Efficacy of Variable Lidocaine Concentrations in Tumescent Anesthesia for Pain Control During and After Endovenous Laser Procedure; a Double Blinded, Randomized, Controlled Non-inferiority Trial
Efficacy of Variable Lidocaine Concentrations in Tumescent Anesthesia for Pain Control During and After Endovenous Laser Procedure; a Double Blinded, Randomized, Controlled Non-inferiority Trial
Endovenous laser treatment is a minimally invasive procedure that has been shown to be a safe and effective treatment for varicose veins. Essential to the successful ablation of refluxing veins by endovenous laser treatment is the use of tumescent anesthesia. One of the components of tumescent anesthesia is lidocaine, a commonly used local anesthetic. While lidocaine can be used safely as long as serum concentrations remain low, its use carries the risk of lidocaine toxicity. In order to minimize the risk of lidocaine toxicity it is desirable to use the minimum effective concentration of lidocaine needed to manage pain during a procedure. This study seeks to determine if a ¼ lower concentration of lidocaine in tumescent anesthesia will function as well as the standard dose for pain management in endovenous laser treatments. If we find that this is the case, we will be able to reduce the risk of lidocaine toxicity in patients undergoing endovenous laser treatment, while maintaining their comfort throughout the procedure. This will be achieved through a direct comparison of intra- and post-operative pain for patients randomized to receive either the ¼ tumescent lidocaine concentration or the standard lidocaine concentration.
