical illness, including in-person assessments at 6 months after hospital discharge. The investigators hypothesize that patients randomized to NMB will have an increase in ICU-acquired neuromuscular dysfunction during and after critical illness.
