What type of venous access can be used for plasmapheresis?
The clinical scenario, especially the possibility for long-term venous access, and the type of plasmapheresis being used are important factors to consider when deciding on peripheral or central venous access. A peripheral vein allows a maximum flow of up to about 50 to 90 mL/min, so a single venous access is adequate for intermittent centrifugation. Continuous centrifugation techniques require two venous access sites or a central venous catheter. If long-term (>1 to 2 weeks) plasmapheresis is planned, a central venous catheter is required.
