Infusion peripheral access devices

The tube consists of synthetic polymers such as fluotinated ethylene propylene (FEP) or polyurethane (PU). For infusion of viscous fluids such as blood and for rapid infusimi cannulas with diameters of 14—16 G have to be used. Smaller size diameters (18—24 G) of catheters are suitable for continuous and intermittent administration of parenteral solutions. Thorough management of the device (e.g. flushing, dressing, daily inspection) reduces complications (e.g. phlebitis) caused by a peripheral access. The need to replace the cannulas routinely is debated. 

In patients with CKD, preservation of the integrity of peripheral and central veins is of vital importance for future hemodialysis access. Avoid i.v. infusion or vein puncture in the forearm and upper arm veins at both arms whenever possible. Insertion of venous access devices carries the risk to injure the veins and thereby incite phlebitis, sclerosis, stenosis or thrombosis and has to be avoided. Whenever a central venous catheter is needed, catheterization of the internal jugular or femoral vein is always preferred. Use of subclavian vein should be... 

Catheter device selection is based on a number of factors, including the plarmed application and placement site, duration of implantation, composition of fluids infused, and frequency of access (Namyslowski and Patel, 1999). Vascular catheters can be divided into two genei groups shortterm, temporary catheters that are placed percutaneously, and long-term, indwelling vascular catheters that usually require a surgical insertion. Temporary catheters include short peripheral venous and arterial catheters, nontunneled central venous and arterial catheters, and peripherally inserted central catheters (Pearson, 1996). Tunneled central venous catheters and totally implantable intra-... 

A peripheral venous catheter or indwelling venous cannula (see Fig. 13.7) is the most commonly used vascular access. Often these infusion devices are named by their brand name such as Venflon marketed by BD or Brauniile marketed by B.Braun Melsungen. The cannula or peripheral venous catheter is inserted into a peripheral vein at the hand or the arm to administer infusion solutions...
