Document Summary
Devices that maintain open venous access for med admin. while allowing children to be free of iv tubing. Veins on the back of the hand are generally chosen as iv site. Scalp vein tubing is used and capped at the end with a specifically designed rubber stopper or commercial trap. Tubing filled with dilute solution of heparin or ns through rubber stopper and flushed again with solution q2-8h to keep it patent. Tubing and stopper firmly secured to the wrist and armboard taped in place- protects site from trauma. Those receiving long term home and who only need iv medications- not additional fluids are good candidates. Can also be used for frequent blood sampling is required. Venous access for long term iv therapy can be obtained using a catheter inserted into the vena cava just outside the right atrium, the catheter exits the chest just under the clavicle.
