Extension Device

Externalization of the Port-A-Cath for intermittent access refers to insertion of a non-coring needle luer-locked to an extension tubing with a cap or saline lock. An extension device is necessary for maintaining access to the port and it must be primed with normal saline prior to insertion of the needle. Once inserted it provides means for intermittent or continuous access. The principles for manipulation and heparinization of the extension tubing are similar to any central line (i.e. clamping or closing the saline lock between each action). Ensure all connections are luer locked together and taped to prevent accidental disconnection.
