The main purpose of this study is to evaluate if neuromuscular blockade improves lactate clearance (and preliminary secondary clinical outcome measures) as compared to usual care in post-cardiac arrest patients undergoing targeted temperature management.

Clinical Details

Official title: Neuromuscular Blockade for Post-Cardiac Arrest Care

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject)

Primary outcome: Lactate levels 24 hours after initiation of study drug

Secondary outcome:

Lactate change over time


Good neurological outcome

Length of intensive care unit (ICU) stay

Detailed description: Out-of-hospital cardiac arrest (OHCA) occurs in more than 300,000 patients in the United States each year with an estimated mortality of greater than 90%. Unfortunately, we currently have little to offer in terms of treatment other than supportive care for the post-cardiac arrest patient. Neuromuscular blockade (NMB) is sometimes utilized in post-arrest patients particularly for the prevention of shivering. However, usage of NMB remains controversial and current AHA recommendations are to minimize utilization. Recent prospective randomized trials in patients with acute respiratory distress syndrome suggest a mortality benefit from NMB and an excellent safety profile. Furthermore, observational trials in both sepsis and post-cardiac arrest show that the use of NMB is associated with improved survival. Given this, we hypothesize that continuous NMB will be beneficial in post-arrest patients. In order to test this hypothesis, we propose a multi-center, randomized, open-label, phase trial in post-CA patients comparing sustained NMB administration for 24 hours to standard of care after ROSC. We will enroll adult, comatose OHCA patients with return of spontaneous circulation and will utilize an already existing clinical trials network for the completion of the study. Patients will be randomized to receive either rocuronium (or cisatracurium) for 24 hours or to receive placebo with usual care. Previous data from our group has suggested that lactate levels in the post-arrest patient are a good surrogate marker for mortality. We have therefore chosen to utilize lactate levels at 24 hours as the primary endpoint for the current trial. Secondarily we will evaluate clinical endpoints including length of stay, in-hospital mortality, and good neurological outcome. We will perform at sub-study of inflammatory markers and oxygen consumption at certain sites depending on additional funding that is currently pending.
