Advantage of ultrasound guided regional anesthesia methods.

• High success rate
• Safe performance of blocks
• Direct visualization of neuronal and adjacent anatomical structures
• Direct visualization of needle placement and spread of local anesthetics
• The individual blocks are cheaper in comparison with other techniques in regional anesthesia
• Amortization of high standard ultrasound equipment after 2500 blocks due to high success rates (with very low conversion rates to alternative anesthesia methods),
