Reevaluation Of Systemic Early Neuromuscular Blockade

Not Recruiting

Trial ID: NCT02509078


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.

Inclusion Criteria

1. Age \> 18 years
2. Presence of all of the following conditions for \< 48 hours:

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:

1. Lack of informed consent
2. Continuous neuromuscular blockade at enrollment
3. Known pregnancy
4. Currently receiving ECMO therapy
5. Chronic respiratory failure defined as PaCO2 \> 60 mm Hg in the outpatient setting
6. Home mechanical ventilation (non-invasive ventilation or via tracheotomy) except for CPAP/BIPAP used solely for sleep-disordered breathing
7. Actual body weight exceeding 1 kg per centimeter of height
8. Severe chronic liver disease defined as a Child-Pugh score of 12-15 (Appendix A2)
9. Bone marrow transplantation within the last 1 year
10. Expected duration of mechanical ventilation of \< 48 hours
11. Decision to withhold life-sustaining treatment; except in those patients committed to full support except cardiopulmonary resuscitation if an actual cardiac arrest occurs
12. Moribund patient not expected to survive 24 hours; if CPR provided, assess for moribund status greater than 6 from CPR conclusion
13. Diffuse alveolar hemorrhage from vasculitis
14. Burns \> 70% total body surface
15. Unwillingness to utilize the ARDS Network 6 ml/kg IBW ventilation protocol
16. Previous hypersensitivity or anaphylactic reaction to cisatracurium
17. Neuromuscular conditions that may potentiate neuromuscular blockade and/or impair spontaneous ventilation (Appendix A2)
18. Neurologic conditions undergoing treatment for intracranial hypertension
19. Enrollment in an interventional ARDS trial with direct impact on neuromuscular blockade and PEEP
20. \>120 hours of mechanical ventilation
21. P/F \< 200 mmHg at the time of randomization (if available)
