Platelet response to regional and systemic shock.
Hemorrhage in dogs to 30 mm. Hg did not produce platelet aggregation. Significant platelet aggregation was shown in stored blood delivered through the standard blood administration set, in the splanchnic circulation in endotoxic shock, and in the inferior vena cava following three hours of aortic cross-clamping. Pulmonary trapping of platelet aggregates could not be shown by serial screen filtration pressure measurements.
