RT Journal Article SR Electronic T1 The Influence of the Intravenous Catheter Composition on its Hemocompatibility JF PDA Journal of Pharmaceutical Science and Technology JO PDA J Pharm Sci Technol FD Parenteral Drug Association (PDA) SP 27 OP 30 VO 53 IS 1 A1 De Jesus Andreoli Pinto, Terezinha A1 De Freitas Ribeiro, Alberto YR 1999 UL http://journal.pda.org/content/53/1/27.abstract AB Varied kinds of raw materials have been used for intravenous catheter manufacturing, raising important questions related to their hemocompatibility. In order to evaluate the influence of these materials on the hemocompatibility, different catheters—made of polyurethane (PU) (Vianont® or Tecoflext®), polytetrafluorethylene (PTFE) or polyvinyl chloride (PVC)—employed in 129 hospitalized patients, were analysed in this study. The used methodology involved careful catheter removal from patients, followed by chemical fixation and scanning electron microscopic evaluation of the adhered biological material. The results indicate that, on a decreasing scale of performance, PTFE catheters show better hemocompatibility than PU and PVC ones.
