EMCrit Podcast 210 – Arterial Lines (Part 1) - a podcast by Scott D. Weingart, MD FCCM

Today, we talk about arterial lines. I love arterial lines: monitoring, true MAPs, easy blood draw, easy blood gases, fluid status--what's not to love.



This turned into a 2-parter. Part 1 covers radial art lines

Here is Arterial Lines - Part 2

covers everything else below

Part 1 Covers:

Radial Arterial Lines

Peripheral vs. Central Arterial Lines

Sterility

Here is a systematic review of most of the literature



[cite]24413576[/cite]



My take on it is, use sterile gloves, mask, chlorhexidine prep, and if you can grab a fenestrated drape or some OR towels.

Technique



* Kit (The one I use is Arrow RA-04020)

* Ultrasound

* Threading

* How to Save it

* Allen Test



Securing

Tegaderm alone is not enough. I suture, but I really wish we had arterial line stat-locks



I always loop around the thumb and secure with tape outside of the tegaderm--I hate replacing pulled out art lines

Central vs. Peripheral Arterial Pressures

[cite]28523028[/cite]

Part 2 Covers:

Femoral

Sterility-Full Sterile



unless you are going for speed or the Dirty Double



Technique



Use Ultrasound



Find the Common Femoral Artery







 







Use of a central line kit?--No!



Back of wire? Check, but yes!

Axillary

Need Ultrasound

Brachial

Is it safe?
