Lidocaine 1% or 2%

  1. Ok a little question for you all. What do you use in your lab Lidocaine 1% or 2%. I personally am a fan of 2% just because if the procedure goes on for awhile, the patient don't start having pain. One of the nurses I work with is afraid, the patient might get toxic if we use 2%. I told her since it is more concentrated we will most likely use less in the long run. Also we used to use 2% to repair large lacerations in the ED. My theory is in this day and age patients should be comfortable.

    1% is choice of our Rads and Cards. "That's the way we've always done it." However, I'll have to poll them on WHY. Thanks for the brain shake.

    BTW, does anyone know exactly how many mg/kg of Lidocaine sub-q would be a "toxic" dose??? -- D

    I remember taking care of a post op c section that was emergent, started before anesthesia got there, used 2 1/2 bottles of 1% lido for local, she was on precautions for toxicity

    Only one of our Rads uses 2% and I'll bet its just out of long-time habit. Most of our pts seem to do fine with the 1%. The Rad will infiltrate the area with Marcaine 0.5% if the pt is having site pain or if the procedure is getting pretty long. A couple of our Rads use Bicarb to buffer the lidocaine, also. They swear it takes alot of the "sting" out of the Lido. I don't know if it really does or not and I'm not willing to be a guinea pig to find out!

    We use 1% unless we need more during a long procedure, then we switch to 2%.

    Lido really burns like ****. I have let the DR. Stitch up my forehead without lido, just cause the lido hurts more than the sutures.
