GENUINE LIDOCAINE ALLERGY

Last Updated: 1/11/2011

October 28, 2010 Dr. Ravi responds to Dr. Edmondson & Dr. Bush

I recently have encountered a patient with proven allergy to the xylocain preservative. Since then we have found a manufacturer who makes 2% xylocaine with epi. I am planning to use half the volume. We have done many with lidocaine allergy with ice cold ringer's or saline with no adverse effect. Can't do microphlebectomy.

Interesting problem although rare.

Dr. Mauriello has discussed this topic many times at the International  Venous Congress (IVC) in Miami. There is no cross reactivity among the lidocaine drugs. Hence, you should be able to use one of the other drugs such as marcaine or carbacaine without danger of allergic reaction. You might want to do a small test dose before just to make sure.

You need to use only small amounts of lidocaine drugs in the tumescent solutions.  As an alternative, try cold ringers lactate without the lidocaine drug addition. This provides good protection from any heat damage outside the vein and may be enough for analgesia alone.

I don’t blame you for doing this patient in the hospital with some mild sedation especially if you decide to go with the addition of marcaine etc..

I see no need for the use of general anesthesia.

You might want to contact Dr. Mauriello or Dr. Ravi who have used cold ringers lactate for the tumescent solution.

Please let us know on the blog what you end up using. I know from using cutaneous lasers that total anesthesia can be achieved by injecting sub-dermal saline at room temperature.

October 28, 2010 - Dr. Edmonson reports genuine lidocaine allergy

Young women with laryngospasm from nonpreserved 1% lidocaine skin wheal at start of 2nd leg GSV ablation 3 weeks after getting hives with standard tumescent infiltration of first leg. Responded to epi and dexamethasone. No known allergies prior to this pair of events.
Plan to do 2nd leg in hospital rather than clinic.
Do we use gen anesthesia and saline tumescent or premedicate with steroids and use another local such as carbacaine or procaine?

George Edmonson, MD
