title: In vitro inhibition of endotoxin induced platelet aggregation with hydrocortisone sodium succinate (Solu-Cortef).
abstract: Citrated canine platelet rich plasma stimulated with ADP, thrombin, collagen and E. coli endotoxin demonstrated platelet aggregation when measured with Payton aggregometer. Following incubation with hydrocortisone sodium succinate (Solu-Cortef) the same platelet rich plasma did not undergo platelet aggregation when stimulated by these agents. Solu-Cortef added to platelet rich plasma during ATP, thrombin, collagen and endotoxin stimulated platelet aggregation resulted in a reversal of the optical density suggesting deaggregation. These in vitro observations support the beneficial effects observed when steroids are administered in vivo to experimental or clinical shock.
