Venepuncture and Cannulation
Sharron Oulds
IV Specialist Practitioner
Aims of the session:
• To use existing knowledge to examine and demonstrate
procedure for:
-Cannulation
-Venepuncture
-Blood cultures
• To discuss aspects surrounding the procedures.
• To discuss the importance of documentation in terms of
monitoring and audit.
Introduction
• Products- Equipment used for each procedure, tips and
hints to enable efficient and practical use.
• Place- Vein selection for each procedure, discussion of
how to reduce complications.
• Paperwork- Discussion of essential documentation and
monitoring of national standards through audit.
Cannulation- Products
• Epic2 Guidelines (Pratt et al 2007)
• Disposable tourniquet
• Skin prep 70% alcohol
Asepsis- Why?
• MRSA and MSSA Bacteraemia

taking Blood Cultures
Contamination
• Contamination of blood cultures occurs frequently.
• From where?
• Implications
-Extended Hospital stay
-Unnecessary treatment
-Possibilities of resistance or sensitivity reactions
-Cost to both patient and trust

Points for practice
• Aseptic Non-Touch Technique- think key parts
• Hand decontamination
• Skin preparation
• Do Not re-palpate after cleaning site
• Documentation is essential
