中文摘要
翻译
中心静脉导管通常会刺激血管内凝血,有时会进展为闭塞性深静脉血栓形成。为了防止这种情况,我们探索了在硅胶导管上涂上一种新的抗凝血剂Lepirudin的可能性,因为它是一种蛋白质,具有自然吸附到聚合物表面的趋势。我们已经证明,吸附在硅胶上的来皮鲁丁保留了大部分的抗凝血酶活性,而且这种药物只被血浆蛋白部分取代。此外,来皮鲁丁从导管管腔扩散的速度比肝素慢。因此,它可能有效地减少与这些导管相关的血栓的发生率。这项工作现已完成并出版。
英文摘要
Central venous catheters typically stimulate intravascular coagulation, which occasionally progresses to occlusive deep vein thrombosis. In an attempt to prevent this, we have explored the possibility of coating silicone catheters with a new anticoagulant, lepirudin, which because it is a protein has a natural tendency to adsorb to polymeric surfaces. We have shown that lepirudin adsorbed to silicone retains much of its anti-thrombin activity and that the drug is only partially displaced by plasma proteins. Furthermore, lepirudin diffuses from the catheter lumen more slowly than heparin. Therefore, it may be effective in reducing the incidence of thrombosis associated with these catheters. This work has now been completed and published.
