This study evaluates whether giving a neuromuscular blocker (skeletal muscle relaxant) to a patient with acute respiratory distress syndrome will improve survival. Half of the patients will receive a neuromuscular blocker for two days and in the other half the use of neuromuscular blockers will be discouraged.

PRIMARY OBJECTIVE:
To assess the efficacy and safety of early neuromuscular blockade in reducing mortality and morbidity in patients with moderate-severe ARDS, in comparison to a control group with no routine early neuromuscular blockade (NMB).
PRIMARY HYPOTHESIS:
Early neuromuscular blockade will improve mortality prior to discharge home before day 90, in patients with moderate-severe ARDS.
The trial will accrue a maximum of 1408 patients. Patients will be recruited from the emergency departments, intensive care units and other acute care areas of the PETAL Network Clinical Centers and randomized to the active (NMB) or control. The overall strategy is to screen, consent, and enroll early, every newly intubated, acutely ill or post-operative, eligible patient at each site, using clinically obtained pulse oximetry and blood gases.
By preventing active expiration, and/or patient ventilator dyssynchrony, neuromuscular blockade may create a more homogenous distribution of airway pressures and tidal volumes, preventing barotrauma/volutrauma and "atelectrauma" resulting in less ventilator-induced lung injury.

Inclusion criteria
i. PaO2/FiO2 < 150 with PEEP >/= 8 cm H2O OR, if ABG not available, SaO2/FiO2 ratio that is equivalent to a PaO2/FiO2 < 150 with PEEP >/= 8 cm H2O , and a confirmatory SaO2/FiO2 ratio that is again equivalent 1-6 hours later
ii. Bilateral opacities not fully explained by effusions, lobar/lung collapse, or nodules.
iii. Respiratory failure not fully explained by cardiac failure or fluid overload; need objective assessment (e.g., echocardiography) to exclude hydrostatic edema if no risk factor present.
Patients must be enrolled within 48 hours of meeting inclusion criteria.
Exclusion criteria
Patients randomized to the early neuromuscular blockade arm will receive a cisatracurium besylate bolus of 15 mg, followed by a continuous infusion of 37.5 mg/hour for 48 hours. Patients randomized to the control arm will receive no protocol specified neuromuscular blockade.

Time frame: 90 days after randomization
The percentage of subjects alive at study day 90. Those subjects discharged home prior to day 90 were counted as alive at day 90.
Time frame: 28 days after randomization
Ventilator-free days is defined to be 28 days minus the duration of mechanical ventilation through day 28. Participants who do not survive to day 28 are assigned zero ventilator-free days.
Time frame: 28 days after randomization
SOFA (Sepsis-related Organ Failure Assessment) was used to determine criteria for an organ failure free day. Scores were based on four of the six SOFA organ categories: Coagulation, Liver, Cardiovascular, and Renal. Each category was scored 0-4; 0 being normal functioning and 4 being the most abnormal. A patient was considered failure free on each day alive with SOFA scores below 2 for all four organ systems.

Time frame: 28 days after randomization
ICU free days is defined as the number of days between randomization and day 28 in which the patient is in the ICU (for any part of a day).
Time frame: 28 days after randomization
Hospital free days are days alive post hospital discharge through day 28. Patients who die on or prior to day 28 are assigned zero hospital free days.
Time frame: 3 months after randomization
Assesses whether individual can living independently and assess a range of common functional activities, from walking and toileting to managing money and cooking meals. Data is a pooled estimates from patient survey and proxy survey. The total score is rated from 0 to 10 (MCID=1; 1 point=1 ADL); a higher score indicates having more difficulties in daily activities.
Time frame: 3 months after randomization
Using a standardized scale, do health reasons limit the person's ability to enjoy their life? Pooled estimates from patient survey and proxy survey were used. Utility index was computed from a lookup table according to EQ-5D-5L response profiles; utility index ranges from -0.11 to 1.00 (higher scores are better; 1.00 is perfect health), minimal clinically important difference (MCID) is 0.07
Time frame: 6 months after randomization
Does the patient have symptoms of anxiety and stress from their ICU stay? PTSS-14 is only asked at month 6 and month 12 in patient survey; total score is rated from 14 to 98 and a higher score indicates having more post-traumatic stress syndrome related symptoms. Participants with scores greater than or equal to 45 were reported.
Time frame: 3 months after randomization
How clearly can patient think and recall things? MoCA-Blind is only asked in patient survey; total score is rated from 0 to 30 and a higher score indicates better cognitive performance. Normal range: 26 or greater.
