Venepuncture

Paediatric Anaesthesia Department

ZEN and the art of intravenous line placement

General tricks

1. It is all in the foreplay

  Get everything, and spares of everything ready.
  Swabs
  Cannulae
  Tapes
  Bungs or one way valves
  Arm boards
  Primed drip set

2. Have a good assistant who has done it before.

  They will have to hold the child (and limb) tight, pinned against some immovable object. Holding at a joint will not work. Two hands will probably be needed which is why everything must be ready and within arms reach.

3. Get comfortable & calm, preferably seated.

4. Find your vein

  Tourniquet on.
  Limb dependent.
  Tap over the vein
  Warm flannels may be helpful
  Skin traction  along the line of the vein will help immobilise it
(not so much as to collapse it)

5. Put the cannula in the vein

If at first you don't succeed

  If you are still calm try again.
  If you are rattled go away and come back an hour later
  Get someone else

Paedia-tricks

Let the child know exactly what you are going to do before each step.
Let them feel your confidence. Don't stuff them around and don't let yourself be stuffed around.
Parents are optional. Sometimes they are helpful sometimes they are not and there are no simple rules. If the child is less than 1 year old you are all probably better off without them.

EMLA needs to be on for at least ONE hour

Tape under the cannula, then tape over the cannula, to stop it flexing back on the skin

Where to look for veins

Limbs

  The forearm vein is not as useful in children as it is in adults
  Lateral aspect of back of hand
  Wrist is very painful and does not last for long
  Lateral aspect of the foot

Scalp veins

  Don't hit the artery...it is bad for the brain!
  The artery is usually pulsatile and tortuous
  Shave the head or you will never stick it down

External jugular

  Can be very hard to immobilise

Long saphenous

  A personal favourite
  Reasonably constant on the anterior aspect of the medial malleolus
  Can often be felt if not seen

Intra-osseous needles

  Play with one in peace time
  Tibial plateau is easiest

Trans abdominal

  Yucky but effective for rehydration
