Artificial-coloring in ultrasound-guided regional anesthesia.

Increasing the image quality and resolution while performing regional anesthesia under ultrasound guidance increases success and reduces complications. Artificial-coloring is one of the adjustments that can improve image quality. In our study, the results of coloring with blue were remarkable. However, more importantly than the color chosen, we believe that routine adjustments such as gain, depth, and focusing will bring important advantages.
