Key areas where used

Method of use

Extension sets are connected to IV catheters to allow a larger distance between the patient and the fluid being administered which is often necessary due to the size and volume of equipment being used at any one time. Sets should be primed prior to connection with catheter, if it is being used for infusions, a syringe should be attached and the set primed before being connected to the patient. Once an IV catheter has been introduced, the male luer lock of the extension tubing can be inserted into the port at the distal end of the catheter, sometimes this connection is secured by twisting a locking collar over the luer connection (provided on the extension set). The other end of the extension tubing can then be accessed by a syringe or more commonly, connected up to a primary giving set or syringe drive for the administration of fluids and medication. Tube extensions with narrow bores are used for paediatrics and neonates because often a lower volume/flow rate is required for smaller patients.

Please note: this datacard refers to simple extension sets. For extension sets that include stopcocks, T adapters, double or triple lumen etc. please see individual datacards

Luer- compatible needle-free connectors should be incompatible with whichever non-luer neuraxial connectors are adopted in the Welsh NHS.
