Abstract:
Neurologic abnormality after cardiac surgery is common, and neurologic complications after cardiac surgery are among the most devastating problems that can occur in the postoperative period. Disruption of the blood-brain barrier (BBB) plays an important role in these complications. Assessment of the BBB integrity relies on cognitive testing, MRI, and measurement of brain biomarkers. In applying these methods, up to 50% of cardiac patients show some degree of BBB disruption and most of these abnormalities are short lived. To date there is no single test or measure that can predict BBB disruption in cardiac surgery.

Physiological Barriers
The blood endothelial barrier is the most porous of these. It allows all small ionized, un-ionized, and lipophilic molecules to pass through the endothelial lining into the interstitial space...

Factors Affecting Drug Distribution: Physiological Barriers
The capillary endothelial barrier allows only smaller molecules below 600 Da (Daltons) to pass through. It also restricts drugs like heparin that are bound to blood components, limiting their movement within the bloodstream.
