Washing off local anaesthetic induced phrenic dysfunction following interscalene block

We read with great interest the recent article by Smith LM and Barrington MJ [1], who were able to successfully reverse local anaesthetic (LA) induced phrenic nerve paralysis by injecting saline down an interscalene catheter. While we concur their statement about “the technique of saline wash out of an interscalene brachial plexus catheter to reverse respiratory distress is a novel one”, we would like to point out that this “washing off” concept and technique have already been previously reported [2–5].
