Central venous device infections are associated with increased physical and psychological morbidity, mortality, length of stay, and costs. The aim of this study was to prove the efficacy of pulsatile flushing to prevent the bacterial colonization of vascular access devices. One hundred and forty four tests using 576 polyurethane short venous access catheters were performed. Four catheters per t...

In this paper, we investigate mechanisms for improving the quality of communications in wirelessoptical broadband access networks (WOBAN), which present a promising solution to meet the growing needs for capacity of access networks. This is achieved by using multiple gateways and multi-channel operation along with a routing protocol that effectively reduces the effect of radio interference. We ...

Vascular access-site complications remain a major cause of morbidity and mortality with cardiac catheterization and percutaneous intervention using the femoral approach. Complications may be divided into major and minor. Major complications include bleeding that requires transfusion, retroperitoneal hemorrhage and nonhemorrhagic complications such as pseudoaneurysm, arteriovenous fistula, arter...
