An Intervention to Reduce Delirium After Cardiac Surgery

Remote ischemic preconditioning is exposure to a brief period ischemia to an area or limb that is not involved in surgery. This intervention is believed to reduce the incidence of cerebral (brain) ischemia during cardiac surgery.

The Delirium assessment consist of a validated psychiatric screening tool called the Confusion Assessment Method. We will use this tool to determine if patients have any confusion after surgery.
