1) Venepuncture

,INTRODUCTION
- Wash hands, introduce self and confirm patient’s name, DOB and H&C number
- Explain the procedure and gain consent
- Check for allergies, including chlorhexidane
- Ask their preferred arm (usually non-dominant) and avoid bruised, excoriated or areas with
arteriovenous fistulae.

PREPARATION
- Wash hands
- Clean equipment tray
- Gather equipment (gloves, tourniquet, skin cleansing wipe, butterfly needle, vacutainer
holder, required blood tubes, sterile gauze and tape).
- Attach vacutainer to butterfly needle
- Return to patient with tray and a sharps box




PROCEDURE
A) Vein identification
- Expose the arm and place a pillow underneath
- Place tourniquet around the patient’s arm 4-5 finger lengths
above the vein site (usually antecubital fossa)
- Identify a bouncy vein (not necessarily one you can see)
- Remove tourniquet

B) Venepuncture
- Wash hands
- Put on gloves
- Sterilise the area with a skin cleansing wipe
- Reapply tourniquet
- Anchor the vein with your non-dominant hand and insert the needle with the other hand at
an angle of 10-30 degrees, once flashback is observed you are in the correct position.
- Fill blood bottles in the correct order, inverting them after filling
- Remove the tourniquet after the last bottle
- Place gauze loosely over the puncture site whilst removing the needle
- Place needle into the sharps pain and secure the gauze with tape

TO COMPLETE
- Thank the patient
- Discard waste and clean the tray, then discard gloves and wash hands
- Attach patient stickers to bottles (opposite the fill line) and fill out request forms
- Document procedure
NB: Always take U+Es first to reduce risk of pseudo-hypokalaemia
2) Intravenous cannulation

,INTRODUCTION
- Wash hands, introduce self, confirm patient’s name, DOB and H&C number
- Explain procedure and gain consent
- Check for allergies including Chlorhexidane
- Ask preferred arm

PREPARATION
- Wash hands
- Clean tray
- Gather equipment (gloves, tourniquet, skin cleansing wipe, pink 20G cannula unless patient
needs urgent fluid resus, sterile gauze, cannula dressing, posi-flush, cannula IV extension set
and tape)
- Neatly place equipment in the tray ensuring it remains inside its packaging
- Prime cannula set: Don PPE, flush each lumen with 1ml of sterile saline and place set back
into its packets
- Don apron and wash hands
- Return to patient with tray and sharps bin




PROCEDURE
- Vein identification
- Wash hands and place on gloves
- Reapply tourniquet
- Anchor the skin distal to the vein with your non-dominant hand and insert the cannula at a
10-30 degree angle
- When you observe flashback, advance the tubing a further 2mm without moving the needle
- Hold the cannula in place with your dominant hand and place a square of gauze underneath,
using your non-dominant hand remove the needle of the cannula
- Attach the cannula extension set to the end of the cannula and remove the gauze, cleaning
any spilt blood
- Secure the cannula with dressing and if there is a third stripe attach with date and time of
insertion
- Unlock the lumen of the extension site and flush each lumen with 5mls of saline
- Re lock the lumen

TO COMPLETE
- Thank the patient
- Discard waste and clean the tray the discard gloves and wash your hands
- Complete a peripheral venous cannulation observation chart
