Peripheral IV access using Ultrasound

Finding a vein can be difficult

…or easy

Studies have shown that with training:

1. Success for cannulation of peripheral IV is over 90%

2. Number of attempts to successful cannulation is less.

3. Therefore less traumatic to patients.

Why use ultrasound?

1. After 2 failed attempts at landmark cannulation.

2. Obese patients

3. IVDU

4. Pediatric patients

5. ? Trauma – may take too long.

When to use ultrasound

1. Difficult veins remain difficult veins

2. Use little pressure

3. Deeper vein, longer catheter

4. Failure to distinguish artery from vein

- compressibility, ?Doppler

- Brachial artery, nerve and vein are in close proximity – try to avoid.

5. Failure to identify nerve.

On the LMHER.com web page “Ultrasound Guided IV access” there is a 25 minute you tube video by Siegfried Emme that is very detailed but very good.
