Intravenous (IV) Cannulation
Currently no guidelines available.
Step by step
Prepare the following materials before inserting an intravenous fluid line:
– non-sterile gloves
– an intravenous catheter
– a tourniquet
– an infusion set
– a bag of intravenous fluid
– intravenous catheter dressing
– gauze swabs
– a sharps container
– a separate three-way tap which may be necessary if the intravenous catheter is not equipped with one
– an intravenous line stopper
– a vacutainer needle, in case blood samples need to be taken as well
– laboratory tubes
Gauge number and needle sizes
Take note that the lower the gauge number is, the bigger the needle. Sizes usually range from 24 gauge which is most commonly used in paediatrics, to 16 gauge mostly used in the intensintravenouse care unit or operating room. 18 is the most commonly used gauge; this size may be used to administer blood and also allows drugs to be administered quickly.
