Remote Ischemic Conditioning to Enhance Resuscitation (RICE) Pilot
In Brief
A clinical study evaluating Active Remote Ischemic Conditioning and Sham Remote Ischemic Conditioning for Cardiac Arrest. Completed, enrolled 30 participants across 1 site.
Detailed Summary
Following resuscitation from out-of-hospital cardiac arrest (OHCA), reperfusion injury can cause cell damage in the heart and brain. Remote ischemic conditioning (RIC) consists of intermittent application of a device such as a blood pressure cuff to a limb to induce non-lethal ischemia. Studies in animals with cardiac arrest as well as in humans with acute myocardial infarction suggest that RIC before or after restoration of blood flow may reduce injury to the heart and improve outcomes but this has not been proven in humans who have had OHCA. The RICE pilot study is a single-center study to assess the feasibility of application of RIC in the emergency department setting for patients transported to the hospital after resuscitation from OHCA.

Timeline
Interventions
A standard non-invasive blood pressure cuff (e.g., American Diagnostics Corporation, Hauppauge, NY but any one can be used off the shelf) and disposable plastic clamp (e.g.,Medline Industries Incorporated, Mundelein, IL) can be used to apply RIC in patients resuscitated from OHCA via three cycles of 5-mins. inflation to 200 mmHg followed by 5-mins. deflation of a blood pressure cuff on a upper extremity. The cuff occludes the artery; the clamp maintains pressure in the air bladder of the cuff during the inflation periods.
The control group will have a sham package opened at the bedside as soon as feasible after ED arrival. This will be identical in size, weight and appearance as that in the intervention group, but will contain a sham device. Upon identification that the patient has been randomized to the control group, the care team will proceed with all other resuscitative measures as in the the intervention group.
