How to Choose the Right Local Anesthetic for Your Needs

The relative risk of TNS when using lidocane versus bupivicane, methp Civicane, p acrylicane or procane is about four so four times as likely with lidocane. For peripheral blocks we use about one and a half to two percent methp civicane for short blocks like an AV fistula. And usually for a big upper extremity or lower extremity a big depot nerve block like a brachial plexus block or a femoral nerve block you can get up to 12 hours of pain relief from ropivicane and even up to 16 to 18 for bupanicane. Usually that's with 0.5 percent bupicularane
