Venepuncture and cannulation: Indications and vein selection

Venepuncture is the process of puncturing a vein with a needle. Intravenous cannulation is the process of inserting a plastic tube into a peripheral vein in order to access the circulatory system. Both venepuncture and intravenous cannulation are extremely common in almost all healthcare settings.

Up to 80% of patients receive a peripheral venous access device during an in-hospital stay. Although historically a medical role, venepuncture and intravenous cannulation are now being carried out by a variety of healthcare professionals including nurses and midwives.
