The purpose of this study is to determine whether hydroxychloroquine decreases the relative leakage of the brain barrier after surgery.


Hydroxychloroquine will be administered preoperatively to 30 patients undergoing cardiac or noncardiac surgery. All patients will undergo magnetic resonance imaging (MRI) with gadolinium in the post-operative period before hospital discharge in order to assess blood brain barrier permeability.
