Hydrocortisone Preserves the Vascular Barrier by Protecting the Endothelial Glycocalyx

Abstract

Hydrocortisone preserves the endothelial glycocalyx, sustaining the vascular barrier and reducing interstitial edema. The effect of colloids suggests that prevention of postischemic rise in coronary resistance by hydrocortisone could also be based on alleviation of endothelial swelling. Stabilization of myocardial mast cells by hydrocortisone may account for the mitigated inflammatory affect of ischemia-reperfusion.
