Office of Naval Research Contract N00014-94-c-0149 Technical Report 97-03 Effects of Cardiopulmonary Bypass on Hemostasis

Office of Naval Research Contract N00014-88-c-0118 Contract N00014-94-c-0149 Technical Report 95-07 the Effect of Heparin on Fibrinolytic Activity and Platelet Function

Heparin, a polyanionic glycosaminoglycan, is used routinely prior to the induction of cardiopulmonary bypass. Earlier observations in our laboratory suggested that the postoperative bleeding which occurs, despite neutralization of heparin with prdtamine, is secondary to hypothermia and dilutional anemia during bypass. An additional, potential mechanism for excessive bleeding following cardiopul...

Office of Naval Research Contract N00014-94-c-0149 Technical Report 97-07 the Effects of Aspirin and Hypothermia on Platelet Function in Vivo By

Patients undergoing hypothermic cardiopulmonary bypass are often on aspirin therapy. Hypothermia, aspirin, and cardiopulmonary bypass can each induce a platelet function defect, but it is not known if the effects of aspirin and hypothermia are additive in this regard. To address this question in humans in vivo, the forearm skin temperature of healthy volunteers was equilibrated and maintained a...

Office of Naval Research Contract N00014-88-c-0118 Contract N00014-94-c-0149 Technical Report 95-01 Bleeding Time, Volume of Shed Blood Collected at the Bleeding Time Site, and the Peripheral Venous Hematocrit

BACKGROUND: The relation between the bleeding time, the peripheral veous hematocirt and the amount of blood shed at the template bleeding time site has not been previously defined. METHODS; We studied this relation in 227 individuals: 26 were performed on patients with ITP, 137 on patients with a variety of other bleeding disorders, and 64 in normal subjects. Bleeding times were performed by a ...

Direct Estimation of Motion and Extended Scene Structure from a Moving Stereo Rig

We describe a new method for motion estimation and 3D reconstruction from stereo image sequences obtained by a stereo rig moving through a rigid world. We show that given two stereo pairs, one can compute the motion of the stereo rig directly from the image derivatives (spatial and temporal). Correspondences are not required. One can then use the images from both pairs combined, to compute a de...
