Peripheral intravenous catheters: considerations in theory and practice.

Inserting peripheral intravenous catheters is a clinical skill that is increasingly becoming part of nurses' remit because of a number of changes in the NHS, including a reduction in junior doctors' working hours and role development. To undertake this skill it is important that nurses receive the appropriate education and can provide evidence of training and competence. A hospital policy is essential to standardize practice and ensure an evidence base.

This article provides both the theoretical and practical knowledge to assist nurses who wish to include cannulation as part of their clinical remit.
